Premier faces delay to drilling in Assam

Vol 9, PW 5 (16 Jun 05) News in Brief

Premier Oil is facing a months delay to its drilling schedule at its exploration well in AAP-ON-94/1.

Target depth of 4200 metres is now likely to be reached by the end of June. Drilling began on 1st April and had reached 3400 metres early June.

Mud loss at the 26-inch hole at about 700 metres is blamed for the delay. A fishing problem was also reported in early June.

After the fish was recovered and another 100 metres drilled, Premier lowered the 9 5/8-inch casing. Premier wants to drill to the Tipam and Barail formations and complete the well with a 7-inch liner.

No hydrocarbon shows have yet been made but Premier is hopeful because Oil India is producing gas from the adjacent Kusijan field from 3900 metres depth. Premier is in Phase-II of the exploration period, which ends in November, and commits it to drill one well.

Premier holds 38% of the 652-sq km block AAP-ON-94/1. Oil India holds 10%, HOEC holds 25% and Indian Oil holds 27%.
