1. SYNOPSIS

This report covers the acquisition of a Vibroseis sourced 2D seismic survey

undertaken by Tesla Exploration International Ltd on behalf of INEOS Enterprises Ltd

The survey lies within Middlewich in the Southwest, Northwich to the Northwest and

the M6 running South to North the area is known as the Cheshire Basin. The total

number of km acquired was 17.7Km.

The majority of the permit functions were carried out by the client’s land agent. The

land agents main involvement was to notifying all the tenant farmers of the Seismic

survey. TESLA provided a permit liaison officer to assist in locating the best access

points to the lines. Survey operations commenced on the 15th

November 2013, with

initial emphasis being placed on the setting out and programming of Lines.

Recording operation started on 18th

November 2013 and finished on 23rd

November

2013. All field based survey activity, including restoration and de-mobilisation of the

local field office, was concluded by 26th

November 2013.

The survey area was characterised by an area of gently rolling topography. Most of

the survey line were situated on cross country open farm land which keep the lines

straight.

The survey area was characterised by its central east west tarmacadam road A530

King Street and its network of smaller linking roads Drakelow lane, Yalehouse road,

Moss lane, Lilly lane and B5081.

2. OVERVIEW

The Permit Liaison Officer commenced permit activity in 11 November 2013. The main role

was to liaise with INEOS land agent, walk all line and review all accesses for Vibs and line

crew.

A local field office/base was established at Drakelow Hall Farm, Byley where the equipment

was also stored. The facility was situated central to the prospect area, ensuring the

travelling times to the furthest most points of the survey were within the acceptable time

frame. Electricity was provided through a generator supply and telephone communication

was provided by mobile telephones. Internet facilities were provided through dongles. A

clean, potable water supply was readily available on site.

Any roads affected by the majority of the traverse routes were of sound construction with

no apparent breaks or weaknesses in the tarmac surface. The roads themselves were either

quiet or extremely busy especially in the mornings and afternoons.

TESLA Base Camp

Client liaison was maintained throughout all aspects of the survey with Mr Jacques Bal (Geo

Stock) and Mr John Boundy who represented the interests of INEOS Enterprises Limited.




3. SURVEYING

Locations

Proposed Survey Routes




Actual Survey Routes

General

The survey party mobilised to the Holford 2D survey area on the 15th

November 2013. A

base office was set up at the Tesla yard at Drakelow Hall Farm, Byley. A GPS control station

was established at the base for use as a RTK base station using a Smartnet enabled GPS

receiver. The position was subsequently checked by INEOS to ensure compatibility with the

Holford survey network.

Surveying continued until the 20th

November 2013. The survey consisted of 17.7 km of

cross country Vibroseis 2D. Wooden pegs were used to mark receiver positions. Source

points were centred midway between two receiver points. Receiver stations were pegged at

a 20m horizontal interval, source was nominally programmed at alternate receiver points.

Source programs for the vib teams were produced for each line as the survey progressed.

Equipment

A Leica System 1200 ‘SmartRover’ RTK GPS receivers was available for GPS observations.

GPS observations are based on broadcast correction service via a GSM connection to Leica

‘SmartNet’.

‘SmartNet’ is enabled by the current network of Ordnance Survey base stations to create a

high density, high redundancy network. Data from over 100 of these base stations around




the country is received over the internet at a highly secure location in London Docklands

where it is processed using ‘Leica SpiderNet’, Leica Geosystems advanced network

calculation software, and made available directly in the field by a GSM connection. By

having the OSGB36 CSCS model and OSGM02 geoid model installed on the field receivers

direct output in OS grid and Newlyn Datum orthometric height is available.

Conventional RTK techniques based on the control station established by SmartNet was

used.

The GPS teams used a Land Rover 110 station wagon and a Ford Transit van to transport

personnel and equipment.

Field Ops

Lines were staked out using RTK GPS to position and survey the receiver stations. Vibrator

points were programmed for 1 vib, if any vibrator point was offset to the receiver line the

position was pegged and the position recorded.

Q.A.

