inApril works under strict ethical standards and will always before a sale inform customers of what we know when it comes to other’s IP and patents.

To reduce the risk of anyone, intentionally or unknowingly, trying to patent elements of our Venator solution or ways of operating, we actively use our web page and EAGE / SEG exhibitions to make these elements public.  To learn more about our IP and patent policy visit https://www.inapril.com/ip-patent-policy/

Venator solution

The Nodes
The A3000 node is designed to meet the requirements for all types of nodal operations, whether for cable or ROV deployment. However, we also deliver nodes for special markets such as transition zones. Some of our nodes have electronics and sensors in separate pressure compartments.

 As has been illustrated in all illustrations published by us, the node is slightly off center weight balance when attracted to the rope. This is to avoid the node from rotating around the rope during deployment and recovery. The imbalance works like a rudder and will stop the node from rotating.

Rope or Cable
Venator is currently designed for rope with a central core payload for the right buoyancy. However, replacing the node’s ‘rope latch’ mechanism may allow the use of other cables such as steel wire. Replacement can be carried out without the need to open up the node’s pressure compartments.

Venator does not use expensive rope termination joints – rope sections are joined together by means of conventional rope splices. This approach was taken because it adds no cost, is quicker to connect, provides a stronger solution and is more flexible in use.

The Venator nodes can operate in different recoding modes. These include:

  1. Recording starts as the onboard charging power is disconnected and continues until the charging power is connected again.
  2. Recording starts when the node has been steady on the seabed for a set time. The recording may also be programmed to stop again when the node detects that recovery has commenced.
  3. Recording starts after a fixed time from when the node has been deployed from the vessel. The recording may also be programmed to stop again when the node detects that recovery has commenced.

The nodes record and store an RMS value of all four channels at regular intervals in addition to an accumulated RMS. This is used for QC of the data in the data management system.

Data Management System
In addition to its normal task of taking care of the data from the nodes, the Venator data management system also performs the following tasks:

  1. Keeping track of locations and status of all nodes at all times.
  2. Selecting the sequence of nodes to be deployed and where the nodes shall be docked once recovered.
  3. Controlling the rope speed and node intervals/positions on the rope.

The Venator data management system is designed for ‘hands-free’ operations. The flow and processes are mostly automatic and the focus is on monitoring and QC.

Venator has all nodes connected with power, data communication and a clock synchronization signal at all times while onboard. This means that the clock will normally never be switched off, which again improves the stability of the clock significantly over time. The nodes do however have a ‘standby mode’ for longer storage (ex. Onshore storage).

A standard Venator system has sufficient docking positions/slots for all nodes. The nodes can dock in any docking slot.  Venator uses a ‘crane’ to move nodes between docking slots. The ‘crane’ can carry two nodes at a time, is not linked to any carrier system and can only move nodes between different slots.  Dummy docking-slots are used for pick-up and delivery of the nodes. Nodes are pushed or pulled in or out of the dummy docking-slot(s). The ‘crane’ moves nodes between a dummy slot and a ‘real’ slot. The sequence can be to move nodes via dedicated slots for clock sync/drift and/or data downloading before being moved to a parking slot. The parking slots have power, data communication and a clock sync pulse.

Positioning Transponder
The built-in transponder can operate in different modes to extend the battery endurance. These modes are, but limited to:

  1. Always powered as long as the onboard external charging power is disconnected.
  2. Powered from when the onboard charging power is disconnected (deployment) and until it has been stable on the seabed for a set time. The transponder power in this mode will normally be programmed to come on again if the node experience movements (typically, but not necessarily, recovery).
  3. In combination with point two above there are options to preprogram the power to come on at certain times or under certain conditions while on the seabed.
  4. In mode two and three above the power will remain on for a set time after the last interrogation from the vessel.

Oslo, 3rd August, 2016:  inApril is pleased to report an oversubscribed private placement with lead participants being professional investors focusing on the Seismic and Oil & Gas markets.  Proceeds will be used  to advance our commercialization efforts.

Oslo, 30th June, 2016: inApril, the Norwegian offshore technology company, announces today a first commercial agreement potentially worth $25-30 million for Venator, its game-changing, node-based seabed seismic acquisition system.

A letter of intent (LOI) has been signed with the Kazakhstan company GEO ENERGY GROUP LLP (GEG) to supply a Venator system, starting with a test project this autumn in the Caspian Sea. GEG will tender inApril’s Venator system in bids for upcoming major ocean bottom seismic (OBS) contracts.

Last year GEG acquired the interests of Petroleum Geo-Services (PGS) in PGS-Khazar to expand its offshore seismic services within Russia and internationally.

Vidar Hovland, CEO of inApril, said: ‘We welcome this big step in bringing Venator to market. It marks the beginning of a new generation of independent accessible OBS technology.  Oil companies and contractors have long recognized the benefits of the high quality data possible from seabed seismic, but have been put off by the acquisition cost of existing cable and node acquisition technologies.’

‘Venator is a genuinely disruptive technology. It provides the safe, highly automated, rapid acquisition that companies have been waiting for – at significantly lower cost than existing systems.’
Vladimir Telbukhov, CEO of GEG, said: ‘We are pleased to become an early adopter of inApril’s technology. The Venator system’s obvious benefits in cost, efficiency and safety will be of great help in building our company’s seabed seismic acquisition offering and gaining highly competitive position in the market .’
In development since 2012, the Venator node-on-a-rope system, designed to handle more than 10,000 seismic nodes from one vessel, features an unprecedented level of efficiency and hands-free automation.
