One of the best methods for characterization of pore networks and their interaction with fluids is performing an NMR flow study. These studies involve using a pressurized vessel within the NMR or MRI instrument to flow fluid at pressure through the core sample while scanning the core with the instrument. The scans provide images of the fluid flowing through the core and can provide a lot of information about wettability, pore throat size, pore volumes, relative permeability and saturations.
Flow studies are a key measurement technique for those researching and performing enhanced oil recovery (EOR) studies.
The P5 cell for Overburden Studies provides GeoSpec Rock Core Analyzer customers with an easy to implement method to perform NMR flow studies. The P5 cell was designed and built by the manufacturer of the GeoSpec product line, Oxford Instruments, so it allows the user to continue to utilize the high performance of the instrument while performing flow studies.
The P5 cell allows users to apply up to 5,000psi of confining pressure on the core, and then flow fluid through the core sample at up to 5,000psi. These pressures are sufficient to replicate pressures found in most of today’s reservoirs.
