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 the performance of different polymer gel systems as an in-depth gel treatment using numerical simulation
… problems are called conformance problems and the treatment is called conformance improvement technologies (CITs). The aims of CIT is to correct the heterogeneity of the reservoir and to lower the unfavorable mobility ratio. These technologies are leading to the diversion of post-treatment water …

An Experimental Investigation of GLARE and Restructured Fiber Metal Laminates
… responses. Next, different metal surface pretreatment methods were explored. These included sandblasting, Phosphoric Acid Anodizing (PAA), and AC-130 Sol-Gel treatment. Woven S-2 glass, an epoxy adhesive, and aluminum alloy sheet metal were used to fabricate restructured FMLs using time and …

Polyacrylamide and its derivatives for oil recovery
… superior property on increasing viscosity and gelling ability in the presence of crosslinkers, polyacrylamides has become the primarily selection for polymer flooding and gel treatment agent in enhanced oil recovery. Recent developments, performance, applications and limitations of …

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 …

Screening guidelines and data analysis for the application of in-situ polymer gels for injection well conformance improvement
… economic and environmental impacts. Polymer gels have been effectively applied to mitigate water production and extend the productive lives of mature oilfields. However, selecting a proper gel technology for a given reservoir is a challenging task for reservoir engineers because of the …

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 …

Childhood Outcomes after Dextrose Gel for Treating and Preventing Low Glucose Levels in Babies
Oral dextrose gel effectively treats and prevents neonatal hypoglycaemia, but its long-term benefits and harms remain unclear. This thesis aimed to investigate childhood outcomes after oral dextrose gel to treat and prevent neonatal hypoglycaemia in late preterm and term at-risk infants. We updated …

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 …
