Abstract:
The goal of this study was to create a tool with the use of an artificial neural network (ANN) that could quickly predict the inverse solution to pressure transient (PT) data created for multiple multi-lateral wells completed within a tight-gas dual-porosity reservoir. This inverse tool would be able to predict the user’s reservoir parameters nearly instantaneously with known inputs of PT data and wellbore design. This tool will take ideas from current well test analysis to aid in the training of the neural network. However, once the network has been trained, it will be able to predict multiple key reservoir properties and the time consuming process of conventional well test analysis will no longer be an issue.
