ADVANCING
MARINE SEISMIC EXPLORATION
Kietta reimagines the approach to seismic acquisition for offshore oil and gas exploration, developing extremely efficient patented technologies capable of producing the highest quality data at a price point that meets the evolving needs of the market.
aUTONOMOUS vESSELS, HIGH-RESOLUTION DATA
Kietta’s Free Cable™ system replaces the giant vessels and towed streamer arrays of traditional seismic with a swarm of small autonomous, remotely controlled pods and cables, equipped with state-of-the-art recording sensors.
Free Cable™ offers a revolutionary new approach that combines the productivity of towed streamers with the data quality of sea bottom systems. Independent, robotically-controlled cables are spread out at mid-water depths. A source boat navigates over the cables, providing a full azimuth long offset dataset very similar to land acquisition in terms of coverage and binning.
A better way
for 4D Seismic
Until now, the only way to get high quality data in areas with dense surface production facilities was to deploy expensive and slow sea bottom acquisition systems, using cables or nodes.
Free Cable™ redefines 4D seismic by delivering high data quality with full azimuth and offset coverage supported by real-time data QC, while staying clear of sea-bottom and surface infrastructure.
FreeCable™ deploys a full-size array of zero-buoyancy cables at depths of up to 100m. At such depths, below wave noise, and without motion flow, the recordings show an impressively high signal-to-noise ratio and a broadband frequency spectrum.
The observer controls the positioning and depth of the sensor array, and seismic data transmitted back to the control vessel in real time ensures that the system is fully operational and the coverage and data quality meet or exceed customer specifications.
Sustainability
built in
Environmental protection is central to our operations from planning to completion. The small Remote Autonomous Vehicles (RAVs) consume minimal fuel and are mostly stationary, resulting in a low-carbon footprint operation.
The high signal-to-noise ratio of the receivers allows shooting with smaller sources, reducing impact on marine mammals and fisheries. The equipment does not touch the sea bottom, preserving coral reefs and other sensitive sea-floor fauna and flora.
