Surface Bumper Jars Product Link Icon

The Logan Surface Bumper Jar is used whenever the downhole drilling, fishing, or washover running string becomes stuck and requires a heavy downward force to release it. It is often used to free key seated drill pipe and drill collars, and initiate sharp jarring blows down the string to actuate drilling bumper subs, bumper safety joints, and other similar downhole bumping tools. It is also useful for transmitting heavy downward impact to release embedded grappling tools. Because it is intermittently used only on the surface to release a stuck fish, this tool has an extended service life when compared to conventional bumper subs.

The Logan Lubricated Fishing Bumper Sub is a dependable accessory that is suitable for all fishing operations, especially harsh, downhole applications, and deep workover operations. It can also meet the demands of tools that require sharp, sustained bumping action to actuate or release them. The tool enables the operator to release the fishing tool in the event it becomes impossible to pull the fish. It can provide the necessary impact in either direction and deliver the required torque.
