Microgel Placement And Plugging Performance In Sand Filled Fracture For Conformance Control, Baihua Lin

Masters Theses

“Preformed particle gels (PPG) has been widely applied for conformance control in heterogeneous reservoirs with fractures and super-K channels. As a plugging agent, PPG could plug the fractures or high permeability streaks and divert the displacing fluid into low permeability matrix. Many studies have been conducted to investigate the potential of PPGs as a water cut reduction and improved oil recovery agent using homogeneous sandpacks or heterogeneous core samples with man-made open fractures. However, no research has been carried out to understand how PPG injection and plugging performance will be changed if the fractures are filled with sands. Herein, the …
