Reservoir Seismic Characterisation

More about rock physics

Rock physics establishes a relationship between the seismic signal and the petrophysical properties in the subsurface. This connection allows us to understand and model the petrophysical and geometrical properties which give rise to the seismic signal. We then use this to “extract” information from the seismic data about the character of the reservoir in three dimensions to map extensions to existing reservoirs; locate unaccessed pay away from well control; resolve seal integrity issues; and guide optimum placement of wells in complex reservoirs. Rock physics requires a knowledge and understanding of geophysics, petrophysics, geomechanics, and the causes of the distribution of fluids in the subsurface.

Competencies in well log analysis, core measurement and analysis, elastic theory, wave propagation and energy partitioning, signal analysis and seismic processing and seismic geomorphology are all essential tools for the rock physicist. In Senergy, we combine all these tools to perform a thorough rock physics analysis to determine the petrophysical parameters that control reservoir quality, defining a strategy that allows the extraction of these parameters from seismic data.

Where grid mapping and geostatistical methods fail to describe the inter-well character of the subsurface, rock physics based seismic characterisation is the best quantitative tool we have at our disposal to reduce uncertainty and unlock the commercial potential of our assets.
