Engineer-Well II

Primary purpose:

As a Wells Engineer II, you will provide well engineering support for Tallgrass's Class VI CO2 storage, underground gas storage operations, and future well and subsurface-related projects. You will work closely with cross-functional teams to ensure safe, compliant, and efficient well operations throughout the full well lifecycle, from drilling and completions through intervention, monitoring, and abandonment. This role combines office-based engineering with significant field presence to support ongoing operations and project execution. The ideal candidate is a motivated early-career professional eager to develop technical expertise and contribute to Tallgrass's growing subsurface asset portfolio.

 Essential duties and responsibilities:

• Support all phases of well engineering activities including drilling, completions, workovers, interventions, and plug & abandonment (P&A) operations for CO2 storage and gas storage wells.

  • Assist in the design, planning, and execution of well construction and maintenance programs, ensuring alignment with engineering standards and regulatory requirements.

  • Develop and maintain well integrity management programs, including monitoring, testing, and documentation of well barrier status.

  • Support workover and intervention planning by preparing procedures, cost estimates, equipment specifications, and operational timelines.

  • Assist with monitoring well operations, ensuring data quality and system reliability for CO2 storage and gas storage surveillance programs.

  • Collaborate with reservoir engineering, field operations, and project management teams to optimize well performance and troubleshoot operational issues.

  • Prepare well designs, casing and cementing programs, and completion schematics for new wells and remediation projects.

  • Support compliance with applicable regulations including API RP 1171, PHMSA Underground Natural Gas Storage rules, and EPA Class VI injection well requirements.

  • Participate in field operations as needed, including well site supervision, witnessing critical operations, and coordinating with contractors and service companies.

  • Maintain accurate well records, databases, and engineering documentation in systems such as WellView and OpenWells.

  • Analyze well performance data using tools including LOWIS and SCADA systems to identify trends and recommend optimization opportunities.

  • Contribute to feasibility studies, risk assessments, and project planning for future well and subsurface development initiatives.

  • Communicate technical information clearly through written reports, presentations, and verbal updates to internal teams and management.

  • Maintain a strong safety culture by adhering to and promoting all safety policies and procedures during office and field activities.

Minimum requirements:

Education:

• Bachelor of Science in Petroleum Engineering, Mechanical Engineering, or related Engineering discipline.

Experience/Specific Knowledge:

• Minimum of 2-5 years of experience in well engineering, drilling, completions, or related upstream/midstream operations roles.

• Working knowledge of well construction fundamentals including casing design, cementing, completions, and artificial lift systems.

• Familiarity with well integrity management principles and regulatory frameworks.

• Exposure to workover, intervention, and/or plug & abandonment operations.

• Understanding of CO2 injection wells, gas storage wells, or similar subsurface operations preferred.

• Ability to interpret well logs, completion diagrams, and well schematics.

• Willingness and ability to perform significant field work, including travel to well sites and extended periods at field locations as operational needs require.

• Willingness to work non-traditional hours to support field operations and emergency response.

• Strong analytical and problem-solving skills with attention to detail.

• A team player with proven communication skills, capable of working effectively with technical and non-technical personnel.

• Ability to work with moderate supervision while being driven to produce results at both an individual and team level.

Certifications, Licenses & Registrations:

• Must possess and maintain a valid driver's license and a driving record satisfactory to the company and its insurers (required for frequent travel to field operations).

• Well Control Certification (IWCF or IADC WellCAP) preferred or willingness to obtain within first year.

Competencies, Skills & Abilities:

• Petroleum/Well Engineering fundamentals.

• Well control principles.

• Well integrity assessment.

• Workover and intervention planning.

• Basic nodal analysis (inflow/outflow).

• Familiarity with pressure testing and well diagnostics.

• Experience with well engineering software and databases.

• Ability to read and interpret engineering drawings, P&IDs, and well schematics.

Working Conditions:

• Combination of office environment (Lakewood, CO) and field operations at well sites; field work is a significant component of this role and may require 25-50% travel depending on project activity.

• Field locations may include remote areas with exposure to industrial equipment, high-pressure systems, and potential hazards associated with well operations.

• Required to carry a cell phone and be available to respond during working and non-working hours.

• The successful candidate will be required to clear a drug screen and a complete background check, including credit report for certain positions, after an offer has been extended and prior to being employed.

Supervisory Responsibility:

• None

Compensation:

• The annual salary range for this position will be $96,400-$144,600/yr.
