Based on requests from customers inApril now introduces the A3000LL (long life) node. The A3000LL has extended battery life (125, 150, 175 or 200 days). All specifications except for battery life, weight and size will be the same as for the A3000. An A3000LL with 200 days battery life will have a weight of 35/15kg (air/water). Please contact us for more details.
inApril has signed a technology cooperation agreement with 4CNode Geophysical, a Norwegian company developing a node-based system mainly for reservoir characterization and monitoring. 4CNode will use inApril`s technology in their nodes and for data management and several quality control solutions.
4CNode Geophysical, founded by Eivind Berg, legendary pioneer of the first commercial ocean bottom node survey in 2003, is designing a seabed node application using separately planted 4-component sensors.
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.
