Abstract:
Results of a case study of a well in the Llanos Basin in Colombia are presented to demonstrate how the gas-chromatographic (GC) fingerprints of oils from the well were evaluated using InfoLogic's ReserView™ and OilUnmixer™ programs to successfully delineate the producing reservoir intervals, identify vertical reservoir fluid compartments, as well as estimate and monitor the production allocation of a 2-zone completion over a seven-month period. The reliable results from the unbiased comparison of the oils using the programs identified the reason for a reduction in production, why the API gravity of the commingled oil decreased, and why the Gas-Oil Ratio (GOR) increased over the seven-month period. The geochemical approach cost approximately 95% percent less than if three production logging tool (PLT) events had been employed.
