Abstract: A downhole tool for use in a well comprising a mandrel and an outer sleeve slidably disposed about the mandrel. An inner sleeve is slidably disposed in the mandrel. A drive pin comprising a drive pin bushing connected to the outer sleeve and a shear pin connected to the inner sleeve connects the inner sleeve to the outer sleeve.

Abstract: The present disclosure includes a plug for cementing a wellbore. The plug may include a cylinder. The cylinder may include at least one body including a non-conductive material with conductive filaments dispersed within the non-conductive material. The present disclosure also includes float equipment for cementing a wellbore. The float equipment may include a casing segment including an inner surface, drillable material affixed to the inner surface of the casing segment, and a check valve attached to the drillable material. The drillable material may include a non-conductive material and conductive filaments dispersed within the non-conductive material.

Abstract: A single sleeve, multi-stage cementing tool for cementing in a wellbore can include a tool body, an outer mandrel, a flow port for providing fluid communication transversely from the inside of a tubing string into an annulus, and a port plug. The port plug is located within the flow port during first stage cementing such that the cement flows into the annulus from a bottom of the tubing string. The bottom of the tubing string can be closed after the first stage, and the port plug can be released from the flow port by increasing pressure within the tubing string. Second stage cementing can then be performed such that the cement flows into the annulus directly through the opened flow port. After all cement stages have been completed, a closing sleeve can be shifted to close the flow port.
