Stress Amplification and Arch Dimensions in Proppant Beds Deposited by Waterfracs

, 2010
Summary Equations and a procedure have been developed to calculate the excess stress induced on a proppant dune that is deposited by a waterfrac with poor proppant-transport characteristics. This method also calculates the dimensions of an

Proppant Performance in Marcellus Shale Fractures Under Experimental In-Situ Stress Conditions

, 2018
Hydraulic fracturing is a key treatment for economical production from shale formations. High surface pressure is used to fracture the formation, and proppant is pumped to prevent fracture closure after the pressure is removed. The ability of proppant to

Impact of rock lithology and microstructural properties on proppant embedment and fracture conductivity: A case study of the Caney Shale, Southern Oklahoma, USA

, 2022
A key feature of shale reservoirs is their low level of permeability. As a means of producing these reservoirs in a cost-effective manner, there is a requirement to create hydraulic fractures with highest level of conductivity, but these fractures are ...
