About this role

The Senior Petroleum Geologist leads prospect generation and field evaluation by integrating geologic, petrophysical, and geophysical data to define drillable opportunities and optimize development plans. This role builds basin and play models and prepares resource and reserve estimates under accepted frameworks.

Day-to-day work involves producing clear maps, cross sections, and static reservoir models to guide well placement and completion strategy. The geologist partners with reservoir, drilling, and production teams to align subsurface interpretations with economics, schedules, and risk mitigation.

The position serves Tribal leadership, government partners, and industry stakeholders through high-quality technical reports and executive briefs. It requires frequent travel to Indian Reservations across the continental U.S. and Alaska to conduct fieldwork, collaborate with Tribal leaders, and oversee project activities.

This senior role mentors junior staff, upholds rigorous QA and safety practices, and formulates strategic plans for the development of oil, gas, and other mineral deposits on Indian lands. The work directly impacts resource management and provides opportunities to engage with diverse technical and community partners.
