Abstract
A technique improves the operational characteristics of a well device while the device is used in a wellbore environment. The well device benefits from a unique material, in the form of a negative stiffness material or a negative Poisson's ratio material, positioned to improve the operational characteristics of the well device. The material can be located to reduce vibration and/or other detrimental effects that can interfere with operation of the well device.
Claims20
A method to improve an operational characteristic of a well device, comprising:
- forming at least a portion of the well device with a negative stiffness material, a negative Poisson's ratio material, or a composite having negative stiffness material and/or negative Poisson's ratio material.
A downhole apparatus, comprising:
- a well device sized for deployment in a wellbore, the well device comprising a negative stiffness material, a negative Poisson's ratio material, or a composite having negative stiffness material and/or negative Poisson's ratio material arranged to facilitate a function of the well device.
