Casing Running Tool

The introduction of the CRT-350 (Casing Running Tool) revolutionizes the way casing is run in today’s Oil & Gas Industry.

Mainly used on land rigs and smaller offshore drilling facilities, the CRT-350 combines the functionality of field proven tools such as the Top Drive, Flush Mounted Spider (FMS), Fill and Circulation Tool, and Single Joint Elevator (SJH) making operations safer, faster, and more efficient.

The CRT-350 connects directly to the Top Drive main shaft allowing for hoisting and lowing of the casing as well as connection spin in, and make-up. Additionally, while reciprocating and rotating the casing string, the CRT has the ability to fill-up and circulate up to 5,000 psi utilizing the OES proprietary Fill-up and Circulation Tool incorporated as part of the CRT-350.

Safety:

  • Eliminates stabbing-board operations which reduces the #1 cause of lost time while running casing; less manual handling equates to fewer safety related hazards
  • Power casing tong operations have been removed allowing more work space around the well center on the rig floor; eliminates drill floor work platforms

Economics:

  • Casing operations can be run with a reduced casing crew, or by the drilling contractors, minimizing stand-by cost 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
  • Ability to pressure test

Efficiency:

  • Less equipment required to rig up; the CRT contains the elevator, fill-up and circulating tool, and the compensator in one assembly
  • The operator determines and controls the running/tripping speed
  • When running mixed strings, hardware components can be changed out within minutes through the twist lock design and insert carrier/slip design
