The Humble Gas Library (HGL) is a collection of analytical results from wells around the world. There are approximately 241 international gas analyses and over 13,000 from the United States.
The data available includes hydrocarbon (C1-C6+) and nonhydrocarbon (carbon dioxide, hydrogen sulfide, nitrogen, oxygen, helium, hydrogen, and argon) gas composition as well as calorific values. An additional 9000 wells are included in the Excel and Access versions from the USGS gas assessment.
These data are useful for mapping areas in a region, basin, or field to evaluate the zones with the highest calorific values. Calorific value (measured as BTUs or British Thermal Units) is easily related to gas composition. As the gas wetness increases the calorific value increases as shown in Figure 1. These are data from the Ft. Worth Basin, Texas, which is a shale gas play.

These gas data can be used in conjunction with classical geochemical data such as TOC, Rock-Eval, vitrinite reflectance, and thermal extract gas chromatographic (TEGC) fingerprints to high-grade the highest quality reservoirs in a field and to assess products at various maturation levels for a given petroleum system.
Pricing of the gas library is $10.00 per sample in Excel or Access formats. Didger based maps available by region for additional charge.
