The rock quality of nine major hydrocarbon basins of Colombia was analyzed using a new technology called digital rock physics (DRP). The study consisted of image and computational analysis on 140 wells from the national core repository "Bernardo Taborda" provided by the Agencia Nacional de Hidrocarburos (ANH). Targeting shale rich reservoirs, the three main basins of study were the Catatumbo, Llanos, and Middle Magdalena Valley. A DRP analysis that scaled resolution with sample size was performed until individual pores were visible and computations of porosity and directional permeability could be calculated. Numerically efficient fluid flow algorithms allowed for the computation of shale reservoir properties and provided clear 3D renderings of pore and organic matter structures. Once core analysis was complete, DRP data was integrated with well log data in order to create an upscaled petrophysical model for 134 wells found in these basins.
Within these three basins the La Luna and Gacheta formation data are presented here. Multiple digital imaging techniques and computations were used to determine properties such as mineralogy, porosity, organic content, porosity associated with organic content and absolute permeability. Upon completion, a comparison was made with the Eagle Ford and Wolfcamp formations from North America. The data show the rock qualities from the Colombian samples are comparable.
