Preformed Particle Gels (PPGs) treatment is one of the most promising solutions to improve conformance control in mature water flooded oil reservoirs. It is very important to be able to evaluate and predict performance of PPGs in porous media. In this paper, we will first introduce new class of enhanced PPGs designed for harsh reservoir conditions (high salinity and temperature) and then pr...

Low oil extraction and early high water production are caused in part by reservoir heterogeneity. Huge quantities of prevalent issues that happen older reservoirs. Polyacrylamide polymer gel systems have been frequently employed as plugging agents heterogeneous reservoirs to regulate output increase sweep efficiency. classified into three classes depending on their composition application condi...

Gel treatments are a proven cost-effective method to reduce excess water production and improve sweep efficiency in waterflood reservoirs. A newer trend in gel treatments uses particle gel (PG) to overcome some distinct drawbacks inherent in in-situ gelation systems. In this paper, we present a conceptual numerical model, based on laboratory tests and analyses, to simulate PG propagation throug...

Preformed particle gel (PPG, a kind of Super Absorbent Polymer) has been successfully applied to control conformance in around 2,000 wells in China oilfield. The paper summarizes: (1) why we proposed the method, (2) What are the properties of thermalstable PPG products, (3) where it has been used and how to select a good well candidate for a PPG treatment, (4) how to improve PPG treatment resul...