The GPS log files for each day’s work were examined for errors in point numbering, receiver

height, co-ordinate quality etc. prior to insertion into the main database. The original data

was kept on backup files as a comparison. At the start and during a day’s work the teams

would log a measurement to either a point observed on a previous day or to a control

station. These points would be compared in the field and in the office for any errors in

either equipment or data input. All QA shots agreed within 0.5m X-Y /0.25m Z of previously

acquired positions, therefore no re-observations were required on this survey.

As the survey progressed the lines were overlaid using AutoCAD onto Ordnance Survey

raster maps then visually checked for positioning errors.

Computation

Raw data from the controllers were down loaded directly to the P.C. at the end of each

day’s work. .

The data were then converted to an ASCII file and exported to Leica ‘LISCAD’ for data

manipulation and terrain modelling.

885 receiver points on 4 lines were positioned and surveyed during the period, with a total

line length of 17.7 km.

4. RECORDING

Prior to the start of layout, all recording equipment cables and geophones were tested with

industry standard testers to manufacturer’s specification. This comprised using the Seismic

Source Bird Dog II geophone tester for geophone integrity. Megga insulation tester with the

geophone immersed in water and a GEOX cable tester for both the traverse line and

networking cables.

The recording instrument an Aram Aries system serial number SPM_440 supporting Aries

software version 3.108.01.02 also underwent a complete set of daily instrument tests to

ensure the system was working correctly, and a system diagnostic report (figure: 1) saved to

the system hard drive.

Figure 1: System diagnostic report

While the recording equipment was being laid out we moved onto the testing of the Aries

recording system timing against the Seismic Source Universal Encoder UE_ II electronics. The

Aries system AX program was then used to verify the timing of the source control system,

the Seismic Source Encoder against the recording instrument to ensure the correct time

delay was entered in order to achieve zero time delay between the recording system and

the encoder. The AX program was run several times in order to check the consistency of the

timing between systems. An average was taken and then entered into the Internal Start

window.

An Internal Start of + 1000046 µs was selected. The system time break check was also

selected with a +/- 20 µs entered. This represents a tolerance of acceptable time Break in

µs. When a Time Break occurs outside tolerance, a warning is displayed during the

acquisition process and the acquisition halted.

Auxiliary Channel Allocation;

For vibroseis operations 3 channels are available, due to previous seismic surveys recorded

in this area the optimum sweep parameters had already been selected and was then

processed on the Testif-I Check Reference sweep program, this program compares the

synthetic sweep with a recorded one and produces a number of plots (figure: 2 ) to show

how similar the sweeps are. After seeing both signals looked similar a stored Auto

Correlation (ACCOR) sweep was generated, this will then become the reference sweep. The

auxiliary channel assignments will be as follows:

Channel Auxiliary assignment

1 PTB (System Predicted Time Break)

2 True Reference (Pilot) 500 ms display delay

3 Wire line Reference

4 ACCOR Autocorrelation of stored reference 1000ms display delay




Figure 2: Plot showing the generated synthetic sweep frequency range 20Hz to 180Hz

compared to the recorded reference sweep.

Before the start of production a 100 Hz frequency test was also acquired by use of a Verif-i

precision clock. The precision clock is connected to a geophone takeout and then the 100 Hz

signal is recorded through the Aries recording system. This then allows the SEG Y file to be

processed on Testif-I software allowing the exact frequency recorded being displayed and

the PPM (Parts Per Million) error time shown ensuring the recording system master clock is




being checked (figure: 3). All 100 Hz frequency tests acquired by use of a precision clock

were then processed on Testif-i software shown below.

Figure 3: Processed 100 Hz precision clock record, showing a system error of -1.264 PPM. A

geophone tap test was also recorded to ensure we were recording SEG polarity. In order to

comply with the SEG polarity convention a tap on the top of a normally connected spread

geophone should result in a positive number on tape and an up-break to camera (figure: 4).

This was also used as a QC aid to ensure station positioning was correct.




Figure 4: The processed camera record showed an up-break in response to a tap on the top

of the geophone.

