北里海運(yùn)營公司計(jì)劃為兩個(gè)油田推出一個(gè)新項(xiàng)目

據(jù)7月23日 Neftegaz.RU. 報(bào)道。哈薩克斯坦北里海運(yùn)營公司(North Caspian Operating Company)對標(biāo)普全球表示，在最近的升級和維護(hù)工作之后，該公司計(jì)劃進(jìn)一步增產(chǎn)，并計(jì)劃在本季度為附近的兩個(gè)油田推出一個(gè)新項(xiàng)目。

在一封電子郵件中，這個(gè)由7名成員組成的集團(tuán)的管理層還強(qiáng)調(diào)了應(yīng)對里海海平面波動(dòng)的挑戰(zhàn)。在過去10年里，里海北部哈薩克斯坦淺海地區(qū)的海平面已經(jīng)下降了一米。

卡沙干油田于2000年被發(fā)現(xiàn)，是過去半個(gè)世紀(jì)最大的石油發(fā)現(xiàn)之一，估計(jì)可開采石油儲(chǔ)量在90億至130億桶之間，但在最初的開發(fā)過程中遇到了困難，耗資550億美元。

由殼牌前高管理查德?豪(Richard Howe)領(lǐng)導(dǎo)的NCOC表示，自2016年投產(chǎn)以來，該公司首次大規(guī)模停產(chǎn)，石油日產(chǎn)量已達(dá)到37萬桶。

在35天停工中，包括了一些提高安全和效率的項(xiàng)目，其中包括一個(gè)處理廠的再沸器升級，以及海上注氣系統(tǒng)的改造。NCOC表示，后者能夠大幅增加天然氣注入和石油產(chǎn)量。

該公司表示，目前正在進(jìn)行“初步工程”，有望使卡沙干油田在當(dāng)前開發(fā)階段的日產(chǎn)量超過45萬桶，不過這需要得到投資者的同意和政府的批準(zhǔn)。

與此同時(shí)，NCOC表示，已開始計(jì)劃第二階段，進(jìn)一步提高產(chǎn)量。在第一階段產(chǎn)量穩(wěn)定之前，NCOC似乎一直在回避這一問題。目前，第二階段的發(fā)展規(guī)劃工作正在進(jìn)行中。NCOC計(jì)劃晚些時(shí)候宣布開發(fā)Kashagan油田的概念，這將顯著提高目前水平的產(chǎn)量。

此外，NCOC表示，該集團(tuán)與另一家持有附近Khazar油田開采許可證的合資企業(yè)一起，計(jì)劃在本季度提交Khazar和Kalamkas海上油田的開發(fā)計(jì)劃。

Khazar由殼牌、哈薩克斯坦國家石油公司和阿曼石油公司合資經(jīng)營。NCOC表示，與NCOC聯(lián)合開發(fā)將“最大限度地發(fā)揮協(xié)同作用，并有助于這兩個(gè)領(lǐng)域的經(jīng)濟(jì)可行性”。

“合作開發(fā)”可能需要鉆探50多口井，日產(chǎn)量可能達(dá)到10萬桶，最終投資決定預(yù)計(jì)不遲于2022年。然而，哈薩克斯坦的第一個(gè)聯(lián)合項(xiàng)目仍有“多個(gè)商業(yè)、法律和行政問題”需要解決。報(bào)告稱，來自政府的“持續(xù)支持”將促進(jìn)這類開發(fā)工作的開展。

NCOC由哈薩克斯坦國家石油公司(KazMunaiGaz)、意大利埃尼集團(tuán)(Eni)、道達(dá)爾(Total)、?？松梨?ExxonMobil)和殼牌(Shell)組成，各持有16.81%的股份，中國石油天然氣集團(tuán)公司(CNPC)持有8.33%的股份，日本石油天然氣集團(tuán)公司(Inpex)持有7.56%的股份。

Kashagan consortium eyes output increases, new joint project

Kazakhstan's North Caspian Operating Company, which manages the giant Kashagan oil field, is planning further production increases after recent upgrade and maintenance work, and aims to present a new project for 2 nearby fields in the current quarter, it told S&P Global Platts.

In an email, the management of the 7-member consortium also underlined the challenge of dealing with fluctuating Caspian sea levels, which have fallen by a meter in the last decade in the shallow Kazakh sector of the northern Caspian.

Discovered in 2000, Kashagan was one of the largest oil finds of the last half century, with an estimated 9 billion-13 billion barrels of recoverable oil, but was plagued by difficulties during its initial development, which cost $55 billion.

Oil production volumes have reached 370,000 b/d following the 1st major shutdown since production began in 2016, according to NCOC, which is headed by former Shell executive Richard Howe.

The 35-day shutdown, completed in May, included projects to improve safety and efficiency, among them a processing plant re-boiler upgrade, and a revamp of the offshore gas injection system. The latter "allowed us to substantially increase gas injection and oil production," NCOC said.

"Preliminary engineering" is now underway that could lift Kashagan production above 450,000 b/d under the current development phase, although this would require investor and government approval, it said.

In parallel, NCOC said it had started planning a 2nd phase to further boost production, something it has appeared to shy away from until 1st-phase production was stabilized. "Work is now underway to plan the 2nd stage of development. NCOC plans to announce later the concept of this development of the Kashagan field [which] will significantly enhance production versus the current level," it said.

Additionally, the consortium, together with another venture that holds the license to the nearby Khazar field, aims to submit a development plan for both the Khazar and Kalamkas Sea fields in the current quarter, NCOC said.

Khazar is operated by a joint venture between Shell, KazMunaiGaz and Oman Oil Company. A joint development with NCOC would "maximize synergies and contribute to the economic viability" of both fields, NCOC said.

The "cooperative development" could entail drilling more than 50 wells and production could reach 100,000 b/d, with a Final Investment Decision expected "no later than 2022," it said.

However, there remain to be addressed "multiple commercial, legal and administrative issues" for what is a "1st-of-a-kind" joint project for Kazakhstan. "Continued support" from the authorities will be "enablers to proceeding with this kind of development work," it said.

NCOC comprises KazMunaiGaz, with 16.88%, Italy's Eni, Total, ExxonMobil and Shell with 16.81% stakes each, China's CNPC with 8.33%, and Japan's Inpex with 7.56%.
