A1.3 Weather, Currents & Tides The area is prone to fluctuating tides and marine currents. The information regarding weather, bathymetry, current and tides, fishing activity and obstructions provided in this document are based on the operational experience of the ONGC-VL and the available public domain data as broad guidelines. Contractor is required to ascertain the same from its own sources. The fair weather window in the local area is from May to November

70

A1.4 Bathymetry, Obstruction and fishing activities

The CONTRACTOR is expected to familiarize themselves with the seabed bathymetry, seabed obstructions and water depths in the area well before operations commence. Presently there is no rig / platform in the area. There is no information on subsea obstructions.

Fishing activity is expected in the area. Fishing vessels are generally small vessels with limited crew and capabilities, few vessels will have both radar and radio facilities. Appropriate planning with the local fishing community will need to be implemented by the CONTRACTOR and adequate number of chase vessels will also need to be employed by the CONTRACTOR at its own cost. Managing the fishing activity in the area is CONTRACTOR’s responsibility.

A1.5 Environmental Issues There are particular environmental constraints, like Mammals were seen while 2D Seismic Surveys. Fishing and commercial shipping activities may restrict operations. The acquisition should be planned to minimize these disruptions. The representatives of local environmental or fishing interests may also be required onboard. In addition representative(s) from DIMAR may also be required onboard the mother boat and or on one of the chase vessels. The CONTRACTOR will also be expected to liaise with the local fishing community in a constructive manner to ensure they are kept fully informed of operations to reduce the infield risk.

On one channel an oscillator signal of amplitude approx. equal to the maximum permitted noise [RMS amplitude equal to 7 microbar x cable sensitivity (micro volt/microbar)] will be recorded for reference purposes. Playbacks of these records will be made in fixed gain such that the camera traces have sufficient amplitude to enable noise measurement to be made. These noise strips will be annotated with date, line no., propeller rpm and pitch, boat speed, sea state and direction. The average noise level and any anomalous group will be noted on the observer’s log. Streamer noise will be given in micro-bars RMS and measured over the full recording cycle with recording filters and with the streamer at the specified tow depth.

g) At the operating depth (7 to 8 m) the ambient cable noise shall not exceed 7 micro-bar rms for a group length of 12.5m. For groups closer than 250 m from the vessel and for three groups nearest to the tail buoy, the ambient cable noise may exceed the specification, but should be within 14 micro-bar rms. The maximum noise levels for groups adjacent to depth controllers shall not exceed 14 micro-bars rms. For shallow water blocks where the streamer needs to be towed at shallower depth, the ambient cable noise permissible is upto 20 micro-bars. All groups that fail to meet the above specifications will be regarded as bad and will be marked as such on the observer’s log. Higher noise levels due to factors beyond the CONTRACTOR’s control (e.g. nearby seismic operations, drilling activity or adverse weather conditions) may be acceptable but only at ONGC-VL’s representative’s discretion. All such instances will be fully documented on all relevant observers’ logs.

As a general guideline, average swell noise of up to 25 µbar on 5% of shots per line for less than 2 seconds duration may be tolerated. Effects of swell noise will be evaluated using onboard QC system. Higher noise levels may be acceptable subject to QC REPRESENTATIVE’s approval.

Coherent noise shall be assessed according to the following:

80

• Amplitude of the interfering signal • Duration of the noise • Repetition and synchronization of the interference • Moveout of the interference

• Constant interference upto 10 µbar may be acceptable up to a maximum duration of

4 seconds. • As a general guideline, coherent noise should not exceed the following limits:

Noise coming from astern and ahead of the streamer:

Slope Max. Noise (µbar RMS)

12.5m group 25.0m group More than 300

msec/km 28 µbar 20 µbar

150-300 msec/km 14 µbar 10 µbar 0-150 msec/km 6 µbar 4 µbar

Coherent noise sources should be identified and logged. Action should be taken to ensure shot to shot timing differentials of the noise exceed 500 msec. Coherent noises that consists of horizontal reflected energy from the acquisition vessel is to be exempted from the specification.

Noise coming from the beam (or side) can be particularly harmful and difficult to deal within processing. In general terms, only low levels of interference from the beam may be accepted for short duration within a record. In these situations the use of onboard QC/processing systems are necessary to fully evaluate the effects on the data.

h) The streamer will be balanced for neutral buoyancy. This will be checked prior to the start of survey to ensure that it runs at the specified operating depth with the boat steaming at normal shooting speed.

i) The birds will be displaced as far as possible from section hydrophones to minimize noise. The operation of the birds will be checked on deck before deployment.

j) Noise record of shall be taken both on cartridge and monitor record before start of line and after end of line.

k) Standard instrument tests as specified by manufacturers shall be carried out daily. Deficiencies must be corrected and verified before work commences.

l) Streamer continuity and leakage tests shall be done before start of each line

A.16.2 Acquisition Procedures and Minimum Line Lengths

• Line run-in distance shall be sufficient to ensure there are no residual noise or turn effects present in the streamer shape and that the gyro compass has had time to settle. In any case in the absence of physical constraints, the minimum run in distance shall not be less than the length of tow (unless constraints by physical obstacles e.g. bathymetry). Note that far offsets will be required at the edge of the survey full fold area and binning criteria must be met right up to the edge of the survey.

