Characterizing Previous HitUnconventionalNext Hit Resource Potential in Colombia; A Digital Rock Physics Project

Joel Walls

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:

  • 31,058 ft, 139 wells
  • Phase 2 & 3: Previous HitUnconventionalNext Hit Rock Quality Workflow MicroCT & 2D SEM analysis was performed on 65 wells (4357 plugs, 87000+ 2D SEM images analyzed) Top 3 basins analyzed:

  • Catatumbo (1709 plugs)
  • Llanos (842 plugs)
  • Middle Magdalena Valley (803 plugs)

  • 3D FIB-SEM analysis was performed on 453 samples. Top 3 basins analyzed
  • Catatumbo Basin (141 poro-perm samples)
  • Middle Magdalena Valley (220 poro-perm analyses)
  • Llanos Basin (56 poro-perm samples)
  • In addition, the core data was Previous HitintegratedNext Hit with well log data for about 134 wells in order to develop and refine a petrophysical model for Previous HitunconventionalNext Hit Previous HitresourcesNext Hit. This presentation will show some of the results and discuss the implications for shale resource potential from these basins.
