Experimental analysis of proppant stimulation effectiveness in sand fracturing

Hydraulic sand-fracturing experiments are conducted at different proppant content and fracturing fluid viscosities on samples obtained from the shale reservoirs in the Guanyinqiao Member. The characteristics of the obtained sand-fracturing curve and proppant distribution are investigated. The test r...

Summary:Hydraulic sand-fracturing experiments are conducted at different proppant content and fracturing fluid viscosities on samples obtained from the shale reservoirs in the Guanyinqiao Member. The characteristics of the obtained sand-fracturing curve and proppant distribution are investigated. The test results establish that the fracture morphologies and proppant distribution after sand fracturing have significant differences. Although the proppant is favorable for increasing the fracture width, the fracture width does not increase gradually with the increase in proppant content. For both acoustic emission localization and proppant distribution, the sand fracture effect is best at a proppant content of 10%.
