Abstract: A multi-functional apparatus and method for drilling fluid and cementing operations to set casing in a wellbore for use on either top drive or rotary type rigs. The apparatus and method includes a fill-up and circulating tool, a cementing head assembly, and a wiper plug assembly. The fill-up and circulating tool comprises a mandrel with a sealing element disposed about the outside diameter of the mandrel. The cementing head and wiper plug assemblies are useable on any fill-up and circulating tool capable of being inserted into a casing. To fill the casing, the assembly is lowered from the rig such that a portion of the fill-up tools inserted into the casing, the pumps are then actuated to flow fluid into the casing. To circulate fluid, the tool is lowered further such that the sealing element sealingly engages the inside diameter of the casing to allow fluid to flow through the casing, into the wellbore, and back to the fluid pumps.

Abstract: A temperature activated actuator installed on a tubular to actuate an adjacent device may include one or more shape-memory alloy elements. The elements may be coupled between a first portion and a second portion of a device, or the elements may be coupled between the tubular and a portion of the device. The elements are activated by raising the temperature to a transition temperature to cause metallurgical phase transformation, causing the elements to shrink and displace at least a portion of the device. The actuator may be used, for example, to actuate a centralizer from a run-in mode to a deployed mode or, alternately, to actuate a packing member from a run-in mode to an isolating mode. A nickel-titanium alloy, for example, may be used as the shape-memory alloy material from which the shape-memory element is made.
