Abstract: Productivity in fractured wells typically declines when severe proppant embedment shrinks the fracture aperture and creates conductivity clogging fines. However, the mechanisms linking embedment to decline are poorly characterized. In the absence of this understanding,… read more here.

Abstract: Abstract Hydraulic fracturing is typically used to exploit underground gas/oil resources. However, most commercial fracture-design programs and reservoir simulators neglect proppant embedment issues when calculating hydraulic the fracture width, and the majority of previous studies… read more here.

DOI: 10.1021/acsomega.1c02407
Abstract: Hydraulic fracturing is often used to exploit unconventional hydrocarbons, and proppants are usually added during hydraulic fracturing to keep the fractures induced open. Nevertheless, time-dependent proppant embedment has often been neglected in previous studies. In… read more here.

DOI: 10.2118/204222-pa
Abstract: With the advancement of drilling and completion technologies in unconventional reservoirs, more extended reach wells are developed, and narrow-fracture environments are created in these reservoirs. Proppant embedment in monolayer/thin-layer-propped fractures can be significantly different from… read more here.
