| Abstract | Detailed analysis of the pressure and temperature profiles measured in individual Baca wells determine those locations at which the measurements correspond to the actual conditions in the fractured formation. The reservoir pressures identified from the well by well analysis indicate a uniform initial pressure gradient across the reservoir corresponding to a hydrostatic gradient at approximately 500°F. The initial temperature contours constructed from the well analysis dome upward and an initial two phase region lies at the crest of the dome. Two permeable zones are identified. The shallower, more permeable, zone lies within the Bandelier Tuff; the deeper zone corresponds to the interface between the Bandelier Tuff and the underlying Andesite. With fluid production, the two phase zone will expand, but the reservoir will always contain liquid and two phase regions. |
