Viridien wins Oman seismic imaging contract

Viridien has been awarded a three-year contract by Petroleum Development Oman (PDO) to provide advanced land seismic imaging services at its dedicated processing center (DPC) in Muscat, Oman

PDO is the foremost oil and gas exploration and production company in Oman, producing the majority of the country’s crude oil production and gas supply, with a concession spread over more than 75,000 sq km. This makes the DPC a critical proving ground for deploying new technology and workflows that can meet the imaging requirements of PDO’s exploration and production activities.

Advanced algorithms

The new contract will see Viridien’s geophysical experts at the Muscat center, its largest DPC worldwide, working to deploy advanced proprietary algorithms to improve the image quality of PDO’s growing library of seismic data. Oman land data is characterised by complex near-surface conditions and strong multiples. High-resolution velocity model building, and elastic full-waveform inversion will be key to overcoming these challenges and to enhancing subsurface understanding. (Full-waveform inversion (FWI) accurately computes highly detailed, data-driven models of subsurface velocity, absorption (Q) and reflectivity, for use in seismic imaging and interpretation, by minimising the difference between observed and modelled seismic waveforms.) Viridien will also address new challenges, such as increased data density, developing land 4D monitoring and reinforcing synergies between seismic imaging and reservoir characterisation. To support these capabilities, Viridien HPC & Cloud Solutions specialists will deliver the in-house High-Performance Computing (HPC) capacity required to implement the most advanced workflows.

Sophie Zurquiyah, CEO, Viridien, said, "Congratulations to our Muscat DPC team whose technical excellence and outstanding service have led to this new contract award. We will build on this success, by continuing to advance our geoscience and HPC technologies to address PDO’s unique E&P challenges and support their business objectives.”

The new contract continues a longstanding collaboration between Viridien and PDO and follows a previous three-year contract extension from PDO to continue providing advanced land seismic imaging services at its DPC in Muscat. During the time of this contract, Viridien addressed challenges such as adapting to PDO’s transition from cable to node multi-source acquisition, incorporating machine learning into the workflows for both efficiency and improved quality, and supporting PDO in their ongoing challenge to increase the applicability of seismic in reservoir characterisation.
