Claim 0:
1. A method for modeling water distribution in a reservoir having a gas phase, a free water phase, and a plurality of pores, the method comprising:
determining a free water level in the reservoir;
analyzing a free water pressure trend of the free water phase;
determining a presence of anomalous pressures and salinities within the free water phase;
determining whether gas down to models and water up to models fit the reservoir;
determining a bi-modal pore throat distribution of the plurality of pores within the reservoir;
generating a difference map to model the water distribution in the reservoir;
determining a top pay zone of the reservoir using the difference map, wherein the top pay zone is a portion of the reservoir where the gas phase is located; and
drilling a well into the top pay zone of the reservoir to produce gas using the well.
