ResultThe laboratory conductivity tests at a proppant loading of 2 lb/ft 2 give a proppant pack height approximately half the height measured from the crush test (proppant loading 4 lb/ft 2). For example, at 40 MPa, the proppant height from the crush test is 10.97 mm for the mesh 40/70 Genoa sand and is 11.71 mm for the …

ResultSelection of proppant should not be solely on the proppant's crush strength at the applied stress value but should also depend on the proppant's overall integrity after being exposed to the reservoir conditions (Cinco-Ley et al., 1978). As sand beds become buried deeper, the temperature and stress levels increase, …

ResultA fracturing proppant whose bulk density is less than 1.5 g/cm 3 and apparent density is approximately 2.5 g/cm 3 can be regarded as a ULW fracturing proppant (Wu 2013).On the one hand, it can reduce the amount of guar gum used in the fracturing fluid, which reduces the damage to a reservoir (Cheng and Li 2006); …
ResultHydraulic fracturing, a highly efficient well-stimulation technique, can be utilised to significantly increase production from unconventional low-permeability rocks like shale. This is achieved through creating fractures in the formation by injecting a solution of water, sand, and chemicals. These fractures may make it …

ResultThe proppant made out of glass microspheres is another type of micro-proppants that its size is in a range of 10 to 46 μ m. The core of these borosilicate glass spheres is hollow; therefore, they have less weight than water. Their crush strength is 10000 to 18000 psi and they are commercially accessible.
ResultAbstract. This article describes a modified crush resistance procedure for testing proppant strength in an elevated temperature, aqueous (hot and wet) environment that better simulates downhole conditions. Frac sand, resin-coated sand, light-weigh ceramic, resin-coated ceramic and bauxite proppants were used …

ResultIn one patent, Smith et al. (2008) used lightweight metal to create a hollow metallic shell proppant. It possesses a high crush strength of at least 3000 psi with a density ranging from 0.6 g/cc to 2.5 g/cc. The high crush resistance and ductility of metals or metals alloy, instead of collapsing, caused the proppant to …
ResultAbstract. Crush resistance has become a key, perhaps even the singular, parameter used in selection of proppant for hydraulic fracture stimulation operations. The API Recommended Practice 19C (RP19C)—which is identical to the ISO13503-2 standard1— lays out procedures intended to produce repeatable …

ResultProppant crush tests are one method to determine some of these physical proppant parameters under in-situ conditions. Standardized crush test procedures are outlined in API RP-56, RP-58 and RP-60 and are summarized in ISO 13503-2. The intent of these tests is to provide a comparison of the physical characteristics …
ResultThe size range of the proppant is very important. Typical proppant sizes are generally between 8 and 140 mesh (106 µm - 2.36 mm), for example 16-30 mesh (600 µm – 1180 µm), 20-40 mesh (420 µm - 840 µm), 30-50 mesh (300 µm – 600 µm), 40-70 mesh (212 µm - 420 µm) or 70-140 mesh (106 µm - 212 µm). When …
ResultProppant crushing, a major proppant failure mechanism, occurs in geothermal energy and oil/gas stimulation production stages when the level of net stress exerted on the proppant exceeds the actual crush resistance of the material. Loss of effective reservoir conductivity due to proppant crushing can result in …

ResultOne major reason is the lower proppant loading, averaging 20% fewer pounds of proppant per foot than its brown and mixed sand wells. This may demonstrate why operators choose lower cost proppant, which means operators can use more proppant for less money, usually leading to higher production. …
