The Extraction of Mud-Stuck Tubulars Using Vibratory Resonant Techniques

Abstract

fax 01-972-952-9435. AbstractStuck pipe has been identified as the largest single contributor to non-productive drilling time. The use of resonant vibration as a means of freeing stuck tubulars from a well bore has been demonstrated to be effective in both Drilling and Workover environments and has the potential to provide almost immediate results in many day-to-day applications. The challenge for the future is to further explore both proven and potential applications of this technology in order to evaluate the benefits and reduce the unknown associated with the technology. The long term industry benefit will be a new approach to stuck tubular recovery available in the form of superior technology that addresses real needs while substantially reducing costs. The technology offers the benefits of being quick and easy to apply, operations are conducted from surface with no downhole intervention, and results may be achieved very quickly. Good success in open hole work could mean that this technology could become the procedure of choice in virtually all drilling operations. In workover operations, the technology may accomplish the same results in hours that typically require days by current standards.

Stuck Coiled-Tubing Recovery Utilizing Surface Equipment and Methods

“…The theory behind the use of Surface Resonant pipe extraction has been well documented in literature 4,5 . The advantages of using vibration for coil tubing extraction aren't so obvious but can be itemized as:…”
