Senior Geomodeller-Geologist
/ Madrid

Location:
Madrid, Spain

Job Summary:

MIDAD Energy
is seeking a
Senior Geomodeller / Geologist
based in
Madrid
to lead
3D geological modeling and reservoir characterization
for our
North Africa projects
(Algeria, etc.). This role focuses on
building robust static reservoir models
, integrating
rock typing, facies analysis, and saturation-height modeling (Sw)
to support field development and reservoir management. The ideal candidate will have
extensive experience in North African basins
, a strong background in
collaborating with petrophysicists and reservoir engineers
, and expertise in
geological modeling software
to deliver high-quality subsurface models.

How to Apply:

• Send your
  CV and a brief cover letter
  to [] with the subject:
  "Senior Geomodeller / Geologist – Madrid "
  .
• 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 (e.g.,
  Petrel
  ).
• Integrate
  well logs, core data, seismic attributes, and geological concepts
  to create accurate reservoir frameworks for North African fields.
• 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
  in North Africa.
• 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 the 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 geomodellers 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/geological experience
  , with a
  strong focus on North African basins
  (Algeria, Libya, etc.).
• Proven experience in rock typing, facies modeling, and Sw integration
  into reservoir simulations.
• Experience collaborating with petrophysicists and reservoir engineers
  in integrated asset teams.
• Familiarity with
  clastic reservoirs
  and
  North African operational standards
  .

Technical Skills:

• Geomodeling software
  :
  Petrel
  (expert level).
