据油价网1月31日消息称，英国石油巨头英国石油公司（bp）开始钻探两口新的勘探井，以寻找里海深处的天然气。

目前，阿塞拜疆正进口天然气，以满足日益增长的国内需求和现有的出口合同。巴库还承诺在五年内将对欧洲的出口增加一倍。

英国石油公司本月表示，其中一口井将深达7000米，开采据信位于现有Shah Deniz气田下方的一个气藏，目前阿塞拜疆的大部分天然气出口都来自该气田。这口井预计需要一年左右的时间才能完工，它将确定深层储层中的天然气是否可以进行商业开采。

英国石油公司表示，第二口井将达到约4500米的深度，目标是阿塞拜疆主要油田Azeri-Chirag-Guneshli (ACG)油田下面的一个可能的油藏。该钻井项目将沿着现有井的部分深度进行，因此预计在三个月内完成。

深海海上钻井非常昂贵，每口井的成本高达数千万美元。

BP Taps Deep Gas Reservoirs In Azerbaijan’s Caspian Sea

UK oil giant BP has started drilling two new exploration wells to search for gas deep beneath the Caspian Sea.

The announcement comes as Azerbaijan imports gas to meet both growing domestic demand and existing export contracts. Baku has also pledged to double exports to Europe within five years.

One of the wells will reach a depth of 7,000 meters, BP said this month, to tap a gas reservoir believed to lie below the existing Shah Deniz gas field, which currently provides the bulk of Azerbaijan's gas exports. This well, which is expected take around a year to complete, should confirm whether gas in the deep reservoir can be extracted commercially.

BP said the second well, which will reach a depth of about 4,500 meters, is targeting a possible reservoir below Azerbaijan's main oil field, the Azeri-Chirag-Guneshli (ACG) field. This drilling project will follow an existing well for part of its depth and so is expected to be completed in just three months.

Offshore drilling in deep water is enormously expensive, with each well costing many tens of millions of dollars.
