Following is a short video demonstrating our containerized node storage unit with fully automated data download, clock and battery management. The system handles one node in or out every 16 seconds from a 40´container. In the video, we sped up the off loading process for illustration purposes. Also important to note that the nodes will continue on conveyor belts to the launch module on customer installations for completely free hands-free operations.
We are excited to be announcing a major product upgrade being readied for implementation in H1 2019 which will give our Venator node-based seabed seismic solution a strong competitive advantage over current node-on-a-rope (NOAR) systems.
Highlight of the changes, based on the company’s continuing R&D programme, will be Venator’s ability to safely deploy and retrieve nodes at speeds of more than 9 knots. Along with numerous other improvements, this will further solidify Venator’s technology as by far the most cost-effective seabed acquisition system on the market today.
Based on experience from our successful sea-trials with our customers and oil companies in the Caspian and North Seas we have now developed the launch and retrieval system to work even better at high vessel speeds. Operating at 9 knots or more is possible, a major enhancement from Venator’s already proven 6 knots. We have also worked to make the system more compact and robust.
Below we list the details of the many significant advances in the system’s node, automation and data management capabilities available in H1 2019, all of which are designed to make Venator the technology choice for seabed seismic acquisition going forward.
Venator: The upgrades
Node and battery
− The A3000 node can now be delivered with a low cost OCXO clock with no reduction in battery life between charging. inApril’s solution for improved clock accuracy improves the sampling accuracy by a factor of up to ten times.
− An improved built-in battery management module gives the operator superior control of batteries and charging.
− The new release can transmit a node status to a surface vessel via the built-in transponder.
− A new control system manages the rope speed for constant seabed tension during deployment and retrieval.
− Ability for simultaneous retrieval of two receiver lines for increased retrieval efficiency
− A new and more efficient node washer
− Simplified and faster node storage. Data download, battery charging and clock management are parallel processes in inApril’s storage solution.
− Fully scalable. More nodes just require more of the same hardware (same software)
− Enhanced QC
inApril is happy to announce that our proprietary Venator technology has passed further field trials.
As part of a prequalification process a number of inApril’s A3000 nodes, along with other Ocean Bottom Seismic technology, was tested during a field trial.
The nodes were deployed by ROV and recorded continuous data during approximately 45 days in the field. The subsequent analysis of the data confirmed that all A3000 nodes performed according to specifications and expectations.
inApril is pleased to announce the appointment of Pierre-Loïc Laizet as Vice President Technical, effective September 1. Pierre started his career assembling wireline tools with Schlumberger in Paris, then moved to Norway and Malaysia with WesternGeco in engineering and manufacturing of marine and land seismic hardware. Combined with experience in sourcing and supply chain management, he has acquired a wide range of technical expertise in the manufacturing of seismic systems. His latest position was Technical Manager for Malthus Uniteam, focusing on modular and containerized solutions for the oil and gas industry. He is a French citizen and resides in Norway.
As reported by DNB and published on Bloomberg chat June 7.
“TGS CEO Kristian Johansen held an industry talk/webcast this afternoon. One of the focus points was on new technology and he spent a considerable time on the node/ocean bottom seismic development. TGS see a trend of new ocean bottom seismic companies emerging with lower cost solutions and they expect that this will continue going forward to a more competitive level versus traditional streamer surveys. On numerous occasions the CEO commented that the ocean bottom development is something they follow very closely, to a level where they are already working with some of the leading players and that this could be the future of the seismic industry. According to TGS, ocean bottom should be the highest growth area going forward and oil companies have a higher appetite for this survey method now. Ocean bottom surveys are still more expensive compared to traditional towed streamer surveys, however, the data quality is significantly better. This development is getting increasing attention in the industry, and could be a risk for both traditional vessel owners but also the value of existing conventional 3D multi-client libraries.”
Excellent and well researched commentary in the January First Break issue regarding the current technology shift underway in the marine seismic market. If you are at all interested in Marine Seismic this is an excellent summary of why Ocean Bottom Nodes are gaining market share today and why they are destined to be the primary technology in the near future.
We are posting here a summary of an OBS market study by Oslo-based independent consultant Arkwright Consulting AS. It confirms the expectation on which inApril was established in 2012, namely that increasingly cost-effective ocean bottom seismic (OBS) acquisition technology will continue to gain market share for marine seismic surveys. Arkwright´s research indicates that OBS will grow by 250% within 2019/2020.
Some of the graphics provide a clear picture of why inApril’s innovative approach to reducing costs and speeding operations, based on a high degree of automation, exactly meets the needs and preferences of the offshore E&P industry going forward. It is clear from this report that inApril can successfully challenge towed streamer solutions to multi-/wide-azimuth and other seismic surveys involving complex geology, as well as provide high quality multi-component data for reservoir characterization.
The Norwegian seismic equipment supplier inApril AS announces that it successfully carried out a full-scale sea trial of its fully integrated node-based seabed seismic acquisition system, Venator. The company says the trial confirmed that Venator is the first seabed-based exploration tool to provide data far superior to conventional towed streamer solutions at competitive terms.
The system, which features fully hands-free handling and flexible node spacing at unprecedented speeds, was tested in 110m water depth over a part of the Edvard Grieg field (PL 338), operated by Lundin Petroleum, in the Norwegian North Sea. The node used was inApril’s A3000 node, suitable for both deep and shallow water operations.
The trial repeatedly demonstrated ‘node-on-a-rope’ deployment speeds of 5 – 6 knots and retrieval speeds at 3 – 4 knots in these water depths, enabling up to 20 km² full-azimuth data acquisition per day in exploration mode.
Preliminary results confirm the excellent data quality also shown by previous sea trials, only achievable by seabed data acquisition. Data processing will be carried out in the coming weeks.
According to numerous industry executives and analysts, more efficient node-based ocean bottom seismic will provide the optimal solution for oil companies looking to increase reserves at reasonable costs via targeted exploration and reservoir characterization data acquisition.
Vidar Hovland, CEO of inApril, said: ‘The market has been waiting to see if we can deliver what we promised. Now we have documented that Venator offers a game-changing, cost-effective, and fully automated exploration and reservoir characterization tool. The system is flexible and can be containerized for mobilization to a variety of vessels for a range of offshore seismic applications and water depths.’
Following is our abstract paper presented by Ronny Bøhn at the SEG OBN Technologies and Applications Workshop in Beijing.
The paper considers the high cost and operational inefficiencies traditionally associated with ocean bottom seismic (OBS) acquisition that have deterred wider industry adoption of this compelling technology. A case study is presented on how the main challenges are being overcome in the development of a next generation ocean bottom node (OBN) system focused on lower cost and more efficient, faster operation with scope for exploration projects as well as reservoir characterization and monitoring.
