Adani Welspun sets March target for Gujarat well

Vol 13, PW 16 (28 Jan 10) Exploration & Production

Ahmedabad-based Adani Welspun (90%) and Ukraine-based Naftogaz (10%) hope to begin exploratory drilling at their Gujarat onshore block CB-ONN-2004/5 by March.

PETROWATCH learns the consortium is in the process of hiring a rig to drill three of nine exploration wells committed at this 75-sq km NELP-VI Cambay basin block in Phase-I. “We cannot disclose the name of the drilling contractor now,â€‌ says a consortium source.

“It will be finalised soon.â€‌ Once drilling begins, the first three wells should take five to six months.

Adani and Naftogaz, we hear, want to hire a 1500-hp rig that can drill up to 4000 metres or to basement at CB-ONN-2004/5. But other industry sources tell us that Adani Welspun has already bought its own 2000-hp rig for the job.

“This rig is being made by LeTourneau,â€‌ says an industry source, “at a yard in Houston.â€‌ Our source adds that the consortium has identified three drilling locations from interpretation of 90-lkm 2D and 90-sq km 3D shot by Hyderabad-based Alpha Geo back in 2008.

According to an industry source, the consortium has finalised most of the associated tenders for its planned exploratory programme, such as cementing and logging. One service contractor, who asks to remain unnamed, tells us he has submitted an EoI for well testing.

Separately, Adani and Naftogaz are also planning to begin Phase-I exploratory drilling at their 95-sq km onshore AA-ONN-2004/4 block in Assam by September. Alpha Geo is acquiring 175-sq km 3D at this NELP-VI block, which lies near the producing Kharsang oil and gasfield operated by GeoEnpro, a joint venture between Jubilant Energy and Geopetrol.

“Seismic should be completed by March,â€‌ says an industry source. “Processing and interpretation should be done in the next six months.

â€‌ Our source says the consortium has identified locations for two of the five committed wells and will need a 1500-hp rig. “Wells will be drilled up to 4000 metres,â€‌ says this source.

“We will decide which geological formation to target closer to drilling.â€‌
