I-SW Apparatus

Overview:
The I-Sw apparatus is an automated system designed for determining the Resistivity index by pressure equilibrium or constant injection method.  The system allows for direct resistivity measurement across the core sample under in-situ conditions while injecting oil or bine at rates as low as 1.4E-5 CC/min. The core holder and pumps confining, injection and return are placed in an incubator for isothermal conditions (40°C). The core holder is designed for 1”OD x2” & 1.5” OD x3” samples for confining pressure up to 10,000 psi. The I-Sw system is built to meet R&D standards and is a completely automated testing apparatus.
