... migration, which is unfavourable to fracture imaging. Kirchhoff migration is a single ray imaging method, and the signal-to-noise ratio around imaging points is usually not high enough. Kirchhoff migration gathers cannot provide multi-dimensional information and subsequent processing for reflection...

... Carbonate reservoir seismic imaging mostly present a challenge due to narrow impedance contrast, especially when dealing with subtle structures. However the last decade has seen significant acquisition and processing innovations. Most of the remaining exploration potential for conventional plays...

... With high fidelity seismic data and accurate velocity model as the cornerstone, the DI technique then plays its crucial role for revealing the small-scaled geological features. As the last but not least key step, the diffraction imaging technique actually includes two parts: diffraction imaging...

... Abstract Seismic surveys are generally designed to image deep reservoirs, which leaves the near-surface woefully under-sampled. This is particularly a challenge offshore Abu Dhabi, where a complex near-surface – with karstic collapses and meandering channels – contaminates the seismic image...

... measurements. This model, therefore, had a large uncertainty as to the salt location and geometry. Concerns of potential drilling hazards associated with salt required utilizing the ability of borehole seismic to look-ahead of bit to image salt and direct the well such that it would be sufficiently far away...

Whilst the reprocessing project achieved the project objectives and generated good subsurface images, it did not run as smoothly as hoped, despite being processed by one of the premier multinational processing companies. The extremely large sand dunes, which...

... of the reflector were determined. The reflections recorded matched very well with the structure recorded from a walk-above VSP and the resistivity image also acquired in the same well and with the 3D seismic. In another field offshore Abu Dhabi, standard dipole data was used to image layering and natural...

The main reason behind these failures can be found in the complex subsurface geology that characterize this region, especially when compared with neighboring...

... Abstract Carbonate reservoir rocks of the Najmah formation in Kuwait, with low porosity and low permeability, have been characterized using integrated digital and physical rock analyses methods. High-resolution imaging and analyses determined the microstructural characters of mineral matrix...

..., the extrapolation method is implemented by finite-difference modelling ( Gray et al., n.d. ). The wave extrapolation in time can be reduced to analyse numerical approximations to the mixed-domain space-wavenumber operator.
