UltraJar
Denali Energy Services presents UltraJar — the Ultimate Double Acting Hydraulic Drilling Jar engineered for wells where conventional jarring solutions fall short. Designed specifically for highly deviated, high-friction, and extreme-temperature environments, UltraJar delivers bi-directional impact force with full rigfloor control and no latch mechanism required.
Built for consistency and operator confidence, UltraJar maintains hydraulic delay in both directions across the full operating temperature range, with seals rated to 200°C / 400°F standard and options extending to 230°C / 450°F for extreme hot hole conditions. Advanced Tungsten Carbide coatings, full bore internal diameter, and a fully customizable connection interface make UltraJar a reliable, high-performance solution for the most demanding downhole conditions.
Features and Benefits
Dual Direction Impacts:
Maintaining hydraulic delay in both directions ensures consistent jarring performance and maximal impact when firing up or down.
Controlled Force Application:
Driller retains full control of all aspects of the jar firing.
Consistent Delay Times:
Multi-Environment Reliability:
Regardless of well profile or bore condition UltraJar overcomes obstacles that could hinder the application of ample force to release a mechanical latch.
Torque Independence: Operated by simple up and down motion with no requirement for applied torque.
High Temperature Standard:
160 ºC/ 340 ºF seals standard in all UltraJar tools with option to extend operating range to 200 ºC / 400 ºF for hot hole or 230 ºC / 450 ºF for extreme hot hole.
Full Bore Internal Diameter:
Allows for unobstructed passage of balls, darts or wireline, while minimizing pressure loss.
Enhanced Corrosion Resistance:
Advanced engineering and specialized Tungsten Carbide coatings prevent wear and ensure sealing surface performance.
Safe Surface Handling:
Safety clamp maintains UltraJar fully extended removing any possibility of accidental firing.
Extended Operating Envelope:
Advanced engineering and superior sealing technology ensures reliable and efficient performance, allowing continued jar impacts without compromising effectiveness.
UltraAccelerator Partnership:
Ideally run with Black Diamond’s UltraAccelerator to maximize impact and protect surface equipment.
Fully Customizable:
UltraJar can be manufactured with any drill pipe connection type
