... in the past decades, however, in recent years, thermosetting gels gained industry attention due to their superb physical characteristics. Those characteristics opened the door not only for great innovative applications but also making operations quicker and safer. This article delves into the practical...

... out to examine how a special methyl methacrylate-based gel, modified to react to CO 2 , behaves and functions in carbon capture areas. The experiment looked at how much the gel expanded over time using laser profilometry to measure its growth under various conditions. The study also measured the gel's...

... at the platform without impacting ongoing production from several other infield producers at the same time, or export quality after subsequent passage through the platform's process system. A crosslinked gel train was the concept selected for the pipeline system decommissioning from subsea to subsea. Due...

... Abstract Preformed particle gels (PPG) have been widely applied in oilfields to control excessive water production. However, PPG has limited success in treating opening features because the particles can be flushed readily during post-water flooding. We have developed a novel micro-sized Re...

...-induced fracturing, and thief zones trigger water channeling. Conformance polymer-gel squeeze is common for alleviating channeling. With sufficient gel (10-25% of channel volume) selectively placed into water-bearing channels, injected water is effectively redistributed to improve sweep efficiency...

... Abstract Preformed Particle Gels (PPGs) have been widely applied to control excessive water production in mature oil fields with fractures or fracture-like features, especially in sandstones, but with limited attention to carbonates. However, a vital concern arises regarding the potential...

... 250°F. With this system, viscoelastic gel viscosity was maintained without degradation for over 18 hours at 250°F, and the fluid showed rapid shear recovery throughout. Decreasing the average alkyl chain length on the surfactant reduced the maximum working temperature of the resulting viscoelastic gel...

Control of the smart gel particle size distribution was demonstrated through batch synthesis experiments. Microfluidic experiments show some...

... demonstrate a good correlation between low shear viscosity and proppant transport capability. Static and dynamic proppant transport data were used to design viscous slickwater to replace linear gel. The friction reducer has been successfully applied in the field in more than 3,000 stages. Formations that were...

... Abstract Disproportionate permeability reduction (DPR) is a phenomenon whereby many water-soluble polymer solution and polymer gels reduce the permeability to water flow more than to oil or gas flow. DPR is important for some gels that are applied to production wells in water-shutoff treatments...

... gel, and more rapidly in linear gel than in crosslinked 30 pptg guar gel. Therefore, variations in the fracturing fluid can control the swelling of particles, a factor that can be used to “place” the diverter material deep in the fracture for far-field diversion, or closer to the perforations for near...

... In this work the polymer microgel dispersions are tested for ease of placement into cement-walled fractures and gel strength in holding back pressure after the reaction with cement. Laboratory experiments involved injecting various unswollen polymer microgel dispersions (typically starting at pH...

... Abstract Fracture fluid damage caused by residual polymer gel in propped fractures results in low fracture conductivity and short effective fracture length, sometimes severely reducing the productivity of a hydraulically fractured well. The residual gels are concentrated in the filter cakes...

Gel pigs have also other applications in pipeline systems: isolation (sealing) of pipeline section under pressure, carryover of gas and water accumulations, pulling of the devices that got...

... Abstract High pH borate gels have been used in fracturing deep gas reservoirs in Saudi Arabia. Guar and hydroxypropyl guar are used at various concentrations up to 45 lb/1000 gals. A breaker (regular or encapsulated oxidizers, guar-specific enzyme, or combinations of these breakers) is usually...

Generally, viscous mud pills with lost circulation materials and gels or cement plugs are placed to allow plugging of loss circulation zone. But in case of total circulation loss...
