Glossary Broadband Benefits for interpreters
Broadband data: Seismic data with an extended band of usable frequencies. GeoStreamer data is recorded from as low as 2.5 Hz up to 200 Hz. (Read more about GeoStreamer)
Compartmentalization: The geological segmentation of once continuous reservoirs into isolated compartments
Cycle skip: When a mistie exceeds a full wavelet
Lead: A feature that provides a trapping geometry for hydrocarbons, identified within a play fairway (or otherwise). This is an opportunity that has not been fully evaluated, nor derisked technically or economically.
Mistie: A situation in the interpretation of seismic data in which predicted and actual values differ, or when an interpreted reflection does not close, or tie, when interpreting intersecting lines; or when interpreted seismic data do not match results of drilling a well.
Seismic facies: Mappable, 3D seismic units composed of groups of reflections whose parameters differ from those of adjacent facies units
Sidelobes: The non-geological related events on either the side of a wavelet
Qualitative interpretation: Mapping the subsurface by marking laterally continuous reflectors and discontinuous events such as faults and stratigraphic pinch-outs
Quantitative interpretation: The application and integration of rock physics to predict reservoir parameters, such as lithology and pore fluids, from seismically derived attributes (Read more about reservoir characterization)
