埃克森美孚削减圭亚那原油产量

据路透社6月15日消息，南美国家圭亚那的环境监管机构周一表示，由于天然气回注设备出现问题，埃克森美孚已削减其在圭亚那沿海新项目的原油产量，此举旨在避免天然气过度燃除。

圭亚那环境保护局负责人文森特?亚当斯(Vincent Adams)表示，由于天然气回注设备出现问题，过去一周内，由埃克森美孚、赫斯公司和中海油联合运营的利萨(Liza)油田的日产量已降至2.5万至3万桶之间。

这一数字低于5月初时的7.5万至8万桶/天，当时有关部门曾预计，到6月，该油田的产量将升至12万桶/天。该油田去年12月开始投产，燃起了人们对这个经济落后国家日益繁荣的希望。

亚当斯说，如果压缩机功能未能充分发挥，无法将随原油一起产生的气体重新注入储层，埃克森美孚不得不降低原油产量，以避免超过1500万立方英尺/天的天然气燃除上限。

为了减少温室气体的排放，世界各地的石油公司都在寻求减少天然气燃除。但在像圭亚那这样缺乏天然气管道基础设施的地方，这是很复杂的。

从圭亚那的海上Stabroek区块到海岸的天然气管道建设计划尚未启动。

Exxon cuts Guyana crude output to avoid gas flaring -regulator

Exxon Mobil Corp has reduced crude output at its nascent project off Guyana’s coast due to problems with gas reinjection equipment, a move meant to avoid excessive gas flaring, the South American country’s environmental regulator said on Monday.

Output at the Liza field, which Exxon operates in a consortium with Hess Corp and CNOOC Ltd, has fallen to between 25,000-30,000 barrels per day within the past week after an issue with gas reinjection equipment, according to Vincent Adams, head of Guyana’s Environmental Protection Agency.

That was down from between 75,000-80,000 bpd in early May, when authorities had anticipated that output from the field - which began production in December, raising hopes for increased prosperity in the impoverished country - would rise to 120,000 bpd by June.

Without the compressor fully functioning in order to reinject gas produced alongside the crude into the reservoir, Exxon had to reduce crude output to avoid exceeding a 15 million-cubic feet per day limit agreed to with authorities for gas flaring, Adams said.

Oil companies worldwide are seeking to reduce gas flaring from their operations in order to reduce greenhouse gas emissions. But that is complicated in places like Guyana, which lack gas pipeline infrastructure.

Plans to build a gas pipeline from Guyana’s offshore Stabroek block to the coast have not yet gotten off the ground.
