Paper presented at the 55th U.S. Rock Mechanics/Geomechanics Symposium, June 18–25, 2021
Paper Number: ARMA-2021-1917
... (water-wall and oil-wall) molecular interactions, which can result in the nanoscale effects of the boundary slip and the varying interfacial fluid viscosity, will make the fluid flow behaviors more complex and difficult to characterize. Additionally, the change in pore size due to the stress sensitivity...

Paper presented at the 55th U.S. Rock Mechanics/Geomechanics Symposium, June 18–25, 2021
Paper Number: ARMA-2021-1303
... ABSTRACT: Tight naturally fractured sandstone reservoir plays an important role in modern oil and gas development. However, it suffers from stress sensitivity damage due to well-developed natural fractures. To understand it, this paper introduced transient pressure pulse decay test (PDP...

... during testing. The velocity and permeability measurements of two types of shale were evaluated. Also the stress sensitivity coefficient of velocities and permeability were carried out. Our results showed that: (1) Longmaxi shale samples are much more anisotropic than Lujiaping shale samples. (2) Elastic...

Paper Number: ARMA-06-1070
... ABSTRACT: Cracks in a rock framework are known to have a large impact on the elastic wave velocities. It is therefore reasonable to assume that the stress sensitivity of the velocities to a large extent may be ascribed to stress induced changes in the population of cracks in the rock. Based...
