slide7. 7 Product Details:
Drilling of 35 hydrocarbon wells.
Development of 10 well pads to setup the hydrocarbon processing facilities
Produce up to 30,000 Barrels of Oil per day and 30 Million Metric standard Cubic Feet of gas per day.
Laying of separate gas pipeline from the developed well pads and connecting to the main header pipeline already laid by GAIL and MEGHA.
Well Design:
Well design will be three casing policy.
The initial casing will be ~ 600 m depth using the water-based mud.
The second casing will be for ~1800 m depth using low toxicity synthetic oil-based mud (for faster completion & considering hard geological structures).
The third casing will be for depth > 1800 m to formation zone, say around 2400 m depth using SBM.
The duration of the well drilling and completion is 45 – 60 days/ well.
The well testing (for the 30 to 60 days/well. PRODUCT AND WELL DESIGN DETAILS<br>
slide8. 8 SELECTION OF LAND FOR SETTING UP WELL PAD Initially 300 m X 300 m (9 hectares) would be taken on temporary lease basis for the construction of well pad (drill site) for drilling of the wells.
If any land site is sensitive/human settlement is there etc., those areas will be avoided and nearby lands suitable to the operation can be leased out
Based on successful oil & gas discovery, permanent land possession is required.
Maximum 10 well pads will be in operation at Kaza block i.e., 90 hectares land required in small parcels at various locations within Kaza block area.
The 30m width access roads will be required to connect the well pads, laying pipeline, overhead line and other utilities. This road will be acquired in the combination of permanent possession and RoU (Right of Usage).
The existing roads will be strengthened by Cairn, if used for heavy vehicular movements.
Land lease amount and related compensation will be paid based on Government approved rates, in consultation with both District Authorities and the Landowners.
The return of the land after the lease period will be handed over after proper restoration of the land.
The restoration will include complete cleanup of the land, restoring by improving the fertility of the soil, ensuring no contamination to the soil, ground water etc., and the hydrocarbon wells shall be plugged and abandon as per OISD standards.<br>

Study area: 902.46 Sq.km., Primary survey has been conducted up to 5 km surrounding the studied well
Sampling location for primary data: Chataripalem, S N Gollapalem, Lellagaruvu, Nimmakuru, Nidumolu, Chitturu, Tummalapalem, Tarakaturu, Maklavaripalem, Kaza, Guduru, Palankipadu
Total 37 species of trees belong to 17 families, total 7 species of shrub belong to 6 families, total 11 species of herbs belong to 9 families have been identified during the survey.
There was no endemic and threatened plant species was observed in the study region during the survey. There is no declared sanctuary park and reserve forest in the study region. In case of Avi fauna only schedule IV species have been recorded from the study region and in case of reptile schedule II species like cobra has been observed.
No protected/threatened fauna was cited during the survey.<br>
slide31. 31 SOCIO-ECONOMIC STATUS Socio-Economic Environment:
During the primary survey it was observed that almost proper road facility is available in all villages within 10 km radius.
Literacy rate of the study region is between 58.45 to 84.43%. On the basis of survey for literacy rate data, it is interpreted that there is need to promote more and higher education to cover larger people.
Almost, all the villages have more than 50 % people as non-workers/having continuous job availability. It indicates that the problem of unemployment can be solved by providing proper skill-based training and education.
There is also need, to establish more industries in and around the area, so that employment opportunities can be increased. Basic amenities like Education facilities Health care facilities, water supply, electric power supply, mode of transportation etc., are available in all villages.<br>
slide32. 32 BASELINE ENVIRONMENT DETAILS: RISK STUDIES & DISASTER MANAGEMENT Major incidents:
A fire, explosion due to release of a dangerous substance like flammable fluid or natural gas resulting from a work activity which could result in death or serious personal injury to people within the area of activity;
Hazards associated include uncontrolled release (liquid and gas) and subsequent fire due to accidental loss of containment.
Major Hazards:
Typically, the potential major hazardous incidents arising from the proposed project and its associated supporting facilities are mainly related to the leaks and rupture of hazardous liquids and gases processed in equipment, stored in tanks and transported through pipelines.
Mitigation Measures:
Drilling will be carried out using Blow Out Preventor (BOP) installation
Risk will be mitigated through having operational control system and procedures including the risk mitigation measures such as auto shutdown, fire & gas detector, fire control measures etc.
SCADA/DCS, will be provided across pipeline length for effective monitoring. Leak detection system (LDS)/ Pipeline Intrusion Detection (PIDS) will be installed in pipeline ROU.<br>
slide33. 33 BOPs are used to shut in and control the well in the event of gas or oil being encountered at pressures higher column of mud in the hole.
BOPs typically consist of 3 ram preventers and are hydraulically operated with a second remote control panel.
In the event of the high-pressure kick with the drill string in the hole, the BOP is closed around the drill pipe and the mud is circulated down the drill string and back to the mud tanks through the choke line and back pressure manifold.
If a kick or blow out occurs with the drill string out of the hole, the blind rams are closed, and heavy mud is pumped into the well through the kill line. Any gas can be bled off through the choke line.<br>
slide34. 34 CONSEQUENCE ANALYSIS Detailed Consequence analysis has been carried out considering different scenario, which is as under: Pool Fire Consequence Contour for Diesel Tank (100mm)<br>
