Geosciences and geomodeling

Course facts

Duration: 1 day
Type: Classroom
Certificate: Issued upon completion

Summary

This self-contained course describes ways in which geoscientists (geologists, petrophysicists and geophysicists) can interact with the geomodeler to achieve their team’s goal: building a geomodel which captures how the geoscientists understand the reservoir. This course will explain how the geoscientists’ interpretation influence parameter setup in the geomodeling workflow.

This course is about working as a team. It will show to the geomodeler what he/she can gain from the geoscientists in the asset team. It will also show to the geoscientists where they should fit in when decisions are made about the geomodeling workflow. 2D mapping and contouring will be only superficially discuss as these topics are the focus of a full one-day course from GMDK named From geological contouring to geomodeling.

Duration and Training Method

This one day course is a lecture course. The day will leave plenty of time for discussion between the students and the instructor. The goal is to ensure any given session of this course is tailored as best as possible to the students’ specific work situation. The instructor will remain available for individual discussion in the weeks following the course.

Learning Outcomes

  • Understanding how geology influences cell sizes, mesh orientation and internal layering.
  • Understanding the details, the pros and the cons of pillar gridding and of implicit modeling.
  • Understanding how facies interpretation and petrophysical logs are combined.
  • Understanding how geophysical data are integrated in the geomodeling worklfow.

Course Content

  • Introduction to the course and how its content fits within the whole geomodeling workflow.
  • Example of a project going from depth conversion, structural modeling to 3D facies and petrophysical modeling.
  • Geomodeling and geology – structure. Horizon and fault modeling (implicit modeling, pillar gridding). Example of 3D restoration.
  • Geomodeling and geology – facies modeling. Defining the internal layering of the 3D grid (orientation, cell sizes…).
  • Geomodeling and petrophysics. Do we need facies modeling? Upscaling of petrophysical logs.
  • Geomodeling and geophysics. Depth conversion. Seismic attributes. Input to fracture modeling.

Who Should Attend

Anyone who provides, or anyone who wants to understand how is provided, geological, petrophysical and/or geophysical data and interpretation to an asset team and who needs to be sure they are properly integrated in the geomodeling workflow.

Any geomodeler who wants to better understand how to root his/her decision on workflow setup into the geoscientists interpretation. Any geomodeler who wants to go beyond working with data files provided by the team and dig into working with the interpretation and the vision his/her team has about the reservoir.

Don’t hesitate to contact GMDK if want to discuss how this course could be useful to your specific situation. If GMDK can’t accommodate your specific needs, we will do our best to orient you towards other sources of knowledge.

Prerequisites

Very basic understanding of geomodeling: the general workflow (data gathering, structure, 3D grid building, 3D property modeling) and some understanding about the objects being created.

This course and the course From geological contouring to geomodeling are complementary. But there is no obligation to take both courses as each is self-contained. Students who do want to take both courses can do so in the order that they want.

Instructor

Thomas Jerome. Director of GMDK and 20+year geomodeling expert. See Thomas’ LinkedIn profile for more details.

Self-contained course. Coupled with the other courses of the Geomodeling Program, it will teach to anyone how to become very well versed in the art of geomodeling.
