Hammerhead, drill selection & costs5 Dec 2018 17:56
As we thought, ECO are highly likely to already have a discovery in Hammerhead as it goes into Orinduik, so no need to drill a well there, which the following Upstream article talks about...
“We consider Hammerhead in many ways to extend into our block, meaning that Hammerhead is a discovery also on our block,” Holzman said.
“We believe that it will be some time in the near to mid-term future subject to unitisation talks and we (will) try to start those talks based on the geophysics, which are very clear to all parties, instead of spending some $40 million on a well that basically nobody needs to drill.”
Holzman said the partners may be in a position in January or February to nominate the second well on Orinduik, although he agreed it is most likely they would drill on Aurituk next, with both wells possibly drilled back-to-back.
“I think eventually this block can easily be a target for 10 or more wells,” he said.
Eco, which is a 15% stakeholder in Orinduik, has put the estimated net cost to it of the first well at $7.6 million, although Holzman cautioned that the company was being conservative on the high side with that estimate.
With Tullow on 60% and Total on 25%, this would assume a gross well cost of $50 million, which would be very high considering current drillship dayrates.
However, Holzman explained: “Because it is the first well, we are probably going to put some extra casing, etc, just to be on the safe side.”He also said the cost assumes a duration of 43 days to drill the well, whereas ExxonMobil in reality is drilling its wells on Stabroek in 20 days or less, he added.
“There are two candidates at the moment, both with the same daily rates, both confirmed that they can drill in our timeframe,” Holzman said of an impending rig charter, without identifying the finalists.
