Senior Petrophysicist / Algeria

Location:
Algiers, Algeria

Job Summary:

We are seeking a
Senior Petrophysicist
to join our
subsurface team in Algiers
, specializing in
advanced petrophysical interpretation, rock typing, saturation-height modeling (Sw modeling), and reservoir characterization
. This role is critical for
integrating well log, core, and seismic data
to deliver high-quality reservoir models that drive field development and production optimization. The ideal candidate will have
deep expertise in complex petrophysical analysis, strong collaboration skills with reservoir characterization and modeling teams
, and a proven track record in
Algerian or similar clastic reservoirs
.

How to Apply:

• Send your
  CV and a brief cover letter
  to [] with the subject:
  "Senior Petrophysicist – Algiers"
  .
• Only shortlisted candidates will be contacted.
• We encourage
  diverse candidates
  to apply.

Key Responsibilities:

1. Advanced Petrophysical Interpretation

• Perform
  detailed petrophysical evaluations
  using
  open-hole and cased-hole logs, core data, and special core analysis (SCAL)
  .
• Develop and refine
  petrophysical models
  for reservoir properties (porosity, permeability, saturation, lithology, and mineralogy).
• Conduct
  uncertainty analysis
  and sensitivity studies to assess petrophysical variability and risk.

2. Rock Typing & Facies Analysis

• Lead
  rock typing studies
  to classify reservoir intervals based on
  lithology, pore geometry, and flow units
  .
• Integrate
  core descriptions, thin sections, and log data
  to define
  electrofacies and hydraulic flow units (HFUs)
  .
• Collaborate with
  geologists and reservoir engineers
  to ensure consistency between petrophysical rock types and dynamic reservoir behavior.

3. Saturation-Height Modeling (Sw Modeling)

• Develop
  saturation-height functions (capillary pressure models)
  using
  core data, well logs, and production data
  .
• Calibrate
  Sw models
  with
  production logs, well tests, and dynamic reservoir data
  .
• Apply
  advanced techniques
  (e.g.,
  J-function, Leverett-J, or machine learning approaches
  ) to improve saturation modeling in complex reservoirs.

4. Reservoir Characterization & Modeling Support

• Work closely with the
  Reservoir Characterization and Modeling team
  to integrate petrophysical data into
  static and dynamic reservoir models
  .
• Provide
  petrophysical inputs
  for
  3D geological and simulation models
  , ensuring consistency with well data and geological concepts.
• Support
  upscaling workflows
  to preserve petrophysical properties in reservoir models.

5. Well Log Quality Control & Data Integration

• Conduct
  rigorous QC of well log data
  (gamma ray, resistivity, density, neutron, NMR, etc.) and
  core-petrophysical integration
  .
• Validate and
  harmonize petrophysical interpretations
  across multiple wells and fields.
• Ensure
  data consistency
  between petrophysics, geology, and reservoir engineering disciplines.

6. Specialized Petrophysical Studies

• Lead
  advanced petrophysical studies
  , including:
• NMR interpretation
  for pore-size distribution and fluid typing.
• Dielectric and spectral gamma ray analysis
  for complex lithologies.
• Fracture and stress analysis
  using image logs (FMI, UBI).
• Evaluate
  low-resistivity pay, tight gas, and unconventional reservoirs
  where applicable.

7. Collaboration with Multidisciplinary Teams

• Work with
  geologists, geophysicists, and reservoir engineers
  to ensure petrophysical interpretations align with
  geological models and dynamic reservoir behavior
  .
• Provide
  petrophysical support
  for
  well planning, completion design, and field development strategies
  .
• Participate in
  integrated reservoir studies
  and
  field reviews
  .

8. Mentorship & Technical Leadership

• Mentor
  junior petrophysicists
  and provide
  technical guidance
  to cross-functional teams.
• Stay updated on
  emerging petrophysical technologies and best practices
  , and implement them in workflows.
• Present
  technical findings and recommendations
  to management and stakeholders.

9. Compliance & Reporting

• Ensure petrophysical interpretations comply with
  company standards and Algerian regulatory requirements
  .
• Document
  workflows, assumptions, and results
  in technical reports.
• Support
  audits and peer reviews
  of petrophysical deliverables.
