Orientable eccentric downhole assembly

摘要

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.

1. An eccentric zonal isolation completions assembly comprising:
a mandrel to accommodate hydrocarbon production therethrough; a first eccentric isolation packer affixed about a first segment of the mandrel in an off-axis manner; a second eccentric isolation packer adjustably angularly orientable about a second segment of the mandrel in an off-axis manner and coupled to the first segment, wherein the first and second eccentric isolation packers can be oriented with their respective eccentricities out of alignment with one another to achieve a maximum overall diameter and into alignment with one another to achieve a minimum overall diameter; and a control line disposed through the packers for regulation of the production; wherein the mandrel is positioned within a tubing string with the mandrel centered within the tubing string, and wherein the eccentric isolation packers are angularly orientable about the mandrel about an axis aligned with the center of the tubing string.
