Most explorationists view seismic data on a workstation to see the geology. Many, however, never have the opportunity to become involved in the processing of field survey data into the images they view.
The objective of this course is to provide an insight into the decision-making processes with regards to the synthesis, testing and production processing of a seismic survey. The course is intended to provide the participant with sufficient exposure to the practical and financial aspects of data processing to permit confident project supervision.
WHAT YOU WILL LEARN
Upon completion, participants should have a better understanding of the data processing operation and its pitfalls. They should be able to plan a processing sequence, improve contract negotiations with regards to parameter testing and critically oversee the processing operation during visits to a processing centre.
OUTLINE
This is a combined lecture and workshop course. It includes elements of project planning, parameter testing and quality control.
Revision of basic principles
Definition of processing objectives
Geological considerations of processing sequence
Budgetary and contractual considerations
Processing centres, computer power and data transmission
Receipt of field data and pre-processing handling
Data formats, sample recovery and demultiplex
Quality assessment and noise analysis
Navigation and surveying base map construction
Editing and amplitude compensation
Wave-shaping processes – deconvolution
Frequency domain analysis and operations
Common depth point geometry and data sorting
Geometrical considerations of normal move out
Velocity analysis methods
Weathering layer calculations and static corrections
Data enhancement processes – filtering and scaling
Identification and treatment of multiples
Dip move out and the migration process
Output formats and media storage
Processing reports
WHO SHOULD ATTEND
The course is aimed at geologists and geophysicists who are primarily officebased and mainly involved in interpretation and management duties. A basic knowledge of seismic principles and data processing techniques is assumed.
