A method of cultivating a surface of a wall of a subterranean well bore, a conduit or a cable by scraping and furrowing said surface, said method being characterised by comprising the steps of: cultivating said surface of said wall using at least one apparatus member assembly selectively operated and hoisted by a string across subterranean depths to selectively scrape and urge at least one substantial furrow into a plane of said surface of said wall during one or more arcuate scraping engagements to separate said plane into a plurality of planes having separate surface regions, wherein said at least one apparatus member assembly comprises an above subterranean surface hoistable shaft member carrying a flexible arrangement of an arcuate engagement linkage 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; and extending and retracting, arcuately, said flexible arrangement of said arcuate engagement linkage member laterally from said shaft to carry, arcuately align, and transfer kinetic drag force to at least one cutter and scraper member during said one or more arcuate scraping engagements: along said surface of said wall and longitudinal to a 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 said arcuate engagement linkage member to form and use said at least one substantial furrow, or along and across said surface of said wall and longitudinal and transverse to said well axis to form and use a lattice comprising at least two substantial furrows, wherein said one or more arcuate scraping engagements urges said at least one substantial furrow into said plane to form said plurality of planes to prepare said separate surface regions for subsequent use by an ancillary apparatus or a spreadable substance engageable thereto. cultivating said surface of said wall using at least one apparatus member assembly selectively operated and hoisted by a string across subterranean depths to selectively scrape and urge at least one substantial furrow into a plane of said surface of said wall during one or more arcuate scraping engagements to separate said plane into a plurality of planes having separate surface regions, wherein said at least one apparatus member assembly comprises an above subterranean surface hoistable shaft member carrying a flexible arrangement of an arcuate engagement linkage 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; and extending and retracting, arcuately, said flexible arrangement of said arcuate engagement linkage member laterally from said shaft to carry, arcuately align, and transfer kinetic drag force to at least one cutter and scraper member during said one or more arcuate scraping engagements: along said surface of said wall and longitudinal to a 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 said arcuate engagement linkage member to form and use said at least one substantial furrow, or along and across said surface of said wall and longitudinal and transverse to said well axis to form and use a lattice comprising at least two substantial furrows, wherein said one or more arcuate scraping engagements urges said at least one substantial furrow into said plane to form said plurality of planes to prepare said separate surface regions for subsequent use by an ancillary apparatus or a spreadable substance engageable thereto.
