石油设备网讯 据8月5日Offshore Energy报道，澳大利亚库珀能源公司(Cooper Energy)的Annie-1天然气勘探井位于澳大利亚近海VIC/P44地区，Cooper拥有该地区50%的权益，而Mitsui E&P Australia是其合作伙伴，也拥有50%权益。
7月下旬，“The Ocean Monarch”号开始从吉普斯兰盆地转移到奥特威盆地，为库珀钻探两口海上天然气探井——Annie-1和Elanora-1。
美国东部时间8月5日(星期一)下午1点，Annie-1井开钻，它位于维多利亚州近海约9公里处，水深58米。该气田位于亨利(Henry)气田(西15公里)和密涅瓦(Minerva)气田(东11公里)之间。
根据Cooper周一声明，Annie-1将是库珀七年来在奥特威盆地近海钻探的第一口天然气勘探井。这口井是该合资公司两口井勘探计划中的第一口——该项目旨在为澳大利亚东南部寻找新的天然气供应来源。
库柏和三井（Mitsui）目前由offshore Casino, Henry和Netherby fields (Casino-Henry合资企业)供应天然气。合资企业希望通过利用其现有的海上基础设施和Minerva天然气厂加工的天然气，开发其他商业天然气。
未来开发项目的应用可能回收的石油估计数量与未发现的储量有关。库柏表示，需要进一步的勘探和评估，才能确定是否存在大量潜在的可移动碳氢化合物。
该井预计需要大约35天来完成，包括钻井、测井、封堵和废弃。“The Ocean Monarch”号将在Annie-1工作计划结束后立即在VIC/L24钻探Elanora-1。Elanora-1将测试该合资企业占地面积中最大的未钻结构，如果成功，将扩建现有生产油田南部的已探明天然气航道。

Cooper spuds first gas exploration well in offshore Otway in seven years
The Diamond Offshore-owned Ocean Monarch drilling rig has spudded Cooper Energy’s Annie-1 gas exploration well located offshore Australia.
The well is located in VIC/P44 where Cooper is the operator with a 50% interest and Mitsui E&P Australia is its partner with a 50% interest.
The Ocean Monarch started mobilization from the Gippsland Basin to the Otway Basin to drill two offshore gas exploration wells – Annie-1 and Elanora-1 – for Cooper in late July.
The Annie-1 well was spudded at 1:00 pm AEST on Monday, August 5. It is located approximately 9 km offshore Victoria in a water depth of 58 meters.
The prospect is located between the Henry (15 km west) and Minerva (11 km east) producing gas fields.
According to Cooper’s statement on Monday, the Annie-1 will be the first gas exploration well drilled offshore in the Otway Basin in seven years. The well is the first in a two-well exploration program by the joint venture to identify new sources of gas supply for south-east Australia.
Cooper Energy and Mitsui currently supply gas from the offshore Casino, Henry and Netherby fields (Casino-Henry Joint Venture). The joint venture expects to develop any commercial gas discoveries through utilization of its existing offshore infrastructure and process gas at the Minerva Gas Plant, which the joint venture parties have contracted to acquire.
The estimated quantities of petroleum that may be potentially recovered by the application of future development project(s) relate to undiscovered accumulations. These estimates have both an associated risk of discovery and a risk of development. Further exploration, appraisal and evaluation is required to determine the existence of a significant quantity of potentially moveable hydrocarbons, Cooper said.
The well is scheduled to take approximately 35 days to complete, with the success work program including drilling, logging and plugging and abandonment. The Ocean Monarch will move to drill Elanora-1 in VIC/L24 immediately after the Annie-1 work program. Elanora-1 will test the largest, undrilled structure in the joint venture’s acreage and if successful will extend the proven gas fairway south of the existing producing fields.
