Apex Spectral is a unique technology company based around a small team of specialized scientists. Founded in 2002 Apex Spectral was the first to discover that dispersion is manifest in seismic data and can be used to explore for oil and gas. Fluid movement in the reservoir pore throats when excited by a seismic wave causes P-wave dispersion, and Apex images this dispersion with signal processing technology called ADF®. Apex’s frequency domain ADF® DHI technology is broadly patented, and the company enjoys a growing worldwide customer base.
