Low-Salinity Waterflooding Training Course

Low-Salinity Waterflooding Training Course

Introduction

Low-Salinity Waterflooding Training Course is designed to equip oil and gas professionals with advanced knowledge and practical skills in enhanced oil recovery (EOR), low-salinity water injection, reservoir wettability alteration, and waterflood optimization. Participants will learn how salinity, ionic strength, divalent cations, reservoir temperature, and mineralogical characteristics influence oil displacement efficiency and overall recovery performance. The program also examines the role of smart waterflooding, engineered water injection, reservoir characterization, digital reservoir simulation, and data-driven EOR screening in identifying suitable candidates for low-salinity injection.

The course covers laboratory evaluation techniques, core flooding experiments, compatibility testing, geochemical modeling, injection-water preparation, scale prevention, formation damage management, and production performance analysis. Particular emphasis is placed on integrating laboratory results with field-scale reservoir models to reduce technical uncertainty and improve project economics. The course is suitable for professionals seeking to strengthen their expertise in advanced waterflooding technologies, reservoir engineering, and innovative hydrocarbon recovery solutions.
