Senior Biostratigrapher: Oil and Gas Exploration

Ian Martin Group; Spring (TX); Presencial; USD 96.000 - 165.000; Jornada completa

Descripción de la vacante

The Ian Martin Group is seeking a Biostratigrapher for a contractor role with a client in the oil and gas sector in the United States (Texas region). The candidate will bring advanced biostratigraphic expertise, lead integration of fossil data with well logs and seismic data, and guide stratigraphic interpretations for pre-drill and real-time support.

The role requires a Master’s or PhD in geology or related discipline and a proven track record of high-impact stratigraphic studies, mentoring

Formación

• Master’s degree or PhD in geology, paleontology, micropaleontology, palynology, stratigraphy, or a related discipline.
• 10+ years of oil and gas industry experience, including exploration, development, and/or well operations.
• Advanced taxonomic expertise in at least one major fossil discipline, with working knowledge of other biostratigraphic methods preferred.
• Strong understanding of biostratigraphy, chronostratigraphy, sequence stratigraphy, sedimentology, depositional environments, and basin evolution.
• Demonstrated ability to integrate fossil data with well logs, core, seismic, geochemical, and other subsurface datasets.
• Experience delivering single-well, multi-well, field-scale, or regional stratigraphic studies.
• Strong technical judgment, uncertainty assessment, report writing, project management, and multidisciplinary communication skills.
• Ability to mentor junior staff, provide technical assurance, and influence decisions without formal authority.

Responsabilidades

• Provides specialist stratigraphic expertise to oil and gas exploration, appraisal, development, and drilling teams. Using micropaleontology, palynology, calcareous nannofossils, or related fossil disciplines, the role establishes geological age, correlation, depositional environment, and stratigraphic frameworks that reduce subsurface uncertainty and support business and operational decisions.
• Analyzes fossil assemblages from cuttings, core, sidewall core, and outcrop samples; identifies bioevents, unconformities, condensed sections, reworking, cavings, and preservation limitations; develops defensible age and paleoenvironmental interpretations; integrates results with well logs, sedimentology, sequence stratigraphy, seismic interpretation, geochemistry, and regional basin frameworks.
• Designs fit-for-purpose sampling and analytical programs, prepares pre-drill stratigraphic prognoses, and provides operational guidance on formation identification, coring and casing points, section total depth, and stratigraphic position ahead of the bit.
• Assures the technical quality of internal and contractor-generated work, manages external laboratory studies, maintains auditable datasets and reference collections, and communicates interpretation confidence, alternative hypotheses, and business implications.
