Rock Mechanics and Rock Physics

The properties of porous rocks arise from relations between microscopic effects due to the granular constituents and macroscopic effects governing the bulk of the rock. Merging of information between the microscopic and the macroscopic in order to model the macroscopic measurable properties is the challenge faced. Special emphasis is placed on incorporating geological information, affixing the rock physical models to the formation history of the rock. The investigation methods employed are laboratory measurements, wireline logging and geological considerations.


Smart Water - Advanced Waterflooding of Danish Oil and Gas Reservoirs

Smart water is an advanced waterflooding method. Advanced waterflooding is a collection of new promising methods of improved/enhanced oil recovery. Unlike other EOR methods, like surfactant or polymer-micellar flooding, the novel methods may improve the recovery without high additional expenses, and help to avoid accompanying logistical and environmental problems. The “smart water” injection strategy is based on laboratory experimental observations that variation of the injected water salinity and of its ion balance may result in large additional recovery. The objectives of this research are:

  • To find the mechanisms behind the action of smart water.
  • To investigate the effect of differences in rock type, e.g. chalk, sandstone.
  • To investigate the effect or reservoir fluid.
  • To find a cheap source of smart water.

Heat Storage in Hot Aquifers: the Effect of Temperature on the Rock Physical Properties of Sandstone

Research is being conducted to assess potential effects of heating the rock and to evaluate which formations are most suitable for heat storage. Geomechanical tests are performed to determine whether the strength and stiffness of the rock are affected by heat storage. Geochemical tests are performed in collaboration with GEUS to investigate interactions between the fluid and the rock at temperatures and pressures similar to those in the aquifer.
