  • Build & maintain high resolution subsurface models that capture characteristic structural complexity, rock-fabric heterogeneity, & rapid facies changes
  • Recommend drilling targets & development plans for multi well pads, including bench selection, landing depth, & spacing/stacking recommendations
  • Assess reservoir connectivity, depletion, & parent/child interference
  • Analyze offset well results & integrate geological models with reservoir & completions engineering to guide analog selection & type curve refinement
  • Provide real time support as needed for geosteering active wells
  • Develop well prognoses, geo hazard maps, & structural predictions for operational planning & participate in drilling design reviews
  • Conduct post drill analyses to validate interpretations & update models accordingly
  • Work closely with reservoir engineers on depletion modelling, pressure analysis, & EUR forecasting
  • Coordinate with execution teams to minimize NPT & optimize designs via integrated rock mechanics interpretations
  • Present technical findings, risks, & development recommendations to asset & technical leadership & multi-disciplinary teams

Requirements

  • Bachelor’s degree in Geology, Geosciences, or related discipline (master’s preferred)
  • Minimum 5 years of unconventional development geoscience experience, with direct experience in the Delaware Basin strongly preferred
  • Proficiency in subsurface interpretation tools (e.g., Petrel & Kingdom)
