Description of the Material: Presentation of sonic energy principals, spectral analysis measurements of stuck tubulars, data interpretation, equipment description, case histories.
Application: Technique for extracting stuck tubulars during drilling, completions and work-over operations using Resonant Vibratory Techniques via surface equipment only. Can also be used in primary cement operations to maintain cement column annular hydrostatic pressure throughout curing as well as for gravel packing operations by compacting the gravel pack.
Results and Observations: This presentation focuses on the extraction of stuck oil field tubulars using Forced Oscillatory Motion tuned to Resonance of the stuck tubular system. This results in sufficient energy transferred down-hole necessary for the extraction of stuck tubulars with only surface preparations, i.e. no tripping of pipe to install down-hole equipment. The carrier fundamental driving frequency contains multiple harmonics which could also be applied to other application areas such as cement enhancement to prevent annular gas flow, or compaction of gravel during gravel packing operations. Stuck drill pipe to over 18,00' have been recovered within hours even after 24 to 48 hours of jarring operations.
Significance of Subject Matter: This technology would lower the financial losses while drilling, completing or working over wells due to lost time while trying to unstick tubing, drill pipe, liners or casing. The advantage of this technique is that only surface preparations are necessary, i.e. no down-hole tripping of pipe is required to attach tools to the work string. Rig up usually requires about 1 hour before resonant vibration commences. Fish recovery can last between under 1 hour to a few hours, depending on the borehole geometry, fish type, retaining media/mechanics, etc.
