Abstract

Summary Leviathan is a giant natural gas field located ∼130km west of the Israeli port city of Haifa, in water depths of ∼1,700m, and discovered in late 2010 by a venture consisting of Noble Energy (Operator), Delek Drilling and Ratio Oil Exploration. With over 33 trillion cubic feet of natural gas resources in place (over 21 Tcf recoverable), it is the largest natural gas field discovered in the Eastern Mediterranean and one of the largest deep-water natural gas discoveries in the world. Here we provide a brief geological overview of the basin and play, and then focus on the properties and architecture of the Leviathan gas field, based on a comprehensive database, comprising of seismic, well logs, lab data, and flow tests. The Leviathan gas field is expected to come on line by the end of 2019, with a 1.2 billion cubic feet per day capacity, supported by four high rate sub-sea wells, tied back to a fixed leg processing platform. Leviathan’s future lies in expanding the throughput of the gas field, and potentially in deeper units where several prospective targets, assumed to be of Mesozoic age, were identified in association with a large deep-rooted paleo-high.
利维坦油田——发现九年来第一次发现天然气
利维坦是一个巨大的天然气田,位于以色列港口城市海法以西约130公里处,水深约1700米,由Noble Energy(运营商)、Delek Drilling和Ratio Oil Exploration组成的合资企业于2010年底发现。它拥有超过33万亿立方英尺的天然气资源(超过21万亿立方英尺的可采储量),是地中海东部发现的最大的天然气田,也是世界上最大的深水天然气发现之一。在此,我们将简要介绍该盆地和区块的地质概况,然后基于一个综合数据库,包括地震、测井、实验室数据和流动测试,重点介绍利维坦气田的性质和结构。Leviathan气田预计将于2019年底投产,日产量为12亿立方英尺,由4口高速海底井支撑,并与固定腿处理平台相连。利维坦的未来在于扩大气田的产量,并可能在更深的单元中发现几个有前景的目标,假设是中生代,与一个大型深根古隆起有关。
