Aramco energizes the world economy.

Aramco occupies a unique position in the global energy industry. We are the world’s largest producer of hydrocarbons (oil and gas), with the lowest upstream carbon intensity of any major producer. 

With our significant investment in technology and infrastructure, we strive to maximize the value of the energy we produce for the world along with a commitment to enhance Aramco’s value to society.

Headquartered in the Kingdom of Saudi Arabia, and with offices around the world, we combine market discipline with a generations’ spanning view of the future, born of our nine decades experience as responsible stewards of the Kingdom’s vast hydrocarbon resources. This responsibility has driven us to deliver significant societal and economic benefits to not just the Kingdom, but also to a vast number of communities, economies, and countries that rely on the vital and reliable energy that we supply.

We are one of the most profitable companies in the world, as well as amongst the top five global companies by market capitalization.


We are seeking a CO2 Storage Geomodeler to join Western Area & Strategic Exploration Department. The Western Area & Strategic Exploration Department (WA&SED) responsible for the hydrocarbon & non-hydrocarbon resources through strategic & sustainable exploration programs that integrate the best talent, optimal processes and leading-edge technologies in a safe and cost-effective manner. A qualified candidate will be part of a competent team of geoscientists, work collaboratively to maintain a healthy portfolio for CO2 storage. Technical responsibilities include all aspects of advanced data analysis, characterization, and 3D Modeling by utilizing available geological, geophysical, petrophysical, fracture analysis and Dynamic modeling data to evaluate and generate numerical sink models for CO2 Storage, whether in Saline aquifers or sequestration in mafic/ultramafic hard rocks.


The candidate will be required to perform the following:

  • Generate Numerical Subsurface Models by utilizing all the available G&G data, geomechanical, petrophysical, and dynamic data to identify and quantify CO2 Storage sinks, Injectivity Assessment, Seal Integrity, and Depth Evaluation under Uncertainty and Risk Considerations. Evaluate Trapping mechanisms including Structural, stratigraphic, Residual, Solubility, and Mineral trapping
  • Perform 3D Structural, stratigraphic, Petrophysical, and Fluid Saturation Modeling by incorporating leading-edge methodologies and workflows.
  • Build Geomechanical Models for Discrete Fracture Network incorporating Rock and Field Stress analysis for full evaluation of Ground Deformation, Fault Reactivation, induced seismicity, and fracture propagation.
  • Evaluate leakage risk associated to static geological properties and dynamic conditions in time.
  • Perform Volumetric uncertainty analysis under uncertainty.

Minimmum Requirements

As a successful candidate, you would need to hold a bachelor or higher degree in Geology or Geophysics.

  • 15 years of experience in formation description, characterization and geomodeling of Clastic and Carbonate reservoirs with demonstrated track record associated to CCS Projects.
  • Ability to integrate all available Geological, Geophysical, Petrophysical, Sedimentological, and reservoir engineering information for advance 3D Geological Modeling for reservoir architecture, Volumetric analysis and flow behavior.
  • Familiar with Software solutions for Interpretation and Integration of all geological, geophysical, geomechanical, and dynamic data (DSG, Petrel, RMS, Petrosys, Geolog, Teclog,etc).
  • Ability to generate a 3D geological model for sink characterization, for CO2 Saline aquifers or Carbon chemical mineralization in mafic/ultramafic rocks, utilizing limited sparse data with multiple scenarios, uncertainty analysis and risk analysis
  • Strong knowledge of statistical methods necessary to distribute facies and petrophysical properties into a 3D geological model.
  • English language fluency with the capability to communicate verbally and in writing.
  • Excellent presentation skills.

Working environment

Our high-performing employees are drawn by the challenging and rewarding professional, technical and industrial opportunities we offer, and are remunerated accordingly.

At Aramco, our people work on truly world-scale projects, supported by investment in capital and technology that is second to none. And because, as a global energy company, we are faced with addressing some of the world’s biggest technical, logistical and environmental challenges, we invest heavily in talent development.

We have a proud history of educating and training our workforce over many decades. Employees at all levels are encouraged to improve their sector-specific knowledge and competencies through our workforce development programs – one of the largest in the world.
