Development of Insight in Complex Pore Space of Carbonate Reservoirs by 3D Visualization of Computed Tomography Scans

Anuj Gupta, Frank Platt, Hussein Jichi and Mohammed Al-Kubaissi (Texas A&M University at Qatar) 

The objective of this project is to provide students with a better understanding of the complex pore-structure of carbonate reservoirs.   In addition, a longer-term objective is to develop conceptual, mathematical and simulation models to capture the complex pore-structure of carbonate reservoirs and to develop teaching material that gives students insight into such complex systems. Such models are needed to develop optimum methods for drilling, completion, stimulation of wells in carbonate reservoirs, as well as to maximize oil & gas recovery from such reservoirs in a cost-effective manner. 

3D visualization of CT-scans provides valuable insight into the complex pore-space architecture of carbonate reservoirs. In ongoing CO2 sequestration project, change in pore-space during interaction of reservoir with CO2 is being investigated. In acid-jetting project, acid is injected to create flow-pathways in tight carbonate reservoirs. In both projects, 3D visualization of CT-scans before and following interactions will allow thorough understanding of the change in pore-space due to interaction with CO2/acid.
