Selan plans more development at five onland fields

Vol 12, PW 9 (18 Sep 08) Exploration & Production

Gurgaon-based Selan Exploration is planning a 10-well development drilling campaign at its five-onland oilfields in Gujarat beginning late October or early November.

PETROWATCH learns oil output from the Bakrol, Indrora, Lohar, Ognaj and Karjisan oilfields operated by Selan reached 1200 to 1400 b/d this month (September) compared to 320 b/d up until July 2008. “Oil production has gone up as a result of our eight-well development drilling programme begun in April and completed in July,â€‌ said an industry source.

Those eight wells were a combination of development and workover wells. Selan hopes to further double current production to around 2800 b/d from the five fields around six months after the campaign starts.

Selan is planning to use a 1500-hp rig from Indian drilling contractor Dewanchand Ramsaran, which will be mobilised to location by the middle of next month once it has completed a nearby drilling assignment for GSPC. Selan also wants to acquire 3D seismic at all the five blocks.

“Bids submitted by seismic contractors are being evaluated right now,â€‌ we hear. “It will be finalised soon.

â€‌ Development drilling and seismic acquisition will take place side by side. Seismic acquisition, we are told, could take up to three months.

“Mobilisation of equipment and crew (to acquire seismic) can take time,â€‌ adds our source. “Drilling cannot be put on hold and we have already identified drilling locations for the 10 development wells.

â€‌ For the drilling programme completed in July, Selan had hired one rig from KST Drilling of Malaysia at $18,500/day. “Later we hired one more rig from Dewanchand to speed up the (drilling) programme.

â€‌ Those two rigs were demobilised from the site after the campaign ended in July. Set up in 1985, Selan entered the oil exploration business in 1992 when it was awarded the marginal Bakrol, Indrora, Lohar, Ognaj and Karjisan oilfields the same year.

Bakrol measures 36-sq km, Indrora measures 120-sq km, Lohar and Karjisan both measure 5-sq km and Ognaj measures 14-sq km.
