Petroleum Systems Analyst

Job Description and Requirements

As the successful candidate, you will hold a Bachelors’ degree in Geosciences in Petroleum Geoscience/Geochemistry or closely related Earth Science discipline. A Masters or PhD degree is preferred. 

You will have a minimum of 10 years' experience with a major oil/gas company, and a strong understanding of petroleum systems in tectonically active as well as salt basins.

You will have knowledge of industry software such as PetroMod and Trinity, as well as Petrel.

Duties & Responsibilities:
You will be expected to perform the following:


  • Collaborate within the regional and asset teams and integrate a suite of geological, geophysical, and engineering data to evaluate the hydrocarbon potential on the regional scale.
  • Carry out quality assurance of legacy data and provide petroleum systems context for new and existing plays within the Red Sea.
  • Perform source rock geochemical analysis including (TOC, Pyrolysis, GC, GCMS, Kerogen microscopy, Vitrinite reflectance ….etc.) and fluid-source correlation studies using Biomarkers, isotopes and oil fingerprinting.
  • Conduct 1D-3D integrated basin modelling studies to 
  • evaluate thermal history, access to charge and retained volume for each prospect.
  • Follow up our daily operations and provide a real-time support for gas analysis for a number of wells. 
  • Evaluate the current mudstone database and analyze samples for seal capacity prediction, and estimated column heights.
  • Integrate water chemistry data into 3D migration models and make predictions for the hydrodynamic fluid flow, hydrocarbon migration and entrapment.
  • Follow up PVT analysis for bottom hole samples and provide interpretation for fluid types and expected CGRs. 
  • Ensure PVT results integration into 3D models to predict fluid phase and property for next prospects.
  • Design acquisition programs for geochemical sampling including IsoTube, IsoJar samples for next wells, and provide interpretation for the GC and Isotope results.
