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 Digital Petrographer to join Geological Operations Department.

Saudi Aramco is embarking on a program to develop its world-class resources and is seeking a professional Digital Petrographer with a broad and deep of knowledge, skill and experience in geological, geochemistry, mineralogical and petrographic background to work on different types of rocks and minerals to drive lab experimental facility, plan, supervise and manage laboratory rock imaging and testing, interpret the data to assess reservoir quality and diagenesis. Experience with analyzing petrographic slides samples (core, cuttings and outcrop) and the acquisition and QC'ing of other results including scanning electron microscopy and quantitative-based analysis as well as orthoscopic and conoscopic observations is also required. Integration of results with core analysis data, cathodoluminescence, fluid inclusion, SEM, XRD, XRF, X-ray Microscopy, chemostratigraphy, radiometric dating, biostratigraphy, etc. to provide analysis of well data in terms of facies, sedimentary architecture, isopach, depositional environment and rock properties. Of primary interest is an ability to assess and integrate internal rock fabric (structural physical properties), diagenetic history and provenance to support reservoir characterization and calibration of rock attributes. An ability and willingness to mentor co-workers and young professionals in applying petrographical and image analysis principles to wider geological understanding.

The successful candidate will also be familiar with petrophysics, clastic sedimentology and sequence stratigraphy, structural geology, have knowledge of wireline logs, conventional and special core analysis practices. Saudi Aramco's position as a world leading hydrocarbon explorer and producer offers unique opportunities for Petrographer to realize their full technical potential in this developing discipline.

Key Responsibilities

You will be expected to perform the following:

Managing lab data planning, acquisition and interpretation programs for various types of lab imaging instruments (slides imaging, scanning electron microscopy, X-ray microscopy, etc.)

Provide advanced geological studies to support long- and short-term Saudi Aramco operations. The responsibilities will include:

  • Rock samples selection to characterize rock heterogeneity.
  • Imagery data description , interpretation and quality control
  • Quantitative-based imagery data analysis in digital formats.
  • Preparation detailed reports in multiple formats
  • QCing and interpreting 2D and 3D image analysis.
  • Data integration with lab results; e.g., CCAL, SCAL, MICP, XRF etc.
  • Collaborating effectively with other team members within a multidisciplinary Group.
  • Ongoing collaboration with industry leaders on the evolution of new petrographic imaging techniques and technologies.


Minimum Requirements

As the successful candidate, you will hold a Bachelor Degree in Geology, Petroleum Engineering, Geophysics or Physics. An advanced degree in rock digital imaging / petrology / petrography is essential and will reduce prerequisite work experience stated below by a Master's Degree or a Ph.D. holder.

Fifteen years of experience, including at least seven years on challenging digital imaging and petrography analysis issues, preferably related to evaluation and/or flow simulation of clastic reservoirs. Proven track record in relevant discipline as evidenced by previous work such as publications in the peer-reviewed scientific literature/conferences, etc.

Familiarity with different types of rock analysis instruments, including microscopes, XRD, XRF, X-ray microscopy, scanning electron microscopy tools and petrography software (Petrog Application).

Expertise in acquisition, QC and use of core-derived petrophysical properties (special and standard). Geological software skills (Petrel, Geolog, OpenWorks / DSS) preferred.

Hands on experience with advanced image analysis tools (ZEN, Atlas, PerGeos, GeoDict, DragonFly, etc.).

Expertise in the machine learning and AI technologies application for imagery data interpretation.

Peer-reviewed, published scientific articles in clastic petrography and diagenesis, sedimentology, reservoir geology, and / or unconventional plays a plus.

Core to wireline log data integration and interpretation. Excellent communication skills.

Fluent in written and spoken English.
