Abstract
A technique employs the use of oscillations downhole to facilitate a desired functionality of a downhole tool. According to this technique, a tool is initially conveyed downhole and operated to perform a function that relates to a downhole application. The operational efficiency of the tool is improved by creating oscillating forces which vibrate the tool to achieve a desired result, e.g. freeing the tool from a stuck position.
Claims20
A method for providing oscillations downhole, comprising:
- coupling a tool and a vibrator to a conveyance;
- moving the conveyance, the tool, and the vibrator downhole into a wellbore;
- and
- operating the vibrator to enhance movement of the tool within the wellbore by creating oscillating forces acting on the tool.
A system for providing oscillations downhole, comprising:
- a downhole tool;
- a vibrator;
- and
- a conveyance coupled to the downhole tool and the vibrator, the vibrator being positioned to create oscillating forces which act on the downhole tool.
A method for providing oscillations downhole, comprising:
- conveying a tool downhole;
- operating the tool at a downhole location to perform a function;
- improving the operational efficiency of the tool by creating oscillating forces which vibrate the tool;
- and
- adjusting the frequency or amplitude of the oscillating forces to optimize the operational efficiency.
