High-Impact Drilling Jars

Calibrated downhole contingency tools engineered to deliver massive upward and downward impact forces, freeing stuck pipe in high-temperature, high-pressure environments.

Mechanical Limits

Engineered for 400°F HTHP Wells

Every Thermotics jar is built with specialized sealing arrays and high-tensile alloy steel to survive extreme thermal stress and continuous high-torque operations.

Thermal Threshold

Bi-Directional Impact

Torsional Integrity

Rated up to 400°F (204°C) continuous downhole temperature with custom Viton and PTFE sealing stacks.

Fully independent hydraulic delay for upward jarring, with a robust mechanical latch for positive downward trip force.

High-torque spline design ensures full torque transmission through the tool string during aggressive rotary drilling.

Custom Impact Calibration

We do not just ship steel. Every drilling jar configuration is pre-calibrated to your specific wellbore friction coefficients, drag profiles, and BHA weight.

Predictive Modeling

Using advanced software, our engineering team models your drill string's exact mechanical behavior to determine optimal jar placement. This ensures maximum impact force is delivered directly to the stuck point without exceeding tool yield limits.

Operational Verification

Post-run inspection reports and drag calculations verify that the tool performed within its calibrated envelope, providing critical data for subsequent well intervals.
