In addition, if the barrier islands disappear, the region's wetland-oriented oil and gas wells and associated infrastructure will be at risk to open Gulf conditions.
      
On the possibility of acoustic probing of gas wells
      
The possibility of probing the critical areas of gas wells using acoustic signals is analyzed.

Soil pCO2 and DOC samples were collected from soil gas wells and tension lysimeters, respectively, at depths of 15, 30, and 125?cm.
      
Acid Mine Drainage Flowing from Abandoned Gas Wells
      
In northwestern Pennsylvania (USA), numerous abandoned natural gas wells are producing artesian flows of Fe-contaminated water.
      
We propose that AMD formed in the coal mines is infiltrating into lower aquifers, moving outside the lateral limits of mining, and using abandoned gas wells as conduits to the surface.
      
This would suggest that current remediation strategies that emphasize plugging the pollution-producing gas wells may be ill-advised because the source of the polluted water is more shallow than currently assumed.
      
Successive groupings of oil and gas wells were used to determine an environmental index which was used to establish the hydrocarbon producing potential of the next group.
      
With this dichotomy, production estimating functions which explain 74% of the variation for oil wells and 78% of the variation for gas wells were formulated.
      
It is established that the relationship between methane emission from surface gob gas wells and the duration of well production can be described by Gaussian (normal) distribution.
