Selan Energy begins four well programme at Bakrol

Vol 9, PW 20 (26 Jan 06) Exploration & Production

Selan Energy is carrying out a four-well appraisal and development programme at its discovered Bakrol field onland Gujarat.

Selan has hired a rig from Dewanchand Ramsaran for the drilling programme and has already drilled two wells. PETROWATCH learns the first well was spud on 14th December, 1-km south west of existing producer Bakrol-5 and that target depth of 1500 metres to the Kalol formation was reached without any mishap around 30th December after fifteen days.

We hear a 5.5-inch production casing was lowered and that logging results have indicated hydrocarbons. The reservoir development was not found to be very encouraging but Selan plans to test two zones between 1400 metres and 1470 metres, we hear.

After drilling this well (P-3) the rig was released and moved to the next location: P-4. Selan has hired a John Energy workover rig to carry out testing.

The rig is moving on to location. Selan spud P-4 on 5th January and reached target depth of 1550 metres, also to the Kalol formation, around 20th January.

Logging results here were more encouraging than at P-3. Well P-4 is 700 metres south east of producing well Bakrol-2.

Selan plans to test this well also using the John Energy workover rig. If all goes well, Selan should complete its drilling programme by the end of February or early March.

Some time back, Selan drilled a dry hole at location A-3, about 400 metres north of Bakrol-5. The 35-sq km Bakrol field is with Selan since 1995.

Previous owner ONGC drilled seven wells of which four were abandoned and three were completed as oil producers. Bakrol-1, 2 and 3 yielded crude only for a short time because a high water cut intervened forcing ONGC to suspend production.

But thanks to some intelligent interpretation of ONGC well data Selan resumed production from 1995. Bakrol-2 and 5 together produce about 100 b/d.
