Abstract
- The Cardium Formation “halo oil” occurs either in the fringe of, or between, existing conventional discrete sandstone reservoirs. It is commonly associated with conventional oil and gas pools in stratigraphic traps. This paper uses a geological model-based simulation approach to assess Cardium “halo oil” resource potential. The geological model-based approach consists of a geological model, a resource model and a stochastic modeling procedure that extracts essential information regarding the richness and spatial characteristics of oil resources from various data sources using statistical methods. It integrates them with the geological and resource models, respectively, to estimate the resource potential. This approach predicts not only the resource potential, but also the resource spatial distribution and the exploration risk. These outcomes provide critical information for exploration decision-making. Cardium “halo-oil” assessment results indicate a mean total oil in-place (conventional and unconventional) of 4.6×109 m3 and a mean undiscovered “halo oil” in-place of 2.9×109 m3. Using current technology and economic constraints the undiscovered recoverable “halo oil” in this tight formation is 0.11×109 m3. This represents
