Particle Plugging Test(The particle-plugging test (PPT) often is used to evaluate the ability of plugging particles added to a fluid to mitigate formation damage by stopping or slowing filtrate invasion into a core. ixtra)
Pressure Penetration Test(Shale Permeability using the Pressure Penetration Test (PPT). Pressure penetration technique (PPT) tests have been performed to investigate the effect of physical plugging by nanoparticles. Using this technique, we measure the permeability of shale samples in contact with various kinds of fluids: brine, base mud, and base mud with various concentrations of nanoparticles. ixtra)
Permeability Plugging Tester(The Permeability Plugging Tester (PPT), is a modification of the 500 ml high pressure, high temperature filter press. The instrument is used for making filtration tests on plugging materials without the interference of particle settling on the filter medium. ixtra)
