Cairn India to Drill More Exploratory and Appraisal Wells in Rajasthan

---

Researched by Industrial Info Resources India (Delhi, India)--Cairn India Limited (CIL) (BSE: 532792) (Gurgaon, India) is set to undertake another round of drilling at ''RJ-ON-90/1'' block in Rajasthan. The onshore block covering an area of 3,111 square kilometers lies in the Barmer and Jalore districts of Rajasthan. The hydrocarbon block was awarded to a joint venture of CIL and ONGC Limited (ONGC) (BSE: 500312) (Dehradun, Uttarakhand) in 1995 with Cairn India as operator of the block.

Cairn India intends to drill more than 300 exploratory and appraisal wells in this region. The hydrocarbon rich block has already been subjected to drilling of more than 450 wells. A total of 25 discoveries have been made so far, out of which six wells are likely to begin production.

According to Cairn India, the depth of these wells is expected to vary from 1,100 meters to 6,000 meters. Water-based mud will be used for drilling in the initial sections of each well, while synthetic-oil based mud has been proposed to be used for drilling through deeper sections.

The exploratory work would involve site preparation, well foundation, rig building, drilling as well as restoration of the well site. Two Diesel Generator (DG) sets of 1,200 kilovolt ampere (kVA) each will be installed to meet the power requirement for the drilling project. Fresh water requirement for the project has been pegged at 70 cubic meters per day (m3/day), which will be transported to the site through tankers. The total wastewater generation has been estimated to be around 20m3/day.

Cairn India is one of the largest oil and gas exploration and production companies in India with a market capitalization of $ 10 billion and operates more than 25% of India's domestic crude oil production. Cairn India has a portfolio of nine blocks- one block in Rajasthan, which contains multiple assets, two on the west coast and four on the east coast of India and one each in Sri Lanka and South Africa.
