With our 9/80 feature you get time off every other Friday when you work at least 80 hours over the preceding nine days.



Hess is seeking an experienced development and production geologist with a minimum of 5+ years’ reservoir modeling expertise to join its Houston-based, non-Operated, Guyana Developments Subsurface team, reporting to the Subsurface Manager.  The successful candidate will become a pivotal member of an integrated, multi-disciplinary, subsurface team whose responsibilities include reservoir modeling and characterization, reserves forecasting, data integration and analyses, operations, and field development planning for development projects.  A grasp of statistics/geostatistics and probability is essential previous experience working with uncertainty modeling is desirable.



Responsibilities include, but not limited to:

  • Collaborating with the team’s reservoir engineers to build high quality, integrated static reservoir models that synthesize all available subsurface data to support field development and history matching efforts. Key focus areas include:
    • Conducting and supervising integrated multi-disciplinary reservoir characterization studies to improve the geological understanding of the target reservoirs and inform geomodel parameterization of reservoir models.
    • Utilizing uncertainty modeling to build and maintain a range of static models to capture key static and dynamic uncertainties.
    • Support the corporate reserves forecasting and booking processes through the creation and maintenance of SEC-compliant geomodels for STOIIP assessments.
    • Conduct and participate in subsurface Peer Reviews and internal technical reviews.
  • Monitoring and reporting of ongoing development well operations. Activities will include picking formation tops, making initial geological interpretations of incoming data, including well logs and formation pressures. Reviewing results and providing updates to reservoir characterization and making future recommendations for development.
  • Seek opportunities to add value to future developments through the identification of new appraisal/development/infill opportunities, smarter depletion options, or cost reductions.
  • Effectively communicate results of subsurface assessments to Hess management and Joint Venture partners. Work with the team to identify and promote value creation opportunities and influence future development plans.
  • Lead, coach, and mentor less experienced staff.
  • Collaborate within the Hess geomodeling community to identify and promote recommended practices across the company.
  • This is an ideal role for an experienced, innovative, and ambitious development geologist who wishes to contribute to Hess’s continued success in the world-class Guyanas Basin. 



  • 10+ years of practical petroleum geoscience experience working for an operator across multiple value chains.
  • 5+ years’ experience or more in applied geomodeling with focus on practical application of geostatistics and uncertainty analysis to conventional deep-water datasets.
  • Strong communication, interpersonal, and teamworking skills are critical.  You must be able to work effectively in a highly collaborative, multi-disciplinary, multi-cultural team environment.
  • A robust and pragmatic understanding of development geoscience and reservoir characterization
    • Geological and petrophysical data, its interpretation, inherent uncertainties, and preparation for geological modeling.
    • Integrating and interpreting multi-disciplinary subsurface (well log, seismic, inversion products, core, pressure etc.) at multiple scales (well, field, and basin scales) to bracket key reservoir uncertainties.
    • Seismic interpretation and the use and limitations of quantitative seismic data in geological model conditioning.
    • Exposure to, and understanding of, ensemble-based modeling approaches is an advantage. A practical understanding of statistics and its application to subsurface data analysis is essential.
    • Previous well planning and well operations experience.
  • The candidate will have a proven track record of:
    • Building and maintaining complex reservoir models using Petrel software. Experience combining uncertainty analyses to produce ranges of models is desirable.
    • Reservoir characterization and static modeling in deep-water clastic depositional systems.
    • Working directly with reservoir engineers to maintain and optimize robust subsurface models, calibrated to all available static and dynamic data, to support field sanction decisions.
    • Using SEC reserves certification and reporting guidelines to assess potential reserves bookings.
  • Strong presentation skills – The ability to communicate clearly and concisely in all business meetings, both internally and externally.
  • A proven ability to deliver high quality, fit for purpose, models in a timely manner.
  • An ability and willingness to mentor and developed junior staff.


Education, Training & Certifications

  • A minimum of an MS in Geoscience or related discipline with formal training courses in various development geological disciplines.
