New Petrophysical Workflow Helps Improving Fluid Forecasts and Production Rates in the Estancia Cholita Field, Argentina

摘要

The project focuses on the optimization of the completion stage of wells of the Estancia Cholita Field, San Jorge Basin,Argentina. Its principal objective was to develop a workflow to improve identification of oil reservoirs and increase the current primary recovery factor of the field. During the study, a reservoir characterization methodology was developed to select the intervals of major potential of the well and to identify the water zones. The methodology leads to a calculation of a variable RW profile for every well. The petrophysical model was designed to use the RW profiles to guide the evaluation.
