Preformed Particle Gel for Conformance Control
نویسنده
چکیده
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 results, (5) what lessons we have learned from the field applications, and (7) how to improve the current technology for better conformance control results.

Performance Evaluation of Viscosity Characteristics of Enhanced Preformed Particle Gels (PPGs)
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...

Preformed particle gel (PPG) has been successfully synthesized and applied to control excess water production in most of the mature, waterflooded oil fields in China. This paper reports on laboratory experiments carried out to investigate PPG transport mechanisms through porous media. Visual observations in etchedglass micromodels demonstrate that PPG propagation through porous media exhibits s...

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...

: Unwanted water production from oil and gas reservoirs is a serious problem for producers. Preformed particle gel (PPG) treatment is a benefit approach to control excess water production. Swelling percentage of PPG samples in saline water is a key factor affecting the efficiency of the water conformance process. In this study, an efficient series of PPGs were synthesized and their swelling beh...
