Dynamic Investigation of Silicate Preformed Particle GELS (SPPGS) Using Transparent Fracture Model (Hele-Shaw Cell) and Simulator

Summary Implementing conformance treatments has been essential for enhanced oil recovery in recent years. Reducing water production becomes an issue for the oil industries when it competes directly with oil rates. Enhanced Preformed Particle Gels (PPGs) are one of the superabsorbent materials to shut off high permeable zones and promote flood sweep improvement. This research aims to evaluate the behaviour of in-house synthesized silicate preformed particle gels (SPPGs) through Hele-Shaw cell as a dynamic test. The experimental results were validated with the model and implemented into a reservoir simulator called UTCHEM. Various injection rates were injected in the silicate gel model of the modified simulator. We obtain that the simulation results contain assumption for the silicate gel injection are compatible with the experimental values obtained from injections of SPPG through Hele-Shaw Cell. The results indicate that gel injection pressure increases with flow rate. After Gel placement, results showed that water flood pressure decreases as the fracture width increases from 0.5 mm to 1 mm. Simulation results indicated a 21% pressure increase while using silicate gel.
