Geostatistics for Seismic Data Integration in Earth Models

Sunday, 19 January 2014, 0900–1600, Meeting Room 217, QNCC, Doha, Qatar

Instructor: Olivier Dubrule, VP, Geosciences Training and Technical Image, Total, France

Course Outline:

In recent years, the use of geostatistics has spread from the world of reservoir characterization to that of the velocity analysis, time-to-depth conversion, seismic inversion, uncertainty quantification and more generally to that of seismic data integration in earth models. Nevertheless, many geoscientists still regard geostatistics as little more than a statistical black-box. By explaining the concepts and applications, the goal of this course is to clarify the benefits of geostatistics and help spread its use.

The course will cover the use of geostatistics for interpolation (kriging…), heterogeneity modeling, uncertainty quantification (simulation…), and data integration (cokriging, external drift, geostatistical inversion…). A variety of applications and examples will be presented, including velocity mapping, time-to-depth conversion, heterogeneity modeling and seismic data integration in stochastic earth models. The relationships between geostatistics and approaches more familiar to geophysicists, such as filtering or Bayesian methods, will also be discussed, without entering into mathematical details.

This will be a lively course, illustrated by examples, exercises and discussion sessions.

Topics Include:

  • What does the Variogram mean?
  • Different ways of Quantifying Geology
  • Ordinary Kriging
  • External Drift Kriging and Collocated Cokriging for combining seismic and well data
  • Factorial Kriging for filtering seismic data
  • Monte-Carlo Simulation
  • Conditional Simulation
  • Geostatistical Inversion and its latest developments
  • Earth Model Uncertainty Quantification

Who Should Attend:

Petroleum geoscientists and reservoir engineers are the main target of the course. This is a great opportunity for those interested in solving practical problems involving data interpolation, earth modeling, multidisciplinary data integration or uncertainty quantification.

Instructors:

Oliver DubruleOlivier Dubrule obtained a PhD degree in Petroleum Geostatistics with Prof Matheron (the father of geostatistics) at Ecole des Mines de Paris in 1981. He then worked for Sohio Petroleum Company in the USA (1982-1986), Shell International in the Netherlands (1986-1991); since 1991, he has been with Elf and Total, working in France, the UK and Qatar. During his career, he has held a variety of staff and management positions, where he has developed and applied new techniques for reservoir characterization, earth modeling, and uncertainty quantification. Dr. Dubrule is now VP, Geosciences Training and Technical Image at Total in Pau (France). He is a former President of EAGE.

Dr. Dubrule has authored more than twenty papers in the field of geostatistics and earth modeling. In 1991, he received the President’s prize of the International Association of Mathematical Geology, for “Outstanding Contribution to Mathematical Geology by an individual 35 years or younger”. In the last three decades, he organized and chaired a number of events organized by SPE, EAGE, SEG or AAPG. Dr Dubrule is the author of AAPG Course Noted Series #38 “Geostatistics in Petroleum Geology”, and editor (with E. Damsleth) of “Petroleum Geostatistics” as Special Issue of EAGE’s Petroleum Geoscience Journal, published in 2001. The course “Geostatistics for Seismic Data Integration in Earth Models” was the 2003 SEG/EAGE Distinguished Instructor Short Course. The course book has been translated in Russian and Farsi.
