The Floating Drift Will Drift The Pipe After The Connection Is Torqued Up On Surface AND Does Not Add Any Additional Time to Running Tubulars. If The Connection Is Over Torqued, The Problem Is Caught At The Surface And Pulled Out Of The String. This Eliminates Having To Pull Completion Strings Out Of The Hole Once on Bottom.
Convntional Ways To Drift Pipe
Dropping a Hollow Steel Drift with a wireline tail on it.
- The method only drifts pipe that is being pulled out of hole and does not ensure that the pipe is free from debris from the pin board or crimped/crushed during makeup.
Drifting pipe out of the Derrick.
- This method ensures the pipe is clear after setting on the pin board but does not ensure that the pipe is not damaged during makeup or setting slips. It is the most dangerous forms of drifting out of all the methods and very time consuming.
Drifting pipe out of the V-Door.
- This method cannot guarantee that the pipe is not damaged during make up it only ensures the pipe was clear and damage free prior to making the pipe up.
Floating Drift Solves And Prevents Above Problems
The Floating Drift is installed in the first stand or joint
The drift is at the bottom of the drift assembly below the connection being made up. After the connection is made up, the fluid column allows the drift to float through the pipe and all connection ensuring the pipe did not get crimped or the connection over torqued.
If the Drift Light is not seen this indicates an ID restriction immediately letting you know that the tubular needs to be pulled to find the problem.
There is the option to add a debris basket and magnets to assist with removing dope and smaller debris out of the pipe.
In short, the Floating Drift eliminates the possibility of problems with debris or ID restriction before your pipe is on bottom.
Savings Compared To Conventional Drifting
Comparing the time to drop a drift from the derrick, actual time savings have shown between 2.5-4 minutes more per stand to drift out of the derrick, while running the Floating Drift has the same trip speed as not running a drift at all.
We have also eliminated the need to run wireline gauge ring runs after running production tubing.
All tubulars run in the hole are drifted after being made up. In the event that the connection is over-torqued, The Problem will be caught at surface instead of finding out after the string is on bottom. This eliminates a costly trip out of the hole to the remove the bad joint.
The Floating Drift also catches any debris in the tubular that will prevent Electricline Tools, Slickline Tools, Balls or Darts from reaching bottom. Once again, the problem is discovered before the string is on bottom. This again eliminates a costly trip out of the hole.
The Floating Drift has also proved to catch any ovality problems on tubulars that would prevent packers and other tools from setting or being run in the pipe.
When running the Floating Drift in production Tubing, the normal slickline gauge ring that is standard protocol is eliminated since all tubing is drifted as it is run. This saves time and money.
