C&P: "Optimizing Hydraulic Fracture Performance in the Eagle Ford Oil Window - More Proppant is Better"
This presentation will provide a case study on how one operator with acreage in the Frio County oil window of the Eagle Ford was able to significantly improve production results by testing different drilling targets, completion types (sliding sleeves and plug-and-perf), and fracture treatment designs. Early results were mixed, with initial plug-and-perf completions underperforming earlier sliding sleeve wells. It was determined through data analysis and production normalization techniques that the plug-and-perf treatments were under-stimulated with inadequate proppant being placed in individual fractures.
Once proppant amount per cluster was identified as a high-impact parameter, subsequent stimulations were performed with larger proppant volumes. These later wells experienced significant improvements in production performance, with each step-wise increase in stimulation design consistently resulting in better production performance. Scatter plots, cumulative production charts, and fracture modeling runs comparing different design scenarios will be presented to show how these factors were discovered.
