Advanced Geostatistics for Geophysicists

Learn how to enhance the quality of your seismic data to get consistent and reliable velocity volumes

Objective

Geostatistics has become a key tool in geophysics, due to its proven added value for various tasks: seismic data quality control, noise filtering, velocity modeling, time to depth conversion, uncertainty quantification. This course provides a sound understanding of the geostatistical solutions relevant to accomplish these tasks.

Key Features

The capabilities of geostatistics to handle petroleum data characterized by their heterogeneous nature are shown on real cases with a minimum of theory and a maximum of practice.

Who should attend

Geophysicists involved in data interpretation and mapping of surfaces limiting the reservoirs.

Course content

  • Quality Control of seismic data
  • Filtering acquisition artefacts using kriging
  • Multivariate geostatistics and cokriging. Factorial cokriging.
  • The problematic of time to depth conversion: time interpretation, evaluation of the information on velocities and standard models. Integration of wells and seismic data for time to depth conversion
  • 3D seismic data processing: calibration of velocity from stacking velocity cube
  • Introduction to stochastic simulation for assessing uncertainties during velocity modeling, depth conversion and volumetrics.

Prerequisites

The first part of this short course “Basic Concepts of Oil & Gas Geostatistics” covers the fundamental concepts of geostatistics for Oil & Gas and provides an ideal basis for this part.
