• Reconciling Longwall Gob Gas Reservoirs and Venthole Production Performances Using Multiple Rate Drawdown Well Test Analysis
  12/1/2009 - Peer reviewed journal articles
  In this paper, the production rate-pressure behaviors of six gob gas ventholes drilled over three adjacent panels were analyzed by using conventional multi-rate drawdown analysis techniques.
• The Limiting Oxygen Concentration and Flammability Limits of Gases and Gas Mixtures
  6/1/2009 - Peer reviewed journal articles
  This paper presents data on the limiting (minimum) oxygen concentration in the presence of added N₂, methane, propane, ethylene, carbon monoxide, and hydrogen and some of their binary mixtures, and addresses flammable concentration limits.
