Jun 30: Details of the drilling operations are as follows:
8Well(s) will be drilled using a mobile drilling rig of capacity of around 1000 HP for development drilling and 1500 – 2000 HP for exploratory drilling, equipped with rotary drive system.
8Production testing for developmental wells is 3-5 days whereas for exploratory wells it is 30 days.
8Proposed drilling fluid for both wells is same, Water-based Mud System.
8Anticipated Volume of Drill Cutting for each Well is 100- 200m3.
8Water Requirement for each well is 50 KLD.
8Well Depth for developmental wells is 600-1600 m, and for exploratory wells is 3000-4500 m.

8The estimated drilling period of each well is about 35-75 days depending upon the drill depth.

Kharsang Oil Field-I: Increasing production by 4 times

 

GeoEnpro, plans to go ahead with a 720 crore project of  Development and  Exploratory Drilling project in Kharsang Oil Field at Arunachal Pradesh.

8At present, total well count at Kharsang Oil Field is 70 wells, the crude oil production is around 1000 BOPD and gas production is around 50,000 m3/day.
8It plans to increase its production of crude oil by approximately 4 times to 4000 BOPD
8The Kharsang Oil Field (KOF) comprises of Oil India Limited (OIL) (40%), Geopetrol International Inc (25%), Jubilant Energy India Pvt. Ltd. (25%) and GeoEnpro Petroleum Ltd. (12.5).
8It has proposed to Development Drilling of Forty (40) wells and Exploratory Drilling of five(05) wells.

Kharsang Oil Field-II: Details of Development and Exploratory wells

All 45 wells (40 development and 5 exploratory/appraisal) shall be taken up for drilling under different drilling campaigns in a phase-wise manner.
8Out of 45, sites of 27 drilling wells are located for which Forest Clearance has already been applied .
8The remaining 18 wells shall also be drilled from the identified locations, depending upon the production testing results of the 27 wells and additional studies planned to be carried out in the future to target deeper prospects.
8Changes in exact drilling locations and programme are always likely based on the findings of additional reservoir studies, development drilling.
8The estimated drilling period of each well is about 35-75 days depending upon the drill depth.

Kharsang Oil Field-III: Power Consumption and Fuel requirements

At present, KOF is equipped with 4 gas fired gensets (1x 500 KVA, 1 x 450 KVA and 2 x 180 KVA) and one diesel fired genset (1 x 170 KVA).
8The power requirements during the site preparation and construction phase will be met by DG Sets.
8For Proposed drilling of development wells, power source of two 500 HP Diesel Engines to be used, each Engine running for 12 hrs per day. For auxiliary power, two 320-500 KVA gensets would be required. Diesel requirement would be around 4-6 KLPD.
8ForProposed drilling exploratory wells, four 1900 HP engine (3 Operating + 1 Standby) will be the power source. For auxiliary power there would be four 1750 KVA gensets. Around 10-12 KLPD of HSD will be fuel requirement.

Kharsang Oil Field-IV: Oil storage and Loading details

The crude oil being produced from the wells flows through a 4� pipe line to the existing Oil Collecting Station (OCS) where it is treated to separate oil, water and gas but for wells of low pressure, fluid is diverted to group tanks (GT) through 2� nom bore pipe lines and then to OCS.
8For the proposed drilling activity at Kharsang Oil Field in a phased manner, additional pipeline to connect the producing wells to OCS shall be laid.
8Processed crude oil is finally stored in the Custody Transfer Tank Farm before dispatch to the refinery.
8There are 8 nos. of fixed roof tanks each having storage capacity of 795 Kls.
