Turning Dust into Data: A Technical and Operational Look at Soiling Losses in Solar Operations

TGS — Fri, 05 Dec 2025 18:08:57 GMT

In solar power plants, even a thin layer of dust, sand, or salt can make a big difference.

Soiling, the gradual accumulation of dirt on PV modules, is one of the most common and costly sources of performance loss. Yet it's also one of the hardest to measure accurately.

For operators managing large or geographically dispersed portfolios, the challenge is clear: installing soiling stations everywhere is rarely practical. Decisions about when to clean, how to estimate losses, or where to prioritize resources often rely on assumptions or siloed data.

The result? Uncertainty, unnecessary costs, and missed production.

TGS Prediktor's Soiling Analysis feature in PowerView changes that, by turning "dust" into reliable, actionable data.

TGS Expands Multi-Client Coverage in the Malay Basin With Peninsular Malaysia 3D Mega Merge Stage 4 Reprocessing Project

TGS — Tue, 18 Nov 2025 05:59:59 GMT

OSLO, Norway (18 November 2025) – TGS, a global leader in energy data and intelligence, announces the expansion of its multi-client seismic coverage in the Malay Basin with the Peninsular Malaysia 3D Mega Merge Stage 4 Reprocessing project.

TGS is reprocessing legacy 3D datasets to improve subsurface clarity and provide a consistent, basin-wide view of the Malay Basin. The use of uniform technology and workflows across all stages helps operators gain faster exploration insights.

Stage 4 extends the regional dataset by reprocessing and merging approximately 16,000 square kilometers of legacy 3D seismic data covering key exploration blocks relevant to upcoming Malaysia Bid Round (MBR) opportunities. MBR is an annual licensing round hosted by Malaysia Petroleum Management and PETRONAS , offering a range of opportunities, from exploration blocks and discovered resources to mature assets and technical studies, allowing investors to grow their energy portfolios.

TGS, Axxis Multi-Client As And Viridien Complete Omega Merge - The Largest Continuous Obn Dataset Over The Norwegian North Sea

TGS — Tue, 15 Jul 2025 14:19:17 GMT

OSLO, Norway (15 July 2025) TGS, a global leader in energy data and intelligence, in collaboration with Axxis Multi-client AS and Viridien, have announced their successful completion of the final imaging of OMEGA Merge, to deliver a single, seamless and unified high-quality dataset across the Heimdal Terrace, Utsira, and Sleipner Ocean Bottom Node (OBN) multi-client surveys.

Spanning a total area of 3,700 square kilometers from the deployment of over 250,000 nodes and 9.5 million shots, OMEGA Merge is the largest continuous OBN dataset on the Norwegian Continental Shelf.

To ensure the highest-quality data imaging across the boundaries of the Utsira, Sleipner, and Heimdal OBN surveys, the data underwent pre-migration matching to ensure consistency in time, phase, amplitude, and frequency content. The velocity model was then unified using Viridien’s advanced time-lag full-waveform inversion (TL-FWI) and long-wavelength tomography technology. Utilizing this unified model, the data was pre-stack depth-migrated, to produce a seamless and continuous volume that covers the entire OMEGA Merge area.

David Hajovsky, Executive Vice President of Multi-Client commented, “The completion of OMEGA Merge marks a significant step forward in subsurface understanding of this complex region. By unifying these OBN surveys, we are delivering a seamless, high-resolution dataset. With this, our customers gain significantly improved resolution and structural continuity to de-risk subsurface interpretation and accelerate prospect evaluation.”

The final dataset brings substantial improvements in resolution and structural clarity, revealing previously unseen exploration targets and providing greater confidence in prospect understanding compared to vintage seismic data. The dataset is now available for licensing.
