• Development of Engineering Guidelines for Shale Gas Wells Influenced by Longwall Mining
  9/18/2020 - Research projects
  A project to address the lack of information on longwall-induced subsurface strata deformations and stresses and their effect on shale gas well casings by conducting detailed analysis and instrumentation on unconventional shale gas wells.
• Stability Evaluation of Active Gas Wells in Longwall Abutment Pillars
  9/16/2020 - Research projects
  A project to evaluate and quantify subsurface overburden deformations in longwall abutment pillars under shallow overburden depths, and to employ field instrumentation results and 3D numerical modeling to identify critical parameters.
• Transport Model for Shale Gas Well Leakage Through the Surrounding Fractured Zones of a Longwall Mine
  9/1/2020 - Peer reviewed journal articles
  An article presenting an analytical model of gas transport through fractures in a low permeable stratum.
• Foam Stimulation To Enhance Production From Degasification Wells in the Pittsburgh Coalbed
  1/1/1978 - Reports of Investigations
  Seven degasification wells have been completed in the Pittsburgh coalbed at the New Emerald Mine near Waynesburg, Pennsylvania. The Bureau of Mines performed stimulation treatments on five of the wells.
• Improved Methods for Monitoring Production From Vertical Degasification Wells
  1/1/1978 - Reports of Investigations
  In this Bureau of Mines investigation, production was monitored for 1 year at over 30 coalbed gas-drainage boreholes located in Alabama, Pennsylvania, and West Virginia.
• Demonstration of Safety Plugging of Oil Wells Penetrating Appalachian Coal Mines
  7/1/1972 - Technical Progress Reports
  An oil well penetrating the Pittsburgh bituminous coalbed in northern West Virginia was plugged and safely mined through 3 months later. Effectiveness of the plugging in preventing reservoir gas from entering the mine through the well hole was verified ...
• Methane Emission in Coal Mines: Effects of Oil and Gas Wells
  1/1/1972 - Reports of Investigations
  The method of moving averages was found useful in assessing the nature of methane emission in coal mines. Emission rates were influenced markedly by the presence of abandoned oil and gas wells in the vicinity of the mine. Such wells appeared to increase...
