• Regularly interface with operators to ensure timely and accurate data sharing
• Incorporate historical performance lookbacks into forecast calibration

Qualifications:

• Bachelor’s degree in Petroleum Engineering or a related technical/quantitative field
• Minimum 8 years of industry experience, with a focus on reserves analysis, production forecasting, and economic evaluation
• Proficient with ComboCurve (or similar platforms such as ARIES or PHDWin), Spotfire, and data from Enverus, IHS, or public regulatory databases
• Comfortable managing multiple workflows and shifting priorities in a small, collaborative team
• Strong communication skills and attention to detail
• Delaware Basin experience and familiarity with non-operated portfolios are preferred
