Chemical EOR economics of Sabriyah Lower Burgan reservoir: a reservoir sector model study

This research focuses on the applicability of implementing a multi-well pilot test for a chemical enhanced oil recovery (CEOR) in Sabriyah Lower Burgan reservoir that is located in the north of Kuwait. The objective of this research is to evaluate the economic applicability of a proposed Alkaline Surfactant Polymer (ASP) formulation in a multi-well pattern in the candidate reservoir. Simulation and economic modelling was used for this evaluation. Sabriyah Lower Burgan is a large sandstone reservoir located in north Kuwait. The reservoir has excellent rock properties permeabilities are in Darcies. The field is currently developed through primary depletion with an active water drive. Using the CEOR screening criteria, the reservoir is a candidate for the recommended technology. All forms of EOR were evaluated and CEOR was the only practical technology that passed all screening criteria. Understanding the reservoir is critical and evaluating multiple implementation strategies is important to insure economic success. The objective of the pilot test is to demonstrate that the recommended ASP formulation can economically mobilize remaining oil (ROS) in Sabriyah Lower Burgan reservoir. The process to achieve this objective includes: • Expand a small scale pilot into a large multi-well pilot from the proposed area location. • Select suitable target reservoir zone. • Evaluate different well pattern strategies using simulation demonstrating the effectiveness of the technology in producing additional oil. • Apply economics to all case studies to demonstrate the applicability and commerciality of the different proposed case studies. • List observation of key challenges associated with large scaled field implementation. Including economics in a technical CEOR assessment will help understand the practical aspects of field implementation for the Sabriyah Lower Burgan field.
