據(jù)海上工程師網(wǎng)報道，奧地利能源和石化公司（OMV）旗下的挪威分公司9月23日證實，該公司部署在挪威北海的Oswig勘探井日前獲得了凝析油發(fā)現(xiàn)。 

擔(dān)任運營商的OMV挪威分公司表示，該公司和合作伙伴現(xiàn)在決定在這口發(fā)現(xiàn)井上另鉆新孔，并進行中途測試（DST），合作伙伴Longboat能源公司表示，這口發(fā)現(xiàn)井可能是“挪威今年正在測試的最大天然氣遠景構(gòu)造之一”。  

Oswig勘探井的水下真實垂直深度為5003米，目標是塔伯特地層和內(nèi)斯地層。塔伯特地層鉆遇到了天然氣和凝析油。在井位上，無法確定內(nèi)斯地層深處是否存在碳氫化合物。

Longboat能源公司表示，Oswig勘探井由一個高壓、高溫的侏羅紀旋轉(zhuǎn)斷塊組成，“鉆前的無風(fēng)險平均總資源量估計為9300萬桶油當量”。

Longboat能源公司表示，值得肯定的鉆井結(jié)果，以及從現(xiàn)有井眼收集全套井下動態(tài)數(shù)據(jù)的挑戰(zhàn)，導(dǎo)致他們決定在發(fā)現(xiàn)井上另鉆新孔并進行DST。 

另鉆新孔并進行DST將評估上塔伯特地層的產(chǎn)能，需要6-8周的時間完成，并需要得到監(jiān)管部門的批準。 

Longboat能源公司表示，已經(jīng)在該區(qū)塊上發(fā)現(xiàn)了幾個額外的斷塊，這些斷塊可能包含8000萬桶油當量的無風(fēng)險平均資源，如果DST成功實施，將大大降低風(fēng)險。 

Longboat能源公司補充說，自2002年投產(chǎn)以來，位于發(fā)現(xiàn)井附近的Tune油田迄今已產(chǎn)1.4億桶油當量。  

OMV挪威分公司是該許可證的運營商，擁有40%的開采權(quán)益。 許可證合作伙伴為Source能源公司（20%）、溫特斯豪Dea挪威公司（20%）和Longboat能源挪威分公司 （20%）。

OMV Confirms Find in One of "Largest Prospects in Norway"

The Norwegian arm of Austrian energy and petrochemicals company OMV has confirmed that the Oswig exploration well in the Norwegian North Sea has made a gas-condensate discovery. 

OMV (Norge), as operator, said that it and its partners had now decided to drill a sidetrack and perform a drill stem test (DST) on the well, which partner Longboat says could be "one of the largest gas prospects being tested in Norway this year". 

The well was drilled to a depth of 5,003 metres TVDSS targeting the Tarbert and Ness formations. Gas and condensate were encountered in the Tarbert Formation. Presence of hydrocarbons in the deeper Ness formation was inconclusive at the well location.

Partner Longboat Energy says Oswig consists of a high pressure, high temperature Jurassic rotated fault block "with a pre-drill gross unrisked mean resource of 93 mmboe".  

It said that the positive result, as well as challenges collecting a full suite of downhole dynamic data from the existing well-bore led to the decision to sidetrack the well and perform the DST. 

This will evaluate productivity of the Upper Tarbert Formation and will take 6-8 weeks to complete and is subject to regulatory approvals.

Longboat Energy said that several additional fault blocks have been identified on-block which could contain further gross unrisked mean resources of 80 mmboe which would be significantly derisked by a successful DST. 

It added that the nearby Tune field has produced circa 140 mmboe since production commenced in 2002.

OMV (Norge) AS is the operator for the license with a 40 percent working interest. The license partners are Source Energy AS (20%), Wintershall Dea Norge AS (20%) and Longboat Energy Norge AS (20%).
