據(jù)世界石油周刊6月1日報道，圭亞那正準(zhǔn)備啟動一項(xiàng)天然氣發(fā)電項(xiàng)目的招標(biāo)，該項(xiàng)目位于埃克森美孚運(yùn)營的Stabroek區(qū)塊。

該項(xiàng)目將需要安裝一條160公里長的海底天然氣管道，從深水區(qū)塊到陸上發(fā)電廠和其它設(shè)施。

根據(jù)政府的計劃，Stabroek的Liza項(xiàng)目將提供約3000萬-5000萬立方英尺/天的天然氣，足以滿足250兆瓦的發(fā)電能力。

政府表示，該項(xiàng)目將允許圭亞那國營電力公司GPL將其電站從重油轉(zhuǎn)換，并以較低的生產(chǎn)成本提供電力。

GPL是人口稀少的圭亞那最大的發(fā)電公司，裝機(jī)發(fā)電量為120兆瓦，而全國需求約為205兆瓦。其余供應(yīng)來自與采礦、林業(yè)和制糖相關(guān)的獨(dú)立發(fā)電商和聯(lián)合發(fā)電商。

該國環(huán)境機(jī)構(gòu)EPA表示，埃克森美孚目前正在利用從Liza油田開采的天然氣來注入其油井，并為其浮式生產(chǎn)儲油和卸油裝置提供動力。燃燒占剩余的1400萬到1500萬立方英尺/天。

該公司圭亞那辦事處告訴Argus表示，Liza項(xiàng)目的啟動需要臨時點(diǎn)火，以完全啟動天然氣壓縮注入系統(tǒng)。我們已經(jīng)成功啟動了天然氣處理系統(tǒng)，并開始將天然氣注入儲層。

據(jù)能源部主任Mark Bynoe稱，天然氣到陸上的項(xiàng)目計劃“非常超前”。

他表示:“我們有一份諒解備忘錄草案，以及一個由政府內(nèi)部關(guān)鍵成員組成的非常有說服力的工作小組。“我們希望私營部門也參與進(jìn)來，這樣他們就能明白機(jī)會是什么。

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."
