Analysis of the results of modeling fluid inflow to a hydraulic fracturing

Abstract

Relevance. The fact that, hydraulic fracturing is the efficient method for intensifying the inflow in "mature" fields. But, despite on its efficiency, it can cause unpredictable increase of water cut in a well. In this regard, the problem of predicting the behavior of the water cut in wells after hydraulic fracturing is topical. Aim. To create the model to predict the increase of water cut in well using the Buckley–Leverett function with known hydraulic fracturing parameters during the year after hydraulic fracturing. Object. Model of well water cut growth after hydraulic fracturing. Methods. Simulation of water cut in wells after hydraulic fracturing using the Python programming language, followed by an assessment of the convergence of the simulated data with actual data obtained from the Vankor oil and gas field. Results. It was shown that during the year the water cut gradually increased from 10 to 31%. The convergence of the simulated and real data was 98%. Conclusion. A model has been created to predict the increase in water cut in a well after the hydraulic fracturing. The high convergence of the simulated and actual data indicates the correctness of the application of the Buckley–Leverett function to predict the increase in water cut in the well after the hydraulic fracturing.
