Historically, Brazilian pre-salt fields have been imaged by narrow-azimuth towed-streamer (NATS) data. More recently, ocean bottom node (OBN) acquisitions have been employed to image and monitor already producing fields. In cases as such, 4D seismic monitoring is only possible via NATS/OBN hybrid pairs, where ...

Chris Page, EVP New Businesses Development, Viridien, explains how technologies used to support oil and gas exploration and development are enabling innovations in the energy transition and beyond.

We demonstrate how the use of multiples in imaging may provide improved shallow illumination and potentially reduce the requirement for extensive site-survey acquisition in some areas.

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 ...

Marine vibrator sources offer the ability to emit a fully customisable and accurately repeatable sweep signature. Resulting peak amplitude levels are much lower than for airguns, making marine vibrators potentially preferable for the welfare of marine life. While the highly repeatable nature of the ...

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 ...

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 ...

A multi-disciplinary project is presented utilizing data from the CGG archives and re-purposing them for porphyry copper deposit exploration. we reprocess the data, interpret and combine the results and place them within a holistic mineral systems framework to derive new exploration insights and demonstrate ...

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 ...
