The reflection seismic methods in the search for oil and gas for non-geophysicists
In modern exploration for oil and gas, 3D seismic is a key to a successful program, especially in marine and frontier areas. The reflection seismic method is the proven necessary technology in order to map and delineate targets to reduce the exploration drilling risks. 3D seismic also plays a significant role in reservoir characterization, development and monitoring hereafter.
This course is an introduction to the applications of basic seismic reflection method fundamentals in a non-technical and yet practical form in search for hydrocarbons. The course will cover data acquisition (collection), processing and interpretation. The audience will learn the limits of seismic method in terms of resolution, detection and imaging.
In general the course is focused on understanding how seismic data is acquired and utilized in the petroleum exploration business
