TYPE 405 - STOP COLLAR – HINGED WITH BOLT The hinged Type 405 Stop Collar is designed to latch-on to the casing without having to be slipped over the end of the casing allowing for quick and easy installation. The holding force of the Type 405 is higher than the allowable centralizer starting force as specified in AP1 Specification 10D. It uses a nut and bolt assembly which when tightened draws the stop collar into a friction grip around the circumference of the pipe. This design does not produce markings or indentations on the casing after installation.

THE LOGAN SEGMENTED SPEAR GRAPPLE ENHANCES THE SPEAR'S USEFULNESS BY PROVIDING AN EXTENDED CATCHING RANGE BEYOND THE MAXIMUM RANGE OF THE STANDARD ONE-PIECE GRAPPLE. The segment-type spear grapple consists of a grapple body, eight grapple segments, two retainer rings, six retainer ring screws, six retainer ring spacers, and sixteen grapple segment screws.

THE RECORDER CARRIER ASSEMBLY IS DESIGNED TO CARRY PRESSURE AND TEMPERATURE RECORDERS USED TO DOCUMENT SUBSURFACE PRESSURE AND TEMPERATURE INSIDE OR OUTSIDE THE FLOW PASSAGE DURING A WELL TEST. The inside recorder slots are designed to hold the gauges which monitor the pressure and temperature of the inside flow passage during a well test. The outside recorder slots are designed to carry the gauges to record the subsurface data in one on two subsurface zones. If the carrier is run directly below the upper inflate packer, the test interval outside the flow passage is recorded. If the carrier is run above the upper inflate packer the pressures and temperatures in the annulus are recorded. Each Recorder Carrier assembly holds two inside and two outside recorders.

THE LOGAN OIL TOOLS CORE TYPE JUNK BASKET IS AN EASY TO USE JUNK RETRIEVAL TOOL DESIGNED TO EFFECTIVELY REMOVE SMALL OBJECTS SUCH AS BIT CONES, SLIPS, HAND TOOLS, AND TAIL CHAINS FROM THE HOLE. The Logan Core Type Junk Basket consists of a top sub, barrel, type A mill shoe, and an upper and lower catcher. The short fingers of the upper catcher are designed to break the core that has been cut by the mill shoe. The combination of short and long fingers of the lower catcher are designed to trap and retrieve the core and junk. Both catchers are free-revolving within the mill shoe, eliminating any breakage of the catcher fingers.

FLOAT EQUIPMENT WITH FLAPPER VALVES ARE KEY COMPONENTS FOR RUNNING CASING AND PERFORMING CEMENTING OPERATIONS. During cementing operations, float equipment is essential for preventing back-flow while also serving as a landing point for wiping and displacement plugs. When surge pressures on the formation are a concern, Top-Co brand float equipment can be configured to auto-fill to prevent formation damage. Flapper style auto-fill float equipment allows for automatic filling of fluid within the casing. Automatic filling also reduces casing running time by eliminating the need to fill from surface as well as lowering surge pressures on formations. TYPE 295/296 - ALUMINUM FLAPPER FLOAT EQUIPMENT Type 295/296 - Aluminum Flapper valve is specifically designed for use with high concentrations of lost circulation material (LCM). The open bore of the hinged flapper valve permits solids to pass through without clogging the valve. The valve is made from aluminum and is 100% PDC drillable.

EXTERNAL CASING PACKER (ECP) Continuous Mandrel ECP assemblies are designed with packer elements in 4 Foot (1.22m), 10 Foot (3.05m), and 20 Foot (6.10m) standard lengths. Rubicon packer elements soundly conform to irregular or washed-out open hole diameters. Steel reinforcement slats are used within the elements to ensure that the ECP self-centers itself in vertical, deviated, or horizontal wellbores. FEATURES The continuous one-piece mandrel eliminates the need for internal threaded connections Mandrel specifications match to the casing used in the well The Valve system is located above the packer element Valve operation is not affected by unpredictable pressure changes below the element Superior anchoring system prevents element rotation, and packer shoe travel, while tools are run into the well Rubicon ECPs can be manufactured with materials suitable for H2S and CO2 environments Shear pins in the valves may be easily adjusted in the field, allowing the operator greater flexibility when well conditions change
