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

The 4 1/2" Surface-Controlled Subsurface Safety Valve (SCSSSV) is selected for wells that require dependable emergency shut-in capability while handling moderate to high flow rates. This size is appropriate when production demands a larger flow area to minimize pressure drop and maintain efficient fluid flow. It provides essential well control by automatically isolating the wellbore in cases of equipment failure or loss of surface control pressure, ensuring safety without compromising production efficiency.

This SCSSSV is designed for compatibility with 4 1/2" (114.3 mm) tubing and is available with landing nipple seal bores of 3.437", 3.688", or 3.813". It supports working pressures up to 5,000 psi and comes with internal valve bore options of 1.75", 1.87", and 2.12"—allowing operators to balance flow capacity with safety requirements.

The self-equalizing mechanism minimizes differential pressure across the valve during opening, improving control and reducing mechanical wear. With sealing surfaces located outside the flow path in the open position, the valve is less susceptible to erosion and damage during production.

Constructed with a robust flapper made from bar stock, the valve features a flapper-type mechanism that reliably closes to prevent uncontrolled flow. The valve is wireline retrievable, which allows for extraction and servicing of major components without removing the entire tubing string. This capability reduces intervention time and operational costs, contributing to overall well uptime and efficiency.

The 2” Tubing End Locator is a mechanical downhole tool used to determine the physical end of production tubing during well intervention or maintenance activities. It is a critical component in operations where it is necessary to confirm tubing length or avoid tool deployment beyond the tubing’s bottom, such as during setting packers, logging, or fishing operations.

In a typical well setup, production tubing does not always terminate at a predictable or recorded depth. The tubing end locator provides a reliable way to identify the true end of the tubing string by using a spring-loaded finger mechanism that reacts upon reaching the tubing’s bottom. This reaction is detectable at the surface, providing the operator with a clear and immediate indication without relying solely on depth readings or assumptions.

This specific model is intended for tubing sizes ranging from 2" to 2-1/2" outer diameter. It is designed with a maximum tool O.D. of 1.750", which ensures clearance inside the tubing, and includes a 1.375" fishing neck, a standardized feature that allows the tool to be retrieved if necessary using conventional pulling tools.

Threading is provided on both ends for integration into tool strings: a 15/16 - 10 UN pin connection on top and a 1 - 11.1/2 NPT box connection at the bottom. This allows the locator to be run inline with other mechanical or wireline-conveyed tools. These standard thread forms ensure compatibility with widely used downhole equipment and deployment systems.

Constructed from high-strength alloy steel, the tool is designed to withstand the mechanical stress, temperature variations, and chemical exposure typical in oil and gas well environments. While not a pressure-control device, its materials and design are selected to perform reliably under downhole pressure conditions encountered during standard intervention work.

The 2” Tubing End Locator provides a mechanical means of depth verification that does not rely on electronics, sensors, or depth counters. It is a simple, durable, and effective tool for reducing uncertainty and improving operational safety in the wellbore.
