GIS Applications and Programs Predominantly use ArcView 3.2 Spatial Analyst based procedures Limited use of ArcGIS/ArcMap – technical issues Limited use of ArcINFO
Coal Mining – CBM “Conflicts” Coal mine dewatering causes extensive water drawdown which reduces hydrostatic pressure in the coal and allows methane to desorb. Escape of methane depletes CBM resource. 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. Assessment of CBM resource is necessary to support CBM development, coal leasing and mine development.
Geologic/Reservoir Analysis Raw data include CBM well data, coal drill hole data, groundwater/hydrostatic data and coal analyses Procedures include gridding/surface generation, contouring and map-based calculations (“map algebra”)

Gas Content Calculations: 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)
Initial and depleted gas content can be mapped.

CBM Resource Assessment Goals Economic evaluation of CBM drilling and production for consideration in mine planning. Evaluation of effects on CBM resources by coal leasing or mining. 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.
Coalbed Methane Drainage If development does not occur uniformly, drainage or depletion of CBM reservoirs can result. 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.

Drainage review and evaluation: Requires evaluation of production from individual wells, regional depletion, reservoir communication across lease lines, flow boundaries, etc. Can be done on an individual well – lease basis. We are developing reservoir modeling/simulation programs to evaluate drainage from multiple wells or regional water drawdown. GIS applications can be used to develop modeling data.
Reservoir Modeling Applications Gridding data themes can produce input data layers for reservoir simulation. ArcINFO “GRIDASCII” procedure used to export grids. ASCII grid files support a variety of applications.

GIS Applications and Programs Predominantly use ArcView 3.2 Spatial Analyst based procedures Limited use of ArcGIS/ArcMap – technical issues Limited use of ArcINFO
Coal Mining – CBM “Conflicts” Coal mine dewatering causes extensive water drawdown which reduces hydrostatic pressure in the coal and allows methane to desorb. Escape of methane depletes CBM resource. 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. Assessment of CBM resource is necessary to support CBM development, coal leasing and mine development.
Geologic/Reservoir Analysis Raw data include CBM well data, coal drill hole data, groundwater/hydrostatic data and coal analyses Procedures include gridding/surface generation, contouring and map-based calculations (“map algebra”)

Gas Content Calculations: 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)
Initial and depleted gas content can be mapped.

CBM Resource Assessment Goals Economic evaluation of CBM drilling and production for consideration in mine planning. Evaluation of effects on CBM resources by coal leasing or mining. 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.
Coalbed Methane Drainage If development does not occur uniformly, drainage or depletion of CBM reservoirs can result. 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.

Drainage review and evaluation: Requires evaluation of production from individual wells, regional depletion, reservoir communication across lease lines, flow boundaries, etc. Can be done on an individual well – lease basis. We are developing reservoir modeling/simulation programs to evaluate drainage from multiple wells or regional water drawdown. GIS applications can be used to develop modeling data.
Reservoir Modeling Applications Gridding data themes can produce input data layers for reservoir simulation. ArcINFO “GRIDASCII” procedure used to export grids. ASCII grid files support a variety of applications.
