Abstract: In accordance with embodiments of the present disclosure, systems and methods for determining a dynamic effective elastic modulus of a composite slickline or wireline cable are provided. A system for estimating the effective elastic modulus (or change thereof) may include a sensing head assembly, a vibration generator, a pair of pulleys, and an optical-based signal processing assembly. The system may detect a resonant frequency of a section of the composite cable held between the two pulleys and estimate the effective elastic modulus based on the detected resonant frequency variation. Adjustments for weight and length of the cable extending into the wellbore may be made as well to determine the dynamic elastic modulus of the cable. The opto-mechanical integrated system described below may enable real-time elastic modulus determination. The system may provide a non-contact inspection method for monitoring mechanical fatigue of a composite cable without interfering with the composite cable intervention operation.

Abstract: An object of this invention is to detect an external force or acceleration with good sensitivity using a simple configuration. An external force detection sensor comprises a comb electrode including a fixed electrode having a plurality of fixed combtooth portions and a movable electrode having a plurality of movable combtooth portions inserted between the fixed combtooth portions; a power supply connected to the fixed electrode and the movable electrode in order to cause vibration of the movable electrode at a prescribed resonance frequency through an electrostatic force on the fixed electrode; and detection means for detecting an external force based on a change in electrical characteristics between the fixed electrode and the movable electrode when the movable electrode is caused to vibrate. With respect to the fixed combtooth portions that are adjacent to each other and the movable combtooth portion inserted therebetween, the spacing between one of the fixed combtooth portions and the movable combtooth portion is different from the spacing between another of the fixed combtooth portions and the movable combtooth portion.
