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 …

Reducing water production from hydrocarbon wells is one of the major requirements to
prolong the life span of production wells. Gel treatment is commonly regarded as one of the …

Abstract Preformed Particle Gel (PPG) surfactant combined flooding, designed to
simultaneously improve the sweep efficiency and displacement efficiency, has emerged as a …

The field of microemulsion-assisted conformance improvement technology (ME-CIT)
requires workflow planning in order to effectively decrease the water-to-oil ratio during …

The injection of preformed particle gels (PPGs) is one of the novel solutions to improve
conformance control in mature waterflooded reservoirs. In this method, the interaction …

The heterogeneous phase combination flooding (HPCF) system which is composed of a
branched-preformed particle gel (B-PPG), polymer, and surfactant has been proposed to …

The combination of microsphere and SmartWater injection is a novel method to increase oil
recovery in carbonate reservoirs. This work developed a two-phase and multi-component …

Summary 40% to 50% STOIIPs remain in the subsurface after polymer flood, characterized
by highly scattered remaining oil distribution. Currently, most discussed measures regarding …

The application of microemulsion-assisted conformance improvement technology (ME-CIT)
has the potential to significantly reduce the water-to-oil production ratio and operational …

Traditional polymeric microsphere has several technical advantages in enhancing oil
recovery. Nevertheless, its performance in some field application is unsatisfactory due to …
