Bergen, 26 August 2025 – Shearwater Geoservices AS (“Shearwater”) announces the award of a deepwater Ocean Bottom Node (OBN) seismic survey offshore Angola by ExxonMobil’s affiliate Esso Exploration Angola Block 15 Limited. The two-month project is scheduled to commence during Q3’25. The project will be delivered using Shearwater’s proven OBN platform, featuring the SW Tasman […]

SUMMARY We investigate options to perform integration preconditioning for Ocean bottom node (OBN) data acquired with accelerometers. When amplitude perturbations due to sensor saturation are present, integration exaggerates them through convolution with the integration filter; therefore, their correction is desirable. Furthermore, the affected samples may impact PZ calibration, wavefield separation and multi-dimensional deconvolution, therefore a […]

SUMMARY We present a novel constrained Dix inversion method that leverages proximal operators within the Alternating Direction Method of Multipliers (ADMM) framework. Addressing problems inherent to Dix inversion, our method robustly manages various noise types in picked RMS velocity functions, including spikes and outliers in measurements that can be distributed in both the space and […]

SUMMARY Seismic depth-imaging and inversion in complex geology often use wave-equation operators for TTI or TORT symmetries, but these still struggle with numerical instabilities due to incorrect adjoint operators and rapid tilt variations of symmetry axes of elastic tensors. We propose a novel approach using frame bundles to describe heterogeneous anisotropic velocity models, aligning local […]

We’re announcing a significant milestone in our multi-year collaboration with NVIDIA, delivering breakthrough progress in applying Generative AI (GenAI) to Uncertainty Quantification (UQ) for seismic processing and imaging. This paves the way for our processing software Reveal where users can access advanced NVIDIA-accelerated tools for quantifying seismic-related uncertainty and strengthening risk assessment in exploration, production […]

Shearwater is making fast strides in Brazil’s Foz do Amazonas Basin, sharpening regional understanding through a focused subsurface collaboration with Eliis. Building on our recently completed, industry-backed reprocessing project—delivering over 7,000 sqkm of high-quality reprocessed data—this next phase brings in cutting-edge interpretation workflows using Eliis’ PaleoScan™ software, providing a highly detailed and connected view of […]

Africa is one of the most exciting regions for offshore exploration. At Shearwater, we’re proud to be playing a key role in that story—with a growing track record of pioneering surveys and high-impact data delivery across the continent. From Namibia’s Orange Basin to the deep waters of Ghana and Angola, we’ve shown what our technology […]

Abstract The Pelotas Basin in Southeast Brazil is rapidly emerging as one of the world’s most promising regions for hydrocarbon exploration. This paper examines the impact of the recent exploration successes in its geological conjugate, the Namibian Orange Basin, where multibillion-barrel discoveries have been made over the past four years. The success in the Orange […]

With reference to the first quarter report on 28 May 2025. Bergen, 02 July 2025 – Shearwater Geoservices AS (“Shearwater”) has implemented measures to increase balance sheet resilience in response to the combination of short-term low activity levels and working-capital intensive projects during the second and into the third quarter of 2025, as mentioned in […]
