Title:
DOWN-HOLE VIBRATIONAL OSCILLATOR
Document Type and Number:
WIPO Patent Application WO/2016/090209
Kind Code:
A3
Abstract:
The invention discloses a set of valves that impart hydraulic pressure pulses at specific frequencies that provide oscillatory movement of a shuttle valve within a of a downhole tool operations. These vibrations can lead to pulses for vertical seismic profiling of formations drilled, to check the location of the bit, or to detect the presence of abnormal pore pressure ahead of the bit. The pressure pulses can also be used to enhance drilling and production of wells.
