ResultParticle sphericity is a measure of how closely a proppant particle approaches the shape of a sphere. Charts developed by Krumbein and Sloss in 1963 are the most widely used method of determining shape factors. Clusters– Proppant grains should consist of single, well-rounded particles.

ResultAccording to the results, whatever the type of reaction medium, single ceramic proppant crush resistance decreases significantly compared with that of proppant exposed to a dry environment. With the increase of NaCl concentration from 0% to 10%, the crush resistance of the ceramic proppant reduced by 61.7%.

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); …

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 …

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. …

Result0 1. API 56/58/60 standardized testing was originally established by the American Petroleum Institute. API RP-56/58/60 testing standards were used to determine crush resistance of proppants used in hydraulic fracing or fracturing. In 2001, API and ISO members formed a group to create ISO 13503-2, the current standard …

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).
