石油设备网讯 据海上石油新闻网5月12日伦敦报道，荷兰Sewell & Associates公司(NSAI)日前完成了对位于摩洛哥海上Lixus许可证区块内的安舒瓦-1天然气发现附近的卫星远景构造的评估。
新运营商Chariot石油天然气公司委托NSAI进行了这项研究，NSAI已把安舒瓦发现和卫星远景构造的剩余可采资源量提升至1万亿立方英尺以上。
其中安舒瓦北被确定为低风险优先级卫星远景构造，拥有3080亿立方英尺的远景资源量以及地质成功的概率为43%。
有关位于该许可证区块内5个远景区块的后续矿业专家报告将在重新处理三维地震资料后完成。
2009年，西班牙雷普索尔公司在距离摩洛哥海岸40公里(24英里)水深388米(1273英尺)海域中钻遇了发现井安舒瓦-1井，在两个平均孔隙度从25%到28%不等的砂层中，发现井钻遇了55米(180英尺)厚的纯产气层。
NSAI估计发现井的2C储量为3070亿立方英尺，在一个没有被发现井钻透的更深的目标层里可能蕴藏着1160亿立方英尺的天然气资源量。
这5个卫星远景构造都被认为对以安舒瓦发现为基础的开发具有回接潜力。

Review suggests more gas close to Anchois offshore Morocco
Netherland Sewell & Associates Inc. (NSAI) has completed its review of satellite prospects adjacent to the Anchois-1 gas discovery in the Lixus license offshore Morocco.
New operator Chariot Oil & Gas commissioned the study, which has upgraded remaining recoverable resources to more than 1 tcf for Anchois and the satellites.
Among these, Anchois North is confirmed as the low risk priority satellite prospect with 308 bcf of prospective resources and a probability of geological success of 43%.
A follow-up Competent Persons Report on five more prospects in the license will be completed after reprocessing of 3D.
Repsol drilled the Anchois-1 discovery well in 2009 in 388 m (1,273 ft) water depth, 40 km (24 mi) from the coast, encountering estimated net gas pay of 55 m (180 ft) in two sands with average porosities ranging from 25% to 28%.
NSAI estimates a 2C resource of 307 bcf, with potentially 116 bcf in a deeper target not penetrated by that well.
The five satellite prospects are all thought to have tieback potential to an Anchois-based development.
