Abstract
This thesis reports on research on multiphase flow in porous media using a nuclear tracer technique for measurements of local fluid saturation distributions during core displacement experiments. The thesis presents the radioactive imaging technique, and the development, design and construction of the equipment needed for imaging long-core flood displacements are documented. The equipment has been automated and the instrumentation and data processing are described. Further, a documentation of the application of the equipment is presented, with emphasis on studies of basic parameters governing the fluid flow through porous media. The experimental developments also include the construction of a vertical flow-rig, operating with the nuclear tracer technique. This apparatus is designed for studies of gravity effects on petroleum recovery, but has been further developed to also being capable of scanning in two directions, introducing the possibilities for two dimensional imaging. The phenomenological studies adress both miscible and immiscible displacements, but emphasis has been on two phase immiscible displacements. Water injection during secondary recovery and the impacts by varying the various reservoir parameters have been evaluated. However, also tertiary recovery has been investigated, especially with respect to surfactant injection. The thesis includes studies of the effects of interfacial tensions, both in chemical
