Theory and Technology of Multiscale Dispersed Particle Gel for In-Depth Profile Control

Product Description Theory and Technology of Multiscale Dispersed Particle Gel for in-depth Profile Control systematically introduces concepts surrounding preparation principles and methods of DPG particles. The whole preparation process can be divided into two major stages: bulk gel crosslinking reaction period and DPG particle preparation period. The effects of bulk gel strength, shearing time, shearing rate and bulk gel-water ratio on PDPG particles are also systematically analyzed. Zirconium bulk gel, phenolic resin bulk gel, and organic-inorganic cross-linked bulk gel with short gelation time on the ground are introduced, along with gelation properties, gelation influencing factors, thermal stability and applicable conditions. This book systematically describes the theory and technology of multiscale dispersed particle gel which shows promise as an acceptable alternative to conventional water technologies needed for enhanced oil recovery in high water cut mature oilfields. Review Covers the use of polymer gel, an industry-recognized profile control agent that can decrease formation heterogeneity and enhance oil recovery From the Back Cover Theory and Technology of Multiscale Dispersed Particle Gel for In-Depth Profile Control systematically introduces the preparation principles and methods of DPG particles: an innovative technology that overcomes the drawbacks of traditional polymer gel in enhancing oil recovery in high water cut mature oilfields. The book fully covers the industrialized production process of DPG particles based on the successful lines established in China, outlining how these can be established in even complex construction environments such as the desert or sea. Specifically, three new technologies based on multiscale DPG particles, a soft heterogeneous compound flooding system, DPG strengthened polymer/surfactant combination flooding system, and three-phase foam, are detailed. The book also analyzes the in-depth profile control and displacement mechanism and synergy mechanism of these three systems. This book provides petroleum scientists and engineers, researchers in EOR, graduate-level petroleum engineering students, oilfield development scientists, researchers in reservoir physics, and others a practical handbook on this new technology.
