Deepsea Matdrill strikes gas

Vol 20, PW 18 (01 Jun 17) News in Brief

Jagson's mat-supported jack-up Deepsea Matdrill has silenced doubters by successfully completing a gas and condensate discovery well at ONGC's 80-sq km pre-NELP eastern offshore GS-15/23 permit near the Vashishta and S1 fields.

ONGC is now production testing well GS-15#AR, drilled to 4110 metres in water depths of 36.4-metres. Matdrill, which some industry sources have criticised as 'underperforming,' spud the well on February 2 and completed it in good time by April 11, 2017.

"We have been testing the well since then," confirms an ONGC source. "Right now we are testing Object-4 (of interest)." By May 30, the well was flowing gas and condensate from a four-metre interval between 3650 and 3654 metres.

"There was a pressure build up in the well," we hear. "But now it is under control." An ONGC source says it is happy with the rig's performance as it has completed one year without significant downtime.

"Before this the rig drilled its last well, also on the east coast, to 2500 metres TD in one month," he says. "That well wasn't tested."
