Core offering

Gunnar Energy Services delivers specialist active magnetic ranging and wellbore intercept services for the oil & gas and energy transition industries. Using a proprietary portfolio of hardware sensors (DeadAhead™, DeadSet™, CTRWD™, Torped™, EverReady™, MaxWell™) integrated with the AI-powered TopGun™ interpretation platform, the company locates and intersects target wellbores with inch-level accuracy at distances far beyond conventional ranging limits. Services span relief well drilling and blowout intercept, complex plug & abandonment (P&A), CCUS well integrity, geothermal closed-loop placement, solution mining connections, well re-entry and milling, SAGD/CSG twinning, and municipal water/civil infrastructure — delivered end-to-end by one accountable team covering engineering, ranging, drilling, milling and kill.

Product overview

Gunnar Energy Services offers a unified portfolio of active magnetic ranging and wellbore intercept services, combining proprietary hardware and AI-powered software into a single accountable team for engineering, ranging, drilling, milling and kill operations. The core technology stack comprises DeadAhead™ (wired-pipe AMR-While-Drilling), DeadSet™ (wireline AMR), CTRWD™ (coiled-tubing ranging), Torped™ (at-bit magnetic source), and EverReady™ (passive ranging), all unified by TopGun™ AI software for automated analysis and decision support, with CleanCut™ for precision milling simulation and MaxWell™ for casing magnetization enhancement. Services span relief well and blowout intercept, plug and abandonment, CCUS well integrity, geothermal placement, solution mining, well re-entry and milling, SAGD/CSG twinning, and water/civil infrastructure.

Products and services

• DeadAhead™ AMR-While-Drilling Wired drillpipe active magnetic ranging-while-drilling system delivering continuous ranging from the BHA with up to 500 ft range, ~8-minute survey at each station, and ~10× the current injection of traditional wireline ranging (50A). Eliminates re-entry wireline runs for relief wells, P&A, and blowout intercept. U.S. Patent 11,781,421 B2.
• DeadSet™ Wireline AMR MEMS/solid-state wireline active magnetic ranging system with interchangeable sensor packages and optional gyro module. 200 ft range, ±5% distance accuracy, ±3° direction accuracy, designed for first-attempt intersection of relief wells and complex P&A targets.
• CTRWD™ Coiled-Tubing Ranging Active magnetic ranging inside a pressure-contained coiled-tubing bottom-hole assembly for live-well intercept operations under pressure. Up to 300 ft range, ~2× wireline current injection, with a 3.5 inch tool for narrow and deep tubulars.
• Torped™ At-Bit Magnetic Source Rotating-magnet magnetic source at the bit, detected by a receiver in the offset well. Up to 330 ft range, vendor-neutral and deployable in virtually any BHA, with optional gyro module for vertical intercepts. Best for twinning, intersection and avoidance applications.
• EverReady™ Passive Ranging No-access passive ranging from existing MWD/GWD steering data, processed remotely with AI-driven interpretation and proprietary interference processing. ±5% distance accuracy, ±3° direction accuracy; detection range typically >30 ft; no extra tools or re-entry required.
• TopGun™ AI Interpretation Software Web-based AI suite for automated ranging analysis, 3D visualization, and real-time decision support, with a GPT-driven interpretation layer that connects all Gunnar ranging methods into a single end-to-end cycle; described as the industry's only commercial end-to-end ranging software.
• CleanCut™ Milling Simulation Precision milling simulation that converts intercept geometry into real-world milling parameters, reducing rig time and operational risk at the contact point during intercept-and-mill operations.
• MaxWell™ Casing Magnetization Casing magnetization service that strengthens passive ranging signal up to 2× by aligning magnetic domains and removing manufacturing inconsistency; effect is durable and lasts years across multiple operations. Available as an add-on module to other ranging services.
• Relief Well & Blowout Intercept Service Deterministic intercept and kill of wild wells when surface control has failed. Includes 24/7 emergency response, relief well planning, ranging, drilling, dynamic kill, and regulator-witnessed permanent abandonment. Used to kill an 8,000+ bbl/day blowout in under a week (Permian Basin 2026 case study).
• Plug & Abandonment (P&A) Service No-access ranging and outside-in milling for permanent sealing of complex and legacy wells with damaged casing, stuck packers, or lost surface access. Delivers up to 50% rig-time reduction versus conventional wireline P&A.
• CCUS Well Integrity Service Wellbore placement and integrity assurance for carbon capture, utilization and storage operators, including legacy well sealing at storage sites, injection well placement, and monitoring well positioning to support MRV and CO2 storage permit compliance.
• Geothermal Well Placement Service Precise intersection and closed-loop connection services for next-generation geothermal projects, including well twinning and multi-well spacing for heat zone access. Validated by world's first dual ~29,500 ft geothermal intercepts in Bavaria 2024.
• Solution Mining Connections Service Wellbore intercept for potash, lithium and uranium recovery operations, providing controlled geometry for injection/recovery well connection, cavern spacing, and field-wide spacing consistency for solution mining designs.
• Well Re-Entry & Milling Service Outside-in milling and re-entry of damaged casing, stuck packers, fish, and high-angle wells with lost surface access. Uses ranging-driven bypass paths to re-enter blocked wells that cannot be addressed with conventional re-entry.
• SAGD & CSG Twinning Service Precise well twinning, spacing and intercept for SAGD and coal seam gas producers addressing MWD survey error on multi-pad developments. Provides toe-to-toe intercepts for hydraulic communication between injector/producer pairs and anti-collision scans.
• Water & Civil Infrastructure Service Horizontal water well drains, satellite well interception, river crossings via horizontal directional drilling (HDD), and cased-target ranging for municipal water suppliers and civil infrastructure projects. Demonstrated up to 100× aquifer exposure vs. vertical water wells and ~12× restored water output in Oklahoma pilot.
