Background
WellDog, founded in 1999, provides a service that analyzes coalbed natural gas reservoirs in order to help its customers produce more gas, more quickly, with less cost and less water production. The company has provided commercial services since mid-2004 and currently provides coalseam reservoir analysis services in North America including, the Mannville coals on central Alberta. Problems in coalbed production include rising infrastructure costs, increasing regulatory requirements, and lack of scientific data to assist exploration and production. All of these issues reduce the return on investment for the producer. WellDog's technology helps the producer address these important issues.

WellDog provides its clients with a "window" into the coalbed reservoir. The process for doing this begins with the insertion of our patent-protected chemical assay tool into the wells, which are typically 10.16 to 17.78 centimeters in diameter and thousands of meters deep. The assay tool, while in the well, gathers data on the chemical composition of the formation which is relayed to the surface then, via satellite, to WellDog's Data Analysis and Interpretation Center (DAIC) at its headquarters in Laramie, Wyoming. At DAIC, the data is rigorously quality checked to provide the well's producer with reliable information on the production potential of the well 3-5 days after the well is tested. No other technology provides information as accurately and rapidly.

Presentation Description
Gas desorption methods to analyze coal gas content require expensive core retrieval methods and extended desorption and analysis time. These methods have inherent problems and errors associated with the retrieval process and testing in a laboratory environment.

WellDog has adapted its new downhole Raman spectrometer to measure gas content in coalbed wells without core sample retrieval, in a matter of hours. This technology, which has been successfully calibrated in three independent laboratories using state-of-the-art Boyle's Law isotherm apparatus, accurately measures gas content in wells containing one or more coals seams, in situ.

This presentation will show the methods behind the analysis and share laboratory calibration and field case study results. It will also review how same-day analysis of gas content is leading to new, more efficient coalbed natural gas development methods for our customers.
