What Petroleum Technology Company does

Petroleum Technology Company (PTC), operating commercially as Petrotec and aligned with the Interwell product brand, is a private oil services firm founded in 2002 and headquartered in Stavanger, Norway, with subsidiary operations tied to Al Mahhar Holding Company in Qatar. The company designs, manufactures, and delivers well integrity technology solutions for the upstream oil and gas industry, with a portfolio organized across six solution areas: Wellhead Integrity, Casing Barrier Solutions, Completion, Intervention, Plug & Abandonment, and Renewables & Low Carbon. Its technology stack is built around proprietary downhole tools and barrier systems, including RockSolid (a thermite-based permanent abandonment barrier), VR Sensor, MSAS (Master Surface Annulus Safety Valve), A-Pro, IRBV (Inter Remote Bypass Valve), CannSeal ZonalSeal epoxy technology, and continuous pressure/temperature monitoring systems — many designed to ISO standards and targeting regulatory compliance across well lifecycle stages from completion through abandonment.

The business operates a product-led, sales-driven GTM centered on direct enterprise engagement with global oil and gas operators. Revenue is generated through the sale of well integrity products (plugs, packers, barrier systems, monitoring equipment) alongside custom engineering services addressing specific well challenges such as water shut-off, wellhead integrity assurance, and plug & abandonment. Customer engagement is collaborative and project-based, with operators submitting well challenges for tailored solutions. The company demonstrates global reach via case studies spanning Africa and Europe, and through its Qatar-linked subsidiary has extended into Middle Eastern energy infrastructure. Capital history includes a 2013 financing round with Nordic private equity firm Herkules Capital.

Products and services

• RockSolid Thermite-Based Plug & Abandonment Barrier RockSolid is a thermite-based permanent abandonment barrier technology that melts all well elements and solidifies to reinstate caprock integrity, providing a rigless, single-run alternative to traditional slot recovery and mechanical P&A methods for oil and gas operators.
• Retrievable Bridge Plugs Retrievable Bridge Plugs provide reliable temporary zonal isolation for demanding wells including high-pressure/high-temperature environments and complex well geometries, sold to oil and gas operators for intervention and abandonment applications.
• Plugs & Packers Plugs & Packers are wellbore isolation solutions with retrievable and permanent options that ensure secure sealing and anchoring in demanding downhole environments for oil and gas operators.
• Glass Barrier Plugs (IRBV & IRSV) Glass Barrier Plugs include the Inter Remote Bypass Valve (IRBV) and Inter Remote Shatter Valve (IRSV), providing remotely operated, pressure-cycled barriers that improve well performance, reduce wireline interventions, and tolerate extreme conditions for subsea and complex wells.
• Straddle Solutions (APS, IVC, ISV) Straddle Solutions are flexible intervention tools including the Anchored Production Straddle (APS), Insert Valve Carrier (IVC), and Injection Safety Valve (ISV), used for production control, safety valve retrofitting, and tailored well intervention by oil and gas operators.
• Flow Control Products (ISV & IBV) Flow Control products include the Injection Safety Valve (ISV) for water injection stabilization and the Intelligent Barrier Valve (IBV) for remote-controlled operation, supporting well efficiency, integrity, and production optimization for operators.
• Setting Tools (EST & HRT) Setting Tools include the Electronic Setting Tool (EST) and Hydraulic Running Tool (HRT), used by operators and service crews to install downhole isolation devices with control, versatility, and efficiency.
• Data Acquisition Systems Data Acquisition Systems provide real-time wireless downhole monitoring using acoustic communication with up to 10 years of monitoring capability, used for barrier verification and integrity management by oil and gas operators.
• Chemical Injection Systems (SureFlo) Chemical Injection Systems include the SureFlo range, which tackles U-tubing effects and unstable flow with anti-U-tubing protection and dual back check systems for scale and corrosion management in producing wells.
• Side Pocket Mandrels (NexLift Series) Side Pocket Mandrels include the NexLift Series, designed for modern gas lift operations to improve well integrity and reduce intervention needs for oil and gas operators.
• Gas Lift Solutions (GLVs & Retrofit Systems) Gas Lift Solutions include Gas Lift Valves (GLVs) and retrofit systems that improve production efficiency, well integrity, and long-term well performance for oil and gas operators.
• Annular Sensor System The Annular Sensor System monitors wellhead integrity with continuous pressure and temperature checks, reducing costs by eliminating traditional valves and providing autonomous and manual pressure management capabilities for operators.
• Surface Annular Systems (MSAS & HSAS) Surface Annular Systems include the Master Surface Annulus Safety Valve (MSAS) and Hydraulic Surface Annulus Safety Valve (HSAS), which create independent barriers meeting regulatory standards and mitigating sustained annulus pressure risks at the wellhead.
• Annular Isolation Solutions (CannSeal ZonalSeal) Annular Isolation Solutions use CannSeal ZonalSeal patented epoxy technology for precise annular seals that reduce water production in vertical and horizontal wells, deployed via standard electric wireline.
• Plug & Packer Add-Ons Plug & Packer Add-Ons enhance well integrity with secure isolation, flow direction management, and advanced control features, complementing the company's downhole isolation product lines.
