Measuring relative permeability to steam in cores of water and oil containing reservoir formations
A process is described for determining permeability properties of at least one fluid of the group consisting of steam, water and oil in a sample of reservoir rock formation containing fluid phases inclusive of at least oil and water phases. The process comprises: providing a core of the reservoir formation containing oil and water; mounting the core within a flexible walled, impermeable, tubular sheath means arranged for flowing fluid through the core; and mounting the flexible walled core-containing means within a relatively rigid walled container having fluid impermeable walls which are permeable to X-rays and pressurizing the core within the rigid walled container to a pressure approximating that of the reservoir formation.
