Indirect Inversion Schemes: Tomographic and Full Waveform Inversion
Over the past thirty years, characterization of the subsurface has been achieved using various forms of tomographic indirect inversion. This has evolved from isotropic ray-based tomography, into structurally constrained orthorhombic ray-based tomography, and more recently into using the full elastic wave equation (FWI and eFWI). FWI has emerged and developed to the point that is now the main technique of choice for detailed model building and reflectivity estimation for complex geological environments. Use of FWI […]
Introduction to Seismic Interpretation Using Deep Learning
This course aims at introducing the basics and fundamentals of deep learning (DL) and illustrating its values in assisting seismic interpretation.

Duration 8 hours Intended Audience Entry Level Prerequisites (Knowledge/Experience/Education required) The course is designed to […]
Seismic Attributes – from Interactive Interpretation to Machine Learning
An ongoing challenge to seismic interpreters is to identify and extract heterogeneous seismic facies on data volumes that are continually increasing in size. Geometric, geomechanical, and spectral attributes help to extract key features but add to the number of data volumes to be examined. Common interactive analysis tools include crossplotting, interactive animation, and 3D corendering where we examine more than one attribute at a time. When there are more than three attributes, principal component analysis, […]
Reservoir Geophysics: Applications
The objective of the course is to demonstrate how and why geophysics adds value in reservoir management using examples from multiple geological environments (deepwater turbidites, onshore fluvial, near shore deltaics, carbonates). The course is designed to examine and illustrate the dependencies of geology and engineering data on geophysical applications during reservoir management and to expose participants to the variety of geophysical tools used in reservoir work. The participants will become familiar with the application and […]
Petrophysics and Geophysics Relevant to CO2 Enhanced Oil Recovery
In this SEG course the basic physics relevant to CO2 are presented, including the descriptions of gas, liquid and super critical phases (scCO2). Enhanced oil recovery (EOR) was a natural development in the production of hydrocarbons. In this course topics relevant to the utilization of CO2 to enhance oil recovery are presented. CO2 is an especially appealing EOR injection agent. In this SEG course the basic physics relevant to CO2 are presented, including the descriptions […]
Integrating Seismic, CSEM and Well Log Data for Reservoir Characterization
This course will concentrate on three contrasting methods: surface seismic, marine controlled source electromagnetic (CSEM) and well-log data. Improved reservoir management and production optimisation demands require accurate characterisation of reservoir properties and their changes through time. Advances in geophysical data acquisition and interpretation have led to significant improvements in the remote imaging of earth structure and properties. However, when only a single data type is considered, ambiguities in the interpretation can remain. Integration of disparate […]
Geophysical Applications of Time-Frequency Analysis
This course shows how basic knowledge of joint time-frequency (JTF) analysis theory associated with pseudo computer programming can help geoscientists to take full advantage of their real world applications. Several JTF exploration geophysics applications are detailed, like spectral decomposition, data compression, filtering, etc. Starting from Fourier theory review, advanced time-frequency techniques are introduced by showing practical applications and by hands on introductory computer programming. Duration Two days Intended Audience Intermediate level Prerequisites (Knowledge/Experience/Education Required) This […]
