P5 and P10 Cells for Overburden Studies
Make Overburden Studies Routine

GeoSpec

Nuclear Magnetic Resonance (NMR) is a valuable tool for both routine core
analysis and SCAL. Most measurements are made at ambient temperatureand pressure, but it is becoming increasingly important to carry out
measurements at as close to reservoir conditions as possible. To do this, anNMR-compatible core holder is needed, but existing designs have severe
limitations on either sample handling or NMR performance.
The P5 and P10 Overburden Cells remove these limitations
and allow users to carry out NMR measurements at reservoirconditions. Designed and built with a focus on usability andperformance, the cells allow users to pressurise samples withup to 10,000 psi of confining pressure (for 1” cores) or 5,000psi (for 1.5” cores). The P5 and P10 Overburden Cells, uniqueto the GeoSpec range of NMR rock core analysers, use stateof-the- art materials to allow the NMR coil to be closer to thesample while maintaining the performance of the GeoSpec.

P5 Cell in its benchtop standUnique features of the P5 and P10 Cells:
The cells take full advantage of the industry leading
performance of the GeoSpec range of instruments, as theonly pressure vessels specifically designed with Q-Sense
technology. Q-Sense delivers short echo spacings and highsignal-to-noise ratios, leading to improved measurement of• Can be held at pressure outside the instrument•	Allow quick loading/unloading of samples
through the twist-lock lid•	Low background signals for effective

fluids in smaller pores, maximising the cells’ ability to performmeasurements on low volume samples suchmeasurements on tight rocks from unconventional reservoirs.

as shales• Multiple levels of safety protection•	NMR coil embedded in the cell - allowing fasterand more accurate measurements.

No longer does one sample monopolise the NMR instrument for days or weeks. TheP5 and P10 Cells allow the sample to be pressurised both inside and outside the instrument.
Pressurised samples can be inserted and removed from the instrument without depressurising,eliminating pressure cycling issues. The cells are designed with pressure fittings at the top andbottom, allowing users to perform pressure flow studies.
The safety of the user is our highest priority. The P5 and P10 Cells utilize a secondary
containment system providing unprecedented protection in a pressurised environment.
Each cell is CE certified and tested to ensure the highest quality and safety standards are met.
