The first block for exploration in the formerly disputed zone between Norway and Russia (PL589) was awarded in 2016 and is located 250 kilometres from the earest exploration well. The main objectives...

This paper presents a new method for simultaneous source deblending developed in the context of compressive sensing. The deblending solution is formulated as an inverse problem which is solved in...

A major impediment to the full understanding of the data acquired in marine seismic is the restricting assumption of a flat and stationary sea surface used in certain pre-processing tools. A first...

Deghosting a hydrophone-only measurement requires accurate description of seismic wavefield scattering at the sea surface. In recent years, attempts have been made to deghost hydrophone-only data...

The PGS model uncertainty analysis tool helps mitigate the risk associated with target positioning and volumetrics. The workflow quantifies the uncertainty inherent in a final velocity model and the...

Andrew Long considers present and future opportunities using separated wavefield data to illuminate, resolve, characterize and monitor reservoir properties and production in various marine settings.

We present a new model building workflow for simultaneous building of high resolution Q and anisotropic velocity models. The tomography algorithm uses both travel times and spectral ratios from...

The Ceduna Sub-basin in Australias southern margin offers an untapped opportunity for significant petroleum resource as part of the global exploration portfolio. Analogous to the prolific Niger delta...
