ONGC drills dry well at frontier Palar block

Vol 18, PW 2 (11 Sep 14) News in Brief

ONGC’s first exploration well NAAA in the frontier Palar basin has disappointed.

But it is now hoping for better luck at the second well NAAB, spud on August 25 at its PR-ONN-2005/1 onland block, around 55-km from Chennai, using its own 2000-hp land rig. ONGC will target Cretaceous era Gondwana sands and expects to take over two months to drill to 2900 metres TD.

"We’ll drill till basement or below basement," says a company source. ONGC completed the first well NAAA, seven-km away, on August 17.

"Results weren't encouraging," we hear. "The well has been plugged but not abandoned.

We’re analysing logs.” ONGC (80%) operates the 1807-sq km block with Tata Petrodyne (20%).

Separately, Cairn India plans to begin exploratory drilling at adjacent offshore block PR-OSN-2004/1 by end-2015. Cairn (35%) operates the 9417-sq km block, which holds up to 30m barrels of oil, with ONGC (35%) and Tata Petrodyne (30%).
