A collet comprising a collet ring, a plurality of collet fingers, and an object seat (e.g., ball seat), wherein the object seat comprises a surface (e.g., a curved surface) configured to interface with a correspondingly sized blocking object (e.g., a ball, dart, etc.) to form a seal therebetween, wherein each of the plurality of collet fingers has a first end and a second end, wherein the first end is proximate the collet ring, and wherein the second end of at least a portion of the plurality of collet fingers comprises a key (e.g., a tab) that is configured to engage a corresponding latch of a downhole structure.

Electrical connections between different materials. An electrical connection system includes electrical components and an electrical connection between the electrical components. The electrical connection includes a functionally graded material. A method of making an electrical connection between different materials includes the steps of: providing an electrical component which includes a material; providing another electrical component which includes another material; and electrically connecting a functionally graded material between the electrical components. An electrical connection system includes an electrical component and a functionally graded material electrically connected to the electrical component. The functionally graded material provides a gradual transition between at least two dissimilar materials.

A well system having a galvanic time release plug. A well system includes a flow passage and a flow blocking device which selectively obstructs flow through the passage, the device including an electrode in a galvanic cell. A flow blocking device for use in conjunction with a subterranean well includes a portion which delays an electrochemical reaction in a galvanic cell. A method of controlling fluid flow in a well system includes the steps of: obstructing flow through a passage using a flow blocking device which includes an electrode of a galvanic cell; and increasing flow through the passage by operation of the galvanic cell.

A downhole seal () includes an elastomeric element () operably to provide a seal between two downhole components. A strain sensor () is embedded in the elastomeric element (). The strain sensor () has a mechanical flexibility that is substantially matched to the mechanical flexibility of the elastomeric element (). The strain sensor () is operably connected to circuitry that is operable to identify changes in a property of the strain sensor () indicative of the strain being experienced by the strain sensor (), which is representative of the strain experienced by the elastomeric element ().
