BG to award Tapti development jobs in November

Vol 9, PW 13 (06 Oct 05) Exploration & Production

British Gas is set to award engineering, procurement, installation and construction contracts to boost gas production from the Tapti gasfield, where it is joint operator with Reliance and ONGC.

The consortium is evaluating the bids, we learn. Contracts will most likely be awarded by November.

Already approved is a CAPEX budget of approximately $450m to implement the Tapti development plan, which will see the installation of one processing and one wellhead platform in about 30 metres water depth. Also envisaged is a 20-inch diameter, 89-km long pipeline to transport the gas to ONGCs receiving station at Hazira from where the gas will be fed into GAILs HBJ pipeline.

Up to 12.5m cm/d gas will pass through the processing platform. Plans are to drill eight new development wells from the wellhead platform.

Each well will be drilled to between 1800 and 2000 metres depth, we are told. Since the sands are loose, gravel packing will be needed.

Consortium sources tell us the development plan at Tapti is designed to boost gas production from the present 6.8m cm/d to up to 12.5m cm/d by 2007. Most of the development programme is aimed at the mid-Tapti field.

By November, the consortium hopes to have completed its 18-well infill programme at Tapti. After that the consortium will focus on a five-well exploration programme.

One well has already been drilled and four more have to be drilled. Nearby, the Panna oilfield is also set to see a lot of activity when two new wellhead platforms will be installed: PH and PJ.

Consortium sources confirm plans to drill a total of 20 wells (11 firm and nine contingent) to yield an additional 18m barrels of oil. In total, the Panna, Mukta and Tapti oil and gasfields produce 35,000 b/d.

Hopes are alive that this will rise to 55,000 b/d by 2007-08. Every month two new wells are being drilled, we hear.
