Job description

COMPANY PROFILE

Diversified Gas & Oil Corporation (“DGOC”) is a wholly‑owned subsidiary of Diversified Energy Company PLC, a US‑based company listed on the New York Stock Exchange (NYSE) and London Stock Exchange (LSE) under the ticker symbol “DEC”. Diversified Gas & Oil Corporation (DGOC) is an established owner and operator of producing conventional and unconventional natural gas & oil wells and midstream pipelines and compression stations concentrated in the Appalachian Basin in the United States. Headquartered in Birmingham, AL, our field operations are located throughout the Appalachian Basin in the states of Tennessee, Kentucky, Virginia, West Virginia, Ohio, and Pennsylvania. In 2021, Diversified announced our expansion into our Central Regional Focus Area, which includes producing areas within Louisiana, Texas, Oklahoma, and Arkansas.

POSITION SUMMARY & RESPONSIBILITIES:

The Geology Intern will support Diversified’s Subsurface team by evaluating wellbore utilization opportunities across Texas and New Mexico. The intern will focus on identifying remaining reservoir potential, assessing recompletion and uplift opportunities, and helping expand the company’s inventory of wells with remaining utility—whether through continued production, recompletion, injection, disposal, or gas storage.

This role is ideal for a geology student interested in reservoir characterization, wellbore optimization, and applied geoscience in mature fields. The intern will gain hands‑on experience with subsurface mapping, wellbore analysis, and multidisciplinary collaboration with reservoir engineers and data teams.

Wellbore Utilization Project (Primary Internship Focus)

• Evaluate wells withremaining uplift potentialorremaining reservoir utility, including:
  • Recompletion/refrac opportunities in the producing zone
  • Conversions to injection, disposal, or gas storage wells
  • Utility in shallower zones where applicable
• Maintain and continually update aninventory of wellscategorized by potential future use.
• Work with reservoir engineers and production engineers to track wells with:
  • Remaining reserves
  • Recompletion or workover potential
  • Plug‑and‑play suitability for injection or storage
  • Economic factors that impact the utilization decision

Subsurface Mapping & Reservoir Characterization

• Map reservoirs across Texas and New Mexico to determine:
  • Structural and stratigraphic framework
  • Reservoir continuity and thickness
  • Remaining hydrocarbons in place
• Create structure, isopach, net pay, and reservoir quality maps using log and production data.
• Identifyanalog productionto support recompletion and economic uplift analysis.

Remaining Reserves & Economic Support

• Estimate remaining hydrocarbon volumes‑in‑place using decline data, log data, and analog comparisons.
• Assist engineers by compiling subsurface inputs for recompletion economics (type curves, analogs, depletion mapping).

Gas Storage & Injection Feasibility Analysis

• Mapdepleted formationsto determine suitability for:
  • Gas storage
  • Conversion to Class II injection or disposal
• Evaluate log data, pressure histories, and production trends to assess containment and injectivity.

Data & Project Management (Petra Focus)

• Organize, clean, and maintainPetra projectsfor assigned fields.
• Ensure well data, log curves, tops, surveys, and production histories are accurate and complete.
• Assist in building project templates and subsurface data workflows used by the geology team.

Cross‑Functional Collaboration

• Work closely with:
  • Reservoir Engineers(reservoir potential assessments)
  • Production Engineers(recompletions economic evaluations)
  • Regulatory(permitting requirements for intended wellbore use)
  • Land(determine ownership is proposed formations)
• Participate in team reviews, utilization planning discussions, and field development meetings.

POSITION REQUIREMENTS:

Required

• Actively enrolled in a Bachelor’s or Master’s program in Geology, Geophysics, Earth Science, Petroleum Geoscience, or related field.
• Strong interest in reservoir characterization and applied subsurface geology.
• Ability to work with log data, production history, and mapping software.
• Proficiency with Excel and basic data management.
• Strong analytical skills and attention to detail.

Preferred

• Experience withPetra, ArcGIS Pro, or similar subsurface software.
• Familiarity with well logs, basic petrophysics, and reservoir behavior.
• Prior internship or hands‑on geoscience project experience.
• Exposure to operations in mature basins (Permian, Central Basin Platform, Texas Gulf Coast, NM shelf, etc.).

We value safety, production, efficiency, and enjoyment in our work.

Office Physical Requirements and Working Conditions:

• Prolonged periods working at a desk in front of a computer.

Additional Requirements:

• Must be able to lift up to 15 pounds at a time.
