Apparatus and method for cultivating a downhole surface

A method of forming and arranging an apparatus (2) member assembly to cultivate (1) a surface (6) of a wall of a subterranean well bore, a conduit or a cable by scraping at least one substantial furrow therein, said method comprising the steps of:

• forming, providing and selectively arranging said apparatus member assembly with an above subterranean surface string hoistable shaft (3) member for carrying a flexible arrangement of an arcuate engagement linkage (4) that is arcuately extendable and retractable laterally and carries a draggable at least one cutter and scraper member (5) and with a member engagement mechanism (129) that is selectively:
• fixable, slideable, rotatable, shearable, or combinations thereof, wherein the member engagement mechanism (129) is usable to axially move (38) or rotationally move (39) said one or more arcuate scraping engagements to selectively transfer said kinetic drag force;
• forming and arranging said arcuate engagement linkage with at least one of said member engagement mechanisms (129) comprising:
• a rigid (30) part flexibly operable via a pivotal part, a flexible (31) part, or combinations thereof, wherein the at least one of said member engagement mechanisms (129) is usable during said axial movement (38) or said rotational movement (39) of said one or more arcuate scraping engagements to flexibly and laterally transfer kinetic drag force from said above subterranean surface string hoistable shaft member through said arcuate engagement linkage having an arcuate shape or an arcuate engagement of said flexible arrangement and an alignment of said draggable at least one cutter and scraper member during one or more arcuate scraping engagements:
• along said surface of said wall and longitudinal to said well axis to form and use said at least one substantial furrow, across said surface of said wall and transverse to said well axis using a filament-like arcuate engagement linkage to form and use said at least one substantial furrow, along and across said surface of said wall longitudinal and transverse to said well axis to form and use a lattice of said at least one substantial furrow, and
• arranging said apparatus member assembly for selectively hoisting said apparatus member assembly across subterranean depths to selectively operate said one or more arcuate scraping engagements and urge said at least one substantial furrow (11) into a plane of said surface of said well to separate said plane into a plurality of planes comprising separate surface regions (9) usable by an ancillary apparatus (7) or a spreadable substance (8) engagable thereto.

An apparatus (2) for cultivating (1) a surface (6) of a wall of a subterranean well bore, a conduit or a cable by scraping at least one substantial furrow therein, said apparatus comprising:

• at least one above subterranean surface string hoistable shaft (3) member comprising at least one housing (27) with at least one axial passage (24), a lateral opening (23), or combinations thereof, usable to communicate and move a fluid or a mechanical arcuate engagement linkage cutter and scraper member therethrough (28) or thereabout (29), wherein said at least one above subterranean surface string hoistable shaft (3) member carries a flexible arrangement of a arcuately extendable and retractable arcuate engagement linkage (4) member having a shape, a movement-path, or combinations thereof, of an arc flexibly extendable and retractable between said hoistable shaft and said surface of said wall to align and carry a draggable at least one cutter and scraper member (5);
• and
• said arcuate engagement linkage member arranged to laterally transfer kinetic drag force and arcuately extend, retract, engage and align said draggable at least one cutter and scraper member (5) during one or more arcuate scraping engagements:
• along said surface and longitudinal to said well axis using a bascule-like linkage or a filament-like linkage to form and use said at least one substantial furrow, across said surface and transverse to said well axis using said filament-like linkage to form and use said at least one substantial furrow, along and across said surface and longitudinal and transverse to said well axis to form and use a lattice of said at least one substantial furrows,
• wherein selectively hoisting of said one or more arcuate scraping engagements selectively urges said at least one substantial furrow (11) into a plane of said surface of said wall to separate said plane into a plurality of planes comprising separate surface regions (9) usable by an ancillary apparatus (7) or a spreadable substance (8) engaged thereto.

An apparatus (2) for cultivating (1) a surface (6) of a wall of a subterranean well bore, a conduit or a cable by scraping at least one furrow therein, said apparatus comprising:

• at least one above subterranean surface string hoistable shaft (3) member carrying a flexible arrangement of an arcuately extendable and retractable arcuate engagement linkage (4) member having a shape, a movement-path, or combinations thereof, of an arc flexibly extendable and retractable between said hoistable shaft and said surface of said wall to align and carry at least one cutter and scraper member (5);
• and
• said arcuate engagement linkage member arranged to laterally transfer kinetic drag force and arcuately extend, retract, engage and align said at least one cutter and scraper member (5) during one or more arcuate scraping engagements:
• along said surface and longitudinal to said well axis using a bascule-like linkage or a filament-like linkage to form and use said at least one furrow, across said surface and transverse to said well axis using said filament-like linkage to form and use said at least one furrow, along and across said surface and longitudinal and transverse to said well axis to form and use a lattice of said at least one furrows,
• wherein selectively hoisting of said one or more arcuate scraping engagements selectively urges said at least one furrow (11) into a plane of said surface of said wall to separate said plane into a plurality of planes comprising separate surface regions (9) usable by an ancillary apparatus (7) or a spreadable substance (8) engaged thereto, and
• wherein said arcuate engagement linkage (4) member comprises a part comprising a disposable fibre (47), a plastic (48), or combinations thereof (49), and wherein said part is detachable from said apparatus for disposal within said subterranean well bore.
