Drilling, Milling and Cutting Tools
Welded Cup Junk Subs
The Logan Welded Cup Junk Sub is an accessory tool that prevents cuttings from milling or drilling operations that are too heavy to be circulated from settling at the bottom of the hole.
Threaded Junk Subs
The Logan Threaded Cup Junk Sub is an accessory tool that prevents cuttings from milling or drilling operations that are too heavy to be circulated from settling at the bottom of the hole.
Logan Crossover Subs provide safe connection between joints of different sizes or types of drilling, tubing, or washover string sections having different end connections.
The Drop Ball Circulating Sub is designed to run immediately above or below the BHA. Activation is accomplished by dropping the S.S. Ball from the surface and applying pump pressure.
The Logan T-Dog Overshot is designed to catch collared pipe or tubing and is releasable.
Standard External Cutters
The automatic spring-fed knives feature of this tool prevents excessive strain from being applied from the rig floor that could cause the knives to burn or break before the cut is completed.
Hydraulic External Cutters
These quick, smooth operating tools allow for fast recovery of tubing or drill pipe. A hydraulically fed piston forces the knives of this cutter into the pipe to give the operator sensitive cutting control.
Logan Internal Cutters are used to cut tubing, casing, and drill pipe and may also be run on sucker rods and macaroni strings.
Internal Pressure Pipe Cutters
The Logan Internal Pressure Pipe Cutter utilizes pump pressure to actuate three carbide-coated knives to cut single and multiple strings of pipe from 4 inches O.D. to 36-inches O.D.
