Seismic for unconventionals: Can seishnic technology improve success rates in the E&P of oil and gas from shale and tight sand?

摘要

Seismic surveying objectives used to be focused primarily on providing images of the subsurface to identify likely structural traps for drilling. In unconventional plays, while structure remains important, factors such as stratigraphy and stress also control the success of drilling and completions campaigns. Continuous advances in acquisition and processing technology have led to ever-improving quality and reliability of seismic data, and these data now can be trusted to provide an increasing range of valuable information about lithology and other important reservoir conditions.
