DIAGENESIS RESEARCH AT EDINBURGH UNIVERSITY

POROSITY CHANGE IN HYDROCARBON RESERVOIR SANDSTONES

Thank you for your interest in our research at Edinburgh, in the School of GeoSciences. We believe this to be the only group in the UK specifically studying porosity change and palaeo-fluids in sedimentary basins. The group is led by Stuart Haszeldine

Aims:

Our aims are to reconstruct the porosity and permeability changes in hydrocarbon reservoir sandstones during burial. This requires examination of the pore-fluid history of sedimentary basins, as an aid to understanding where the ions came from, where the ions went to, and how the pore-water moved or did not move.

Approach:

Our approach is to utilise and combine information from any disciplines appropriate to help solve the problem.
The main techniques we use are listed below.

• Structure and sedimentology
• Petrology
• Stable and radiogenic isotopes
• Fluid inclusions
• Basin modelling
• Petrophysics
• Seismic reflection imaging
