About the Job

Requirements

  • A master's degree or equivalent/higher with a minimum GPA of 6.5 or equivalent from a recognized university in Geology, Earth Sciences, Petroleum Geoscience, or related disciplines is required.
  • At least 3 years of industry experience in reservoir quality evaluation, sedimentology, petrography, or related subsurface characterization activities supporting upstream oil and gas operations is required.
  • Strong understanding of sedimentary geology, depositional systems, diagenesis, and pore-network evolution in conventional and unconventional reservoirs is required.
  • Hands-on experience with core description, petrographic analysis, thin section interpretation, and point counting techniques is required.
  • Experience integrating reservoir quality datasets with well logs, seismic data, and reservoir performance information is required.
  • Working knowledge of basin modeling and reservoir quality prediction workflows is required.
  • Experience using industry-standard software such as Touchstone, PetroMod, or equivalent geological and basin modeling applications is required.
  • The role requires proficiency in English.

Responsibilities

  • Define project objectives, work scopes, and deliverables in collaboration with the global Reservoir Quality community and Business Units.
  • Analyze sediment properties, depositional facies, textures, and sedimentary structures to reconstruct depositional environments and reservoir evolution.
  • Perform thin section descriptions, petrographic analysis, and point counting to identify mineralogy, textures, pore systems, and diagenetic features impacting reservoir quality.
  • Evaluate porosity, permeability, and diagenetic controls within sedimentary facies, and integrate findings with reservoir performance and production data.
  • Conduct 1D basin modeling studies to predict reservoir quality evolution and property changes under varying burial and subsurface conditions.
  • Integrate reservoir quality datasets, including cores, cuttings, petrographic data, well logs, and seismic interpretations, to understand structural and stratigraphic controls on reservoir properties.
  • Develop and maintain reservoir quality models that characterize heterogeneity and support geological, petrophysical, and reservoir simulation workflows.
  • Provide reservoir quality insights to optimize well placement, field development planning, and long-term reservoir management strategies.
  • Evaluate, quality check, and interpret petrographic and reservoir quality reports from external laboratories and vendors.
  • Collaborate with petrophysicists, geophysicists, reservoir engineers, and other geoscience disciplines to build integrated subsurface models.
  • Apply reservoir quality workflows and geological characterization methodologies to low-carbon opportunities, including Carbon Capture and Storage projects.
  • Support the development, testing, and implementation of new reservoir quality workflows, tools, and technologies to improve efficiency and consistency across projects globally.

Desired Qualifications

  • Experience supporting Carbon Capture and Storage projects or other low-carbon subsurface applications is desirable.
  • Knowledge of statistical methods, data analytics, programming, or machine learning is an added advantage.

About the Company

ExxonMobil

Produces oil, gas, fuels and chemical materials

ExxonMobil produces oil and natural gas and manufactures fuels, lubricants, and chemicals for transport operators, industrial customers, and consumers around the world. Its businesses span resource exploration and production, refineries that turn crude oil into fuels, and plants that make plastics and other chemical materials. The company sells products through wholesale supply agreements and the Exxon, Esso, and Mobil brands, including motor oils for vehicles and machinery. It also sells services that capture, transport, and store industrial carbon dioxide underground. The merged company formed in 1999 from Exxon and Mobil, with roots in earlier oil businesses, and is headquartered in Spring, Texas.
