Focus your drainage operations on your gas and accelerate mining operations while minimizing greenhouse gas emissions. WellDog’s GasMapper service uses our patented, award-winning Reservoir Raman systems to quickly map gas distributions both laterally in coal seams and vertically between coal seams, allowing you to plan cost-effective, accelerated drainage operations.

• Fluid analysis allows you to avoid the petrophysical heterogeneity that interferes with gas and water reservoir evaluations using core samples.
• In situ analysis allows WellDog to analyze literally hundreds to thousands of fluid samples for each coal, insuring that the results accurately represent your future drainage needs.
• Our gas-specific instruments allow us to simultaneously analyze your formations for methane, carbon dioxide, nitrogen and higher hydrocarbons.
• By combining our gas measurements with adsorption isotherm data synthesized from multiple cores or from a core and multiple density measurements, you can calculate the most accurate, representative gas-in-place available for use in greenhouse gas emissions accounting.
• Our patented equipment enables you to confidently analyze fluids downhole in new wells or at the wellhead from producing drainage wells.
• Our e-line, real time systems allow us to maximize job efficiency and deliver data to you in hours, not weeks or months

And our unique operational flexibility allows you to map your gas in a myriad of situations:

• New drills with casing
• Existing single zone completions
• Single zone wells under drainage
• Re-entries into stringers behind existing casing
• Multizones behind casing, using perf/plug strategies

And check out our GasMapper Plus for even more operational flexibility.

Combine the GasMapper with our DrainageMonitor systems for a full spectrum drainage validation service.
