Three-Dimensional Modelling of Desorbed Gas Volume and Comparison to Gas Production Rate in the Montney Plays, Western Canadian Sedimentary Basin

Table 4

Five wells compared between the log-based estimated desorbed gas volume and gas production history data. From cum 12-44 to cum 35-44 refers to the sum of gas production month. Length refers to the horizontal length used for gas production of well. This length was divided into stages as a given standard, and its average length represents the average stage spacing. AB: Alberta; BC: British Columbia; E3m3: thousand cubic meter.
