gas potential of the uintah basin E extensive exploration fo oil and gas has been announced during the coming year the first well which was drilled fr gas or oil was the john P V vell veil drilled with r C la Is in this well a seated on the south flank the uintah dasin basin south of mccork ridge by poor peor spring this early wildcat well was no geologically well located for it was studded about feet above a well saturated tar sand in the wasatch formation the tar sand was waa exposed on tile the cliffs to tile south of the well this early pion pioneer eee operator evidently hoped to f
