Recently there has been renewed interest in the hydrocarbon potential of the Perth Basin in Western Australia. Recent discoveries of gas have shown that there is a working hydrocarbon system within at least the northern and central parts of the basin. In most parts ...

The deepwater Gabon South Salt basin represents one of the last underexplored regions of the West African continental margin. A new 25,000-sq km (9,653-sq mi) broadband 3D seismic survey was recently acquired in the basin as part of an integrated eoscience program to support ...

Gulf of Mexico (GOM) subsalt imaging often suffers from poor illumination due to salt-related wavefield distortion, even with full-azimuth (FAZ) acquisition. In order to image the weakly illuminated subsalt plays, isolating the signal from the noise is a crucial component of many depth imaging ...

This case study highlights how the application of an optimized hydraulic fracture stimulation plan, by honoring lateral well geological heterogeneities measured by RoqSCAN, improved completion efficiency and well production within the Cleveland Sandstone formation, Oklahoma, USA.

The quality of the seismic data you record depends on the quality of the energy generated by the source, how it interacts with the subsurface and the ability to record all the effects of those interactions. To obtain the required response from the reservoir ...

In this article, we focus on variable-depth streamer acquisition and propose a full broadband processing solution that involves three important components: (a) 3D deghosting; (b) Q estimation using Q-Tomography; (c) Q application via Q pre-stack depth migration (Q-PSDM).

In seismic processing and reservoir characterization we often need to measure relative displacements between different realizations of data. Over the years many methods have been developed utilizing different similarity measuring techniques. Such alignment or warping methods are often effective signal or image processing tools ...

In this study on the Mowry and Muddy interval in the Powder River Basin, we have evaluated a number of the controlling factors on productivity and identified those regions with greater prospectivity across the basin. We have combined classic geological disciplines with robust geophysical ...

In this paper we discuss a workflow to update low frequency models in time-lapse inversion studies. In this workflow we invert the base seismic survey and the difference between base and monitor survey in two separate inversion runs. The production effects are picked on ...
