Sealing the Past, Unlocking the Geothermal Future
Critical Challenges in the Energy Transition
Ensuring the success of the energy transition a range of initiatives are needed, that require a series of heavy-duty jointed pipe interventions, including pulling pipe, conveying rotation, pumping, conducting downhole measurements, and maintaining continuous well control.
Phasing out millions of wells
Millions of non-productive wells need to be safely decommissioned to prevent environmental hazards.
Supporting geothermal energy
The transition to geothermal energy requires significant support to become a viable and widely adopted alternative to traditional energy sources.
Repurposing depleted wells
Instead of closing wells, some could be reused for applications such as geothermal energy, CO2 injection, or gravity-based energy storage systems.
Introducing: The Mighty Mantis (patent pending)
The current landscape of automated solutions often involves large footprints and extended rig up times, making them less practical and often overdimensioned for many operations. More compact solutions, on the other hand, require personnel to work directly atop the well, presenting significant safety risks and operational challenges.
We firmly believe in the potential of Hydraulic Workover Technology (HWU) as a critical enabler for these complex interventions. Imagine transforming well operations into a streamlined, efficient, and eco-friendly process. Meet the Mantis, our advanced hydraulic workover unit designed to seal the past and unlock the geothermal future.
Increased Safety
No more people permanently on the well
Reduced Man-hours
Crew size you expect during a wireline operation.
Reduced Environmental Impact
Low stack height, volume, and weight which affects the value chain.
Lower Energy Consumption and Emission
On-demand system with lower sound emission.
Rapid Rig Up
Reduction of lifts and installation of parts.
Automation
Automated, yet compact and cost-effective
Reduced waiting on weather
Risks and exposure greatly reduced
Autonomous wireline
Self supported wireline rig ups
NORSOK compliant
Our production model will comply to NORSOK
MVP specifications
Our collaborative testing with customers begins with simple wells and progresses to more complex scenarios. Initial field tests validate core functionalities and safety on the least complex wells. As complexity increases, we test adaptability and efficiency on moderately complex wells, culminating in proving capability on the most challenging wells.
Lessons learned from MVP tests will refine our production model, enabling comprehensive well management—from tubing pulling to annulus remediation and casing extraction. The envisioned specs of the NORSOK compliant production model, with larger pull, will be shared early 2025.

Great presentation and very interesting. My view: this is what the industry needs.
Martin Straume
Discipline Lead P&A AkerBP
While there are many efforts towards smart downhole innovations, the reality is that we still need to pull tubing. In Norway, safety regulations to protect personnel from injuries require us to handle/operate all tubings and workstrings in and out of the well remotely. Today, only rigs possess that technology. The Mantis, with its light weight and remote operational ability, aligns exactly with what the industry is seeking for tubing pulling.

Super creative concept that seems to be quite fit for purpose and also complimentary to evolving technologies.

Your case is strong if it can work on smaller platforms without a JUB or W2W vessel next to it because then tripping speed will matter.
