Viridien, through its subsidiary specialising in geophysical imaging, has been awarded a seismic reprocessing contract by the Hassi Bir Rekaiz Group. This consortium, comprising Algerian state-owned company Sonatrach and Thailand’s PTT Exploration and Production (PTTEP), has tasked Viridien with reimaging two three-dimensional seismic volumes covering a total area of 2,400 km² in the Hassi Bir Rekaiz concession, located in the Berkine Basin in eastern Algeria.
The original data, acquired in 2011 and 2013 respectively, will undergo a full integrated reprocessing, leveraging Viridien’s advanced modelling tools to enhance imaging quality and geological accuracy. The 13-month project aims to optimise quantitative interpretation by improving the reliability of amplitude, phase, and frequency attributes.
Technology supporting seismic interpretation
To meet the client’s imaging objectives, Viridien is deploying its latest seismic velocity modelling technologies. The goal is to deliver more detailed subsurface imaging, enhancing understanding of reservoir structures, including faults, which are often critical in evaluating hydrocarbon potential. Data fusion is intended to maximise the value of existing datasets, reducing the need for further acquisition while optimising the use of available resources.
The French subsidiary has recently expanded its capabilities in North Africa, increasing its contract portfolio across the region. The Hassi Bir Rekaiz project is part of this targeted growth strategy.
Strengthening Viridien’s footprint in North Africa
Peter Whiting, Executive Vice President, Geoscience at Viridien, stated that the contract demonstrated ongoing client confidence in the company’s service offering. “We are pleased to have been selected for another contract in Algeria, showing the trust our clients place in our experience and differentiation in this growing market,” he said.
The economic value of such projects lies in their ability to reduce uncertainty in drilling planning, supported by deeper geological insight. Viridien continues to enhance its seismic data processing techniques to extract more actionable information from existing records, as per the demands of regional operators.
