Degradable nanocomposite preformed particle gel for chemical enhanced oil recovery applications
… first product is a degradable nanocomposite preformed particle gel for enhanced in-depth mobility control. Three different types of degradable nanocomposite preformed particle gels were synthesized. These three nanocomposite hydrogels were made using Laponite XLG, Calcium Montmorillonite, and …

Evaluation of recrosslinkable preformed particle gel (RPPG) as a fluid loss control material during drilling operations
… a comprehensive evaluation of a re-crosslinkable preformed particle gel (RPPG) has been conducted to determine the extent to which it can be used to control drilling fluid losses during drilling operations. The RPPG consists of swellable gel particles that can self-crosslink to form a strong bulk …

Comprehensive evaluation of a novel EOR method-coupling low salinity water flooding and preformed particle gel to enhance oil recovery in fractured reservoirs
… is often low due to areal heterogeneity. Gel treatments have proven to be a successful and inexpensive fluid diversion method when used to plug the thief zones and thereby improve sweep efficiency in reservoirs. However, particle gel treatment can only be used to plug fractures or high …

Investigation of Recrosslinkable Preformed Particle Gels for Natural Gas Conformance Control
<p>"Recross linkable Preformed Particle Gel (RPPG) is a novel type of preformed particle gel in which particles can bond together to form a strong bulk gel system after being placed in the target formation. In this research, I systematically evaluated the feasibility of using this product to …

Plugging performance of preformed particle gels in fractures and its influencing factors
"Preformed particle gels (PPG) has been successfully applied to combat the water channeling caused by fractures or fracture-like channels. Understanding the placement and plugging of PPG in fractures is crucial for gel treatment design. The objective of the dissertation is to explore the plugging …

Numerical simulation study of gel treatment for conformance control from lab to field
<p>“Gel treatment has been widely applied to control reservoir conformance and thus improve the sweep efficiency of injection fluids. Quite a few numerical simulations have been conducted to investigate the factors impacting gel treatment and assist to optimize treatment design and predict the …

EVALUATION OF NOVEL PREFORMED PARTICLE GELS FOR CONFORMANCE CONTROL AND ACID STIMULATION THROUGH CORE FLOODING TESTS
… systematically evaluates two newly developed gels: Degradable Preformed Particle Gel (DPPG) and Re-crosslinkable Preformed Polymer Gel (RPPG). DPPG is designed to be a temporary plugging agent for acid stimulation and can self-degrade into a water-like fluid. RPPG is designed for reservoir …

Fundamentals of Microgel Flooding and Nanoparticles-Stabilized Foams in Enhanced Oil Recovery
… enhanced oil recovery (EOR) technologies, preformed particle gel (PPG) treatment and foam flooding are commonly used and can both effectively improve the sweep efficiency. The performance of these EOR technologies depends on a number of geometrical, materials, and flow properties that can …
