CHAPTER - 2 INTRODUCTION OF THE PROJECT / BACKGROUND INFORMATION 2.1 Identification of project and project proponent The Kharsang Oil Field (KOF) is located in the state of Arunachal Pradesh, about 50 Km east of Digboi Refinery and is part of the Assam-Arakan Basin. The field was discovered in 1975 by M/s Oil India Ltd. (OIL) and was put into regular production in 1983. Oil India drilled a total of 36 wells till 1995 and the total production was around 265 Barrels of Oil per day (BOPD) as of 1995. In 1995, for further development of the field, Government of India (GOI) awarded the Kharsang Oil Field to a Consortium comprising of the following partners under a Production Sharing Contract (PSC) dated 16th June, 1995, Consortium Members Participating Interest (PI) • GeoEnpro Petroleum Limited (Operator) 10% • Enpro India Limited (Presently Jubilant Energy) 25% • Geopetrol International Inc. & 25% • Oil India Limited 40% The GOI entered into twenty-five years PSC with the consortium, with an extension provision of further 10 years. GeoEnpro was designated as the Operator of the Kharsang Oil Field. KOF has a total Mining Lease area of 11 Sq.Km. and is rectangular in shape admeasuring nearly 3.8 Km in E- W direction and 2.9 Km in N-S direction. Petroleum Mining Lease (PML) was executed between Government of Arunachal Pradesh (GoAP) & JV Consortium on 21.10.1997 effective from 16.06.1995 for a period of 20 years. As part of its offer to further develop and enhance the production from the Field, the consortium had agreed to drill additional development wells. In 1996, GeoEnpro had engaged National Environmental Engineering Research Institute (NEERI) to carry out Environmental Impact Assessment (EIA) study for carrying out work-over operations in the existing 36 wells and for drilling of 10 new development wells for enhancing oil and gas production from the KOF. The same was submitted to Government of Arunachal Pradesh (GoAP) for obtaining No Objection Certificate (NOC). Arunachal Pradesh State Pollution Control Board (APSPCB) after conducting the public hearing granted the No Objection Certificate (NOC) vide letter no. FOR.141/CONS/91/P-II dated 09/11/1998. Subsequently, the consortium applied for Environmental Clearance (EC) on March 15, 1999 to MOEF for carrying out the drilling of 5 development wells and workover operations. MOEF vide its letter dated September 15, 1999, informed the consortium that considering that the total cost of the project is less than threshold limit (Rs. 50 Crore), the proposed drilling operations and work over activity project does not fall under preview of EIA notification and hence the Environmental Clearance is not required under EIA notification of 1994. Accordingly, GeoEnpro drilled 5 development wells during the period February 2005 to December 2005. To further augment the oil and gas production from the field, the consortium had applied for Environmental Clearance (EC), as per EIA Notification 2006, on November 01, 2006 to MOEF for carrying out drilling of 40 development wells. MOEF vide letter no. F.No. J-11011 /389/2006-IA II (I), dated November 15, 2007 granted the EC for drilling of 40 wells. After obtaining the EC in 2007, the consortium has drilled 29 development wells till date, under different drilling phases, at the Kharsang Oil Field out of the 40 wells for which EC was granted. At present, total well count at Kharsang Oil Field is 70 wells and present crude oil production is around 1500 BOPD. The quantity of crude oil produced from the field is dispatched to Digboi refinery of Indian Oil Corporation Ltd.
