Sr. Exploration Geoscientist

Repsol•Houston, TX
•Onsite

About The Position

Repsol is seeking a Sr. Exploration Geoscientist to join its Exploration Americas HUB team, based onsite at the company’s office in The Woodlands, Texas. The role focuses on identifying, evaluating, and maturing hydrocarbon exploration opportunities by integrating geophysical and geological information, primarily seismic and well data. The successful candidate will be a technically self-sufficient explorationist with a proven track record who can independently generate and mature drillable prospects, provide technical assurance, resolve complex subsurface challenges, and transfer critical knowledge across the organization. The role covers the exploration cycle, including opportunity screening, prospect generation and characterization, well planning and drilling support, and seismic acquisition and processing oversight. The geoscientist will evaluate onshore and offshore opportunities, assess petroleum systems and exploration risks, estimate hydrocarbon volumes, and prepare and present technical recommendations to technical and management stakeholders.

  • Bachelor’s degree in Geology or a related field.
  • At least 15 years of relevant hydrocarbon exploration experience covering both onshore and offshore projects.
  • Demonstrated ability to perform highly complex geophysical studies and technically validate work conducted by project teams and external contractors.
  • Demonstrated experience generating, characterizing, and maturing leads and prospects, including volumetric estimation and exploration risk assessment.
  • Advanced structural and stratigraphic seismic interpretation, integrating seismic and well data with geological models.
  • Strong quantitative geophysics expertise, including rock physics, AVO/AVA analysis, seismic attributes, seismic inversion, and property estimation.
  • Experience identifying and evaluating DHIs using the SAAM methodology.
  • Ability to characterize and assess petroleum system elements and integrate them into prospect evaluation.
  • Proficiency in structural modelling, velocity analysis, and depth conversion.
  • Experience preparing exploration well proposals, providing G&G support for well design, monitoring drilling operations, and conducting post-drill evaluations.
  • Working knowledge of seismic acquisition, processing, and post-processing, with the ability to supervise projects and assess data quality against exploration objectives.
  • Strong presentation skills and ability to communicate and defend technical interpretations and recommendations.

  • Prepare technically substantiated exploration well proposals and provide G&G input to well design and planning.
  • Deliver real-time geophysical support during drilling and conduct post-drill evaluations.
  • Supervise borehole seismic activities and support VSP acquisition projects.
  • Contribute to development well proposals when required.
  • Monitor and provide technical support for 2D and 3D land and marine seismic acquisition and processing projects.
  • Coordinate seismic processing and post-processing activities.
  • Perform processing quality control, including illumination studies, multiple attenuation, PSDM/RTM workflows, tomography updates, and mute picking.
  • Ensure seismic products are suitable for interpretation, characterization, and prospect evaluation.
  • Prepare technical reports and presentations documenting interpretations, uncertainties, risks, and recommendations.
  • Present and defend exploration opportunities, prospect evaluations, and well proposals to technical and management stakeholders.
  • Communicate complex technical issues clearly and support technically informed decision-making.
  • Represent the company, where appropriate, in technical forums, professional networks, and industry associations.
  • Contribute technical expertise to bids, licensing rounds, data rooms, and external technical evaluations.
