Oil India is preparing to begin drilling two more High Pressure/High Temperature wells at its promising KG onland block KG-ONN-2004/1, possibly by June this year (2017).

Oil India has identified two locations: 6 and 10. At location 10 in Puducherry's Yanam district Oil India will drill the well to 5000 metres TD using a heavy-duty 3000-hp rig from US-based Nabors Drilling.

No details of drilling plans at location 6 are yet available. At present the Nabors rig is drilling HP/HT well YLK-1 at Yedurlanka village in Andhra Pradesh's east Godavari district, within the same block.

Oil India has managed to bring under control severe mud loss between 1000 and 1500 metres. "We have put additional casings in the well to deal with mud loss," says an Oil India source.

Oil India has also used a fifth stage 11 ¾-inch casing from 1550 metres to 3250 metres. By March 29 the drill-bit had reached 3260 metres of the planned 5200 metres TD.

"It will take another 50 days to complete the well," adds our source. "After drilling this well the rig will move to location 10." Separately, Essar rig LR-3 spud appraisal well DNG-A1 on March 7 at the same block to appraise the Dangeru-1 discovery which flowed 13,000-20,000 cm/d from four zones during testing between October and December 2014.

By March 29 the drill-bit had reached 994 metres.