• Guns will be fired in sufficient time prior to start of line to allow for warming up and

tuning.

81

• In areas where Cetacean activity is of concern, a phased startup of the guns shall be

implemented on the run-in to line such that output is increased progressively in sufficient time prior to start of line.

• Line run outs to achieve full fold coverage are required at the end of each line and

should not be less than ½ active streamer lengths plus ½ sources to near trace offset.

• As far as possible all lines shall be recorded in one pass.

Any line terminated within a distance equivalent to the streamer length from the start point shall be re-acquired in its entirety (except for in-fill lines).

Unless otherwise dictated by operational constraints the maximum number of allowable line segments per line shall be:

Line length < 20 km: 2 segments Line length 20-35 km: 3 segments Line length 35-50 km: 4 segments Line length > 50 km: by agreement with QC REPRESENTATIVE

Any line re-shoot shall be recorded in the same direction as the original line.

All efforts will be made to ensure that infill recording is acquired in the same direction as the primary line.

A.16.3 3D Quality Control System-Specification & Standards

a) The system should have sufficient disc memory and capable of dividing the survey area

into the requisite storage bins, and store all offset coverage in a permanent grid database.

b) The system shall be capable of providing hard copies of partial and total grid coverage

plots or listings in order to determine whether or not sufficient offset coverage has been obtained. The system shall provide a track plot of cable midpoint angles throughout a line.

c) The system shall have the ability to recalculate the grid data if cable compass or navigation data is found to be below specifications or if particular lines are to be added or subtracted from the database. ONGC-VL has the option of not adding the data to the grid base after a line has been shot.

d) The system should allow for dividing the streamer into a minimum of 4 segments and furthermore shall have the capability of verifying that the specified offset distribution has been achieved.

e) Facility for automatic rejection of bad compasses in real time should be available.

f) The system shall be capable of providing a display in real time of the midpoint distribution of reflection points from each streamer segments.

82

g) All midpoint coverage data shall be recorded on cartridges in case of a failure within the

data base storage system.

h) Work shall not commence or continue on any line if the Gyro compass or equivalent heading system is not operational.

i) Out of 20 compasses in each streamer (streamer length 6000 mts, prorated for shorter or longer streamer length) a minimum of 15 shall be operational at all times when data acquisition is taking place. Of these 15 compasses, one each shall be at the near and far ends of the streamer.

j) Manufacturer’s specifications of all cable compasses shall be verified prior to and on completion of the survey to establish individual compass bias. Compasses exhibiting dynamic biases in excess of 0.5 degrees shall be considered bad and shall not be used.

k) A cable compass shall be considered bad if it gives more than five successive bad values

or more than 15% of its reading are bad on any one line. l) Swell Noise of up to 25 micro bar can be tolerated if appearing on less than 5% of shot

records on any line and is less than 2 seconds in duration. m) Mid-Point Coverage

i) The data shall be collected utilizing fixed sub-surface gather bins to obtain a nominal fold per CMP coverage as per Clause A.10. Each fixed sub-surface area gather bin shall contain a minimum number of traces segment wise as follows:

90% of all midpoints from the near quarter of the streamer 80% of all midpoints from the second quarter of the streamer 70% of all midpoints from the third quarter of the streamer 60% of all midpoints from the fourth quarter of the streamer

The above shall be achieved after removal of all bad traces/ channels; bad shot points, duplicate offsets and flexible binning of 25% on the first group tapered linearly to 100% for the last group.

ii) If required, the vessel may steer off the pre-plotted line to compensate for

streamer feather due to tides and currents to provide optimum midpoint coverage. Quality Control of sub-surface coverage and bin content shall be carried out by CONTRACTOR’s personnel onboard the vessel.

iii) In areas having obstructions like Rig and Platform, there will be hole in 3D mosaic about 500 meter radius of the obstruction, which will be accepted by ONGC-VL.

iv) Infilling Every effort shall be made to meet the above specifications A16.3 (m) without infill lines. The payment for infilling shall be regulated as under - Infilling up to first 20% of primary acquisition in each block will be

payable by ONGC-VL - Infilling beyond 20% and up to 30% of primary acquisition in each

block will be to CONTRACTOR’s account, - Infilling, if any, beyond 30% of primary acquisition in each block will

be payable by ONGC-VL.

83

To work out the number of infill lines actually in-filled, following procedure shall be followed:

• The coverage plots before and after each in-fill sequence (or the difference coverage plot) in respect of all four quarters of streamer, shall be provided by the CONTRACTOR to onboard ONGC-VL’s representative.

• The length of each actual infill CMP line in a particular quarter shall be pro-rated w.r.t. to full in-fill sequence length (excluding run-outs, falling outside the full foldage boundary, if any). A sum of all such pro-rated in-fill CMP lines shall be worked out for that quarter. Similar computation will be done for remaining three quarters also.

• The sum so arrived for all quarters shall then be summed and divided by four (4) to arrive at the number of CMP lines, actually in-filled for a particular in-fill sequence.

• The total number of CMP lines, actually in-filled will not exceed the product of streamers used and the number of sources for a particular in-fill sequence.
