圭亚那计划启动天然气发电项目招标

据世界石油周刊6月1日报道，圭亚那正准备启动一项天然气发电项目的招标，该项目位于埃克森美孚运营的Stabroek区块。

该项目将需要安装一条160公里长的海底天然气管道，从深水区块到陆上发电厂和其它设施。

根据政府的计划，Stabroek的Liza项目将提供约3000万-5000万立方英尺/天的天然气，足以满足250兆瓦的发电能力。

政府表示，该项目将允许圭亚那国营电力公司GPL将其电站从重油转换，并以较低的生产成本提供电力。

GPL是人口稀少的圭亚那最大的发电公司，装机发电量为120兆瓦，而全国需求约为205兆瓦。其余供应来自与采矿、林业和制糖相关的独立发电商和联合发电商。

该国环境机构EPA表示，埃克森美孚目前正在利用从Liza油田开采的天然气来注入其油井，并为其浮式生产储油和卸油装置提供动力。燃烧占剩余的1400万到1500万立方英尺/天。

该公司圭亚那办事处告诉Argus表示，Liza项目的启动需要临时点火，以完全启动天然气压缩注入系统。我们已经成功启动了天然气处理系统，并开始将天然气注入储层。

据能源部主任Mark Bynoe称，天然气到陆上的项目计划“非常超前”。

他表示:“我们有一份谅解备忘录草案，以及一个由政府内部关键成员组成的非常有说服力的工作小组。“我们希望私营部门也参与进来，这样他们就能明白机会是什么。

Guyana to tender a gas-to-shore project

Guyana is preparing to launch a tender for a natural gas-to-power project anchored on the ExxonMobil-operated Stabroek block.

The project would entail the installation of a 160km subsea gas pipeline from the deepwater block to onshore power generation units and other facilities.

Around 30mn-50mn cf/d would be delivered from the Liza project on Stabroek , enough to fire around 250MW of generating capacity, according to the government's plans.

The project will allow Guyana's state-run power utility GPL to convert its stations from heavy fuel oil and deliver electricity at lower production costs, the government says.

GPL is sparsely populated Guyana's largest power generator with 120MW of installed capacity, compared with national demand of about 205MW. The remaining supply comes from independent power producers and cogenerators tied to mining, forestry and sugar production.

ExxonMobil is currently using gas from the Liza field to reinject into its oil wells and to power its floating production storage and offloading unit. Flaring accounts for the remaining 14mn-15mn cf/d, the country's environmental agency EPA said.

"Start up for the Liza project involves temporary flaring to fully commission the gas compression an injection system," the company's Guyana office told Argus.

"We have successfully started up the gas handling system and begun gas injection into the reservoir."

The gas-to-shore project plans "are far advanced," energy department director Mark Bynoe said.

"We have a draft memorandum of understanding and a very cogent working group made up of critical players within the government," he said. "We hope to engage the private sector as well so that they can understand what the opportunities are."
