Model for Fracturing Fluid Flowback and Characterization of Flowback Mechanisms

, 2014
A large volume of fracturing fluid that may include slick water and various sorts of additives is injected into shale formations along with proppant to create hydraulic fractures which define a stimulated shale volume a shale gas well will actually drain.

Numerical Simulation Of Horizontal Migration Of Proppant

, 2008
The horizontal migration of proppant was numerically investigated with a two-fluid model, in which the interaction between fracturing fluid and proppant, along with that among proppants was taken into account through interphase forces.

Practice and insights on CO2 pre-enhanced fracturing in deep coal measure gas reservoirs of Jixi Basin

Meitan kexue jishu
In response to challenges such as low permeability (0.006×10−15−0.066×10−15 m2), high breakdown pressures (up to 52.8 MPa), and difficult in fracture propagation in deep coalbed methane reservoirs of Jixi Basin, a novel CO2 pre-enhanced fracturing ...

Geomechanical Simulation of Partially Propped Fracture Closure and Its Implication for Water Flowback and Gas Production

, 2018
Summary Uneven proppant distribution is often encountered in hydraulic fracturing. Despite propped and unpropped fractures exhibiting different closure behavior during shut-in and early-flowback periods as a result of changes in effective ...
