Polymer gels have been designed and successfully applied to improve sweep efficiency and
to reduce excessive water production by minimizing reservoir heterogeneity. Based on their …

Enhanced oil recovery (EOR) techniques can significantly extend global oil reserves once
oil prices are high enough to make these techniques economic. Given a broad consensus …

Unwanted water production is a serious issue in oil-and gas-producing wells. It causes
corrosion, scale, and loss of productivity. One method of treating this problem is to …

In recent years, polymer micro/nanogels which are re-crosslinked polymers with 3D
networks, have attracted a lot of interest in Enhanced Oil Recovery (EOR) field. In size of …

Branched-preformed particle gel (B-PPG) is a newly developed chemical agent for
enhanced oil recovery in heterogeneous reservoirs. In this paper, laboratory experiments …

High water production is a common problem in mature oil reservoirs. Gel-based treatments
have been widely used as blocking agents to control water production in heterogeneous …

Excess water production is a major problem that leads to early well abandonment and
unrecoverable hydrocarbon in mature oil fields. Gel treatments at the injection wells to …

Gel treatment is a cost-effective method for oilfield conformance control. Traditionally, in-situ
gels formed by the reaction of polymer and crosslinker at reservoirs have been used widely …

Pore-scale elastic microspheres were prepared controllably and their swelling property,
stability, and creep-recovery property in brine water were analyzed in laboratory. The goal of …

This paper provides a comprehensive review of the water control techniques that have been
applied in horizontal wells and presents the water control methods for wells of different …
