1 The Ministry of Environment and Forests has examined
your application. It is noted that M/s Gujarat Petroleum
Corporation Ltd. along with GAIL and JTI inc. have
proposed for on shore exploratory drilling for oil and gas
in CB-ONN-2003/2 block in Ankleshwar, Gujarat. The
block is geographically divided by NH 8 in the West and
east part. Narmada, Kaveri and Amaravati rivers are
major water bodies in the area. Total area of the block is
about 448 sq km. The unit proposes to drill 24 nos of
exploratory wells which will be drilled to a depth of 1500
m – 2500 m. The approx land area required for drilling
of each well will be 110 m 8 110 m. Water based drilling
mud will be used. Cost of drilling per well will be Rs. 10
crores. Expenditure on Environment Management
scheme per well will be Rs. 2.70 lacs
The details of onshore exploratory
drilling wells in CB – ONN – 2003/2
is as mentioned in Annexure A
2 The water requirement of 44 KLD will be sourced from
the Ground water. About 10 m3/day of waste water in
the form of washings will be generated during the drilling
operations from a single well which will be collected in
HDPE lined pit at drilling site for solar evaporation.
Domestic waste water will be disposed off through septic
tanks. Power requirement of 440 KVA will be met
through the DG set. Approximately 150 liters/hour of
HSD will be used as the fuel for DG set. Solid waste will
be generated in the form of drill cutting (224 MT), oily

EC COMPLIANCE REPORT
Contingency Plan for Handling H2S
The possibility of Presence/release of Hydrogen Sulphide (H2S) gas is almost negligible in this Block. Even though the Multiple H2S detectors will be installed at different places at drill site for detection of presence of H2S during drilling operation as precautionary measure. Monitoring of H2S gas will be practiced frequently during drilling activity and data will be maintained at site.
The purpose of this contingency plan is to educate the employee for H2S identification and to reduce hydrogen sulfide (H2S) exposure to below the Permissible Exposure Limit.
H2S Characteristic
Color Colorless Odor “Rotten eggs” (detectable at 10 ppb) Toxicity Highly toxic
Flammability Flammable
Solubility 0.4%
Incompatibilities Strong oxidizers, strong nitric, acid, metal
Exposure to hydrogen sulfide above published limits can result in adverse health effects including:
• Eye irritation • Lung effects • Central Nervous System effects on parts of the brain that control breathing • Shock, convulsions and death at high exposures
Symptoms of hydrogen sulfide exposure include:
• Eye irritation • Nose and throat irritation • Headache, dizziness • Nausea • Cough, breathing difficulty
Exposer Limits:
Permissible Exposure limit (PEL) for H2S is 10 ppm for eight-hour time-weighted average (TWA8) or 15 ppm for Short Term Exposure limit (STEL) as averaged over 15 minutes.
EC COMPLIANCE REPORT
Contingency Plan for Handling H2S
In case of unexpected release of H2S gas below Guidelines to be followed.
• The person detecting the H2S must IMMEDIATELY notify the driller. The
driller will, in turn, notify the Toolpusher and/or the Drilling Superintendent.
• The drilling operation will be stopped immediately untill the drill site will be
decleared free and safe from H2S.
• Hold their breath if air breathing equipment is not available;
• Rapidly evacuate the area containing the H2S and move crosswind direction
move up assembly point or safest area.put on a BA by only trained person;
• Evacuate anyone who may be affected by the gas to a safe area; administer
resuscitation or oxygen as needed or seek external medical aid at nearest
hospital
• Put on air breathing equipment before helping anyone overcome by H2S;
• Quickly evacuate to the assigned or announced safe-briefing area to receive
instructions from supervisory personnel; and
Don’t create/be panic.
Monitoring / Observation During Specific Operations
During drilling operations the H2S levels indicated by the monitors must be continuously observed during the following operations after penetrating a zone where H2S was identified during drilling:
1. When pulling a wet string of drillpipe
2. When circulating bottoms-up after a drilling break
3. During cementing operations (including abandonment)
