據鉆機地帶4月13日消息稱，挪威石油理事會(NPD)周四透露，Aker BP在北海通過生產許可證第919號的25/4-15口初探井發現了石油。

NPD強調，該井的目標是在Heimdal組的古新世儲層巖石中發現石油，并表示25/4-15井在Heimdal組中發現了31.5米的油柱，“其中29米是儲層質量良好的砂巖儲層”。

NPD指出，Heimdal組的總厚度為187米，并補充說，在海平面以下2253米的地方遇到了油/水層。NPD指出，在更深的Heimdal砂層中還發現了1.5米長的殘油層，儲層質量良好。

NPD透露，25/4-15井的垂直深度為海平面以下2375米，終止于古新世的Heimdal組。據該組織介紹，現場水深為119米。

“初步計算發現的可采石油規模在50萬至80萬標準立方米之間?！盢PD表示。

該組織補充說：“許可證持有者將評估這一發現和附近的其他發現，以尋求可能的開發?！?/p>

Oil Discovery Made in North Sea

The Norwegian Petroleum Directorate (NPD) revealed Thursday that Aker BP ASA has made an oil discovery in the North Sea through wildcat well 25/4-15 in production license 919.

The NPD, which highlighted that the objective of the well was to prove petroleum in Paleocene reservoir rocks in the Heimdal Formation, said well 25/4-15 encountered a 31.5-meter oil column in the Heimdal Formation, “29 meters of which was a sandstone reservoir with good reservoir quality”.

The Heimdal Formation was 187 meters thick in total, the NPD pointed out, adding that oil/water contact was encountered at 2,253 meters below sea level. A 1.5-meter zone of residual oil was also encountered in deeper Heimdal sand with good reservoir quality, the NPD noted.

Well 25/4-15 was drilled to a vertical depth of 2,375 meters below sea level and was terminated in the Heimdal Formation in the Palaeocene, the NPD revealed. Water depth at the site is 119 meters, the organization outlined.

“Preliminary calculations place the size of the discovery between 0.5 and 0.8 million standard cubic meters of recoverable oil,” the NPD said.

“The licensees will assess the discovery alongside other discoveries in the vicinity with a view towards possible development,” the organization added.
