Abstract
A numerical model was developed to study the production behavoir in the Mobara type water-dissolved natural gas reservoir which was composed of horizontal beds of alternating mudstones and sandstones. The model consists of the mathematical description of a horizontal, two phase (water and methane gas) flow in the two-dimensional sandstone layer, assuming the vertical, one dimensional diffusion of the desorbed gas from the mudstone.The methane adsorbtion volume for the mudstone was calculated assuming the Langmuir's adsorbtion isotherm. The model was applied to simulate the behavior of the reservoir of the Mobara type gas field.From the results of simulation, it was concluded that the model was valid for the Mobara type gas reservoir and that the effects of desorbed gas from the mudstone on the GWR behavior could be simulated by the proposed model.
