Ceramic fracture proppants are extensively used for enhancing the recovery of fossil energy and geothermal energy. Previous work has reported attracting-oil-repelling-water (AORW) property oil-wet at faces fractures. Because lack a method measuring contact angle proppant packs, terms water-wet were defined based on observations liquid droplets surfaces packs without quantitative measurement. An...

Abstract Proppant crushing and embedment in hydraulically-induced fractures is a major drawback to the recovery of unconventional oil/gas geothermal energy production. This study provides grain-scale analysis fracture evolution mechanisms proppant crushing, rock damage during embedment, influence realistic reservoir/fracture fluid on behaviour packs subjected in-situ stresses using discrete ele...

This paper investigates proppant flow and transport in intersected fractures at angles typical for intersections of pre-existing new hydraulic fractures. Proppant is small granular material, which placed into during geothermal hydrocarbon reservoir stimulation props the fluid paths open exploitation. study uses plexiglas laboratory slot experiments enhanced with advanced image analysis identify...

Injecting proppant to prop open fluid-driven fractures in subsurface reservoirs is one of the key missions hydraulic fracturing. However, quantitative evaluation distribution successfully propped limited due infeasibility direct measurement. This work defines an indexing parameter for field practice estimate proportion proppant-filled reservoir – filling index (PFI). A new data-driven workflow,...

■ Compressor for dust collection in silos The automated stimulation delivery platform automates and streamlines surface operations, resulting in a smaller footprint, increased efficiencies, and reduced NPT. A combination of bulk material delivery and storage systems, equipment designed for continuous operations, automated processes, and accurate inventory management enables more-efficient, reli...

Abstract During hydraulic fracturing treatment, huge quantities of gel are pumped into the formation to initiate fracture, maintain it open and transport proppant. The fracture dimensionless conductivity (Fcd) is a key parameter optimize design, estimate productivity Index (PI) folds increase (FOI). However, these parameters affected by residues which decrease conductivity; thus, proppant clean...

In the case of fracturing reservoirs using fluids, size damage to proppant conductivity caused by treatment fluids is significant, which greatly influence effective execution hydraulic operations. The fluid should be characterized minimum a fracture filled with proppant. A laboratory research procedure has been developed study effect foamed and non-foamed in fractures material. paper discusses ...

Generally, huge amounts of fracturing fluid are used in a shale gas well but the flowback efficiency is low. Since distribution characteristics imbibed complex, they need further evaluation. This paper takes Longmaxi Shale as research object, including matrix cores, natural fracture cores and artificial with proppant. Stress sensitivity experiments carried out on above three kinds under differe...

Abstract Proppant embedment mainly accounts for diminishing fracture aperture and conductivity. The conductivity decrease could greatly restrict fluid flow, thereby affecting the well performance. In this paper, new mathematical models are derived to calculate proppant after hydraulic fracturing. These take three crucial factors into consideration, including instantaneous elastic deformation, c...
