Multilateral Waterflood of a Low-Permeability Carbonate Reservoir

摘要

The Shuaiba limestone reservoir of the Saih Rawl field in Oman is a nearly unfaulted, low-relief structure of large areal extent. permeability is matrix dominated and relatively low. The reservoir contains approximately 90 X 10~6 m~3 of 35 deg API oil. Today, multilateral wells with as many as severn legs are used in a pattern waterflood development. A field-development review identified additional short-and long-term development opportunities.
