This paper reviews elastic property changes in anisotropic mediums and proposes a workflow to model elastic stiffness tensor using conventional well logs in a vertical transverse isotropic medium. The proposed workflow uses the concept of downscaling and then upscaling of normal logs using Backus ...

The aim of this study is to discuss the challenges for interbed multiple attenuation in the Asia-Pacific region. Many possible multiple generators such as seafloor, carbonate layer or volcanic flow are found in the data. Without any prior subsurface knowledge, the ISS method is ...

The search for hydrocarbons has spanned vast areas of the globe. Despite many successes, entire basins and plays have been deemed unprospective, perhaps prematurely, based on single well results, or poor-quality seismic data. The advent of broadband seismic acquisition, combined with new deghosting/imaging algorithms ...

The Northern Viking Graben seismic dataset was acquired using CGG’s BroadSeis™/BroadSource™ true broadband solution, which combines a multi-level source and curved variable-depth streamer technology with advanced and customized imaging technologies. The dataset covers more than 35,000 km2, spanning both the Norwegian and UK North ...

DENVER–The economics of unconventional plays can be improved by placing horizontal wellbores to target facies with the most favorable reservoir and geomechanical properties. Recognizing that, an integrated multidisciplinary approach was developed to reduce economic risk, facilitate improved and faster decision making, and enable more ...

Parameterization lies at the center of anisotropic full-waveform inversion (FWI) with multiparameter updates. This is because FWI aims to update the long and short wavelengths of the perturbations. Recently, there has been an intensive effort to determine the optimal parameterization, centering the fundamental discussion ...

Initial imaging results are deeper and clearer than have been seen in this area before, with enhanced imaging of the Triassic to Lower Cretaceous reservoir units. In addition to demonstrating that there is at least 20km of sediment in this area, clear faulting and ...

We demonstrate how we unlocked the potential of one of the last underexplored regions of the South Atlantic margin through smart seismic acquisition, processing technology and close collaboration.

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 ...
