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.
