Objective
Development of a new improved and less costly method for the study of reservoirs.
Two field campaigns have been carried out. Data obtained on the Faulquemont and Saint Just sites have been processed with the traditional surface seismic methods.
Acquisition, conventional processing and interpretation of OSPs recorded on different mineworking and oil sites. Acquisition provided the data base indispensable for continuation of the project and have improved definition of the limits and optimum conditions of application of this method. Conventional batch processing proved to be poorly adapted to this new configuration. leading to the second phase of the project.
Study and design of a new software using interactive graphics and set-up on a minicomputer. This software, known as GIPSO (graphical interactive processing software for offset VSP) which will in the end replace conventional processing is now being tested. Its modularity and numerous graphic outputs on screen provide time savings whilst ensuring better quality than anything currently available.
The method which is studied makes use of: drilled wells in which seismographs are installed, and a variable surface source. The project was carried out in 3 phases :
1. Data acquisition
2. Processing
3. Interpretation
