There are some additional operating concepts that could be applied here including smaller, fast support vessels and unlimited broadband VSAT solutions which may make it work well.LeeWay Odyssey transits to Bedford, Nova Scotia to test the Kraken Katfish.Who owns new value creation?In our view, there are several interesting permutations and combinations of UxVs coupled with vessels that can be applied to create a decent solution

of Geoscientists and Engineers (EAGE) conference in London on Tuesday, will enable the two companies to collaboratively provide more advanced and efficient technology for in-situ seismic and seabed monitoring.Güralp has more than 30 years’ experience in the design and manufacture of broadband seismometers and accelerometers, while Sonardyne’s experiences stretches to more than 40 years of experience in long-endurance data collection and through-water telemetry. As a consequence, clients globally will benefit from a combined offering of technology for seismic data gathering, seabed

600 kHz DVL (Doppler velocity log) and a high accuracy intelligent pressure sensor in a single unit, Sonardyne said.Oceaneering’s E-ROV has already proven the ability for battery powered remotely operated vehicles (ROVs) working in the oil and gas industry to be piloted from shore, via 4G mobile broadband transmitted from a buoy, independent of support vessels. The company’s next-generation resident hybrid ROV Freedom builds on the E-ROV concept. Due to debut in offshore trials later this year, Freedom is targeting long, maintenance free-deployments, on autonomous missions and with support

CGG Completes 2D Survey Offshore Gabon

French-based geophysical services company CGG said it has completed acquisition of 9,800 km long-offset broadband 2D multi-client seismic survey in the highly prospective Gabon South Basin.Fast-track data sets will be delivered in batches from the end of April, giving interested oil companies sufficient time to understand offshore petroleum systems and appraise blocks offered in Gabon’s 12th offshore licensing round planned for September 2019.This modern data set will help define the full extent of existing and new plays in the region. It will also aid in understanding the thickness variations

.” The E-ROV is a resident, battery-powered ROV that will go subsea with a surface buoy. It’s a work class electric vehicle with a hydraulic power pack to support its manipulator functions, and it is controlled remotely from our onshore mission support center with communications via the 4G broadband network, using a self-deployed surface buoy. We’re very proud of this achievement. Subsequent to the initial scope, we’ve been awarded a three-year contract with options from the same customer, where the E-ROV will be deployed in a variety of locations and work scopes, servicing multiple

Searcher Seismic Acquires Triok

Searcher Seismic, in cooperation with BGP, has completed the acquisition of the Triok broadband non-exclusive 2D seismic survey in the Northern Basins of Papua New Guinea.Following the acquisition of the Solomon Sea non-exclusive 2D in the northern basins of Papua New Guinea, the Triok broadband non-exclusive 2D seismic survey consists of 3,845 km (2,389 mi) of 2D long-offset, high-resolution, broadband seismic and offers regional coverage of the Cape Vogel basin and Huon Gulf.Andrew Weller, Asia-Pacific Manager for Searcher Seismic, said the survey will be the key to unlock several questions and

The latest visco-acoustic (“Q”) velocity modeling and seismic imaging technologies have been applied to BroadSeis broadband variable-depth streamer field data, acquired between 2014 and 2016. The final output forms a contiguous data volume covering 35,400 km².The Northern Viking Graben, like many other areas around the globe, contains a wide range of localized near-surface geological anomalies – with shallow

the seismic sources and the seabed receivers, 4-component (4-C) sensors – results in better seismic data quality than can be acquired with towed streamers,” said Midenet. “Ocean bottom data acquired with geophones and hydrophones, first described in the 1950s, was the original marine broadband acquisition technique and was used extensively in the 1980s, predating towed streamer broadband methods by more than 20 years. The combination of vector (geophone) and scalar (hydrophone) sensors allows the down-going reflection from the sea surface, known as the sea surface ghost, to be removed
