圭亚那将缓解埃克森美孚FPSO原油减产的影响

据石油世界期刊4月20日西班牙港报道，日前，圭亚那自然资源部表示，圭亚那正在考虑采取未指明的经济措施，以缓解美国石油巨头埃克森美孚(ExxonMobil)深水Stabroek区块多次减产的影响。

自2019年12月开始产油以来，Liza Destiny浮式生产储存卸载（FPSO）船屡次出现技术问题，导致产量下降。由于这些问题，本周的产量从12万桶/天削减到3万桶/天。

该国政府表示，对埃克森美孚未能纠正反复出现的问题感到“非常失望”，而且“……正在研究产量损失的影响，以及由此造成的收入和收益损失，包括可能不得不采取的保护国家利益的措施。”

埃克森美孚表示，最新的问题是排气消音器，它是最近维修和重新安装的气体压缩机的一部分。该公司对Argus表示，“对该部门持续表现不佳感到非常失望。”该公司正与压缩设备制造商曼恩能源解决方案公司（man energy solutions）和FPSO的运营商SBM Offshore合作，以纠正这种情况。

这是该公司第三次因技术问题而削减Liza Destiny的产量。去年首次出现的问题将2020年6月的产量降至2.75万桶/日的低点，并延迟了FPSO在去年12月之前达到12万桶/日的目标，比计划晚了9个月。

埃克森美孚没有表明，预计何时能解决问题、提高原油产量。

埃克森美孚表示，最近的天然气压缩机问题迫使埃克森美孚将产量降至“最低水平，以缓解水下系统中水合物的形成，维持向发电机的天然气注入和燃料气，并将燃烧降至最低”。

Guyana planning to offset Exxon FPSO crude output cuts

Guyana is considering unspecified economic measures to cushion the impact of repeated production cuts from US major ExxonMobil's deepwater Stabroek block, the natural resources ministry said.

Since it started oil production in December 2019 there have been repeated technical issues on the Liza Destiny floating production, storage and offloading (FPSO) vessel that have cut output. This week production was cut from 120,000 b/d to 30,000 b/d because of such issues.

The government said it is "highly disappointed" that ExxonMobil has been unable to rectify recurring problems, and "... is examining the implications of the loss of output, and consequently loss of income and revenue, including measures that it may have to institute to protect national interest."

The latest problem is with a discharge silencer that is part of a recently repaired and reinstalled gas compressor, ExxonMobil said. The company told Argus it is "extremely disappointed by the continued underperformance of this unit." It is working with compression equipment manufacturer MAN Energy Solutions and the FPSO's operator, SBM Offshore, to rectify the situation.

This is the third time the technical problems have forced the company to trim output on the Liza Destiny . The issue that first arose last year suppressed production to a low of 27,500 b/d in June 2020, and impeded the FPSO from reaching a 120,000 b/d target until December, nine months behind schedule.

ExxonMobil has not indicated when it expects the problem to be rectified and crude output increased.

The latest problem with the gas compressor forced ExxonMobil to reduce production "to a minimum level that mitigates formation of hydrates in subsea systems, maintains gas injection and fuel gas to the power generators, and minimizes flare," the company said.
