The Early Cretaceous sands on the Måløy slope constitute as reservoir for many oil and gas discoveries as seen in the Duva field and Hamlet and Ofelia discoveries. These sands have been deposited in submarine channels and fans, fed by material derived from the ...

Recent exploration activities within Paleocene and Eocene remobilized sands have proven the injectite play in the Northern Viking Graben (NVG). Wells targeting these sands have led to new discoveries such as Kveikje (2022) and Heisenberg (2023). This study proposes a robust methodology for detailed ...

We present a means to estimate porosity and permeability at cm-scale resolution using whole-core computed tomography (CT) scans. We focus on carbonate reservoir intervals of the Buah Formation and Khufai Formation, both part of the Precambrian Nafun Group, from two wells located onshore Oman ...

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 ...

We present the use of elastic full waveform inversion (FWI) of surface waves to create a detailed shear velocity model of the near surface in the Middle East, where the shallow geology features strong velocity contrasts, making traditional velocity model building techniques challenging. The ...

Full-waveform inversion (FWI) uses the full wavefield as input but, in general, diving waves are the key driver of the method. How to maximize the contribution of reflected waves is an important factor for success of FWI, especially on seismic data with a short ...

Elastic full-waveform inversion (FWI) is now emerging as an industrial tool for the compressional velocity (Vp) model build, driven mainly by diving and reflected P waves. On the other hand, the inversion of S waves in elastic FWI to update shear velocity (Vs) models ...
