1)Packers
Packer is a key piece of downhole equipment in many completions – a sealing device that isolates and contains produced fluids and pressures within the tubing string; it is a well barrier element, usually part of the well’s primary well barrier, protecting the casing and creating an A-annulus. The packer is essential to the basic functioning of most wells, injectors or producers. Alternatives to using a production packer include a dynamic seal assembly, a cemented completion and a packerless completion.
Permanent Packer
Permanent packers can be removed from the wellbore only by milling. The permanent packer is fairly simple and generally offers higher performance in both temperature and pressure ratings than does the retrievable packer. In most instances, it has a smaller outside diameter (OD), offering greater running clearance inside the casing string than do retrievable packers.
Retrievable Packer
The retrievable packer can be very basic for low pressure/low temperature (LP/LT) applications or very complex in high pressure/high temperature (HP/HT) applications. Because of this design complexity in high-end tools, a retrievable packer offering performance levels similar to those of a permanent packer will invariably cost more. However, the ease of removing the packer from the wellbore as well as features, such as reset ability and being able to reuse the packer often, may outweigh the added cost
ESP Packer
The ESP Packer Type Gas Separator breaks down gas slugs separating gas into the annulus, before reaching the pump intake. An encapsulated shroud prevents the fluid from entering the pump intake and forces it through the separator.
2) Sub-Surface Flow Control System
Flow control system allows the operator control of the well throughout the life of the well. For examples Landing Nipples are strategically placed in the completion string (production tubing) to allow for well testing and or intervention to be carried out safely. Ragtos offers a full range of plugs and sliding sleeve made from various materials and elastomers of operator’s choice.

– Lock Mandrel
– Sliding Sleeve
– Blanking plugs
3) Sub-Surface Safety System
Surface Controlled Sub-surface valve (SCSSV) is the first line of defense against well blow up. The fail safe system built into the valve is subjected to stringent rigorous testing and the intricate yet robust component will ensure no compromise to safe operation.
Open hole packers
Openhole packers have been shown to be very effective in many different applications, including curing losses, controlling high-permeability zones and fractures, improving equalization in passive- and active-inflow-control-device (ICD) completions, and, most importantly, controlling water and gas production. The use of these tools has increased exponentially in the last few years and will continue to grow.
