Due to the difficulties in plugging high-pressure injection wells, the short period of plugging, and the use of modified nano-silica, a novel chemical gel plugging agent has been created. Modification of silica using silane coupling agents, and using the aqueous free radical polymerization method synthesized chemical plugging agent with AM, AA, and DMDAAC. The optimum synthesis conditions were screened by single-factor analysis: mass ratio m(AM):m (AA):m(DMDAAC) = 8:1.5:1, modified nano-silica concentration of 1.0%, total monomer mass concentration of 8.0%, initiator concentration of 0.3%, the cross-linker concentration of 0.4%, and coagulant concentration of 0.6%. The performance of the chemical plugging agent was evaluated under the target oil formation conditions. The experimental results showed that the chemical plugging agent exhibited good temperature resistance at 40-100 C, good salt resistance at mineralization (0.5-2.5) Â 10 4 mg/L, and the chemical plugging agent breaks through pressure gradients of 1.12, 15.42 and 90.15 MPa/m in the wellbore, fracture and core, respectively, compared with most gel plugging agents, this plugging agent is more suitable for sealing with pressure work. After adding the breakout agent, the fluid after breakout is fluid-like with low viscosity, which is convenient for reverse discharge and will not cause harm to the reservoir and ensure the subsequent normal construction operation.

“…Today’s world is moving toward a sustainable economy, where the operations must be powered by sustainable sources by curbing the reliance on sources that cause severe environmental damage. Natural gas can play a crucial role, and the market for natural gas is predicted to rise exponentially in the upcoming years. , Unconventional hydrocarbon gas resources must be relied upon to mitigate potential energy crises. − The most conservative estimations state that the carbon reserves in gas hydrates worldwide are at least twice that of all other fossil fuel-based reserves. Gas hydrates structures, lately called zeolitic ice, are composed of 85% water, making them most similar to ice .…”

Natural gas hydrates are unconventional abundant hydrocarbon energy resources that can guarantee energy sustainability with little environmental impact. The solid nature of the resource, distinct thermodynamic characteristics, and accumulations at shallow depths make the existing conventional production techniques unviable. Among all the currently explored production techniques, the hydrate-based carbon capture and sequestration (HBCCS) technique is expected to improve production, proven to be geomechanically safer, and conceptualized to be environmentally friendly. In this carbon-neutral production concept, carbon emissions are effectively sequestered for the long-term. This review presents a comprehensive overview and perspective of the CO 2 exchange-based approach to extract methane (CH 4 ) from naturally occurring gas hydrate reserves, emphasizes its prospect as a suitable alternative according to the current energy demands and climate concerns, establishes its environmental and production challenges, and demonstrates the recent developments. This review focuses on the production aspect and discusses the mechanism of the exchange process, experimental and modeling studies, various in situ production tests using different techniques on multiple sediments, and production challenges associated with the exchange process. The aspects of geomechanics and possibilities of fracturing in hydrate reservoirs are also discussed elaborately. A suitable and effective technique is yet to be established to produce natural gas commercially by addressing the existing challenges like sand production, seafloor stability concerns, marine ecosystem problems, low production rate, uncontrolled dissociation, water production, etc. Although the CO 2 exchange-based method is thermodynamically favorable, rapid crystallization of CO 2 restricts mass transfer and prevents continuous exchange. The exchange process is also influenced by heat, salinity, residual water saturation, exchange gas composition, injection phase, injection pressure, sediment properties, etc. There is a need to study the CO 2 −CH 4 exchange process at a fundamental level and at a larger scale, to understand its intricacies. In tandem with comprehensively discussing the subject, this review has listed the issues that require tenable solutions, which shall be helpful to readers who wish to work on production from CH 4 hydrates using the CO 2 exchange process. Methane hydrates shall be one of the strategic energy sources to meet our growing energy requirements for a sustainable future.

“…The well modeling software PROSPER is designed to assist in making sure that well models are accurate and consistent. It also allows the handling of every aspect of well modeling, PVT (fluid description), VLP correlations (for calculating flow-line and conduit pressure loss) and IPR (reservoir inflow) [1]. PROSPER has different ways of matching PVT, point flow correlations and IPR Mater.…”

“…The options, PVT data, equipment data, IPR data and calculation outline are all on the main PROSPER screen, which is divided into five parts. When PROSPER is used to make well models, the concept of integrated production modeling IPM is used [1]. PROSPER is the link between the reservoir model and the surface model in well modeling.…”
