A lookback study of well performance using borehole image data

Abstract

The main objective of this work is to understand the impact of fracture, stress, drilling direction, and other reservoir properties on the production performance of a horizontal well (HW) in the Karachaganak Field. Taking advantage of the 70 available borehole image logs helped extend the analysis beyond individual wells to a field scale evaluation. Three analysis methods were developed to progress with the study: a favored drilling direction map, a Reservoir Property Filter, and crossplotting for multiple reservoir properties to gauge well performance. Results showed linear, nonlinear, and multidimensional relationships. The findings will be used to guide future HW drilling optimization, support dynamic modeling, and improve the model’s predictability for effective reservoir management.
