Tesco Casing Running Tools
Reverse designed with safety in mind, Premiere’s casing running tool (PRT™) is the result of cutting edge engineering and field tested standards.
Tool, where applicable, updated in accordance with governing API standards The CRT-350 and CRT-500 (Casing Running Tool) introduces a step change in the way casing is run today on land rigs and smaller offshore drilling facilities. By combining the functionality of field proven tools such as the Top Drive, Flush Mounted Spider (FMS), Fill and Circulation Tool and Single Joint Elevator (SJH), casing operations are now safer, faster and more efficient.

The CRT, connected directly to the top drive main shaft, hoists and lowers casing, spins in and makes up the casing connection. Additionally, while reciprocating and rotating the casing string, the CRT has the ability to fill-up and circulate up to 5,000 psi. Safety: Eliminates stabbing-board operations (reduces #1 cause of lost time while running casing); less manual handling equates to fewer safety hazards.
Power casing tong operations have been removed, allowing more work space around the well center. Eliminates drill floor work platforms. Economics: Drilling contractors, or a reduced casing crew can run the casing, minimizing stand-by costs associated with weather or problematic well conditions.

The CRT integral compensator substantially reduces the risk of damage due to cross-threading. Utilizing the top drive to control make-up reduces thread damage during the complete make-up cycle Well Improvements: Assures that the casing can be set to the casing point with the ability of the CRT to fill, circulate, rotate, and reciprocate. Reduces the risk of differential wall sticking. Includes ability to pressure test. Efficiency: Less equipment to rig up; the CRT contains the elevator, fill-up and circulating tool, and compensator in one assembly. The operator determines and controls the running/tripping speed.
When running mixed strings, hardware components can be changed within minutes through the twist lock design and insert carrier/slip design. CRT Compensator:.
