Hydra-Jar AP Total impact control for operational flexibility
Complete directional control of impact force The Hydra-Jar AP double-acting hydraulic drilling jar amplifies the force applied at surface in order to free stuck drillstring components during drilling or workover operations. It also offers the driller an important control option: to jar up, or down, with a force ranging from a light blow to an extra-heavy impact.
Applications ■
drilling or workover operations
■
HPHT drilling conditions
In most applications, the tool should be run in conjunction with the Accelerator AP* impact tool to incre increase ase impact impact while protect protecting ing the the drillstri drillstring ng and surfac surface e equipment equipment from shock. shock.
Rugged durability ensures performance The Hydra-Jar AP* is balanced to hydrostatic pressure through ports open to the wellbore, ensuring consistent hitting performance regardless of changes in downhole pressure. This consistent hitting performance is further ensured by the jar’s detent system: it provides more consistent loading and firing of the jar over a broad range of borehole temperatures. The jar’s unique metering process compensates for the decrease in detent cylinder oil viscosity as the jar is fired repeatedly, ensuring consistent impact regardless of downhole conditions. And, the Hydra-Jar AP jar’s highly durable seals make it the best choice for high-pressure, high-temperature (HPHT) drilling conditions. These features—combined with careful materials selection and field-proven engineering—deliver a uniquely rugged, reliable downhole impact system.
Flexibility for all drilling environments The Hydra-Jar AP drilling jar performs effectively in every drilling environment—land or offshore, vertical or deviated wells, and ultradeep or ultrahot boreholes. Because the system works without applied torque, directional drilling tools maintain their orientation throughout through out the jarri jarring ng operation operation.. The jar may may be run in in compressi compression on or tensio tension, n, enabling enabling optimized placement in the drillstring.
Effective and efficient for operational viability The Hydra-Jar AP jar’s fullbore design minimizes pressure losses and provides wireline tool compatibility. The jar makes up, racks, and handles like a standardlength drillpipe, reducing trip time. It provides up, down, or up-and-down impact without torquing or tripping for adjustments. And, the Hydra-Jar AP jar expands options for drilling, coring, cementing, testing, fishing, workover, and remedial operations.
