Description
This submission contains several shapefiles used for a deterministic PFA, as well as a heat composite risk segment with union overlay, and training sites used for weights of evidence. More detailed metadata can be found in the specific file.

|---|---|---|---|
| Deterministic PFA Dissolve.zip | ZIP | This is the final deterministic geothermal play fairway analysis model of the Tularosa Basin, New Mexico and Texas. This layer was created by applying Dissolve to the Union overlay version to simplify polygons. Petroleum industry logic was used for this model (Reference: Fraser, et al., 2001). | Open resource |
| Deterministic PFA Model.zip | ZIP | This is a deterministic geothermal play fairway analysis model of the Tularosa Basin, New Mexico and Texas. It was created using petroleum industry logic (see paper referenced below). Composite risk segment (CRS) maps representing heat, fracture permeability, and ground water were fused using the Union Overlay method. Polygons were then classified as low, medium, or high risk based upon input CRS values (Fraser et al., 2001). | Open resource |
| Heat Composite Risk Segment.zip | ZIP | This is the heat composite risk segment of the Tularosa Basin, New Mexico and Texas -- used for geothermal play fairway analysis. Temperature gradient, quartz geothermometer, and heat flow data were integrated using the Union overlay method. Classification was as follows. Temperature Gradients: 0 degC/km – 60 degC/km = High Risk; 60 degC/km – 80 degC/km = Medium Risk; > 80 degC/km = Low Risk. Quartz Geothermometers: 0 degC – 60 degC = High Risk; 60 degC – 80 degC = Medium Risk; > 80 degC = Low Risk. Heat Flow: 55 – 70 = High Risk; 70 – 85 = Medium Risk; > 85 = Low Risk. | Open resource |
| Deterministic Certainty.zip | ZIP | This is the final deterministic certainty layer for Tularosa Basin deterministic play fairway analysis. Certainty was based upon the presence, spatial correlation, and agreement of heat composite risk segments. | Open resource |
| Weights of Evidence Training Sites.zip | ZIP | Tularosa Basin weights of evidence play fairway analysis training site points from known geothermal systems and hot springs. The training sites in this dataset were taken from hot springs and know geothermal areas in the Great Basin and New Mexico. These were used in weights of evidence PFA analysis. | Open resource |
