Beyond 94% Water Cut: How Targeted Polymer Diversion Unlocked 47,100 bbl of Incremental Oil in a High-Salinity ReservoirBeyond 94% Water Cut: How Targeted Polymer Diversion Unlocked 47,100 bbl of Incremental Oil in a High-Salinity Reservoir

Executive Summary This case study examines the application of a tailored Polymer Dispersed System (PDS) in a mature oil field characterized by extreme vertical heterogeneity and high formation water salinity

A Paradigm Shift in Carbonate Water Shut-Off: First Laboratory Demonstration of PDS Stability and Selective Activation at 120°C and 225,000 ppm SalinityA Paradigm Shift in Carbonate Water Shut-Off: First Laboratory Demonstration of PDS Stability and Selective Activation at 120°C and 225,000 ppm Salinity

Technical Case Study – Laboratory Breakthrough 1. The HTHS Carbonate Challenge: Why Conventional Solutions Fail Carbonate reservoirs hold approximately 60% of the world’s remaining conventional oil reserves, yet they present
