殼牌將探索在超深水墨西哥灣發(fā)現(xiàn)石油所有選項(xiàng)

據(jù)石油新聞2020年8月28日墨西哥城報(bào)道，荷蘭皇家殼牌公司將對(duì)其位于超深水墨西哥灣的其中一個(gè)區(qū)塊進(jìn)行勘探計(jì)劃中所允許的所有勘探活動(dòng)，來(lái)充分了解該區(qū)塊的潛力。

墨西哥國(guó)家碳?xì)浠衔镂瘑T會(huì)(CNH) 8月28日全體一致批準(zhǔn)了殼牌公司有關(guān)執(zhí)行所有Xochicalco-1EXP勘探計(jì)劃中允許的勘探活動(dòng)的請(qǐng)求，其中包括鉆取一口補(bǔ)充井和一口側(cè)鉆井。Xochicalco-1EXP是一個(gè)位于距離墨西哥北部塔毛利帕斯州坦皮科市海岸123英里海域的油田。

殼牌公司技術(shù)顧問(wèn)埃爾南德斯·佩雷斯在8月28日舉行的網(wǎng)絡(luò)直播會(huì)議上說(shuō)，殼牌公司將在5英里深處鉆第二口井，設(shè)法鉆到Wilcox地層，該地層預(yù)計(jì)儲(chǔ)量可達(dá)5.62億桶油當(dāng)量?！づ謇姿拐f(shuō)，殼牌公司曾在6月份要求進(jìn)行“這些”活動(dòng)。

殼牌公司將使用由總部設(shè)在墨西哥的Grupo R建造的Muralla IV半潛式平臺(tái)。殼牌公司最初在2019年6月獲得批準(zhǔn)的勘探計(jì)劃所需費(fèi)用現(xiàn)在將從1.04億美元增至3.458億美元，因?yàn)闅づ乒緵Q定加大勘探鉆井的力度，以更好地了解儲(chǔ)油層。

CNH技術(shù)顧問(wèn)羅德里戈· 費(fèi)爾南德斯在去年6月該計(jì)劃獲得批準(zhǔn)時(shí)表示，Xochicalco-1EXP油田位于佩爾迪多褶皺帶，該地區(qū)以前幾乎沒(méi)有進(jìn)行過(guò)勘探活動(dòng)，而且距離任何現(xiàn)有的基礎(chǔ)設(shè)施都很遠(yuǎn)，因此在技術(shù)上具有挑戰(zhàn)性。

殼牌公司迄今在墨西哥舉行的數(shù)輪招標(biāo)中贏得了11個(gè)區(qū)塊，其中9個(gè)區(qū)塊位于墨西哥灣深水區(qū)。

墨西哥國(guó)家石油公司(Pemex)在其2019-2023年商業(yè)計(jì)劃中決定推遲對(duì)深水油田的所有投資，將重點(diǎn)放在淺水和陸上油田，以最大限度地提高短期產(chǎn)量。Pemex在其歷史上曾先后共鉆取了50多口深水井，但沒(méi)有取得任何成功的成果。

Shell to explore all options to find oil in the Mexican ultra deepwater Gulf of Mexico

Shell will conduct all the activities allowed in the exploration plan for one of its blocks in the ultra deepwater Gulf of Mexico as it seeks to fully understand its potential.

The National Hydrocarbons Commission (CNH) on Aug. 28 unanimously approved Shell's request to carry out all the permitted activities in the exploration plan for its Xochicalco-1EXP, a field located 123 miles off the coast of the city of Tampico, in the Northern state of Tamaulipas, which include drilling one additional well and a sidetrack.

Shell will drill the second well at depths of five miles trying to reach a Wilcox formation, with prospective reserves of as much as 562 million barrels of oil equivalent, said Israel Hernandez Perez, technical advisor, during a webcast session on Aug. 28. Shell requested "these" activities in June, Hernandez Perez said.

Commissioners acknowledged the importance of having exploration activities in the area to ultimately obtain resources. Commissioner Alma Porres Luna highlighted the fact that Shell has decided to use a local contractor to conduct these activities.

Shell will use the Muralla IV semi-submersible platform, built by Mexico-based Grupo R.

Shell’s exploration plan, which was originally approved in June 2019, will now go from $104 million to $345.8 million, as the company decides to drill more to better understand the reservoir.

Xochicalco is located in the Perdido fold belt, an area with very little prior exploration activity and far from any existing infrastructure, which makes it technically challenging, Rodrigo Hernandez, another technical advisor said in June 2019, when the plan was approved.

The block, included in contract CNH-R02-L04-AP-PG07/2018, has only one other area near by, which is also operated by Shell, Hernandez said.

Shell won 11 blocks during Mexico′s rounds, nine of which are in Mexican deepwaters, making it the company with the biggest exposure to those formations.

Mexico's Pemex, which has drilled over 50 deepwater wells in its history without any successful results, decided in its 2019-2023 business plan to postpone all investments in deepwaters to focus on shallow-waters and onshore fields to maximize its short-term production.
