據(jù)油田技術9月9日消息稱,Equinor在2018年從道達爾接管該油田的運營商之前,對馬丁林格油田的鉆井進行了深入分析。
這項審查得出的結論是,有幾口井沒有必要的防護層。因此,Equinor計劃鉆探新井,以確保安全生產(chǎn)。
2018年之前在馬丁林格油田鉆探四口氣井中存在防護層缺陷,這些被認為不適于安全生產(chǎn)。
派特洛對油井防護層進行了獨立評估,以支持了運營商的觀點。
Equinor負責技術、項目和鉆井的代理副總裁Geir Tungesvik說:“目前,這些井被認為是安全的,但我們將繼續(xù)封井,并對其進行持續(xù)監(jiān)控,直到我們通過從其他井中開采來降低地層壓力。安全始終是第一要務?!?/span>
馬丁林格工廠專為油氣混合而設計,需要以一定速度生產(chǎn)的氣井來啟動和生產(chǎn)。
Tungesvik 表示:“我們的首要任務是確保安全啟動該領域。我們的首要任務是確保油田的安全啟動。因此,除了開發(fā)與運營計劃(PDO)中剩余的兩口氣井外,我們計劃再鉆三口新的氣井,以按照原計劃生產(chǎn)?!?/span>
鉆探三口新井的成本總計約為2 0億挪威克朗。
Equinor將向挪威當局提供所有正在開發(fā)的項目的最新信息,包括Covid-19的后果。該計劃將與十月份國家預算的發(fā)布一起發(fā)布。
馬士基Intrepid鉆機最近開始在馬丁林格進行鉆探作業(yè)。
Equinor是馬丁林格(70%)的大股東和運營商。派特洛(30%)是唯一的合作伙伴。

Equinor to conduct further drilling at Martin Linge field
Equinor has conducted an in-depth analysis of the wells drilled at Martin Linge before the company took over as the operator of the field from Total in 2018.
This review concluded that several of the wells do not have the necessary barriers. Equinor therefore plans to drill new wells in order to ensure safe production.
In the four gas wells that were drilled at Martin Linge before 2018 well barrier deficiencies that are considered to make them inappropriate for safe production have been established.
Petoro has carried out an independent assessment of well barriers that support the operator's view.
“The wells are considered safe as they are now, but we will keep them plugged and under continuous monitoring until we have reduced the pressure in the formation by producing from other wells. Safety is always priority number one,” said Geir Tungesvik, acting EVP for Technology, Projects and Drilling in Equinor.
The Martin Linge plant is designed for a mixture of oil and gas, and needs gas wells that produce at a certain rate for start-up and production.
“Our number one priority is to ensure safe start-up of the field. We will therefore plan to drill up to three new gas wells in addition to the two remaining wells from the plan for development and operation (PDO) for the field to produce as originally planned,” said Tungesvik.
The costs of drilling up to three new wells total about NOK2 billion.
Equinor will give an update on all projects under development to Norwegian authorities, including the consequences of Covid-19. The plan will be published in connection with the presentation of the state budget in October.
The Maersk Intrepid drilling rig recently started the drilling operations at Martin Linge.
Equinor is the majority shareholder and operator of Martin Linge (70%). Petoro (30%) is the only partner.
