This case study demonstrates the collaborative advantages when an Operator and a Geoscience Contractor work collectively as part of a tailor-made Integrated Virtual Asset team, to solve complex subsurface challenges in a restricted time frame. The operating challenge was to de-risk a potential drilling ...

Mohns Ridge is currently the subject of much interest owing to the occurrence of hydrothermal vent fields and critical metal-bearing seafloor massive sulphide (SMS) deposits along this segment of the ultraslow-spreading Arctic Mid-Ocean Ridge. To target where potentially mineable SMS deposits may form or ...

Acoustic full-waveform inversion (FWI) is widely employed to produce high-resolution subsurface models, especially for the P-wave velocity. However, more complex geological challenges, such as shallow chalk and salt, generate strong impedance contrasts that exhibit elastic effects, causing acoustic approximations to struggle. In parts of ...

A good estimation of velocity anisotropy is important in a pre-stack depth migration project in order to obtain proper focusing and accurate depthing of the seismic image. Considering that the velocity along the bedding is expected to be faster than across the bedding, the ...

Multiple contamination in seismic data from the south of the Sultanate of Oman is challenging due to the combined presence of short-period surface and internal multiples generated in the upper section. We present an innovative workflow to attenuate multiples in the pre-migration pre-stack domain ...

The shallow water region of the Gulf of Mexico is known to present significant petroleum prospects due to dynamic tectonic activities during the late Cretaceous to early Tertiary. Previous imaging in this region using sparse ocean bottom cable (OBC) surveys was poor, mainly due ...

Land FWI has been applied to seismic data in the Sultanate of Oman in the past years, but its usage has been limited to low frequency updates and input for migration purpose only. With proper input data conditioning, initial model preparation and velocity inversion ...
