In well D-1 the production test was carried out over a period of 3 days. D-1 produced significantly more oil during the flow test, compared to first well D-2 test results announced on 24February 2020.
By keeping the tubing head pressure above 1100 psi, the well was flowing at 48/64 in. choke with a peak of 6048 bbl with 5.7 million ft3/d, which in terms boe/d is 6998 bbl.
Even by opening the choke to 52/64 in., the tubing head pressure is being maintained in excess of 1100 psi with a peak flow of 6306 bbl and 6.5 million ft3/d, which is 7389 boe/d.
The two wells drilled and completed in the block B-80 have surpassed expectations and the average production of oil and gas in oil equivalent terms should exceed 8000 bpd.
Additionally, in the D1 well, a new discovery was made in the Deccan Trap formation of a 6 m interval, which is potentially hydrocarbon-bearing as seen from the mud gas and logs. This interval can potentially produce oil and gas which needs to be tested. This discovery will be further appraised in the next well drilling and would add value to the block.
P. Elango, Managing Director, said: “Having secured the two subsea wells ready to flow, our next task is to optimise the total cost of evacuation of oil and to reduce the break-even price (BEP) further down from our earlier guided level of US$35/bbl with appropriate return to the investment. Industry has sought series of fiscal relief from Government of India to protect the domestic upstream oil and gas sector.
We plan to leverage the low price environment in oilfield services sector to bring down the overall costs. We are determined to continue the momentum and complete the project to deliver the first oil and gas from both the wells as and when the current situation improves. Our endeavour is to appraise the new discovery in Deccan trap formation to increase the value of the block potential in the subsequent drilling programme.
Overall, our plan is to remain focused on what we can control, which are costs and volumes, and make each of our operating assets profitable through our proven low cost and fast track operating model in this volatile price and uncertain environment.”
