Greka rig to reach Bokaro for ONGC in October

Vol 20, PW 26 (21 Sep 17) Exploration & Production

Greka Drilling is preparing to mobilise to BK-CBM-2001/1 at Bokaro in Jharkhand to begin its 73-well CBM drilling contract for ONGC.

"Next month (October) the rig should reach," reports a source. "ONGC gave Greka 120 days in the LoA, one or two weeks either way makes no difference." Still unclear is which rig Greka will mobilise: GD75-16, GD75-18 or GD75-20 sitting in a SEZ near Kolkata port? Or one of two rigs (GD75-17, GD75-19) at Durgapur on standby for possible re-deployment by Essar? "All five are identical (Drillmec-made CBM-only) rigs," we hear.

"Makes little difference which one is used." At Bokaro, Greka is preparing to sign a lease for a project office housing up to 60 staff, including rig crew. "This is essential for day-to-day coordination with ONGC," we hear.

When drilling Greka believes it can easily complete a minimum two wells a month, each to between 500 and 1500 metres. "If drilled to 500 metres it should take two-three days or if drilled to 1500 metres around six-nine days," adds our source.

"Each of the Essar wells was drilled to between 1000-1500 metres and took around eight-nine days." After weeks of suspense, ONGC issued a LoA to Greka on June 14 and two days later London-listed Greka confirmed the estimated $15m award, "subject to contract and the issue of a performance bond."
