... Abstract Commencing in 2018, ADNOC undertook a mega seismic campaign ( Cambois et al., 2019 ), acquiring approximately 30,000km 2 of ocean bottom sensor (OBS) data in the challenging imaging environment of offshore Abu Dhabi. The region posed difficulties due to ultra-shallow water depths...

... Abstract The subsurface of offshore Abu Dhabi is characterized by shallow waters followed by a complex near-surface and shallow salt diapirs with associated faulting. We focus on the objective of imaging the near-surface above a salt structure in order to reduce drilling hazards and to assess...

... Abstract The ultra-shallow water-depth and hard water bottom of offshore Abu Dhabi are responsible for generating a complex multiple wavefield . Removing this energy is critical for accurate imaging of the subsurface. Almheiri et al. (2022) , demonstrated the effectiveness of up/down...

... 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...

... by the hardness of the seafloor and anomalies in the overburden. These challenges are currently being addressed through diffraction imaging. In 2022, Diffraction imaging is performed for 10×10 KM 2 pilot area, due to which we were able to delineate karstic feature in detail and faults at reservoir...

... quantum computation computing propagation quantum annealer computational advantage imaging Introduction Seismic data processing depends entirely on the data collected from the field. Initially terabytes of seismic data is collected from the field. After the seismic data acquisition...

... 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...

... interface is key to the imaging of salt flank. Reflection coverage of salt flank is highly subjective. Since detailed salt geometry around the well is unknown, the estimated coverage is mostly speculative. 3DVSP modelling was updated after drilling the well with actual trajectory and well velocities...

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...

This study is focused on a 3D land seismic survey recently acquired that is currently at the time and depth imaging stage. The early-out volumes...

... Abstract Low fold poorly sampled vintage seismic data often suffers from poor fault imaging. This can have a critical impact on reserve estimation and well planning. Acquiring high density seismic data over producing fields requires overcoming logistic challenges along with additional costs...

The same pass of radon demultiple was also tested after the Extended Interbed Multiple Prediction, since the two algorithms target different types of multiples.
