Petrophysicist

Description:

Job Summary

The Petrophysicist is a key technical contributor within the Subsurface function, responsible for delivering high quality formation evaluations, petrophysical interpretation, reservoir characterization, and technical assurance across a portfolio of mature and developing fields, including support to the exploration team. The role supports field development planning, reserves maturation, well delivery activities, and surveillance programs. It requires a broad foundation in open/cased hole petrophysics, strong subsurface integration skills, and the ability to influence multidisciplinary teams. The incumbent ensures that petrophysical insights, uncertainty analysis, and data driven interpretations are effectively integrated into subsurface models, depletion planning, well proposals, drilling operations, and long-term reservoir management strategies. The Petrophysicist will collaborate closely with Section Leads and subject matter experts to define and execute the necessary technical work, ensuring all deliverables are fit‑for‑purpose given the subsurface complexity and scale of investment.

Key Responsibilities

Deliver consistent, high quality open hole and cased hole petrophysical interpretations for new wells, workovers, and surveillance operations.
Integrate well logs, core analysis, test data, and production information to build robust reservoir descriptions.
Evaluate reservoir properties (porosity, permeability, saturation, lithofacies, net to gross, etc.) and quantify associated uncertainties.
Update petrophysical models as new data becomes available, ensuring alignment with integrated static and dynamic reservoir models.
Develop and maintain formation evaluation data acquisition plans for new wells, reentries, and surveillance activities.
Recommend optimal logging technologies (LWD, wireline, cased hole tools, core acquisition, imaging, spectral tools, NMR, etc.).
Support real time operations, including log quality control, tool failure mitigation, and rapid decision-making during drilling.
Lead post well reviews, capture lessons learned and ensure continuous improvement in data acquisition workflows. Ensure the integrity, quality, and completeness of all logs, core, and petrophysical datasets.
Collaborate closely with Data Management teams to maintain up to date structured databases and ensure corporate data governance compliance.
Promote the use of analytics, automation, machine learning, and visualization tools to drive efficiency and improve insight generation.
Work closely with geoscientists, reservoir engineers, drilling & wells teams, production technologists, and facility teams to deliver integrated subsurface solutions.
Provide petrophysical input to the Integrated Subsurface Description (ISD), depletion planning, reserves maturation, well placement, and development strategy updates.
Guide the technical framing and prioritization of petrophysical work programs in collaboration with senior advisors and Subject Matter Experts (SMEs).
Manage and provide technical oversight to service companies providing logging, coring, laboratory, and specialized petrophysical services.

Requirements

Deliver consistent, high quality open hole and cased hole petrophysical interpretations for new wells, workovers, and surveillance operations.
Experience in petrophysics, including both open hole and cased hole interpretation.
Demonstrated experience working in integrated, multi-disciplinary teams and influencing technical decisions across functions.
Strong proficiency in interpretation software (e.g., Techlog, Geolog, Petrel, etc.).
Comfortable working with large datasets, complex reservoirs, and uncertain subsurface settings.
Strong understanding of reservoir engineering concepts and integration with static and dynamic models. Proven ability to communicate complex technical concepts to senior leadership and non-technical audiences. Experience working in deepwater or similar complex offshore environments.
Familiarity with digital technologies, data analytics, ML tools, and automated QC workflows

Education & Experience

BSc or BEng, or international equivalent in Engineering or Geoscience degree.
At least 5 years of experience in a similar role.