The nominal geophones spacing was a linear array with two strings of 6 geophones evenly

spaced over 20 meters with an element spacing of 1.66 meters. If for any reason the

geophones could not be laid in a full linear array due to obstructions there was several

alternative geophone patterns agreed with the client representative, these alternative

geophone arrays would be noted on the SPS files in order for the processor to spot any

irregularities. These patterns would be two strings of 6 geophones evenly spaced over 20

meters with an element spacing of 1.66 meters perpendicular on the peg cross-line because




of obstacles or if the incline over the array exceeded 1 meter in elevation, Two strings of 6

geophones bunched over 1 meter on the peg inline because of obstacles with an element

spacing of 0.09 meters, Two strings of 6 geophones bunched over 5 meter on the peg inline

because of obstacles with an element spacing of 0.45 meters, Two strings of 6 geophones

bunched over 10 meter on the peg inline because of obstacles with an element spacing of

0.90 meter, Two strings of 6 geophones bunched over 15 meter on the peg inline because of

obstacles with an element spacing of 1.36 meter. If we were unable to plant geophones due

to solid ground or obstacles, this station would be left open and recorded as a dead station.

The geophone station interval was 20 meters, the source points were nominally spaced at

40 meters additional VPs where recorded at the beginning and end of each line to give

extract fold of cover when stacking on and rolling off. Any programmed additional shots

could be recorded if necessary to compensate for shots omitted due to PPV readings or wet

ground.

Once there was enough line equipment laid out on receiver line IN-13-03 to give a sufficient

offset range we ran a set of daily tests. The Aries SPM recording filters were set at 3 hz to

205 hz @ 1 ms sample rate with a 30 dB preamp gain with a record length of 3 seconds, a

comprehensive set of daily tests was recorded on the entire line, this comprised of, Full

band, EIN, Impulse, Gain, THD, CMR, XFD for the Aries boxes. The geophones were also

tested for any channels responding irregularly, these tests consisted of Noise, Pulse,

Sensitivity, Resistance, Leakage, THD, Impedance and XFD. A daily system diagnostic test

was recorded to ensure the Aries system was working correctly. All the daily test results

were recorded as SEG files and made available to the client. Also prior to start of production

a noise strip was also recorded to tape as a daily monitor of the noise on active spread.

The vibrators were also tested, before the start of production a set of radio similarities

(figure: 5) were recorded on each vibrator to ensure its correct performance prior to

starting.

Figure 5: Radio similarity test vibrator 3 @ 50% drive level displaying phase within +/- 5

degrees of 180°




The VP points would be taken into a selected area known as the active patch; this area

would give sufficient coverage for the inline offset, depending on the VP point would deter

the amount of active channels nominally 75 – 75 symmetrical split with a 0 station gap on

the VP point allowing 75 active stations either side of the source point giving a maximum

offset of 1500 meters high and low. Each shot would be recorded into a separate patch; a

reduced patch was also used for stacking on and off.

The prospect area consisted of 4 source and receiver lines. The total survey area recorded

covered approximately 17.7 kilometers made up predominantly of cross country sections

with some vibroseis on roads and tracks. Receiver lines IN-13-01 and IN-13-03 crossed the

main A530 road and we had been instructed not to cross this section of carriageway with

conventional road mats. This was overcome by the use of a net-link (figure: 6), the net-links

would be setup either side of the carriage way and then allow data to be transferred back to

the Aries box below then through the cables to the recording truck The lines also crossed

the railway line and was network beneath the track by using an existing culvert.

Figure 6: Net-link setup crossing a busy trunk road.

Half way through recording on line IN-13-03 the client had planned to carry out a series of

sweep parameter tests to ensure the correct sweep parameter had been selected, these are

the series of tests listed below requested by the client in order to test alternative sweep

parameters. All test data was returned to base to be processed in order to confirm the best

sweep parameter.

tapers 250ms and end tapers 250ms linear, 3 sweeps, standing.

Once the parameter tests were complete it was confirmed that we had started production

with the optimum sweep but needed to increase the number of composites from 2 sweeps




to 4 sweeps per vibrator point to increase the data quality. We then did a complete set of

wire-line similarities on all 3 Vibrators model: I/O AHV IV-PLS362 at the preferred sweep

parameter; start frequency 20 hertz to end frequency 180 hertz with a sweep length of 10

seconds, sweep type linear with start/end tapers of 250 milliseconds to determine the

performance of the vibrators. The vibrators would connect their wireline similarity boxes

(DSU) to a geophone takeout and the Ground Force and True Reference signals recorded

through the Aram Aries recording system. This then gives the start time error between the

Vibrators electronics and the Seismic Source UE_II Encoder and the SEG Y file then

processed on Testif-I software, this would then plot the phase and distortion of each

vibrator (figure: 7) for individual machines and a multi-vibrator similarity (figure: 8) giving a

comparison of all vibrators.




