Frozen Methane Under the Seabed is Thawing – And It's Worse Than We Thought
methane migrated laterally, upwards and landwards toward Africa and leaked in much shallower water. Beneath a layer of up to 80 metres of sediment are 23 giant craters on the ancient seabed, each one kilometre wide and up to 50 metres deep, big enough to be filled with multiple Wembley stadiums.The seismic imaging provides the tell tale signs of methane immediately below the craters. And similar craters elsewhere form due to prolonged or explosive release of gas at the seabed.These craters are not located in the vulnerable zone where all the attention has been – they are landward of it at about
Shell to Use New AI Technology in Deepwater Oil Exploration
of innovation and performance, said in a statement. The goal is to improve operational efficiency and speed, and increase production and success in exploration. The new process can shorten explorations to less than nine days from nine months, the companies said. "Generative AI for seismic imaging can positively disrupt the exploration process and has broad and far-reaching implications," said Bruce Porter, chief science officer for Austin, Texas-based SparkCognition. The technology would generate subsurface images using fewer seismic data scans than usual, helping with deep
CGG, TGS Win OBN Seismic Survey Work Offshore Norway
, including time-lag full-waveform inversion, to create a high-quality 3D volume that will enhance resolution and structural definition of the complex geology and reservoirs in the region. Sophie Zurquiyah, CGG CEO, said: “CGG has an unrivalled track record of successfully conducting OBN seismic imaging projects around the world and in the North Sea in particular. Our geoscientists will apply this regional insight and our very latest OBN technologies and expertise to deliver the highest-quality OBN images to meet industry needs for the continued exploration and development of the NCS.&rdquo
Petrobras Extends Deal for Use of CGG's Seismic Processing Software
as a key supplier. This latest expansion of our Geovation licensing agreement reflects the strength of this relationship and the significant advantage that our state-of-the-art subsurface imaging technology provides. "As the powerhouse behind the success of CGG’s own high-end seismic imaging services, it is the most efficient and reliable software platform for geophysicists working with ever-growing data sets and facing increasingly complex imaging challenges, such as pre-salt illumination.”CGG said that the new agreement included expert training from CGG’s GeoTraining
Shearwater GeoServices, ConocoPhillips 'Reveal' Tech Collab
Offshore seismic surveyor Shearwater GeoServices has signed a technology sale and transfer deal with the oil firm ConocoPhillips, involving seismic imaging technology that will be implemented in Shearwater's Reveal software.According to Shearwater, Reveal provides time and depth processing and imaging for both land and marine environments from within a single user interface. Shearwater uses Reveal internally for all processing projects. The software is licensed to oil and gas companies, contractors, consultants and is used by academia for both teaching and research."With this partnership

low-carbon tech company Horisont Energi to jointly work on the identification and classification of CO2 storage reservoirs and develop new Carbon Capture and Storage (CCS) technologies.A few days later, TGS announced a collaboration with oilfield services giant Halliburton to bring advanced seismic imaging to fiber optic sensing to help oil firms boost output rates, but also explore carbon storage options, such as carbon storage monitoring, in another proof that the whole oil industry has taken note of the blowing energy transition winds.Talking about winds, TGS in August announced its involvement
Silixa Claims 'World's first' as it Installs Distributed Acoustic Sensing (DAS) System at BP's Gulf of Mexico Field
already enabled on land and platform wells will have a tremendous impact on the industry.”"The first subsea DAS VSP field recording has confirmed and shown excellent data quality with high fidelity measurements and signal-to-noise-ratio in the expected downhole array aperture for borehole seismic imaging in actively producing wellbores”, Sebastien Soulas, Senior Borehole Seismic Advisor at LYTT, said.
Sercel Launches Seabed Node for Shallow Water Seismic Acquisition
to Sercel, the compact and lightweight GPR300 features Sercel’s QuietSeis broadband digital sensor technology for ultra-quiet performance and "unmatched digital fidelity.""Its ability to record high-fidelity low-frequency signal also makes it the ideal choice for high-end seismic imaging with full-waveform inversion (FWI). In addition, its omni-tilt sensor package corrects for node inclination on the seabed, ensuring the most accurate 3C recording," Sercel said.Sercel said that GPR300 benefitted from both BGP’s know-how in seismic acquisition and Sercel’s technical
Halliburton, TechnipFMC Launch Acoustic Sensing Solution for Subsea Wells
Oilfield services giants Halliburton and TechnipFMC have jointly introduced Odassea, described as the first distributed acoustic sensing solution for subsea wells. The technology platform enables operators to execute intervention-less seismic imaging and reservoir diagnostics to reduce the total cost of ownership while improving reservoir knowledge, the companies said in a joint statement on Thursday."The Odassea service integrates hardware and digital systems to strengthen digital capabilities in subsea reservoir monitoring and production optimization," the statement reads.Halliburton
