SAFETY VALVES
CTR Supplies a number of different models of Safety Valves like Tubing Retrievable and Wireline Retrievable Valves.
The Valves can be delivered in standard material and in High Nickel Chrome alloys like 718 and 925 Inconel.
Our Tubing Retrievable Surface Controlled Sub-Surface Safety Valve along with the 6 inch Wireline Retrievable Valve (3SV) has been tested based on API 14A requirement with well proven and successful installation track record.
CTR TRSCSSSV
The CTR's Tubing Retrievable Surface Controlled Sub Surface Safety Valve (TRSCSSSV) is piston rod activated flapper-type safety valve which is designed to shut in a well at a point below the surface.
The valve is held open by hydraulic control pressure and remains open until the control-line pressure is exhausted. The hydraulic control pressure is transmitted from a remote location through a single control line to operate the valve.
CTR also supply’s all the needed accessories to run the valves including the Control lines and control line protectors and
CTR`s own Control Line Spooling unit that has all the needed test pumps and recording devices integrated into the unit.
TRSCSSSV Features:
Optimized geometry and reliable curved flapper metal-to-metal seal.
Heavy duty double torsion spring ensures the valve closing.
Metal-to-metal static seal in the open and closed positions Wiper ring on the piston rod protects the dynamic seals.
Optimal geometry and clearance between sliding components.
Integrated lockout mechanism.
Shock absorber protects internal parts from slam closure.
Metal-to-metal flow tube seating isolate components during well production.
Available in Self Equalizing and None Equalizing types.
Inverted dual – ferrule control line connection.
Tested successfully as per industry standard.
Designed and tested in industry common sizes.

ONE RUN COMPLETION (ORC)
CTR has introduced the ORC (One Run Completion) into the market and successfully run the system in the Middle East on Gas Wells with High Flow Rate.
The ORC is a new method of completing the wells with Monobore production string, which is developed and after successful surface test installed in gas wells.
All pressure tests after installation were satisfactory.
The ORC System enables the operator to run the Liner Top Packer and the Complete Tie Back in one run, this will give a
time saving of 36 + hours when running the completion.
Also the seals on the Tie Back Seal Stem will be protected when running into the well.
ORC Features:
The seal stem is not bare while running in hole and the seals are not subject to any damage.
Extreme drag in highly deviated wells can not misguide the space out.
The ORC eliminates the requirement of repeating the space out.
There is less concern with the well safety.
It eliminates running the work string for running the packer and the well remains clean of drill pipe dope and flakes.
It saves minimum 2 days of rig time.
The System gives the operator a fixed reference point for the space out without having to stab the system in and out for finding the locator point.
TIE BACK PRODUCTION PACKER
CTR’s Tie Back Production Packer is a high performance permanent production packer covering the standard operating envelope.
The packer has successfully passed the ISO 14310 test at V0 level.
The Packer utilizes a single element and full circle hold down slips covering the variety of casing sizes.
