Type Z Oil Jars
Bowen ® Type Z Oil Jars
Sold Export Only
The NOV Downhole Bowen ® Type Z Oil Jar is the result of years of continuous improvement
based on actual field use. It is a straight-pull operated Jar. This Jar is simple to assemble and
easy to use. The Bowen ® Type Z Oil Jar is used for fishing, testing, coring, reaming, light
drilling, side tracking, and washover operations.
Each blow can be controlled positively by the operator to deliver a very light blow or a blow of
very heavy impact. Full circulation may be maintained throughout the tool for effective flushing.
Full torque may be utilized in either direction and is at all times by means of heavy duty spines
which are continuously in engagement.
Only straight pull is required to operate the Bowen ® Type Z Oil Jar, and successive blows can
be struck as often as the operator can slack off and raise the running string.
The Bowen ® Oil Jar should be tested in the Bowen ® Jar Tester prior to operation.
