Chevron deploys ViaLogy’s ‘novel’ seismic processing package

QuantumRD ‘probe’ adds noise to seismic data for carbonate porosity mapping.

UK-based Vialogy reports successful demonstration of its ‘QuantumRD’ seismic processing technology on a dataset provided by Chevron. Quantum RD ‘probes’ a seismic data set by adding synthetic noise to the data to detect attributes of interest, such as porosity. A test last year involved 3D seismic data in the lower Permian Basin where QuantumRD was applied to 50 sq. km. of Devonian, Wolfcamp, Strawn and Atoka formations between 8,000 and 13,000 feet.

Vialogy’s core ‘quantum resonance interferometry’ technology is claimed to ‘detect weak signals buried in background noise,’ and can be applied to seismic, electromagnetic and magneto telluric data. This is achieved by exploiting ‘normally disregarded’ noise variations induced by changes in porosity, fluid presence and permeability. Vialogy claims that its patent active signal processing technology that adds a synthetic noise source to data is ‘unlike conventional signal processing*.’ More from Vialogy.

*Actually ‘conventional’ deconvolution frequently involves adding noise to data.
