Overshots

A small, rugged tool designed for engaging and retrieving sucker rods, couplings, and other items from inside tubing strings. The Logan Series 10 Sucker Rod Overshot consists of a Top Sub, Bowl, Grapple, and a Guide. Depending on the diameter of the fish, either a Spiral or Basket Grapple will be used. Fish diameters near the maximum catch limits require the use of a Spiral Grapple and a Control Guide. Fish diameters that are substantially below the maximum catch limits of the Overshot require a Basket Grapple, a Basket Grapple Control, and a Plain Guide.

The Logan Series 150 releasing and circulating overshot consists of three main external parts: a top sub, a bowl, and a guide. Internal catch and pack-off parts are determined by the diameter of the fish. Each Series 150 Overshot assembly is designed for a maximum catch diameter. A Spiral Grapple, Spiral Grapple Control, and a Type A Packer are used in the overshot bowl when the diameter of the fish is near the published maximum catch diameter of the overshot. When the diameter of the fish is considerably below the maximum catch diameter of the overshot (usually 1/2”), a Basket Grapple, a Mill Control Packer, or Basket Grapple Control are used in the overshot bowl. The Series 150 Special allows the fishing of 4” ESP in 5.5 casing with a minimized risk of bowl damage and a cut lipped guide for easier fishability.

Designed for conditions when the fish is too short to be engaged with a standard overshot. The Grapple Control is positioned above the Basket Grapple rather than below it to allow the Basket Grapple to occupy the lowest position in the Bowl. This enables the overshot to firmly engage and retrieve a very short fish. The Logan Series 70 Short Catch Overshot assembly consists of a Top Sub, Bowl, Basket Grapple Control, and a Basket Grapple. Although the Series 70 Overshot has no Guide, the components function in the same manner as the standard Logan Series 150 Releasing and Circulating Overshot.

Designed for conditions when sucker rods, couplings, and other portions of a fish are too short for retrieval with a standard overshot. The Logan Series 20 Sucker Rod Overshot consists of a Top Sub, Bowl, Basket Grapple Control, and a Basket Grapple. The Grapple Control is located at the top end of the tool between the Top Sub and the Basket Grapple. The position of the Grapple Control above the Basket Grapple rather than below it allows the Basket Grapple to occupy the lowest position in the Bowl. This permits the exposed part of the fish to enter the Basket Grapple where it can be firmly and securely grasped.

The Logan Series 160 Side Door Overshot is recommended when fishing for cable tools or conductor lines in cased holes. The side door overshot is run in on tubing or drill pipe. Line can be fed into the tool by removing the door on the side of the bowl. The door is put back into position after the line is in place. The feature eliminates the necessity of cutting the line or cable and the possibility of the lines fouling when there are two lines in the hole.

The Logan Hydraulic Release Overshot is designed to aid in the recovery of a stuck fish in a horizontal drilling application where normal rotation for release is not obtainable. The tool is manufactured of the finest available alloy steels and to the precise tolerances that have become a Logan standard.
