SINBAD Consortium Meeting - Fall 2011

Executive Summary DNOISE:

Dynamic nonlinear optimization for imaging in seismic exploration (DNOISE) is a multidisciplinary research project involving faculty members from the Mathematics, Computer Science, and Earth and Ocean Sciences departments at the University of British Columbia. DNOISE aims at one of the most pressing questions in the oil and gas industry namely ---"How to image more deeply and with more detail?" This pressing question needs to be answered if our energy-intensive society is to adequately address the current surge in demand for hydro-carbon resources.

DNOISE operates at the intersection of information, optimization and seismic theory, and aims to provide answers to the basic questions "What accuracy is attainable given a certain seismic acquisition?", and "How can we improve the acquisition to obtain a certain accuracy?" To answer these questions, DNOISE will leverage recent results from information theory, known as uniform uncertainty principles. These recently discovered principles constitute a new paradigm since they provide explicit conditions under which (seismic) data can be recovered from incomplete and noisy measurements. As part of DNOISE, we plan to leverage these results towards a large suite of outstanding problems in seismic imaging that range from the canonical deconvolution problem to the removal of coherent signal components and amplitude recovery.

DNOISE derives its potential from the development of signal representations that are sparse and optimization techniques that promote this sparseness. This combination is exploited in DNOISE's formulation of the seismic imaging problem, leading to an improved image quality, including explicit estimates for the image accuracy, i.e., the error.
