VENATIC OFFERS AN Attractive Proposition to Operators

  • In certain cases, surveys may be undertaken for equity i.e. no cost to existing permit holders
  • Reportable operational activity (may assist in commitment negotiations with regulator)
  • Study will assist in identifying potential hydrocarbon sources in water column
  • Effectively ground-truths anomalies high-lighted by satellite and radar
  • Nature of survey allows real-time re-configuration of survey to investigate specific anomalies
  • As appropriate, surface water sampling can be added to survey program
  • Confirmation of seep data reduces exploration risk and improves any marketing efforts

TECHNOLOGY PARTNER - Blue Ocean Monitoring

Global leader in oceanic geochemical surveys / seep detection using Teledyne “Slocum Gliders”

The Slocum Glider is a buoyancy-driven electric glider which enables long range and duration remote water column observation for a range of applications.  The glider can be deployed and recovered from any size vessel with minimal time on station. Once deployed, it can easily be controlled from anywhere in the world through the use of web based piloting tools. Slocum gliders can run pre-programmed routes, surfacing to transmit real time data to shore while downloading new instructions at regular intervals. This allows fleets of gliders to be operated remotely with minimal personnel and infrastructure.
The buoyancy propulsion drive provides months of performance at sea and the optional thruster provides up to 2 knots of horizontal speed. This long endurance glider will expand the data collection range and/or situational awareness by providing real data over extended periods of time.
No matter the sea state, gliders are capable of continuous sampling without risking personnel or costly assets. Slocum gliders routinely operate around the world in extreme weather conditions.
The gliders are modular, with over 40 sensors and other options available to address a wide variety of ocean conditions and sampling requirements.
Slocum gliders enable high resolution sampling over transects that can be revisited during a single deployment. This enables resolution of sampled features over time and space at a substantially lower cost than with traditional methods.
For oil and gas seep detection surveys, the gliders are equipped with a Hydrocarbon Detection Package, including methane and oil-in-water sensors.

Hydrocarbon Seep Detection

The illustration below on the left shows the route traveled by oil leaving the subseafloor reservoir as it travels through the water column to the surface and ultimately sinks and falls out in a plume shape onto the seafloor where it remains in the sediment.

The illustration below on the right demonstrates how the glider operates in the water column. The case study shown on this website indicates how the glider, by extensively sampling the water column, can identify a seep.
