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 Wireline Spear is a downhole tool used in oil and gas wells to retrieve lost, broken, or compacted wireline that cannot be engaged with a standard two-prong wireline grab. It is designed for fishing operations where the wireline has become badly balled up or tightly compacted, situations where conventional pronged grabs are ineffective.

The tool is deployed on a wireline and guided down the wellbore under its own weight. Its central mandrel is surrounded by upward-pointing barbs or slips that penetrate and anchor into the wireline. When engaged, these barbs provide a secure grip on the wire, allowing the tool and wire to be retrieved to the surface.

The Wireline Spear is designed for maximum penetration into tightly balled or compacted wire. Its barbs ensure engagement even when the wire is severely entangled. Because the Wireline Spear is effectively non-releasable, it is typically run with a disconnect arrangement above the tool. This allows the assembly to be released if the wire cannot be recovered fully, preventing the tool from becoming stuck in the wellbore.

The tool is available in sizes from 1.5” to 3.5”, with a maximum outside diameter of 1.500” to 3.500” and a fishing neck O.D. of 1.375” to 2.312”. It connects to the wireline through a top connection ranging from 15/16 – 10 UN to 1-1/16 – 10 UN and can retrieve wire diameters from 0.50” to 3.50”.

The Wireline Spear is constructed from steel to withstand downhole mechanical stresses and pressures. Its design includes a central mandrel with upward-pointing barbs that secure tightly compacted or balled-up wireline. The tool’s compact dimensions and engagement mechanism allow it to retrieve wireline that cannot be captured by standard pronged grabs, and it is generally run with a disconnect arrangement above the tool to allow release if the wire cannot be recovered.

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

The 5" SCSSSV (Surface-Controlled Subsurface Safety Valve) is used to shut in a well if there\'s a sudden loss of control—such as equipment failure or surface damage. Installed in the upper wellbore, it acts as a critical safety barrier, closing automatically if surface control pressure is lost. This helps protect people, equipment, and the reservoir from uncontrolled flow.

This valve is designed for 5" (127 mm) tubing and fits a 4.125" landing nipple. It’s rated for working pressures up to 5,000 psi and has a 2.38" internal bore, making it well-suited for high-rate production wells. The valve includes a self-equalizing feature that helps reduce pressure differences across the flapper during reopening, supporting smoother restarts and lowering mechanical stress.

Because it’s wireline-retrievable, the internal components can be serviced or replaced without pulling the tubing—saving time and reducing intervention costs. The flapper is machined from solid bar stock for durability, and the sealing surfaces are positioned out of the flow path when open, helping extend the life of the valve by reducing wear.

This size is typically chosen when both high flow capacity and reliable emergency shut-in protection are required.

In oil and gas well operations, the 2 ½” Tubing End Locator plays a critical role in confirming the exact depth at which production tubing terminates within the wellbore. Accurately identifying the tubing endpoint is essential during various well intervention activities, including maintenance, workovers, and the installation or retrieval of downhole tools and equipment.

During operations such as setting packers, deploying plugs, running logging tools, or performing fishing jobs to recover stuck equipment, precise knowledge of tubing length ensures that tools are positioned correctly. This prevents accidental over-pumping or tool deployment beyond the tubing into the open hole section of the well, where damage to equipment or tool loss can occur.

The 2 ½” Tubing End Locator is designed specifically to fit tubing with an outer diameter of approximately 2 ½ inches. It features a compact maximum outside diameter of around 1.750 inches, allowing it to pass easily within the tubing without causing obstruction. The tool employs a spring-loaded finger mechanism that activates mechanically upon reaching the tubing bottom. This signal does not rely on electronic sensors or depth measurement devices, making the tool highly reliable even in harsh downhole environments where electronics may be compromised by pressure, temperature, or fluid conditions.

Standardized threaded connections on the tool—typically a 15/16 - 10 UN pin on the top and a 1 - 11 1/2 NPT box on the bottom—enable it to be seamlessly integrated into a wide range of intervention toolstrings. These common connection types ensure compatibility with existing downhole equipment and facilitate quick assembly and deployment.

Manufactured from high-strength alloy steel or similar materials, the tubing end locator is built to withstand typical downhole conditions, including high pressure, elevated temperatures, and corrosive fluids commonly found in oil and gas wells. Its purely mechanical design minimizes maintenance requirements and reduces the risk of failure compared to electronic alternatives.

This tool is particularly valuable in wells where tubing length may have changed due to wear, repairs, or previous interventions, offering an essential measure of control and confidence in complex well environments.
