Technology Highlights
Technology – Zerlux AS provides innovative downhole high-power laser and fiber optic solutions for the most pressing challenges encountered during Oil & Gas production. The Downhole Laser Pipe Cutting technology, currently in its prototype phase, aims to replace costly and hazardous pipe cutter tools with precise, eco-friendly, and controlled laser light.
Advantages – Laser technology allows for Precise and Controlled cutting while providing Immediate Feedback on the cutting process. It is also an Environmentally Friendly technique that does not use any hazardous materials, chemicals, or explosives. Additionally, the laser cutting process does not involve any mechanical contact between the cutter head and the pipe, which reduces the risk of the cutter getting stuck.
Zerlux AS is a company with expertise in the oil and gas upstream segment, owned by Subsurface AS and Zerlux Hungary Ltd, both of which have over 100 years of experience in the industry.
Parent companies primarily design, manufacture, and commercialize downhole products for Well Intervention and have partnerships with major international and small local operators and service providers. Zerlux AS focuses on research and development (R&D), specifically in designing, manufacturing, and commercializing advanced laser-optic down-hole laser tools for offshore and onshore applications in the oil and gas sector.
Smart Crossover Technology
Smart crossover is run on slickline as a gauge run to give a firsthand review of your well conditions.
Smart Crossover Tool
Fishing Operation (s-LIB)
- Inclination and Orientation Measurement of the LIB during impact
- Off-axis Center Offset Measurement of the LIB during impact
Innovations on Tubing ID Changes (s-Tube)
- Variation in steel diameter during run indicates Pipe Collapse or Corrosion.
- Measuring the thickness of low side Scale, Paraffin or other Built Up.
Innovation on Identifying Tubing Jewelries (s-Object)
- Identifying the location and position of side objects like Side Packet Mandrel or other Tubing Jewelries.
