Senior Geomodeller-Geologist / Algeria

Location:
Algiers, Algeria

Job Summary:

We are seeking a
Senior Geomodeller
to join our
subsurface team in Algiers
, specializing in
3D static reservoir modeling, rock typing integration, and saturation-height (Sw) modeling
. This role is critical for
building robust geological models
that honor petrophysical, geological, and dynamic data to support field development and reservoir management. The ideal candidate will have
extensive experience in Algerian fields
, a strong background in
collaborating with petrophysicists and reservoir engineers
, and expertise in
incorporating rock types and Sw models into reservoir simulations
.

How to Apply:

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

Key Responsibilities:

1. 3D Static Reservoir Modeling

• Build
  high-resolution 3D static geological models
  using industry-standard software (
  Petrel
  ).
• Integrate
  well logs, core data, seismic attributes, and geological concepts
  to create accurate reservoir frameworks.
• Ensure models capture
  structural complexity, stratigraphy, and sedimentological heterogeneity
  .

2. Rock Typing & Facies Modeling

• Work closely with
  petrophysicists and geologists
  to
  incorporate rock types and electrofacies
  into geological models.
• Develop
  facies models
  that honor
  depositional environments, well data, and geological trends
  .
• Validate rock type distributions using
  well data, analog studies, and dynamic reservoir behavior
  .

3. Saturation-Height (Sw) Modeling

• Integrate
  petrophysical Sw models
  (e.g., J-function, Leverett-J) into
  3D property modeling
  .
• Collaborate with
  petrophysicists
  to ensure
  consistent saturation distributions
  between well logs and geological models.
• Calibrate Sw models with
  production data, well tests, and dynamic reservoir performance
  .

4. Property Modeling & Upscaling

• Distribute
  petrophysical properties
  (porosity, permeability, saturation) using
  geostatistical techniques
  (e.g., SGS, Kriging, object-based modeling).
• Perform
  upscaling workflows
  to preserve geological heterogeneity for reservoir simulation.
• Ensure property models are
  fit-for-purpose
  for dynamic simulation and reservoir management.

5. Collaboration with Reservoir Engineers

• Work closely with
  reservoir engineers
  to ensure geological models are
  suitable for dynamic simulation
  .
• Support
  history matching
  by providing
  realistic geological scenarios
  and uncertainty ranges.
• Iterate on models based on
  simulation results and production data
  .

6. Uncertainty & Risk Assessment

• Conduct
  uncertainty analysis
  (e.g., multiple realizations, sensitivity studies) to assess impact on reserves and production forecasts.
• Provide
  geological input
  for
  volumetric calculations and resource estimations
  .
• Document
  model assumptions, uncertainties, and recommendations
  for management.

7. Data Integration & Quality Control

• Perform
  rigorous QC of input data
  (well logs, seismic, core) and model outputs.
• Ensure
  consistency between geological, petrophysical, and dynamic data
  .
• Validate models against
  production history, pressure data, and well performance
  .

8. Field Development Support

• Contribute to
  field development plans (FDPs)
  by providing
  geological insights and risk assessments
  .
• Support
  well planning and optimization
  by identifying
  sweet spots, baffles, and flow barriers
  .
• Participate in
  integrated reservoir studies
  and
  peer reviews
  .

9. Mentorship & Technical Leadership

• Mentor
  junior geomodelers and geoscientists
  in best practices for reservoir modeling.
• Stay updated on
  emerging geomodeling technologies
  and implement them in workflows.
• Present
  technical findings and recommendations
  to stakeholders.

Qualifications:

Education:

• Master's or PhD in Geology, Petroleum Geoscience, or Reservoir Engineering
  .
• Relevant certifications
  (e.g., SPE, EAGE) are a plus.

Experience:

• 10+ years of geomodeling experience
  , with a
  strong focus on clastic reservoirs
  .
• Proven experience in Algerian fields
  (e.g., Hassi Messaoud, Berkine Basin, or similar).
• Experience collaborating with petrophysicists and reservoir engineers
  to integrate
  rock typing and Sw modeling
  into reservoir simulations.
• Familiarity with
  reservoir simulation workflows
  (e.g., Eclipse, INTERSECT).

Technical Skills:

• Geomodeling software
  :
  Petrel
  (expert level).
• Petrophysical integration
  : Experience with
  Techlog, Interactive Petrophysics, or Geolog
