SUMMARY

A number of cement jobs were performed by Halliburton

Services beginning February 28 through March 3, 1991, to set

cement plugs in an attempt to stabilize a fractured zone in the

rock formation between 1,688-1,765 feet, which was causing a

total loss of drilling fluids. On March 5, geophysical logs were

run in the hole by personnel from the united States Geological

Survey (USGS). Logs included: temperature, gamma, caliper,

spinner and televiewer (bottom hole temperature was 85° F).

Rotary drilling of the 8-1/2" hole proceeded from 1,871-1,901

feet in a fairly competent formation until a number of drill

collar failures occurred due to a sudden deviation ("dog leg") in

the hole in the 1,870-1,900 foot interval. 7 inch casing was run

to 1,896 feet and cemented and coring with HQ equipment began on

March 17 and advanced from 1,909-1,924 feet in dense basaltic

intrusive rock. Due to short core runs through poorly

consolidated, fragmented rock, core drilling was abandoned and

rotary drilling resumed on March 20, 1991, with a 5-7/8" rotary

bit. Rotary drilling proceeded from 2,046-2,966 feet and will

continue until a more competent formation is encountered and then

casing will be run in the hole and core drilling resumed. A

fence was erected around the SOH-1 wellhead on March 29 and the

sump material is being analyzed to determine if it is suitable

for disposal at the County landfill or if it should be buried on

site. SOH-3 remains in the permitting stage awaiting a grading

and grubbing permit.

I. INTRODUCTION

This document presents a monthly report to the County of

Hawaii Planning Department to support the Scientific Observation

Hole (SOH) program in the Kilauea Middle and Lower East Rift

Zones. The SOHs are for scientific observation purposes only.

The holes will not be flow-tested or produced. The information

to be gained from the SOHs will provide an assessment of

subsurface geological conditions, groundwater level and

composition, temperature, drilling conditions, an inventory of

possible mineral and geothermal resources, and an eruptive

history of the island to the depth drilled.

This report addresses: occurrence and duration of any start­

up, shut-down, and operation mode of any SOH/facility;

performance testing, evaluation, calibration checks, and

adjustment and maintenance of the continuous emission monitor(s)

that have been installed; and emission measurements.

II. BACKGROUND

The County of Hawaii Planning Commission approved, on

August 8, 1989, a geothermal resource permit application

(GRP 89-1) to drill Scientific Observation Holes (SOHs) in the

Kilauea Middle and Lower East Rift Zone. This document presents

a monthly report, as required in Condition 6:

"The petitioner shall maintain a record in a permanent form

suitable for inspection and five (5) copies shall be filed

with the Planning Department on a monthly basis during

drilling and for six (6) months after the completion of

drilling to establish a hole specific baseline and such

record shall be available to the community. The record

shall include:

a. Occurrence and duration of any start-up, shut-down, and

operation mode of any SOH/facility.

b. Performance testing, evaluation, calibration checks,

and adjustment and maintenance of the continuous

emission monitor(s) that have been installed.

c. Emission measurements reported in units compatible with

applicable standards/guidelines."

As designated, four holes are planned to be drilled along

the Kilauea East Rift Zone on the Big Island of Hawaii. Three of

the Big Island holes (SOHs 1, 2, and 4) are on agriculture land

and have been permitted by the county of Hawaii Planning

Commission. The fourth hole, designated SOH-3, is on

2

conservation land. SOH activities under Conservation District

Use Permit (RA 12/20/85 - 1830) issued to the Estate of James

Campbell have been approved.

III. SOH-1 SITE

Drilling Activity

Drilling is complete. The County of Hawaii, Department of

Water Supply removed the water meter, which had monitored the

water usage for the drilling operations at the SOH-1 site, on

March 25, 1991. A fence was erected around the SOH-1 wellhead on

March 29, 1991. The sump material is being analyzed to determine

if it is suitable for disposal at the County landfill or if it

should be buried on site. The site will be reclaimed to its

original state after testing and monitoring are completed.

Monitoring Program -

Air Quality, Meteorological, Noise and Emissions are not

monitored, as drilling has been completed at this site.

