What Interwell does

Interwell AS is a Norwegian oilfield services company specializing in well integrity solutions across the well lifecycle — from completion through intervention to plug and abandonment. Founded in 1992 and headquartered in Stavanger, the company designs, manufactures, and deploys proprietary mechanical barrier technologies, wellhead safety valves, downhole sensors, and integrated monitoring systems. Its flagship technologies include RockSolid™, a thermite-based permanent P&A barrier that creates a rock-to-rock gas-tight seal in a single wireline run; the MSAS™ fail-safe closed barrier valve family; VR Sense™ annulus pressure/temperature sensors; the iDT acoustic wireless downhole monitoring transponder; and the A-PRO™ annulus pressure management platform. The portfolio spans bridge plugs, packers, gas-lift systems, chemical injection, and intervention tools, complemented by the 2020 acquisition of CannSeal's epoxy annular isolation line and the prior integration of Petroleum Technology Company.

The company operates a B2B enterprise field-sales model, deploying technical sales engineers and field-service personnel directly to oil and gas operators globally. Revenue is generated through three streams: sale of specialized well-integrity products, integrated well-intervention and P&A services executed by field engineers, and recurring data-acquisition and monitoring services via iDT and A-PRO deployments. Customers are upstream oil and gas operators (offshore and onshore) plus gas-storage operators, with named reference accounts including ADNOC Offshore (Upper Zakum), Nigerian, Malaysian, Canadian, Qatari, Omani, Danish, German, Italian, and Norwegian Continental Shelf operators. Pricing is quote-based and project-specific with multi-year contracts. Products are qualified to ISO 14310 V0, API 6A/6FD/6FB/14A, NORSOK D-010, and ATEX standards, and the company has held UN Global Compact signatory status since 2019 with a stated net-zero-by-2050 target.

Core offering

Interwell designs, manufactures, and sells proprietary well integrity products for the oil and gas industry, including barrier solutions (RockSolid™, MSAS™, bridge plugs, packers), downhole monitoring systems (VR Sense™, iDT, A-PRO™), and flow control valves (IBV, IRSV, IRBV). The company also provides integrated well intervention, barrier installation/verification, and plug & abandonment (P&A) field services executed by deployed engineers globally.

Product overview

Interwell is a specialized oilfield services company offering a comprehensive portfolio of well integrity solutions across five core segments: Wellhead Integrity, Casing Barrier Solutions, Completion, Intervention, and Plug & Abandonment. The product portfolio centers on mechanical barrier technologies (bridge plugs, packers, valve systems) augmented by monitoring and control systems. Key product families include the RockSolid™ thermite-based P&A barrier technology, MSAS™ and VR Sense™ wellhead safety and monitoring systems, A-PRO™ annulus management platform, and various retrievable bridge plug lines (ME, HEX, HPHT, MP, THEX). The company also offers intervention tools (IBV, IRSV, straddle systems), setting/retrieval tools (EST, HRT, VR-Tool, MSP), and data acquisition systems (iDT, BVS, gauges). Products are designed to work individually or as integrated solutions, with monitoring systems capable of integrating with operator SCADA infrastructure. Interwell serves global offshore and onshore markets across Europe, Americas, Middle East, Africa, and Asia Pacific.

Brands

• Petroleum Technology Company (PTC): Company now integrated into Interwell, specializing in VR Sense and MSAS wellhead integrity solutions for annulus monitoring and barrier management.

Products and services

• RockSolid™ Permanent P&A Barrier Permanent plug and abandonment barrier technology that creates a bismuth-alloy rock-to-rock gas-tight seal in a single rigless wireline run, eliminating the need for section milling and casing removal. Targeted at oil & gas operators needing P&A operations.
• Master Surface Annulus Safety Valve (MSAS™) Fail-safe close hydraulically operated barrier valve installed in the VR profile at wellhead side outlets, providing independent double barrier integrity and mitigating risk of uncontrolled annular release. For oil & gas operators managing sustained annulus pressure.
• VR Sense™ Annular Monitoring System Wireless continuous real-time annulus pressure and temperature monitoring system with dual independent metal-to-metal barriers at the wellhead VR profile. For operators requiring long-term well integrity verification.
• A-PRO™ Annulus Pressure Management System

Quantifiable outcome

• Reduced rig time by avoiding additional deep-set bridge plug installations