Figure 7: Processed Testif-I Advance vibrator wireline similarity of vibrator 3 at 30% drive

level showing a start time error of 2 µs and total distortion, also the fundamental amplitude

in (Ib) expected at 30% drive level.




Figure 8: Processed Testif-I Multi-vibrator wireline similarities show a comparison of

performance between vibrators 2,3 & 4 at 30% drive level. The multi sweep analysis shows

the units comparison in phase, correlation and distortion.




The wet ground and the shortness of the 10 second sweep, sweeping through the frequency

range 20Hz to 180Hz contributed to the high levels of distortion. The vibrators were

constantly monitored in production and the Post Sweep Service (PSS) displayed and

recorded. At time the drive levels needed decreasing to reduce the distortion levels being

reported. A road sweeper was also used to ensure any mud from the vibrators was cleaned

from roads and private tracks.

The data quality throughout the prospect had been variable with a combination of good to

fair records, 99% of VP point were cross country with the higher drive levels achieved where

possible without exceeding distortion tolerances, and variable drive levels close to areas

with services and PPV monitoring of buildings, houses, HP gas pipelines, so the drive levels

would be reduced in order to comply with Tesla Exploration International Limited

recommended safety distance limits. All buildings required PPV monitoring to ensure that

the vibrations from the vibrators did not cause any damage to property within close

proximity of the source line. If PPV levels reached the Tesla recommended safety limits,

drive levels or number of vibrators was reduced to ensure no damage.

The observer would monitor each shot record for noise or channels responding irregularly.

All monitors were delivered along with a comprehensive daily log to the office for

generating the daily report and daily SPS files produced for data QC.

Small isolated sections of noise were experienced on all traverses, predominately adjacent

to farm buildings and dwellings and close proximity of the railway line. On all lines there

were a number of road junctions and intersections which also contributed to higher levels of

random noise, due to the high volume of traffic on the busy A530 main road.

All recorded data was stored on LTO Ultrium 2 cartridges, all data was backed up and CD’s

produced containing all SPS files and copies off all daily tests and observers reports. All was

shipped on completion of recording to processing

The final day of production was 23rd

November 2013. Once we had finished recording this

then released all the line equipment and the line crews started the picking up of cables and

geophones. All equipment was then returned to base to be counted and packed.




5. HEALTH, SAFETY and ENVIRONMENT

Overview

The full implementation of TESLA EXPLORATION’s Occupational, Health and Safety

management system (OHS-MS) was applied by ensuring adequate meetings, auditing, risk

identification and analysis, reporting, control and follow up was maintained on a regular

basis. This resulted in the completion of the project with the target of Zero LTI achieved.

Before the commencement of the project, the TESLA EXPLORATION crew management

produced a PROJECT SPECIFIC HSE PLAN, specific to the location, terrain and legal HSE

requirements of the United Kingdom, Europe and industry guidelines (OGP/IAGC). TESLA

EXPLORATION management on the crew made every effort to ensure that the Health, Safety

and Welfare of the crew personnel were maintained at the highest possible level. This also

included the prevention any foreseeable environmental damage that could occur during the

course of the seismic survey.

From the first day to the end of the project, TESLA EXPLORATION Crew 1190 provided all the

necessary HSE requirements to the crew personnel and sub contractors.

The HSE Advisor on the crew used the TESLA EXPLORATION HSE Management System

manual in accordance with the local conditions and associated HSE legal requirements.

Throughout the operation, successful identification of hazards and risk control enabled all

operations to be completed in a completely safe and timely manner.

The Party Chief promoted the benefits of safe work practices and visibly demonstrated his

commitment with regular participation in HSE activities. By doing so, he presented a positive

message to both the senior and junior staff.

There were visits from both INEOS ENTERPRISES LTD and TESLA EXPLORATION LTD senior

management during the course of the survey. All parties demonstrated their support and

commitment to the crew regarding HSE matters.

