Course format
The EAGE Interactive online short courses bring carefully selected courses of experienced instructors from industry and academia online to give participants the possibility to follow the latest education in geoscience and engineering remotely. The courses are designed to be easily digested over the course of two or three days. Participants will have the possibility to interact live with the instructor and ask questions.
Education Packages
To help you save on registration fees and better organize your learning path, we are offering Education Packages for all Interactive Online Short Courses and Online EETs. The packages are valid for a period of 12 months, choose between packages of 3, 5 and 10 credits.
Course description
Reservoir modeling provides a set of techniques to create three-dimensional numerical earth models in terms of elastic, petrophysical and dynamic properties of reservoir rocks. Mathematical/physical models of the reservoir are generally uncertain due to the lack of information, noise in data measurements, approximations and assumptions. The course focuses on geostatistical methods for reservoir modeling and uncertainty quantification techniques for reservoir predictions.
It is divided into four main parts: Geostatistical methods for interpolation and simulation; Rock physics modeling; Geophysical inverse problems; Uncertainty quantification.
Uncertainty propagation from measured data, through physical models to model predictions will be studied with a focus on seismic data inversion, static reservoir characterization, structural modeling, dynamic fluid simulation, and time-lapse monitoring. Real case studies will be presented for each topic to illustrate the proposed workflows.
Course objectives
Upon completion of the course, participants will be able to:
- Generate multiple reservoir models;
- Understand physical relations between reservoir and geophysical parameters;
- Evaluate the uncertainty of model predictions.
Course Outline
The following steps in seismic data processing will be discussed:
- Introduction
- Part 1: Review of statistical analysis and probability
- Part 2: Geostatistics and spatial uncertainty
- Part 3: Rock physics
- Part 4: Geostatistics and spatial uncertainty
- Part 5: Seismic inversion
- Part 6: Uncertainty quantification
- Part 7: Visualizing uncertainty
Case studies will be presented for each section.
Participants' profile
The course is designed for employees of oil companies in geophysics and reservoir modeling.
Prerequisites
Participants should have knowledge of basic reservoir modeling concepts and of common geophysical data.
