CNOOC hits light crude in Bohai Sea
CNOOC Ltd. reported on March 1 its Bozhong 26-6 discovery in the Bohai Sea holds 100 million tons (MMton) of reserves.
Located in 22 m water depth, the discovery well encountered 321 m of oil pay. During the well test, the Bozhong 26-2-2 discovery well produced an average of 2,040 bbl/d of light crude and 11.45 MMcf/d of natural gas.
"Bozhong 26-6 oilfield is the third oilfield discovery with hundred million tons of reserves in southern Bohai Sea after Kenli 6-1 and Kenli 10-2. It is identified as the largest metamorphic buried hill oilfield in China,” Xu Changgui, deputy chief exploration engineer at CNOOC, said in a press release.
Vår Energi’s Barents Sea wildcat
Vår Energi ASA’s 7122/8-1 S wildcat well near the Goliat Field in the Barents Sea encountered about 240 m of gas and oil columns, the Norwegian Petroleum Directorate reported on March 2.
The Transocean Enabler drilled the Countach well in 399 m water depth in Vår-operated PL229. The well, which has been permanently plugged and abandoned, was not formation-tested, but extensive data acquisition and sampling were carried out.
Vår said preliminary estimates of recoverable reserves are between 3 MMboe and 13 MMboe but that the potential of the Countach prospects is estimated at up to 23 MMboe of recoverable oil.
“We will consider potential commercial development options and tie-in of the discovery to Goliat FPSO,” Rune Oldervoll, Vår Energi’s executive vice president for exploration and production, said in a press release. “Due to late arrival of the drilling rig on the field this winter, we have not been able to carry out the planned sidetrack before the environmental drilling restrictions commence on 1 March. We look forward to continuing to explore the area around Goliat at a later point in time.”
Vår Energi operates the license with 65% interest on behalf of partner Equinor with 35%.
Papa Terra production halted
3R Petroleum Oil and Gas reported on Feb. 28 that production had halted at the Papa Terra Cluster offshore Brazil as of Feb. 25, due to limitations in the energy generation and supply system of the tension leg wellhead platform at Papa Terra.
The company said repairs were expected to be complete within a week and that production would then gradually resume. Before the stoppage, four wells were producing an average of close to 17,000 bbl/d.
Contracts and company news
Suriname bid round webinar next week
Bids are due in Suriname’s Demerara Bid Round (DBR) on May 31, bid round advisor Envoi said on March 1.
The bid round opened on Nov. 8, and a webinar on the prospectivity of the acreage is set for March 8 at 13:00 GMT (London).
The acreage on offer comprises six blocks covering an area of 43,956 sq km over the sparsely explored Demerara High. Staatsolie and specialist independent consultancies carried out studies over the acreate in 2022 that demonstrate significant undrilled prospectivity throughout the Upper and Lower Cretaceous and the Jurassic. These intervals thicken under the Demerara area and are clearly analogous to the proven conjugate margin plays in West Africa. More information about the bid round and webinar are available here. New participants must register to bid by April 28.
