SL-POLYHIB polyamine based shale inhibitor is designed for water based & polymer based drilling fluids. SL-POLYHIB equips strong absorption and strong inhibition advantages, also it could overcome high flocculation, high volume fluid loss.
Before the consideration of bio-inhibitors as potential shale inhibitors, several conventional inhibitors were used. Herein, a few conventional inhibitors are discussed. The use of clay stabilizers was long practised in the waterflooding of conventional sandstones, before being used in drilling and fracturing treatments for gas and oil shales
