CO2, H2 and Hydrocarbon Multiphase and Reactive Transport Flow Laboratory

Experimental equipment I designed and built at Edinburgh University can recreate in-situ reservoir conditions with multi-phase flow through rock to provide complete parameterisation of the coupled thermo - hydro - mechanical and chemical mechanisms for the fluid / rock mineral system.

The equipment consists of a Hassler-type high pressure cell which holds cylindrical rock samples of 38mm diameter and up to 75mm in length. The pump is designed for high temperature, pressure and supercritical CO2 and all wetting parts are in 316 stainless steel or PEEK to limit corrosion.

The system can provide in-situ and scalable measurements at range of pressures, temperatures, rock types and fluid types to provide insight into characterising the thermo - hydro - mechanical and chemical processes associated with the flow of supercritical and dissolved CO2 through the reservoir, aquifer and cap rocks.

The experimental equipment is rated to provide:

  • Up to10000psi (689 MPa) pressure.
  • Up to 90oC fluid and rock temperature.
  • Supercritical CO2 and brine fluid flow (both single and multi-phase).
  • Sample upstream and downstream pressure along with the differential pressure.
  • Scope to add tracers (or other markers).
  • Take up and downstream fluid samples for detailed chemical analysis using a suite of analysis techniques including; continuous flow analysis, coulometry, atomic absorption spectrophotometry and C/H/N analysis. 
  • Obtain rock samples pre and post in-situ CO2 flow for detailed petrophysical analysis using a suite of analysis techniques including; SEM, XRD, X-Ray C, XRF and the ion microscope.

The experimental apparatus is housed in a protective rig within a laboratory with extraction facilities and CO2 monitoring equipment.
