Coalbed methane systems:
Despite growing commercial interest in coalbed methane resources, surprisingly little is known about the hydrologic systems which have maintained gas in the coals, and their long-term response to human activity. Growing concerns about the effect of removal of co-produced brines on local water quality have made the need for knowing even short-term consequences imperative. We use a variety of naturally occurring environmental tracers to determine the source an migration of brines, including 129I, 36Cl, 2H, and 18O. Research was carried out on the Fruitland Formation coals of the San Juan Basin in New Mexico and Colorado. In central portions of the basin, iodine ages correlated with the 73 Ma depositional age of the coals, showing minimal migration of entrapped fluids. Infiltration on the uplifted edges of the basin were indicated by high concentrations of anthropogenic 129I.
