Company: Saudi Aramco
Skills: Geologist
Experience: 15 + Years
Education: Bachelors/3-5 yr Degree
Location: Saudi Arabia


Req Number: 18736BR

Position Description:
We are seeking a Petrographer to join the Gas Reservoir Characterization Department (GRCD) within our Exploration Organization.
The GRCD is responsible for developing more accurate geological models that account for micro scale data that govern reservoir lateral and vertical changes that directly influence reservoir development.
Your primary role will be to analyze different types of rocks and minerals to assess reservoir quality.

Minimum Requirements:
As the successful candidate you will hold a bachelor's degree in earth science (geology-sedimentology, petroleum geology). An advanced degree is preferred.

You will have a minimum of 15 years of experience, including at least five years on challenging petrography and diagenesis investigations (technique of description and characterization of rocks), preferably related to reservoir characterization, evaluation, and/or modeling, and a strong geological, mineralogical, and siliciclastic petrographic background.

You must demonstrate the ability to assess and integrate internal rock fabric (structural, physical properties), diagenetic history and provenance to support reservoir characterization and calibration of rock attributes.

You should have specific experience in siliciclastic petrology, diagenesis, and reservoir quality analysis.

A proven track record in relevant discipline as evidenced by previous work - as a main investigator - such as publications in the peer-reviewed scientific literature/conferences, etc.

You will be familiar with qualitative and quantitative micro scale analysis, including reservoir diagenesis modeling, and diagenetic influence on reservoir characteristics.

Also required is expertise in acquisition, QC, and use of core-derived petrophysical properties (special and standard), geological software skills (Petrel, Geolog, OpenWorks/DSS) and core to wireline log data integration and interpretation.
Experience with analyzing physical samples (core, cuttings and outcrop), including petrographic slides, orthoscopic and conoscopic observation and integration of results with core analysis data, SEM, XRD, XRF, chemostratigraphy, radiometric dating, biostratigraphy, etc., to provide analysis of well data in terms of facies, sedimentary architecture, isopach, depositional environment, etc., is preferred.

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

Carry out analog and digital analysis of geological data to provide support for geological and sedimentological studies and operational decisions.

Rock sample selection to characterize rock heterogeneity.

Petrographic slide description and interpretation and slide quality control.

Data integration and modeling.

Calibration with lab results; e.g., MICP, XRF, etc.

Interpret rock properties.

Prepare/review reports.

Ongoing collaboration with industry leaders on the evolution of new petrographic techniques and technologies.

About us:
Saudi Aramco's Exploration & Producing (E&P) business line oversees the world's largest reserves of conventional crude oil, and the fourth-largest reserves of natural gas. The Company's reserves portfolio include Ghawar, the world's largest onshore oil field, and Safaniya, the largest offshore field. Company geologists are actively seeking additional reserves in many areas of the Kingdom, offshore in the Gulf and the Red Sea and onshore in the deserts and mountains. Petroleum engineers and earth scientists in E&P work with cutting-edge technology to manage and produce these reserves, including 3D visualization, reservoir simulation and remote geosteering of multilateral wells. The Company's Exploration and Petroleum Engineering Center, or EXPEC, is home to one of the industry's most powerful computer centers. Research and development into subsurface upstream technology is conducted at the EXPEC Advanced Research Center. For more than two decades in a row, Saudi Aramco has been ranked the No. 1 oil company in the world by Petroleum Intelligence Weekly, a testament to the dedication and professionalism of the men and women of Exploration & Producing.
