CNOOC’s Kenli project starts production

CNOOC has brought online its shallow water Kenli 6-1 oilfield 5-1, 5-2, 6-1 block development project in the Bohai Sea.

Located in about 19 m water depth, the main production facilities include a central platform and six unmanned wellhead platforms. CNOOC plans 107 development wells, including 67 production wells, 36 water injection wells and 4 water source wells. The operator expects the project to reach peak production of 36,100 bbl/d in 2024.

Kenli 6-1 oil field 5-1, 5-2, 6-1 block is the main area of Kenli 6-1 oil field, which is the first large-scale shallow lithological oilfield with a reserve of 100 million tons discovered in Laibei lower uplift in the Bohai Sea. The project represents the company’s first large-scale use of standardized unmanned platforms in the Bohai Sea.

CNOOC Ltd operates the project and holds 100% interest in it.

In related news, CNOOC announced the Bozhong- Kenli oil fields onshore power project had started operations. The project will supply electricity to 39 offshore production platforms in the Kenli oilfields, Bozhong 19-6 condensate gas fields and Bozhong 28-34 oil fields. By 2025, the project is expected to support the production of about 400,000 bbl/d in the region.

Barents Sea find may tie back to Goliat

Vår Energi’s latest Barents Sea wildcat has found gas offshore Norway.

The 7122/9-1 T2 well, referred to as Lupa, is the first exploration well drilled in PL 229E. It is located about 27 km northeast of the Goliat field, which is also operated by Vår Energi. According to the Norwegian Petroleum Directorate (NPD), the licensees will consider tying the discovery back to existing infrastructure on the Goliat field at a later date.

The Transocean Enabler drilled the well in 403 m of water depth.

The objective of the well was to prove petroleum in lower Triassic reservoir rocks in the Havert Formation, as well as to investigate the reservoir quality in the Ørret Formation in the Upper Permian, according to the NPD.

The well encountered a 55-m gas column in the targeted sandstones of the Havert formation of Triassic age. Extensive data acquisition and sampling have been carried out, but the well was not formation tested, the NPD said.

Vår Energi operates the production license with a 50% stake on behalf of partner Aker BP, which holds the remaining 50% interest. Eni holds 63% share in Vår Energi.

Petrobras has wrapped up the sale of its stake in the Papa Terra Field offshore Brazil to 3R Petroleum Offshore.

Discovered in 2003, the Papa Terra Field in 1,200 m water depth is part of the BC-20 concession. Production at Papa Terra started in 2013. Average oil production from September to November 2022 was 16,200 bbl/d through the P-61 tension leg wellhead platform and P-63 FPSO, where all the production is processed. The P-61 and P-63 have a processing capacity of 140,000 bbl/d of oil, injection capacity of 340,000 bbl/d of water, storage capacity of 1.4 MMbbl and slots to connect up to 21 production wells and 11 injection wells.

According to ANP data, the estimated original volume of oil and gas in place is approximately 2 Bboe, with a density between 12° and 16° API and low level of contaminants. The current recovered fraction is around 2%, while the Campos Basin average is around 16%, 3R Offshore said.

Petrobras originally announced that it would sell its Papa Terra stake in July 2021, and 3R Offshore paid an initial $6 million when the contract was signed. On Dec. 22, National Agency of Petroleum, Natural Gas and Biofuels (“ANP”) approved the transfer of 62.5% stake in Papa Terra to 3R Offshore.

Now, 3R Offshore has paid Petrobras $18.2 million, and Petrobras said it expects to receive up to $80.4 million in contingent payments, depending on future Brent prices and asset development.

3R Offshore has now assumed operatorship of the field and holds 62.5% stake. Partner Nova Técnica Energy Ltda. holds the remaining 37.5%.

3R Offshore said the acquisition of Papa Terra Cluster represents an important milestone for the company's offshore portfolio, with the beginning of its operations in deep waters and the start of operations in the Campos Basin.

The asset's reserve certification, issued by DeGolyer and MacNaughton with a base date of Dec. 31, 2021, indicates a volume of proved plus probable (2P) reserves of 172.0 MMboe for 100 % of the asset. The company has a net interest of 53.13%[1] of the asset, which represents 91.4 million boe in 2P reserves.

The Cluster recorded an average daily production of 15,100 boe in 2021, with peak daily production reaching 19,900 boe in August of the same year. The average production for 2021 was impacted by the maintenance shutdown carried out by the operator since December 2021 for repairs and improvements in some FPSO systems. In August 2022, operations in the Papa Terra field were resumed with average daily production of around 16,000 bbl of oil, supported by three producing wells (PPT-50, PPT-51 and PPT-16). The asset has also two more closed production wells (PPT-17 and PPT-37), which should be reopened after adjustments to the processing and storage systems, which will be carried out in the first months of operation by 3R. It should be noted that all of Papa Terra's production systems have the capacity to support the implementation of the development plan projected for the asset, together with revitalization and redevelopment activities, which are 3R's core business.

Sinopec updates on Fuling output

Sinopec announced that China's Fuling shale gas field, the first commercially developed shale gas field in the country, has produced 53.2 Bcm of shale gas over the past decade.

The output is a production record for shale gas fields in China, according to Sinopec.

The company’s Jiaoye 1 HF well, located in Fuling, southwest China's Chongqing Province, started production at the end of 2012, and the field holds nearly 900 Bcm of proven reserves, Sinopec said.

The operator said it has been accelerating its exploration and development of shale gas in the Sichuan Basin in southwest China based on its Fuling experience. Sinopec’s four shale gas fields—Fuling, Weirong, Yongchuan and Qijiang—hold proven shale gas reserves of 1.19 Tcm, according to the company.

Sinopec sets Sichuan Basin depth record

Sinopec said it had drilled its Yuanshen-1 exploration well in the Sichuan Basin to a basin record vertical depth of 8,866 m.

According to Sinopec, the well shows the potential of deep ancient carbonate rocks in the region. The ultra-deep carbonate rock in the Dengying Formation showed positive hydrocarbon evidence in the porous reservoir, the operator said.

The well was part of Sinopec’s "Project Deep Earth – Natural Gas Base in Sichuan and Chongqing" effort, which it is carrying out in collaboration with Sinopec Exploration Co., Sinopec Southwest Oil & Gas Co., Sinopec Zhongyuan Oilfield Co., Sinopec Jianghan Oilfield Co. and Sinopec East China Oil & Gas Co.

The company said it has developed a handful of technologies to support ultra-deep drilling.
