The targeted formation, in this 10 injection well array, was obviously the Dakota Sandstone and Graneros interval.
Seismic activity centered on Trinidad dam, above Trinidad, illustrates the potential seismic dangers of fracking and injection wells, the latter in particular when near dams.
The lake and dam's weight may have pre-stress the strata.
Such logging into the Morrison Formation, and fracking (or injecting) into the Dakota Sandstone will contaminate the Rios Gallina and Chama Watersheds, being particularly hazardous for those communities downstream.
