BICO Drilling Jars are an extremely cost effective
tool that can free stuck drill strings and therefore
eliminate expensive fishing operations in many applications.
Durable by design, BICO Drilling Jars provide outstanding
performance features that insure speed and ease of operation.
Our mechanical latch does away with the need to open
the jar before running in the hole and effectively eliminates
unexpected firing while tripping in and out of the hole.
An axial visco jet provides consistent hydraulic delays
by compensating for hydraulic fluid viscosity changes
caused by temperature variance. Our rugged spline system
is built tough for reliable power transfer. BICO Jars
can be run in tension or compression within the limits
of the latch release setting.
Available in a varierty of sizes, BICO Hevi - Hitter (Dual) Hydromechanical Drilling Jars truly are cost effective for all drilling programs and can be manufactured to meet specific Client requirement.
