VIBRATION TECHNOLOGY WORKOVER

Any situation where the axial reciprocation of pipe or the use of large tensile, compressive, or percussive forces or where the reduction of pipe to wellbore friction is beneficial may respond favorably to the use of pipe vibration. The process is applied from surface, generally without any downhole intervention, and often provides immediate results. Pipe vibration is generated and applied at surface and transmitted by the free portion of the pipe string to the stuck point that may be thousands of feet below. The results are quick release from sand or junk stuck situations. Rig-up time is usually less than an hour and results are often achieved in minutes. On a recent job, a string of 2-7/8" EUE tubing, tubing anchor, and sand stuck sucker rods inside were recovered simultaneously thus avoiding an outside backoff attempt with the real potential of leaving the rod string standing inside the well casing. In other typical jobs, wirewrap screens and packers are recovered from gravel pack completions, totally avoiding jarring and washover operations.

On another recent job, recovering a 10,000 foot scale stuck rod string, a combination string of 7/8" and 3/4" sucker rods was recovered thus avoiding a tedious and often time consuming stripping job with associated risks as well as the potential for considerable rod damage.

Vibration Technology provides equipment and services that are highly effective in recovering stuck pipe in a range of applications including mud, scale, salt, sand, or junk stuck downhole equipment such as:

• Insert Pumps
• Submersible Pumps
• Rods
• Tubing Anchors
• Tubing
• Liners
• Gravel Pack Screens and Packers
• Retrievable Packers
• Bridge Plugs
• Bottom Hole Assemblies
