The TrueCrush™ test is a new, patented testing procedure for determining the actual performance of a proppant used in hydraulic fracturing. In contrast to the API Crush Test, the .The API test classifies a proppant according to the stress at which < 10% fines is generated; for example an API 7k proppant would produce < 10% fines at 7000 psi. A PT Crush Profile (see .2. API Crush Test 2.1. API Crush Test Procedure: API Standard 19C 1. Sieve Analysis: A sieve analysis is performed to precisely determine the size range of the proppant sample. For 40/140 mesh sand, a set of sieves including 40, 70, and 140-mesh sieves is used to filter out sizes 40-mesh and larger and sizes smaller than 140-mesh. 2.
The sphericity and roundness of the proppant significantly affect the proppant crush resistance and conductivity. The higher the sphericity and roundness, the better the proppant crush resistance and conductivity. This is attributed to the wider distribution area of stress (Economides, 2009; Kamat et al., 2011; Zoveidavianpoor and Gharibi, 2016). “The API Crush Test determines if a proppant sample with a specific size range (i.e. 40/140) responds to a specific pressure (i.e. 8000psi) in such a way that 90% of the proppant sizes in this given size range is still .
Proppant Crush Testing: The Pitfalls of the Standard API 19C
The new proppant crush test approach was used to compare the strength of 40/70 sand, 40/70 resin coated sand, 30/50 sand, and 30/50 resin-coated sand. The failure stresses for the above proppants . The “Proppant crush-resistance test” is described in a 5-page layout i n section 11 of RP19C (American Petroleum . Institute 2008). That procedure can be summarized as follows: Sieve .
The TrueCrush™ test is a new, patented testing procedure for determining the actual performance of a proppant used in hydraulic fracturing. In contrast to the API Crush Test, the TrueCrush procedure determines the strength of the entire proppant. This yields a result that gives comparable data for: The proppant properties were evaluated using data obtained from a modified crush test. The grain shape before the test, the grain breakage pattern, the stress-strain response of the proppant pack, and the change in particle-size distribution caused by compressive stresses of up to 40 MPa were measured. In addition to considerations of fracture conductivity, there are several other issues that must be addressed when selecting the appropriate proppant for use in multistage fractures, including flow convergence in transverse fractures, proppant transport when low-viscosity fluids are employed, and proppant crush at typically low concentrations.The crush resistance test is performed by crushing a sample of proppants under increasing stresses. The highest stress level (rounded down to the nearest 1000 psi) under which the proppants generate no more than 10% crushed material is defined as the crush resistance (sometimes called the K-value).The higher the crush resistance is, the better the proppants are.
impact test symptom scale
The sieve distribution of the generated fines in crush test suggests that the mechanism of decreasing fines generation compared to uncoated samples is due to a strength increase, not to a stress distribution as observed in the case of resin-coated proppant, where the polymer diffuses the stress, resulting in larger broken particles that are . This paper will look at the evolution of the Proppant Crush Test and perform a deep dive into the API 19C method, exploring inconsistency of results between 3 rd party laboratories, possible causes of the inconsistency, and how that impacts proppant of different gradations.. While there are many varying grades of proppants which are utilized in hydraulic .Wabash MPI is proud to introduce Model G28-12-PCR proppant Crush Test press. This Genesis Series press meets the critical demands of ISO 13503-2:2006 with unsurpassed cycle repeatability. The proportional hydraulic system is capable of applying a constant rate of 13.8 MPa/min. (2000 PSI min.) from 2 ton to 28 ton clamp force within a ±2.5% . When the American Petroleum Institute (API) established standardized crush-testing procedures (API RP-56 1983), the committee indicated that the test results should "provide indications of the stress level where proppant crushing is excessive and the maximum stress to which the proppant material should be subjected."However, over time, many have .
The API test classifies a proppant according to the stress at which < 10% fines is generated; for example an API 7k proppant would produce < 10% fines at 7000 psi. A PT Crush Profile (see example below) can show graphically how median particle diameter (MPD) can vary with changes in closure stress.

We propose a watershed-based unsupervised algorithm for segmentation of proppant particles, as well as a set of parameters for the characterization of .
Proppant Crush Test: A New Approach
As per standard American Petroleum Institute (API) requirements [2], a proppant grains crush test should be performed at an axial stress of up to 100 MPa (15,000 psi). The conventional approach to measuring the percentage of grains crushed during the test is based on sieving and weighing. In this work, algorithms for an image-based assessment . Crush resistance is important because fewer proppant particles with greater crush resistance will be crushed under the same closure stress of the fracture to generate tiny particles referred to as “fines” blocking the open pathways for hydrocarbons to travel through the packing . The tests and test apparatus herein have been developed to .