Overall, TESLA EXPLORATION crew 1190 produced a high quality product whilst maintaining

a safe and environmentally friendly working atmosphere.

HSE activities:

Total Man-hours exposure for the contract: 3,000

Total LTI free hours for the contract: 3,000

Total Miles driven: 7,934

Total recordable incident cases: 0

Medical Treatment Cases: 0




First Aid Cases: 0

Restricted Work cases: 0

Inductions: 41

Toolbox Talks: 10

Safety Meetings: 4

Stop cards: 4

Safety Observations: 3

All visitors received an orientation HSE induction and were supervised around the prospect

area.

First aid kits for all vehicles were inspected and refilled prior to the commencement of the

works.

Both the base and office locations were supplied with adequate first aid and welfare

facilities.

TESLA EXPLORATION carried out total of 2 audits/inspections with regular observation

reports.

All crewmembers received a full HSE induction on arrival at the crew base.

All crewmembers received the relevant PPE and training on the use and care of the items

before starting work.

All representatives of the client, subcontractors and TESLA EXPLORATION management and

crewmembers were encouraged to attend the daily toolbox talks.

All vehicles were issued with a copy of the crew ERP (Emergency Response Procedures).

Comprehensive vehicle checks were carried out on a daily basis by all of the designated

drivers.

All vehicles were also supplied with a copy of the expected HSE standards as set out by

INOES ENTERPRISES Ltd.

A fire prevention check was carried out on all of the fire extinguishers prior to the start of

operations.

HSE toolbox meetings:

An essential part of the HSE management system requires the transfer of information and

feedback from crew level. This was achieved through regular crew toolbox meetings.

Tool Box Talks.

Environmental Considerations

The crew worked within the guidelines as set out in the TESLA EXPLORATION environmental

policies.

The following general instructions were explained to the crew:

To minimize all travel, particularly along the off road traverse routes by making use of good

daily planning.

All rubbish and waste material to be returned back to the base facility at the end of each

working day.

Oils and fluids are not to be changed or replaced in the field.

A spill containment system should always be in place wherever there is storage of oils and

other lubricants and chemicals.

All operations are to be carefully planned to minimize disturbance and effects to flora and

fauna.

Chance finds of habitats are to be marked on a map and avoided.

Acts of interference and vandalism by the workforce would not be tolerated.

Waste segregation rules and line clearance regulations were complied with. All surveying

pegs, markers and bunting was completely removed from site.

Emergency response procedures

A range of contingency plans were developed on crew, to apply in the unlikely event of

emergency situations such as fire, illness or injury and oil spill etc. These emergency plans

were processed and posted in the mess, offices and a copy provided for each vehicle.

Instruction was also given for all personnel/visitors relating to the plan at the initial

induction phase.

Emergency Drills

The objective of the drills is to determine the efficiency of the response of the crew to

control an emergency situation, to check the readiness of the team responsible for

controlling an emergency and to test available equipment.

Flow diagrams outlining the emergency response structure and advising contact numbers

were posted on the office notice board, the recording unit and mess facility.

Safety advice notices were also posted on the mess notice board.




Instructions in case of Fire were placed by room exits.

Emergency MEDEVAC procedures including the INEOS instructions were posted in all of the

vehicles and in the Party Chief’s office.

All relevant TESLA EXPLORATION policies were posted on the main notice board. Prospect

site-specific hazards were also posted on the main notice board.

Vehicle Management

Vehicle movement/transportation is always identified as the most hazardous operation on

land seismic crews. Because of the high potential for vehicle accidents it was recognised the

whole crew had to be actively engaged in its prevention.

Due to the nature of the ground on some of the survey lines, Polaris Rangers were used to

minimize damage to the environment. Before commencement of operations all Rangers

were fitted with measures to ensure that they were road worthy and legal. All Ranger

drivers had received the relevant training before the contract started and a copy of their

qualifications kept on the crew training records.

During normal operations drivers kept the senior observer informed of their location.

Throughout of the project, radio communication and mobile telephone signals were good

including reasonable access to the Internet.

Security

The operations base was in a rural location within the confines of a local farming operation

near to the village of Byley. A security patrol was maintained during the hours of darkness

and no vandalism or theft was reported throughout the whole of the operation.

