Abstract: Alberta Geological Survey created a coal and coalbed methane (CBM) database to capture and manage CBM data. The database compiles different sources and contains information on 7923 wells (15,200 formation picks, 37,357 coal picks, 495 coal analyses and 363 vitrinite reflectance measurements). From this parent dataset, individual coal zone was evaluated. This record describes the Lethbridge coal zone's calculated gas content.

Data quality: Scope: Scope: Hierarchy level: Scope code: dataset Report: Completeness commission: Result: unknown Report: Completeness omission: Evaluation method description: Contours are generated from gridded surface without applying any smoothing function.

Result: unknown Lineage: Lineage: Statement: Contours are generated from gridded surface without applying any smoothing function. They are continuous and clipped with the coal zone boundary Process step: Process step: Description: The calculated depth to top values were extracted from Viewlog and used to calculate the gas content using the following formula: Gas content dry, ash-free basis (daf) was calculated for the coal zone using the equations: 1) For depth to top > 200 m: gas concentration (cc/g, daf)=Lv x (depth x grad)/(depth x grad)+(Lp x 0.70) and 2) For depth to top < 200 m: gas concentration (cc/g, daf)=Lv x (depth x grad)/(depth x grad)+(Lp x 0.40) where Lv is Langmuir volume (cc/g, daf) and Lp is Langmuir pressure (Mpa), both obtained from isotherm analyses; depth is depth to top of coal zone (m); grad is pressure gradient (Mpa); daf is dry, ash free basis; and 0.70 and 0.40 are gas saturation values. Saturation per cent determined by comparing gas adsorption capacity (Langmuir parameters) to measured desorbed gas content. Note: Langmuir volume and pressure were determined by laboratory analysis on Alberta coal samples from each coal zone in question according to Langmuir, I.:, The Adsorption of Gases on Plane Surfaces of Glass, Mica, and Platinum, Journal of the American Chemical Society, Vol. 40 (1918) pp. 1,361-1,403. From the above calculations, a gas content estimate (cc of gas per g of coal) on a dry, ash-free basis for the Lethbridge coal zone was generated. Results were gridded and contoured in Viewlog using its Simple Kriging method. Contour lines were exported from Viewlog as a DXF file. This was then imported into ArcGIS and exported as a shapefile.
