Tubing Check Procedures

Example Well Parameters

Tubing Leak ProcedureDry Gulch ResourcesFantasy Land #A-1

The following procedure represents the fundamental steps needed to accomplish most tubing check applications. However, due to the investigative nature of production logging, it must be noted that the following procedure may be modified at any point in order to optimize the definition of events or abnormalities. This procedure should be considered as a general plan of action.

1. Conduct safety meeting to identify location hazards, review well information, review test objectives, and make necessary plans to maximize safety and test results. Contact Henry Hammer at 555-555-5555 or Burl Wylie at 713-256-3962 if any more information is needed.

2. Be sure to check that the tubing has been shut-in and pressure is being bled off of the tubing annulus.

3. Rig up slickline unit on Fantasy Land #A-1. Pressure test lubricator and surface configuration as per Dry Gulch Resources specifications.

4. Attach Slicklogger encoder head and depth interface unit to slickline unit assembly.

5. Attach logging tool dummy bars, 15' of 1.375" O.D. or 1.5" O.D. bars and a 2" O.D. gauge ring, to the slickline.

6. Run in hole with dummy string to 9,500', flag wireline depth, and report any tight spots to Madden Systems' representative.

7. Pull out of hole with dummy string.

8. Attach Slicklogger memory tool string to slickline. The Slicklogger memory tool contains a Capacitance, Scintillation Gamma Ray Detector, Temperature, CCL, and Pressure sensors. These sensors are contained in a 15' 9" by 1.375" O.D. housing. There will also be a 2" O.D. Continuous Flow Meter (Spinner) attached to the tool. (Flow meter size may be adjusted with the results of the dummy run.)

9. Install lubricator and pressure test for leaks as per Dry Gulch Resources specifications.

10. Check tubing and casing pressures to be sure the casing pressure has dropped enough to begin logging passes.

11. RIH with Slicklogger memory tool into the tubing at approximately 60 feet per minute to 100' WL.

12. Record tubing and casing surface pressure.

13. Make a logging pass from 100'(WL) to 9,500'(WL) at 60 feet per minute.

14. Make a logging pass from 9,500'(WL) to 100'(WL) at 60 feet per minute.

15. Land Slicklogger tool and bleed pressure from the lubricator.

16. Retrieve, download, and process data form Slicklogger tool.

17. Rig down equipment and return well to production status.

18. Contact the Dry Gulch Resources field representative to give preliminary results and the current status of Land #A-1.

8. Install lubricator and pressure test for leaks as per Dry Gulch Resources specifications.

9. Check flow rates and pressures for stable flow conditions prior to making logging passes.

10. RIH with Slicklogger memory tool into the tubing at approximately 60 feet per minute to 100' WL.

11. Record tubing and casing surface pressure.

12. Make a logging pass from 100'(WL) to 9,500'(WL) at 100 feet per minute.

13. Make a logging pass from 9,500'(WL) to 100'(WL) at 100 feet per minute.
