For carbonate reservoirs

From 50 to 60 percent of hydrocarbon reserves in the world are stored in carbonate rocks. Carbonate reservoirs are characterized by poor continuity of rocks in terms of thickness and quality. That makes it harder to compare them with each other.

The main feature of reservoir rocks of this type is diagenetic porosity which affects reservoir characteristics of carbonate rocks. Secondary porosity is most commonly presented with recrystallization, metasomatism and fissuring. This leads to the need to determine origin of each fracture inside the core: is it artificial or real.

IntroVision technologies allows elimination of artificial fractures from the core samples analyzed.

    In addition to conventional laboratory research for carbonate rocks IntroVision offers direct determination of:

  • Layering direction
  • Full porosity
  • Open, closed and effective porosity
  • Fracture opening
  • Directional permeability

within CT scanner resolution.

Values indicated can be characterized numerically and visualized as 3-dimentional objects.
