What TCO does

TCO AS is a Norwegian specialty oilfield services and equipment company that designs, manufactures, and deploys downhole well completion and intervention technologies for upstream oil and gas operators. Founded in 1999 in Voss as Total Catcher Offshore (rebranded to TCO in 2001), the company originated in fishing-and-retrieval services for stuck downhole equipment before pivoting into proprietary intervention-free completion technology.

TCO's product portfolio centers on four differentiated technology families. First, laminated glass barrier plugs (TDP series), including Mill Open, Pump Open, Remote Open (NonEx), and HPHT variants with dissolvable glass disc technology that disperses into fine, compatible granules for full-bore access, with 8,000+ cumulative installations worldwide. Second, chemical injection systems (HN, FN, FA, FNR, and Q-Series modules) — claimed as the world's only API 19CI qualified injection system, addressing corrosion, scale, and flow assurance. Third, the patented Annulus Pressure Relief System (APRS) with gas-tight check valves and integrated filtration, ISO 14998 V0 certified and qualified to Equinor TR2385. Fourth, Tubing Conveyed Perforating (TCP) services for plug-and-abandonment and reservoir perforation, in which TCO pioneered TCP P&A in Norway in 2012.

Commercially, TCO operates as a B2B supplier selling proprietary downhole products (one-time durable-goods model) and TCP services (professional services model) via a direct enterprise field sales organization with regional offices covering North America, South America, UK, Africa, Middle East, Asia Pacific/Caspian/Australia, and Europe. Pricing is quote-based and not publicly disclosed. The company employs 101-250 people, serves tier-1 operators including Equinor/Statoil, Shell, BP, ConocoPhillips, ENI, Apache, Edison, and Caspian/Middle East operators, and was acquired by Innovex International in July 2026 for $95 million in a cash and stock transaction.
