Abstract
As the market for fracture stimulation emerges internationally, selecting the proper proppant is essential. Comparing data from different proppants can aid proper selection for particular reservoir applications. Correlations between the test data can be used to forecast the proppant behavior inside the formation.
API and ISO standards were used for qualifying tests, such as specific gravity (SG), bulk density, acid solubility, turbidity, sphericity, roundness, sieve analysis, crush strength, and long-term fracture conductivity. The significance of each test is discussed, the results are compared, and correlations are developed. Each test has been weighted, and a scoring index is provided to demonstrate how the quality of proppant should be considered to help select the optimum proppant.
This work provides insight into proppants manufactured in different regions in the eastern hemisphere. The characterization of different proppants from the tests performed reflects how different local sourcing options can impact proppant quality. The scoring index can be used as a quick guide for the preferred proppant selection for a specific well stimulation.
