Natih B 水库位于阿曼北部最大油田之一的地层内。由于储层背景复杂、天然裂缝定位困难,过去几十年来,储层开发经历了多次挑战。开发此类致密碳酸盐岩的成功取决于高质量地震、钻孔图像、岩石物理学和动态数据的整合。整篇论文的目标是开发一种集成技术方法,可用于释放运营商当前投资组合中最大的未开发资源之一。

介绍

Natih B 感兴趣的开发区域最初蕴藏着约 10 亿桶石油,是运营商投资组合中重要的未开发资源。

Natural Fractures Help Unlock Tight Carbonates in Oman

The authors of this paper develop an integrated technical approach that can be used to unlock one of the largest undeveloped resources in an operator’s portfolio.

Within the stratigraphy of one of the largest fields in north Oman is the Natih B reservoir. The development of the reservoir has undergone several challenges over the past decades because of the complexity of the reservoir setting and difficulties in locating the natural fractures. Success in developing such tight carbonates depends on the integration of high-quality seismic, borehole imagery, petrophysics, and dynamic data. The objective of the complete paper is to develop an integrated technical approach that can be used to unlock one of the largest undeveloped resources in the operator’s current portfolio.

Introduction

With approximately 1 billion bbl of oil originally in place in the development area of interest, Natih B is a significant undeveloped resource in the operator’s portfolio.
