Sr. Staff Geologist

TG Natural Resources LLC; Houston (TX); On-site; USD 120,000 - 180,000; Full time

Job summary

TG Natural Resources LLC seeks a Staff Geologist to lead integrated geological interpretation and development planning in Texas. You will build static models, contribute to field development strategies, and support operational decisions with cross‑functional teams including engineering, land, and operations.

The role requires 8–10 years in development geology, expertise in well planning and geosteering, and proficiency with Petra/Kingdom and visualization tools.

Qualifications

• Master’s degree in Geology or Geoscience required.
• 8–10 years of development geology experience in unconventional or tight-rock plays, East Texas/Ark-La-Tex preferred.
• Experience in well planning, ops geology, and geosteering with vendor coordination.
• Ability to produce OOIP/GIIP volumetrics with uncertainty ranges for AFE and plans.
• Proficiency with visualization tools Spotfire and Power BI.
• Strong communication and cross-disciplinary collaboration skills.

Responsibilities

• Perform integrated geological interpretation using well logs, cores, seismic attributes, and production data to characterize reservoir quality and continuity.
• Build and maintain static geological models, maps, and property grids with OOIP/GIIP ranges for development decisions.
• Develop stratigraphic/structural frameworks and cross-sections to support field development plans.
• Create pre-spud geologic prognoses and targets for horizontal wells.
• Provide operations geology and geosteering support with vendors and real-time target updates.
• Integrate drilling events and LWD/MWD data to update interpretations and optimize decisions.
• Lead post-well lookbacks to refine models and future well designs.
• Support reservoir surveillance to inform spacing, stacking, and lateral placement decisions.
• Assist in evaluating non-operated proposals and competitor activity.

Job description

Description

The Staff Geologist supports subsurface and asset development programs through integrated geological interpretation, well planning, and operational collaboration. This role delivers high-quality geological models, actionable development recommendations, and operational support that help drive efficient drilling, reservoir understanding, and disciplined field development planning. The geologist will work closely with engineering, land, and operations teams to advance both operated and non-operated opportunities.

Responsibilities

• Perform integrated geological interpretation using well logs, cuttings, core, seismic attributes (where available), and production data to characterize reservoir quality and continuity.
• Build and maintain static geological models, maps, and property grids, delivering OOIP/GIIP volumetrics with uncertainty ranges for development decisions.
• Develop and refine stratigraphic/structural frameworks and generate cross-sections supporting landing zone selection and field development plans.
• Create pre-spud geologic prognoses, hazard notes, and structural/stratigraphic targets for horizontal wells.
• Provide operations geology and geosteering interface support, coordinating with vendors and delivering real-time target updates to ensure accurate well placement.
• Integrate drilling events, mud log shows, gas data, and LWD/MWD responses to update interpretations and optimize on-the-fly decision-making.
• Lead/participate in post-well lookbacks, reconciling drilling results, reservoir quality, and geo-mechanical performance to refine models and future well designs.
• Support reservoir surveillance by analyzing production trends, completions interplay, and offset well performance to inform spacing, stacking, and lateral-placement decisions.
• Assist in evaluating non-operated proposals and competitor activity to advise performance drivers and development strategy.
• Ensure high-quality geological data management, including tops, markers, grids, correlation frameworks, and integration with corporate datastores.
• Contribute to workflow standardization, digital efficiency improvements, and enhancements to data-quality governance supporting rapid decision-making.
• Work closely with reservoir, drilling, completions, and land teams to generate pre-spud and post-spud reviews aligned with TGNR’s development objectives.
• Prepare and deliver high-quality maps, technical reports, volumetric summaries, and recommendations for leadership reviews, partners, and internal decision gates.

Qualifications

• Master’s degree in Geology or Geoscience required.
• 8–10 years of experience in development geology within unconventional or tight-rock plays, ideally with exposure to East Texas/Ark-La-Tex basins.
• Demonstrated experience in well planning, ops geology, and geosteering interaction (vendor coordination, target corrections).
• Proficiency with Petra and/or Kingdom for mapping, correlation, and directional planning; experience with StarSteer or ZoneVu preferred.
• Ability to produce volumetrics (OOIP/GIIP) with uncertainty ranges and incorporate results into AFE packages and development plans.
• Familiarity with Spotfire, Power BI, or similar visualization tools.
• Strong communication skills with ability to present clearly to multidisciplinary teams and management.
• Effective time-management and organizational abilities; capable of handling multiple concurrent priorities.
• Collaboration mindset and willingness to support operations during off-hours if drilling activity requires.