Safe passage for pedestrians was maintained at all times. Noise was also kept to a minimum

during working hours to ensure good relations with neighbours.

Ramp signs were placed on roads where cables crossed. The cables where protected in

rubber cable mats.

All hazards were clearly marked and visible to all personnel on site. Other work activities

from the owners of the farms did not interfere or cause any hazards to the crew.




Internal Inspections

2 audits and inspections were completed during the course of the survey. The crew HSE

Advisor carried one of the audits out and the TESLA EXPLORATION management team, who

visited the crew, conducted the other inspection.

The HSE advisor made daily visits to the field operations to observe and monitor the

activities of the crew. When examples of bad practice and unsafe actions were observed,

the work was stopped and the correct procedures were explained, demonstrated and

implemented.

The client representative also conducted frequent observations of the field operations and

gave valuable feedback to the crew management.

Findings for recommended corrective actions were mainly provided by the completion of

STOP cards. The results were discussed at the following toolbox meeting on the next day.

Vehicle related incidents and LTI’s

For the period of the contract (November 15th- November 24th 2013), there were no

accidents/incidents resulting in lost time due to injury.

Key Performance Indicators

Daily safety statistics were recorded by the HSE Advisor and forwarded to the Crew

Manager who compiled a crew daily/weekly/monthly report.

Vibration monitoring

During recording operations regular vibration monitoring checks were carried out (PPV).

Monitoring results were recorded and logged when operations took place near to any

buildings and services in the prospect area. TESLA EXPLORATION will keep all findings on file

in the unlikely event of any civil litigation that may arise at a later date. The client

representative has also retained copies of the files.

Crew Medical Care

The nearest Accident & Emergency hospital facility and a local doctor’s surgery to the

prospect area were identified the same day on arrival, or as soon as possible. All crew

personnel were made aware of this by means of the crew’s toolbox meetings, Emergency

Response Procedure (ERP) and initially on their induction. The crew had 13 1st

Aid trained




personnel on call at any one time. A list was produced and placed on the HSE notice board

in order for the crew to fully understand who their nearest first aid trained operative was.

Observation and analyses

Statistics showed a total of 7 stop cards given to the HSE department. The stops cards that

were given to the HSE department were of a high quality and did assist the crew in the

development of risk reduction measures. Intensive efforts were made by the crew

Management team to improve hazard reporting by ensuring this was a regular subject at

safety meetings.

Encourage should be given to the lower ranked members of the workforce. His or her

superiors should impress the ‘blame free’ attitude on each individual.

TESLA EXPLORATION is committed to the provision of adequate and suitable PPE (Personal

Protective Equipment) for its employees.

6. PERMIT

The Permit Liaison Officer commenced permit activity on 11 November 2013. The main role

was to liaise with INEOS land agent, walk all line and review all accesses for Vibs and line

crew.

Line IN-13-03 was walked first to identify any potential issues with line positioning and

vibrator access. During a subsequent meeting with Robert Hodson, INEOS permit man, and

John Boundy, INEOS project manager, all were made aware of the issues identified and the

adjustments that were required to access the lines. Once the changes were confirmed all

fields were walked again and marked with bunting to showing the access. This was repeated

for each line.

After some very heavy rainfall re-examination of field access was required for all lines and

some adjustments were identified. The first line to be shot was walked with John Boundy

and Jacques Bal to demonstrate how access would be gained in flooded fields and

agreement was reached on routes to be used to access the lines to lessen environmental

impact.




A meeting at INEOS offices was arranged to clarify progress, Tesla also received further

maps and service plans during this visit.

Meetings were arrange with the HP gas pipeline representative and helped to mark the

pipelines on site in preparation for our programming, The Fuel pipeline representative who

helped to mark the pipelines on site in preparation for our programming.

8. CONCLUSIONS AND RECOMMENDATIONS

The survey was completed to the instructions of the Client, with data quality ranging from

fair to good.

Fold of cover was maintained.

The impact on the local community was minimal with many farmers and land owners

complimenting the crew on its methods of operation, diligence and efficiency.

All HSE tools were used to good effect, with stop card being discussed at toolbox meeting

insuring that everybody being made aware of any hazards.

The survey was successfully completed without any lost time incident or accident being

reported during all operational phases.
