The Alligator Grab is a wireline fishing tool used to catch and retrieve loose or broken objects from inside an oil or gas wellbore. It has spring-loaded, serrated jaws that can be adjusted before use to set the right amount of grip for the object being retrieved. When downward force is applied, a pin shears, allowing the jaws to close and hold the object securely.

This tool is needed when small or hard-to-reach objects, often called “fish,” are stuck or floating in the wellbore. Unlike other retrieval tools, the Alligator Grab provides a controlled grip that can be adjusted to the size and type of object, reducing the risk of pushing it further down or damaging the well. It is not meant for heavy jarring once it has gripped an object, so it is used for careful and precise recovery.

The Alligator Grab comes in various sizes, with a maximum outside diameter of 1.25 to 3.50 inches, a fishing neck O.D. of 1.187 to 2.313 inches, and top connections ranging from 15/16-10 UN to 1-9/16-10 UN. It includes fishing necks and pin threads compatible with standard wireline equipment.

What makes this type of Alligator Grab unique is its ability to retrieve objects in tight or restricted wellbore spaces. Its adjustable jaws and compact size allow it to securely grip objects that other tools might not reach, making it especially valuable for precise and reliable recovery operations.

The 2 9/16” 5M Coiled Tubing Hanger is a tool designed to securely hold coiled tubing in place during well operations where pressure can be high—up to 5,000 psi. It is built to support heavy coiled tubing and the equipment attached to it when performing tasks deep inside the well.

This hanger works with coiled tubing sizes of 1 inch, 1¼ inches, 1½ inches, and 1¾ inches in outside diameter, making it suitable for a range of tubing types used in different well operations. It connects to the wellhead using standard flanged connections.

A special feature of this hanger is its wireline entry sub. This part acts as an extra seal around the tubing to maintain pressure control in the well while allowing wireline tools to pass safely through the tubing. The wireline entry also prevents the tubing from moving upwards during operations, which helps protect the equipment and maintain well safety.

The hanger is powered by electricity, which supports reliable operation in the field. Overall, the 2 9/16” 5M Coiled Tubing Hanger helps keep the tubing stable, maintain well pressure, and allow tool access during important tasks like cleaning the well, stimulating production, or running diagnostic tools.

Available sizes: 2 3/8”, 2 7/8”, 3 1/2”, 4”, 4 1/2”, 5”, 5 1/2'” and 7”.

The 4-inch Surface-Controlled Subsurface Safety Valve (SCSSV) is designed for installation in wells with 4-inch production tubing and serves as a critical safety device to shut in the well during uncontrolled flow events caused by equipment failure or loss of surface hydraulic control pressure. The valve operates via a hydraulically actuated flapper mechanism that remains open under normal operating pressure but closes automatically if the hydraulic signal is lost. This fail-safe design isolates the wellbore, preventing unintended release of hydrocarbons and protecting both personnel and the environment.

The flapper mechanism is simple and robust, minimizing moving parts in the flow path and reducing potential points of failure. When open, the sealing surfaces are positioned out of the fluid flow path, which helps maintain smooth production flow and reduces wear on sealing components. The valve’s hydraulic actuation allows reliable operation under varying pressure and flow conditions commonly encountered in oil and gas wells.

The valve is wireline retrievable, which means it can be removed, serviced, or replaced using wireline tools without the need to pull the entire tubing string from the well. This capability significantly reduces well intervention time and associated costs while allowing maintenance or upgrades to be performed efficiently.

This SCSSV fits standard landing nipples with a seal bore of 3.313 inches and is rated for working pressures up to 5,000 psi. Its internal valve diameter is 1.75 inches, providing an appropriate balance between flow capacity and structural integrity for wells with moderate to high flow rates. The 4-inch tubing size is common in many oil and gas production wells, making this valve size versatile across different field conditions.

This size is commonly applied in production wells where 4-inch tubing is standard, supporting reliable well control and efficient maintenance. Its hydraulic surface control and simple flapper design contribute to dependable operation under varying well conditions.

The 3” Tubing End Locator is a mechanical downhole tool used to identify the precise end of a 3-inch production tubing string during well intervention operations. It provides a clear physical indication when the tool reaches the bottom of the tubing, helping to ensure accurate placement of equipment inside the well.

Designed specifically for tubing with a 3-inch outer diameter, the tool features a maximum outside diameter of 2.500 inches. This sizing ensures smooth movement within the tubing while maintaining close contact, allowing the tool to operate effectively without the risk of sticking or misalignment. At the core of the design is a spring-loaded finger mechanism that extends outward when the tubing end is reached. This mechanical movement is transmitted to the surface as a tactile response, signaling that the tubing bottom has been contacted.

The tool includes standard threaded connections—such as a 15/16 - 10 UN pin on the top and a 1 - 11 ½ NPT box on the bottom—which makes it compatible with a variety of toolstring configurations. It can be easily incorporated into slickline, wireline, or coiled tubing assemblies without the need for special adapters.

Constructed from durable, corrosion-resistant materials, the tubing end locator is built to perform reliably in downhole environments that involve high pressure, elevated temperature, and exposure to fluids. Its fully mechanical operation ensures a high level of dependability and minimizes the need for maintenance, especially in conditions where electronic systems may not be suitable.

The 3” Tubing End Locator is a practical solution for confirming tubing depth when preparing the well for further intervention.

The 6 5/16” to 2 1/2” Tubing Hanger Coupling is a specially made part used in oil and gas wells to connect a large casing opening to smaller tubing—typically 6 5/16 inches—to a smaller 2 1/2-inch upset production tubing. This size combination is often selected for well designs that require a broader casing interface for flow management, safety equipment, or well control hardware, while maintaining a slimmer production string for specific flow requirements or structural considerations.

This coupling is manufactured with upset-end compatibility, meaning it is suited for tubing that has thickened ends designed to strengthen threaded connections. This feature improves mechanical reliability and helps the connection withstand downhole pressure, tensile loads, and thermal cycling. The union nut design allows the coupling to be installed by tightening the nut without rotating the upper wellhead assembly, which is particularly useful in space-constrained or high-integrity environments.

To accommodate a range of operational needs, the coupling can be threaded on both ends to suit different tubing or spool designs and is compatible with back pressure valves—providing added safety during pressure control, intervention, or servicing. Built in accordance with API specifications and from high-strength materials, the coupling is designed to operate reliably in demanding conditions, including high-pressure wells and corrosive environments.
