HPMI

High Pressure Mercury Injection

HPMI -  (also termed Mercury Injection Capillary Pressure – MICP) Capillary pressure plays an important role in understanding fluid distribution in a reservoir. This has a crucial
impact on understanding heterogeneity and eventually the performance of the reservoir. It has many applications in formation evaluation including but not limited to:

  • Drainage capillary pressure and saturation height modelling​

​​

  • Pore throat size distribution – micro porosity control on water saturation


  • Rock typing


  • Sample selection for SCAL


  • Integration with NMR from log and core


  • Selection of pressure points for capillary pressure by centrifuge, porous plate and de-saturation to Swi (for reservoir engineering SCAL) 

  • Entry pressure and threshold pressure (seal capacity)


CTS are able to offer this service in-house at our facility in Aberdeen where we have two Micromeritics Autopore IV systems – automated 0 – 60K psi.

MICP analysis is a very powerful rock quality and pore fabric description tool and provides strong qualitative indicators concerning likely relative permeability behaviours.

AutoPore IV Advantages

  • Ability to measure pore diameters from 0.003 to 360 μm​

  • High-pressure generating system can achieve 60,000 psi

  • Enhanced data reduction package; includes tortuosity, permeability, compressibility, pore-throat ratio, fractal dimension, Mayer-Stowe particle size, and more

  • Equilibration by sample-controlled, rate of intrusion

  • Operates in scanning and time- or rate-equilibrated 

  • Collects extremely high-resolution data; better than 0.1 μL for mercury intrusion and extrusion volume

  • Controlled evacuation prevents powder fluidization
