Evaluation requires estimation of initial (i.e. pre-mining) and current (i.e. depleted) pressures and gas content.
Simplified procedures are normally used due to data constraints.
Coal mine dewatering causes extensive water drawdown which reduces hydrostatic pressure in the coal and allows methane to desorb.
Coal Mining – CBM “Conflicts”Coal Mining – CBM “Conflicts”
Escape of methane depletes CBM resource.
Assessment of CBM resource is necessary to support CBM development, coal leasing and mine development.

Gas Content EstimationGas Content Estimation
The predictive equation from the adsorption isotherms can be used to estimate gas content (storage capacity) based on hydrostatic pressure.
In this example:-0.00005x2 + 0.1327x + 2.4611 = methane storage capacity
where,x = Hydrostatic Pressure (from pressure surface maps)

Economic valuation and projections for CBM resources and wells in potentially mined parcels.
Drilling and production economics to support timely CBM drilling in mine areas.
Economic evaluation of CBM drilling and production for consideration in mine planning.
CBM Resource Assessment GoalsCBM Resource Assessment Goals
Evaluation of effects on CBM resources by coal leasing or mining.
If development does not occur uniformly, drainage or depletion of CBM reservoirs can result.
Coalbed Methane DrainageCoalbed Methane Drainage
This is caused by reductions in hydrostatic pressure that result from “regional” groundwater drawdown as coal seams are de-watered.
Pressure depletion always affects the CBM reservoir.
In cases of diverse mineral ownership this can also affect production and revenues.
