Ace latest products

Stavanger, 26 January 2021​

  • Delivers an extremely high holding force for non-close tolerance operations, with no impact on drift

  • No loose parts

  • Quick and easy to install

  • No pipe preparation or transportation required


Ace Oil Tools, the oil and gas technology company known for its proprietary ‘ratcheting technology’, has launched its new ARC-Force product to the stop collar market.


Based on the well-known Ace Ratchet Collar Slim (ARC-Slim), the updated and patented 2-piece collar uses a proprietary ratchet mechanism, press fitting the two sets of ratchets together to permanently lock the collar to the casing.


The ARC-Force is small in size but big on strength, with a holding force of 50,000 lbs. It includes zero loose or moving parts and has no impact on drift, while its availability for quick delivery means no long wait to impact production costs.


The ARC-Force joins the family of Ace Oil Tool’s ARC products. Its Ace Rachet Collar the ARC-slim, delivers unrivalled holding force under all operating conditions. The ARC-slim is the first 90,000lb+ rated stop collar on the market.  Uniquely designed, Ace’s ARC products mount downhole accessories directly to the outside of the casing or completion string.


While Ace’s ARC-Slim is made for close tolerance applications, the ARC-Force is a cost-effective solution for non-close tolerance operations and is based on patented and field proven technology.


Its size at 6.5mm allows it to fit into most applications worldwide. It is manufactured from 4140 steel or chrome materials, with non-standard materials available on request.

Espen Sørbø, CEO of Ace Oil Tools, said:

“We constantly review market requirements and knew there was demand for a small, yet strong, stop collar. We are delighted to bring the ARC-Force to the market as it will offer something different from our current offering, ensuring those looking for a short, cheaper stop collar alternative have something to meet their needs.


“Our core goal has always been to be a holding force in downhole technology. During 2020, we have focused our efforts in driving forward our new, innovative products and we bring our new ARC-Force to the market at a time when the sector needs it most. We look forward to continuing our work with operators and companies to deliver cost-effective, unrivalled holding capabilities.”

Ace Oil Tools is an oil and gas technology company that has redesigned the traditional stop collar to bring unrivalled holding force to operators looking to centralise the pipe and protect equipment downhole. Smart and cost-effective, the Ace Ratchet Collar (ARC) removes the need for centraliser subs, resulting in cost savings of up to 80%. 


Founded in 2012, Ace Oil Tools has carried out projects in more than 28 countries and five continents. The company has a growing product portfolio, with all of its products built on its proprietary ‘ratcheting’ mechanism, which is simple and innovative in design.
