Gaussian Beam depth migration (GBM) overcomes the single-wavefront limitation of the most implementations of Kirchhoff migration, and constitutes a cost-effective alternative to full-wavefield imaging methods such as reverse time migration. Common-offset beam migration was originally derived to exploit symmetries available in marine towed-streamer acquisition ...

Variable-depth streamer acquisition has become a popular solution for marine seismic acquisition to obtain data with both low and high frequencies: the curved cable profile produces notch diversity that minimizes the residual ghosts in stacking and the deep towing nature provides high S/N at ...

We present a case study over the South Utsira High. This survey was the first commercial BroadSource with BroadSeis 3D survey, and was acquired over the Johan Sverdrup field. A small pilot survey was initially acquired over the Avaldsnes discovery and later extended to ...

We present the results from flying the FALCON-2 system over the R.J. Smith AGG test range at Kauring, West Australia.

We describe opportunities and challenges for imaging seismic data acquired using conventional marine sources and receivers located on the seafloor. Opportunities include the promise of greater imaging resolution than sea-surface acquisition and processing can offer, especially using P-wave to S-wave converted reflection energy (PS ...

A gas field, China, the target reservoirs are mainly delta front depositions, which are tight, thin, and below the tuning thickness. In order to charaterize the thin effective reservoir and porosity distribution in this field, a geostatistical inversion and co-simulation were performed. Using geostatistical ...

In this paper, we described some of the key challenges faced and their solutions during the reservoir characterization study. Shear log prediction can be done quickly by methods, such as multi linear regression and also by building a robust petro-elastic model, if pore geometry ...

Seismic Reservoir Characterization is a well-known technique to obtain a better understanding of hydrocarbon-bearing reservoirs by careful analysis and integration of petrophysical and seismic data. The petrophysical properties are normally obtained through the evaluation of well logs and core data. A rock physics model ...

In this paper, we present a UK case study and draw on lessons learnt from the American market by using mineralogical and textural data obtained by AM and measured TOC to constrain and improve the accuracy of petrophysical modelling. We characterize a UK unconventional ...
