Study on the Influence of Bottom Hole Confining Pressure on High-Pressure Jetting Techniques

Shiyou jixie, 2021
As the development of oil and gas resources continues to deepen, the impact of bottom hole confining pressure on high-pressure water jetting has become more and more prominent. To compare the rock-breaking performance of high-pressure water jet under the

Effects of confining pressure, pore pressure and temperature on absolute permeability. SUPRI TR-27 [PDF]

, 1981
This study investigates absolute permeability of consolidated sandstone and unconsolidated sand cores to distilled water as a function of the confining pressure on the core, the pore pressure of the flowing fluid and the temperature of the system.

Permeability evolution during progressive development of deformation bands in porous sandstones [PDF]

, 2003
Triaxial deformation experiments were carried out on large (0.1 m) diameter cores of a porous sandstone in order to investigate the evolution of bulk sample permeability as a function of axial strain and effective confining pressure. The log permeability
