Characterizing Unconventional Resource Potential in Colombia; A Digital Rock Physics Project
Joel Walls
InGrain
This four month project involved detailed analysis of slabbed core from 6 basins in Colombia. The majority of the core came from the Llanos, Middle Magdalena, and Catatumbo basins. The overall analytical program consisted of;
Phase 1: Whole Core X-ray CT Imaging, Total Core Scanned:
Phase 2 & 3: Unconventional Rock Quality Workflow MicroCT & 2D SEM analysis was performed on 65 wells (4357 plugs, 87000+ 2D SEM images analyzed) Top 3 basins analyzed:
3D FIB-SEM analysis was performed on 453 samples. Top 3 basins analyzed
In addition, the core data was integrated with well log data for about 134 wells in order to develop and refine a petrophysical model for unconventional resources. This presentation will show some of the results and discuss the implications for shale resource potential from these basins.
