Abstract

Abstract: To understand the genesis of inclined water oil contact in Nahr Umr clastic reservoir of Albian stage in Rumaila oilfield and improve the accuracy of oil and gas reserves estimation and rationality of development plan and adjustment, four aspects are discussed including formation water discharge, inclination degree of water oil contact (WOC) , characteristics of oil and water pressure gradient response and regional pressure variation by analyzing the data of well logging, wireline formation pressure and regional geology, based on the summaries of the different causes of inclined WOC. It is considered that hydrodynamism is the main reason to result in the inclination of WOC in clastic reservoir of Albian Nahr Umr formation and the hydrodynamic force is sourced from the surface water supply in Teros-Zagros thrust-fault fold belt in the northeastern part of the oilfield
