Subsurface Injection Engineer
About The Position
We are seeking a highly skilled engineer with specialized experience in saltwater disposal (SWD) wells, acid gas injection (AGI) wells, and underground storage–related well operations. The ideal candidate will have deep technical expertise in well design, construction oversight, maintenance and workovers, regulatory compliance, and subsurface geologic interpretation, as well as a solid understanding of injection-related seismicity in the Permian Basin. This role will support full-cycle injection well engineering, providing technical leadership across design, permitting, drilling, completion, workover, and long-term performance optimization.
Requirements
- Bachelor’s degree in Petroleum Engineering, Mechanical Engineering, or a related discipline.
- 10+ years of relevant experience in:SWD and AGI well design and operations Injection well drilling, completions, and workovers Mechanical integrity testing and regulatory reporting Geologic and reservoir interpretation Seismicity‑sensitive operational practices in the Permian Basin
Nice To Haves
- PE license preferred but not required.
Responsibilities
- Injection Well Engineering & Design
- Design SWD and AGI wells including casing, tubing, packer systems, cementing programs, and corrosion mitigation.
- Perform injection modeling, injectivity analysis, pressure evaluation, and containment assessment.
- Develop drilling, completion, and construction specifications and support field execution.
- Apply engineering standards consistent with industry practices observed in underground storage and injection well operations.
- Operations, Maintenance & Workovers
- Lead mechanical integrity test (MIT) planning and execution.
- Develop workover procedures for injection wells, perform diagnostics, troubleshoot flow and pressure anomalies.
- Oversee remedial cementing, tubing repairs, packer replacement, and injection system optimization.
- Support well maintenance functions commonly required in storage and injection facilities.
- Regulatory Compliance & Permitting
- Ensure compliance with Texas Railroad Commission (RRC), EPA UIC Class II program, and other regulatory bodies.
- Prepare and file permit applications, completion forms, MIT documentation, pressure reports, and compliance filings.
- Maintain expert knowledge of statewide injection/disposal regulations.
- Subsurface Geologic Interpretation
- Collaborate with geologists to evaluate injection intervals, reservoir quality, containment risk, fracture gradients, and pressure‑front movement.
- Interpret logs, map structural and stratigraphic trends, and integrate geomechanical considerations into well design.
- Seismicity Monitoring & Risk Mitigation
- Monitor seismicity trends in the Permian Basin associated with injection activity.
- Implement pressure management strategies, depth adjustments, rate reductions, and operational changes based on seismic response area (SRA) directives.
- Support seismic risk analysis to ensure safe, compliant injection operations.
- Cross‑Functional Collaboration
- Work closely with Operations, HSE, Regulatory, and Subsurface Teams.
- Provide engineering leadership during field operations, project planning, failure analysis, and equipment specification.
- Support budgeting, cost forecasting, and project controls.
- All other duties as assigned
