LockJar® Multi-Conductor E-Line Hydraulic Jar

Simple, effective device for freeing a stuck tool string during openhole logging

Halliburton’s LockJar® Multi-Conductor E-Line Jar and Enhancer provide a simple way to help avoid time-consuming and expensive stuck strings and fishing jobs in wireline logging operations.

Available in 3.5-in. and 2.75-in. OD, the LockJar hydraulic jar can be activated multiple times in multiple intervals to free a stuck tool string and preserve a logging run without costly delays.

Rated as high as 500°F (260°C) and 30,000 psi (207 MPa), the versatile LockJar hydraulic jar uses hydraulic time delay that overcomes the limitations of mechanical tools to maximize available force through surface pull.
