This paper presents an uncertainty analysis of coalbed methane resources estimation for a coal seam gas field containing multiple coal seams. Firstly, logs from nine wells and laboratory data from nine coal seams were used to predict the coal thickness, ash content and gas content at nine boreholes. Secondly, the structural models were determined using the well correlation, structural contour and...
Well Stimulation and machinery extraction are two main methods which oil production engineer and related industries use to increase production. The purpose is to enhance the oil field final recovery ratio by speeding up the production rate of the petroleum fluids, especially for an old oil field development. We formulate a set of methods which is suitable for predicting output of well simulation in...
