Abstract
An assembly employing multiple eccentric devices about a mandrel. The assembly is configured such that at least one of the eccentric devices is adjustably orientable relative another. Thus, for example, where the devices are packers disposed about completions tubing, the adjustable orientation may be utilized to ensure enough clearance is available for downhole advancement of the assembly. As such, the assembly may remain eccentric in nature without concern over damage during positioning, particularly to a communication line running to actuatable implements of equipment coupled to the completions assembly.
Claims25
An eccentric completions assembly comprising:
- a mandrel;
- a first eccentric device affixed about a first segment of said mandrel;
- and
- a second eccentric device adjustably orientable about a second segment of said mandrel coupled to the first segment.
An assembly comprising:
- a mandrel;
- a plurality of eccentric devices disposed about said mandrel, at least one of said devices adjustably orientable relative said mandrel for alignment with another of said devices.
A method of performing an application at a location in a well, the method comprising:
- coupling a downhole tubing segment to an uphole tubing segment to form a completions assembly;
- adjustably orienting a first eccentric device of one of the segments with a second eccentric device of the other segment;
- and
- advancing the assembly to the location.
An oilfield assembly comprising:
- a tubing;
- a plurality of eccentric devices disposed about said tubing, at least one of said devices adjustably orientable relative said tubing for alignment with another of said devices;
- and
- fluid flow equipment coupled to said tubing for an application therethrough.
