Abstract Lightweight, intermediate-strength proppants have been developed that are intermediate in cost between sand and bauxite. A wide variety of proppant materials is characterized and compared in a laboratory fracture conductivity study. Consistent sample preparation, test, and data reduction procedures were practiced, which allow a relative comparison of the conductivity of various proppants at intermediate and high stresses. Specific gravity, proppants at intermediate and high stresses. Specific gravity, corrosion resistance, and crush resistance of each proppant also were determined. pr

Hydraulic fracturing is a key stimulation technique for enhancing the productivity of tight sandstone reservoirs, with the conductivity of propped fractures serving as a critical parameter for evaluating stimulation effectiveness. This study investigated the conductivity behavior of propped fractures through laboratory experiments using commonly used oilfield proppants. The effects of proppant size, type, concentration, and proppant combination on fracture conductivity were systematically evaluated. Results show that at low closure stress, conductivity differences among various proppant types

The use of proppants in hydraulic fracturing has significantly grown worldwide in recent years. Discoveries of large unconventional reservoirs in the north of Brazil have collaborated to give it the 10th position among countries with the world's largest shale reserves. Nowadays, studies on nanomaterials that are used as additives in proppants are the focus of North America's companies and universities in order to develop either proppants that can suffer mechanical and chemical changes inside the reservoir or that enable their traceability and direction.

Proppant is one of the key materials for hydraulic fracturing. For special situations, such as middle-deep reservoirs and closure pressures ranging from 40 MPa to 60 MPa, using a single proppant cannot solve the contradiction between performance, which means crushing rate and fracture conductivity, and cost. However, using combined proppants is an economically effective method for hydraulic fracturing of such special reservoirs. Firstly, for different types, particle sizes, and proportions of combined proppants, various contact relationships between proppant particles are considered. The rando

AbstractIn this study, the mullite-quartz-based proppants were successfully prepared by using the coal gangue as the raw materials. Then, the effects of the additive and the sintering temperature on the composition, microstructure, and properties of the proppants were investigated. Results showed that the proppants sintered at 1250°C with the 10 wt% bauxite additive presented the best performance, which was very close to that of the quartz-proppant, and met the operational requirements of the 52 MPa coal bed methane wells.

Taking commonly used ceramic particle supports as the research object, the problem of difficult hardness detection caused by the macroscopic morphology of ceramic particle supports was solved by optimizing the pre-treatment sample preparation method; Using the method of controlling a single variable, the specifications (mesh size) and origin of the ceramic particle support agent were changed separately.

Spherical particles based on bauxite-type raw materials, commonly referred to as proppants, are state-of-the-art for particle receivers of concentrated solar power plants. Particles are heated in a fluidized reactor by focused sunlight and are transported to a heat-exchanger or a storage tank. Therefore, key properties for absorber particles are high solar absorptance and mechanical endurance. Due to their relatively poor content of color-giving transition-metal cations, bauxite-derived proppants show limited solar absorptance, which is even deteriorating by long-term heat exposure.

Workers involved in hydraulic fracking processes are exposed to various types of chemicals and dusts in their workplaces, such as proppants, which hold open the fissures created in the fracking process. Recently, ceramic proppants have been developed that may be less hazardous to workers than traditional proppants. Pulmonary function testing of workers producing ceramic proppant was used to assess the potential inhalation hazards of ceramic proppant.

ABSTRACT: This paper proposes a new low-density, high-strength composite proppant to address the rising cost of proppants in hydraulic fracturing operations in tight oil reservoirs. Fly ash and coal gangue are sintered with a certain concentration of bauxite and alum at 1300°C∼1500°C to form a composite proppant. Results from X-ray diffraction (XRD) and scanning electron microscope (SEM) analyses show comparable strength between ceramic and composite proppants. Although the conductivity of new composite proppants is 15% smaller than ceramic proppants after 150 h of experiments, their strength

Abstract The long-term sustainability of fracture conductivity in a geothermal system using proppant will be affected by crushing pressure and geothermal fluids. Previous experiments have shown that for short-term periods, field testing results have indicated some performance improvements and a few experiments for long-term periods have shown that different types of proppants and the crushing test results suggest probable geomechanical degradation of the proppants under the test conditions. So, some proppants, such as ceramics and kryptospheres, showed a significant degree of mechanical streng

ABSTRACT: To investigate the impact of surface roughness on proppant crushing and its effect on fracture conductivity in Shale Gas Formations, laboratory conductivity experiments were performed on standard core columns drilled along hydraulic fractures. The morphology of proppants within the fractures was observed using computed tomography (CT) and scanning electron microscopy (SEM). The results indicate that the roughness of the fracture surface has a greater impact on ceramic proppants than on quartz sand in terms of crushing rate.

ABSTRACT During hydraulic fracturing operations, proppants were usually pumped in a small-diameter, medium-diameter, and large-diameter sequence. Thus, the hydraulic fracture was propped by different size and types of proppants. It is found that the slurry operation parameters such as fluid viscosity, sand-slurry ratio, and pump rate could affect proppant migration and settlement in the fractures. It is crucial to evaluate the conductivity of these propped fractures while considering the migration and placement of proppant size and types. This paper proposes practical dynamic fracture conducti
