Mr. Greenhalgh is a Geologist at Hansen, Allen & Luce, Inc. (HAL). Scott has worked closely with drilling and completion engineers to plan successful wells that minimize drilling risk and environmental impact, constructed 3D static, geocellular representations of subsurface reservoirs, created uncertainty management plans for major projects to evaluate key uncertainties and provide resolution alternatives, analyzed data for geostatistical validation including petrophysical evaluations, and correlated wells, interpreted logs and validated geologic interpretations. He is competent using Petrel, GOCAD, Geoprobe, DecisionSpace Suite, Petrosys, VoxelGeo GIS, and Seisworks, Petra, Insight Earth, AASPI software. Scott earned his B.S. degree in Geoscience with an emphasis in Geophysics from the University of Utah, and his M.S. degree in Geology from Brigham Young University.
