... was measured by core holder system and a Darcy's set up. Because of the very low permeability matrix, the measurements were repeated with another Hassler sleeve type core holder. Oil and gas relative permeabilities were measured experimentally by the unsteady state method (figure 2). The porosity of models...

... attempts to answer some of these questions by conducting some specially designed depletion tests. TESTING MATERIAL AND EQUIPMENTS A schematic diagram of the pressure depletion test setup is illustrated in Figure 1. The test sand was packed inside a core holder of 41.2 cm in length and 3.8 cm...