IV. SOH-2 SITE

Tonto Drilling Services continued drilling activities from

1,871 to a depth of 2,966 feet (1,095 feet) for this reporting

period. A number of cement jobs were performed by Halliburton

Services beginning February 28 through March 3, 1991, to set

cement plugs in an attempt to stabilize a fractured zone in the

rock formation between the depth of 1,688-1,765 feet, which was

3

causing a total loss of drilling fluids. On March 5, geophysical

logs were run in the hole by personnel from the united states

Geological Survey (USGS). These logs included: temperature

(bottom hole temperature 85° F), gamma, caliper, spinner and

televiewer. Rotary drilling of the 8-1/2" hole proceeded from

1,871-1,901 feet in fairly competent formation until a number of

drill collar failures occurred due to a sudden deviation ("dog

leg") in the hole in the 1,870-1,900 foot interval. 7 inch

casing was run to a depth of 1,896 feet and cemented. Core

drilling with HQ equipment began on March 17, 1991, and advanced

from 1,909-1,924 feet in dense basaltic intrusive rock. Due to

short core runs through poorly consolidated, fragmented rock,

core drilling was abandoned and rotary drilling resumed on March

20, 1991, with a 5-7/8" rotary bit. Rotary drilling proceeded

from 2,046-2,966 feet and will continue until a more competent

formation is encountered and casing will then be run in the hole

and core drilling resumed.

Monitoring Program - Air Quality

The air quality monitoring station provides a continuous

record of atmospheric HzS concentrations when interfaced with a

data logger or chart recorder. The unit is located in a utility

container on-site and power is provided by the drill rig system.

This station required minor adjustment and the replacement

of some components during this report period. On March 22, 1991,

4

an extensive calibration adjustment was made and for the rest of

the month the monitor operated normally (see appendix for

details).

Monitoring Program - Meteorological

continuous wind speed and directional measurements are being

made with a recording wind speed/direction sensor system. A data

logger and back-up pressure-sensitive recorder is being used to

record the wind speed and direction data. The unit is located in

a utility container on-site and power is provided by the drill

rig system.

This station operated normally through the month with minor

adjustment and calibration. A chart jam occurred on March 13,

1991, resulting in the loss of some data (see appendix for

details).

Monitoring Program - Noise

One noise monitoring station is located at the SOH-2 site

during drilling and is operated by power provided by the drill

rig system. This station operated normally through the month

with minor adjustment and calibration. On March 22, 1991, a new

battery was installed (see appendix for details).

A second noise station is located at the Perry residence,

5

about a third of a mile north of the SOH-2 drill site. The

instrument at this station is powered by solar charged batteries

and operated normally for the month with minor adjustments and

calibrations (see appendix for details).

A third noise monitoring station is located at the Hedtke

residence, about 0.4 of a mile east of the SOH-2 site. This

monitor is powered by solar charged batteries, which required

replacement due to a weak charge. All five (5) batteries were

replaced on March 15, 1991 (see appendix for details).

Emissions Reports

An HzS monitor is located on-site. The average HzS level

measured is about 1 ppb due to natural causes resulting from the

decay of vegetation. Colortek sensor canisters are located

around the perimeter of the SOH-2 drill site and are replaced

weekly as a matter of routine. The sensors showed no indication

of any emissions from the well.

v. SOH-3 SITE

No drilling activity has been initiated. Access to the

SOH-3 site has not been constructed, nor has the site been

cleared or graded. SOH-3 is scheduled to be located at the

True/Mid-Pacific alternate drill site 2 (approximately 3,000 feet

north-north-west of the present drill site). All necessary

reports have been submitted to DLNR for review and approval. An

6

expanded archaeology survey on the Buffer Zone surrounding the

proposed SOH-3 site has been completed and was submitted to DLNR

on March 19, 1991.

VI. SOH-4 SITE

Drilling Activity

Drilling is completed. No activity was performed during

this period. The Landowner, Campbell Estate, has seeded the site

with experimental Mamaki, Kopiko, and Ohia seeds collected from

plants in the nearby area.

Monitoring Program -

Air Quality, Meteorological, Noise and Emissions are not

monitored, as drilling has been completed at this site.
