The May edition of Oilfield Technology is freely and widely distributed at the EAGE conference. CGG paid to appear on the cover and also got to contribute an article on a topic of our choice. This was designed to reflect our current advertising and ...
There are a number of geophysical challenges when attempting to image the sub-surface in the Central North Sea. These consist of shallow anomalies, heavy multiple contamination and sharp velocity contrasts. With a combination of broadband data and CGG’s latest processing and imaging techniques, these ...
The main area of hydrocarbon exploration in the Northern North Sea has been within pre- and syn-rift Jurassic sandstones. This is with the exception of chalk reservoirs in the Ekofisk field and Palaeogene sand reservoirs of the Frigg field. Now, with ignited interest in ...
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 ...
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 ...
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 ...
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 ...
The Banda Arc is of great interest to petroleum explorers because of abundant onshore and offshore oil and gas seeps and similarities with geologically contiguous Mesozoic and Cenozoic successions in Australia where numerous petroleum systems exist and have been exploited (the Mesozoic basins are ...
