One of the best methods for the characterization of pore networks and their interaction with fluids is performing NMR rock core flow studies.
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 saturation.
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 a method to perform NMR flow studies. This 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.
When users are looking to pressurize the core, the P5 cell allows up to 5,000psi of confining pressure. This allows fluid to flow through the core sample at up to 5,000psi. These pressures are sufficient to replicate conditions found in most of today’s reservoirs.
We recommend using GIT Systems Advanced to maximize the information you can extract from your samples when conducting rock core flow studies. Information can be further enhanced by using a 3D NMR/MRI instrument like the GeoSpec 12 MHz and the Imacore 3017 coupled with our GIT Systems 3D imaging software. The 3D capabilities allow researchers to see how the fluid flows through the rock cores in real time.
