The CFS machine is useful for the oil and mining industry. Rock core samples are able to be placed under pressure and temperature conditions, akin to those found deep underground, during the mining process, and is suitable for testing USS water and gas floods.

The PMI Cylindrical Core Cutting Machine is custom designed for vibration-free cutting of unconsolidated core (frozen or stabilized at ambient temperature). The saw/blade configuration is designed to cut a variety of inner barrel or liner types including PVC, ABS, aluminum, fiberglass and cardboard. The saw features 24" diameter wheels for reduced blade stress, a 24" throat for cutting materials up to 12" thick, an onboard welder for immediate and cost effective blade repair, and a table frame for stability.

The PMI Automated Core Saturator is a completely automated system that can use various algorithms for proper saturation of multiple core samples using a vacuum to remove trapped air, and pressurizing pumps to make sure the cores are completely saturated, pressure pump can control pressurizing rates precisely and maintain pressures to within a 0.2% tolerance. The Windows based program provides totally automated execution of the test, data aquisition, data storage, and data management are all performed by the user-friendly software. Operator involvement is minimal and the robust machine requires a minimal amount of care.

The rock core sample is loaded in a holder and confining pressure is applied. The system is then charged with test gas to the desired pore pressure. Adequate time is given to allow this pressure to fully saturate the sample. After reaching equilibrium the upstream and downstream portions of the system are isolated from each other. A pulse is then created by raising the upstream pressure (or lowering the downstream pressure). Data is recorded throughout this process and is used in conjunction with known system volumes to calculate gas flow rates and permeability. The equipment is fully automated. Execution of the test, data acquisition, data storage and data management are all carried out by PMI Software. Operator involvement is minimal, and the instrument is robust and requires a minimal amount of care.
