(canceled) ### Claim 1 An anchoring mechanism configured for coupling to a flow conductor, emplaceable within a wellbore that is lined with casing, wherein the anchoring mechanism is configurable in an anchoring-effective state for effectuating anchoring of the flow conductor to the casing; wherein: the anchoring mechanism is co-operable with the casing such that, while: (i) the anchoring mechanism is coupled to the flow conductor that is disposed within the wellbore that is lined with the casing, and (ii) the anchoring mechanism is disposed in the anchoring-effective state such that the flow conductor is anchored by the anchoring mechanism to the casing, the flow conductor is eccentrically disposed relative to the central longitudinal axis of the wellbore. ### Claim 2 (depends on 1) The anchoring mechanism as claimed in claim 1; wherein: the eccentric disposition of the flow conductor relative to the central longitudinal axis of the wellbore is such that a ratio of a minimum distance “D1”, by which the central longitudinal axis of the flow conductor is spaced apart from the casing, to a minimum distance “D2”, by which the central longitudinal axis of the wellbore is spaced apart from the casing, is less than 0.2. ### Claim 3 (depends on 1) The anchoring mechanism as claimed in claim 1; wherein: the anchoring mechanism is transitionable from an anchoring ineffective state to the anchoring effective state; the anchoring mechanism includes an anchor configuration that includes a first anchor and a second anchor, wherein the first anchor is disposed on an opposite side of the flow conductor relative to a side of the flow conductor on which the second anchor is disposed; the anchoring mechanism is co-operable with the casing such that, while the anchoring mechanism is coupled to the flow conductor that is disposed within the wellbore that is lined with casing, the transitioning is with effect that each one of the first and second anchors, independently, becomes displaced outwardly relative to the central longitudinal axis of the flow conductor, such that the anchoring of the flow conductor to the casing is effectuated; and a ratio of the outward displacement of the first anchor to the outward displacement of the second anchor is at least 2.5. ### Claim 4 (depends on 1) The anchoring mechanism as claimed in claim 1; wherein: the flow conductor includes a production string. ### Claim 5 A downhole tool configured for emplacement within a wellbore that is lined with casing, comprising: a casing engagement configuration configured for engaging the casing; and a pusher; wherein: the casing engagement configuration and the pusher are co-operatively coupled such that: (i) the casing engagement configuration is axially moveable with the pusher, and (ii) the pusher is rotatable relative to the casing engagement configuration. ### Claim 6 (depends on 5) The downhole tool as claimed in claim 5; wherein: the rotatability of the pusher relative to the casing engagement configuration is such that, while torque is being applied to the pusher, there is an absence of transmission of the torque from the pusher to the casing engagement configuration. ### Claim 7 (depends on 5) The downhole tool as claimed in claim 5; wherein: the rotatability of the pusher relative to the casing engagement configuration is a rotatability about an axis that is parallel to the axis along which the casing engagement configuration is moveable with the pusher. ### Claim 8 (depends on 5) The downhole tool as claimed in claim 5; wherein: the casing engagement configuration includes a drag block configuration; and the drag block configuration is co-operable with the casing, such that, while the downhole tool is disposed within the wellbore, the drag block configuration is biased towards the casing for effectuating contact engagement of the drag block configuration with the casing, with effect that axial movement of the downhole tool is resisted. ### Claim 9 (depends on 8) The downhole tool as claimed in claim 8; wherein: the drag block configuration includes at least one drag block. ### Claim 10 (depends on 5) The downhole tool as claimed in claim 5; further comprising: an actuator tool including a j-slot wherein: the pusher is co-operable with the J-slot, such that a force being applied to the actuator tool is transmittable to the pusher via the J-slot. ### Claim at position 12 11-17. (canceled) ### Claim 18 An anchoring mechanism configured for coupling to a flow conductor, emplaceable within a wellbore that is lined with casing, comprising: a scraper configured for scraping a portion of the casing such that a conditioned casing portion is obtained; and an anchor for anchoring the flow conductor to the conditioned casing portion. ### Claim 19 (depends on 18) The anchoring mechanism as claimed in claim 18; wherein: the anchoring mechanism is co-operable with the flow conductor such that, while the anchoring mechanism is coupled to the flow conductor and the flow conductor is emplaced within the wellbore, the scraper is disposed uphole relative to the anchor. ### Claim 20 (depends on 18) The anchoring mechanism as claimed in claim 18; wherein: the scraper is aligned with the anchor along a longitudinal axis of the anchoring mechanism. ### Claim 21 (depends on 18) The anchoring mechanism as claimed in claim 18; wherein: the scraper is biased towards the casing for effectuating contact engagement of the scraper with the casing, such that, while the scraper is disposed in contact engagement with the casing, and the anchoring mechanism is being axially displaced through the wellbore, the scraping of the casing portion is being effectuated. ### Claim 22 (depends on 18) The anchoring mechanism as claimed in claim 18; wherein: the scraper defines at least one blade for effectuating the scraping. ### Claim 23 (depends on 18) The anchoring mechanism as claimed in claim 18; further comprising: a rocker; wherein: the anchor is disposed at one end of the rocker, and the scraper is disposed at another end of the rocker. ### Claim 24 (depends on 18) The anchoring mechanism as claimed in claim 18; wherein: the scraper is spaced apart from the anchor by a minimum distance of less than five (5) feet. ### Claim at position 20 25-30. (canceled) ### Claim 31 (depends on 5) The downhole tool as claimed in claim 5; further comprising: a mandrel including a support, a retainer, and the pusher; wherein: the casing engagement configuration is mounted on the support; the retainer is threadably coupled to the anchor support, and the pusher is disposed between the support and the retainer, and the support, the retainer, and the pusher are co-operatively configured such that the threadable coupling of the retainer to the anchor support defines space sufficient for retention of the pusher between the retainer and the support such that axial movement of the pusher relative to the retainer and the support is restricted while, in parallel, the pusher is free to rotate relative to the threadably coupled retainer and support. ### Claim 32 (depends on 31) The downhole tool as claimed in claim 31; wherein: the casing engagement configuration includes a draft block; and the draft block is biased outwardly relative to a longitudinal axis of the mandrel. ### Claim 33 (depends on 10) The downhole tool as claimed in claim 10; wherein: the actuator tool defines a flow passage.
