A Rayleigh surface wave tomography with optimal coverage approach based on the creation of virtual raypaths by interferometry is proposed. The array based conventional surface wave picking methods often provides inhomogeneous or sparse coverage for high-resolution tomography. The delivered inversion result can suffer from ...

We introduce a method for separating residual statics and NMO velocities by maximising sparsity in tau-v and tau-p domains. Surface Consistent statics are computed without a-priori knowledge about velocities needed for NMO corrections. In such way static time shifts will not be applied to ...

All seismic data, whether 2D, 3D, post-stack or pre-stack contains noise. Typically, this noise is comprised of both coherent and random components. Coherent noise presents itself as regular patterns in the seismic data. It may appear to be random or coherent depending on the ...

The Gippsland Basin in South-Eastern Australia has been producing hydrocarbons since the early 1960’s when several giant oil and gas fields were discovered. It can therefore be considered to be a mature area, where production rates have been declining for the last twenty years ...

Barreirinhas basin is located in the north-east of Brazil and is part of the Brazilian equatorial margin, a new exploration frontier with complex geology. This basin is characterized by a rugose water bottom, a fast carbonate platform, shallow gas pockets and a complex channel ...

Paper written in association with SNH for the March 2018 additions of First Break. Paper focusses on understanding why well success was low for the offshore Douala basin and how the interpretation of the results of the GeoSpec Regrid will enable a better understanding ...

The scope for using EO satellites for routine monitoring of offshore operations is continually expanding in ways that make factors of cost and time more feasible than ever before. Near-real-time processing and delivery remain the most appropriate solution for emergency scenarios; however, proactive monitoring ...

This case study of an advanced quantitative interpretation workflow is tailored for a seismic multiclient program in the Wolfberry Play of the Midland Basin. Seismic imaging begins by providing a structural interpretation basis, then quantitative interpretation provides 3D elastic and geomechanical attributes through prestack ...

The Gippsland Basin in South-Eastern Australia is located approximately 200 km east of the city of Melbourne, and remains one of Australia's most prolific oil and gaThe major fields were discovered in the early 1960’s, using images from a coarse 20-km (12 mile) grid ...
