Ace Well Technology

What Ace Well Technology does

Ace Well Technology AS is a Norwegian downhole technology company founded in 2012 and headquartered in Randaberg, Norway, with sales offices in Houston and Kuala Lumpur. The company designs, manufactures, and sells patented tools built around the Ace Ratchet Collar (ARC) platform, whose unique ratchet locking mechanism delivers axial holding force of 90,000lb minimum (tested to 180,000lb) irrespective of pipe weight, grade, or thread. ARC underpins a portfolio spanning well construction (ARC, ARC-Slim, ARC-Force, ADC, AFC) and completions (ACLC for automated control line clamping, ASC as a splice-carrier replacement), with products validated through deployments for operators including Equinor and field-tested across more than 40 countries.

The company pursues a hardware-sales revenue model, shipping proprietary tools directly from manufacturing to operators and service companies worldwide, supplemented by a channel partnership with R&D Solutions in Australia and remote installation and training services. Customer concentration is enterprise-skewed: Norwegian, Brazilian, Australian, Middle Eastern, and other national operators and majors use ARC, ARC-Slim, ACLC, and ADC for casing centralization, control line management, and drilling-through-problem-zones applications. In January 2025, Ace was acquired by Varel Energy Solutions (VES), integrating ARC and ACLC into VES's cementing equipment and smart completions offering. The August 2025 first-of-its-kind remote-controlled clamp installation on the Norwegian Continental Shelf, executed jointly with Expro (RCIS) and drilling contractor Archer, exemplifies the company's safety-and-automation-led value proposition.

Core offering

Ace Well Technology manufactures and sells patented downhole tools for oil and gas well construction and completion, anchored by its Ace Ratchet Collar (ARC) platform. The product family includes stop collars (ARC, ARC-Slim, ARC-Force), the Ace Control Line Clamp (ACLC), Ace Drilling Centralizer (ADC), Ace Splice Carrier (ASC), and Ace Fixed Centralizer (AFC), sold directly to operators and service companies globally with engineering and installation support services.

Product overview

Ace Well Technology offers a suite of downhole tools anchored by its patented Ace Ratchet Collar (ARC) technology, which provides unrivalled holding force for well construction and completion operations. The core ARC platform includes the ARC-Slim (90,000lb+ rated, first in market) and ARC-Force (compact variant with 50,000+ lbs holding force). The product family extends to completion tools including the Ace Control Line Clamp (ACLC) for automated control line installation, Ace Splice Carrier (ASC) as a splice sub replacement, and the Ace Drilling Centralizer (ADC) for rotary drilling applications. All products leverage the ARC's unique ratchet locking mechanism and are designed for easy remote installation with minimal environmental impact.

Products and services

• Ace Ratchet Collar (ARC) The patented ARC platform and ratchet-locking stop collar providing unrivalled holding force for attaching tools and accessories to casing or completion strings during well construction and completion. Minimum axial holding force of 90,000 lb, tested to 180,000 lb, independent of pipe weight, grade, and thread. Sold to oil and gas operators and service companies.
• Ace Ratchet Collar Slim (ARC-Slim) The first 90,000 lb+ rated stop collar on the market in a slim, efficient design. Fits any size or grade of API pipe and is suited for close-tolerance applications where space is constrained. Sold to oil and gas operators.
• Ace Ratchet Collar Force (ARC-Force) A more compact collar option delivering extraordinary holding force of over 50,000 lbs, providing flexibility for different well requirements. Sold to oil and gas operators and service companies.
• Ace Control Line Clamp (ACLC) An automated control line clamp that enables fully automatic installation, improving safety by eliminating red zone exposure during completion running. Achieves 15-16 joints per hour peak running speed, reduces time in red zone by 30%, and reduces personnel required by 50%. Sold to oil and gas operators and service companies.
• Ace Drilling Centralizer (ADC) A solid body centralizer that rotates independently of the casing or liner string, used for drilling through problem zones in casing and liner drilling applications. Axial holding force rated up to 180,000 lb. Sold to oil and gas operators and service companies.
• Ace Splice Carrier (ASC) A slip-on product providing superior cable protection and securely housing splices for multiple control lines, replacing splice subs and reducing rig time by 6-8 hours per assembly. Compatible with hydraulic, electric, and TEC splices of all completion vendors. Sold to oil and gas operators and service companies.
• Ace Fixed Centralizer (AFC) A fixed centralizer successfully trialed for land wells in the Middle East, providing centralization for casing strings in various well construction applications. Sold to oil and gas operators.
