ONGC drilling at 2 exp. wells on track
Despite the strict lockdown, ONGC explorers are confident drilling can continue at two critical exploration wells in Assam.
With only a skeleton staff on location, ONGC confirms that its Silchar-based AAFB exploratory asset will complete drilling at location BPAA inside the 703.61-sq km Cachar District PML by April 10. "The local administration permits only two vehicles at any given time," he says.
"But we have organised ourselves in such a way to ensure operations keep to the schedule." By April 7, ONGC company-owned rig E-1400-12 had drilled location BPAA to 1050 metres.
Spud on March 11, ONGC is aiming to reach 1347 metres final TD to test up-thrust Renji, lower Bhuban and sub-thrust upper Bhuban prospects. "But no testing can take place because there is no manpower," he adds.
"Our biggest challenge will be dismantling the rig before May 14." Located near a river, ONGC will struggle to dismantle the rig before water levels rise during monsoon rains.
ONGC also reports good drilling progress with well WH-1, likewise in the Cachar District PML, at location WHRAA. By April 6, 'kelly' rig E-1400-11 had reached 2719 metres depth at WH-1, still short of final TD of 4152 metres.
