The success of well stimulation methods, particularly those intended to treat large volumes of reservoir, is enhanced by data visualization and analysis. This is easily accomplished with the tools provided in the CoViz 4D
software package. Candidate selection, treatment design, production forecasting, and economic analyses are keys to success. While wellbore problems can be treated with simple chemical stimulations requiring little data besides the nature of the obstructions themselves, the design of large stimulations can require volumes of both geologic and engineering data and this is due to heterogeneity inherent in reservoir characteristics.
