Optimization of Hydraulic Fracturing Parameters to Increase Gas Well Productivity

Abstract:

The article examines the development features of the studied gas field and analyzes the efficiency of different hydraulic fracturing (HF) technologies. An integrated analysis of the field’s production history was carried out, covering the evaluation of applied HF methods, results of diagnostic injection tests, regression calculations, and characterization of fracture parameters. Historical production and reservoir pressure data were used to calibrate a material balance model in MBAL, ensuring consistency between observed and simulated results. HF operations using both crosslinked gel and slickwater were analyzed. Results of DFIT and mini-frac tests allowed the determination of key fracture parameters – length, height, conductivity (FCD), net pressure, and fluid efficiency. Based on the integrated dataset, a five-year forecast of field performance was developed. Wells treated with slickwater demonstrated higher and more stable flow rates compared with conventional crosslinked gel treatments, especially under lower reservoir pressures and timely well clean-up. The study emphasizes the importance of combining historical production analysis, fracture diagnostics, and regression methods with material balance modeling for reliable long-term productivity forecasting. The findings provide practical implications for optimizing HF parameters, selecting fluid systems, and planning reservoir development strategies aimed at maximizing gas recovery under depletion conditions.
