Comprehensive review of enhanced oil recovery strategies for heavy oil and bitumen reservoirs in various countries: Global perspectives, challenges, and solutions.

This study presents a comprehensive review of enhanced oil recovery (EOR) methods tailored specifically for high permeable heavy oil/bitumen (HOB) reservoirs, encompassing reservoir properties, production techniques, and associated challenges. In contrast to existing literature, this research uses a novel approach by delving into the production history and methodologies employed in prominent HOB-producing countries. As a result, some comprehensive primary reservoir threshold criteria are created via coupling the presented information in various literatures.

A comprehensive evaluation of the effect of key parameters on the performance of DTPA chelating agent in modifying sandstone surface charge.

Despite the positive aspects of low salinity water (LSW), this technique is relatively expensive and unavailable in some countries. Furthermore, potential problems associated with LSW such as scale precipitation in carbonate reservoirs and fine migration in sandstone reservoirs raise concerns. Chelating agents have the ability to chelate metal ions from solution, effectively reducing the salinity of seawater (SW) and mimicking the behavior of LSW.
