Claims
1. A method for reducing friction when using radial drilling, the method comprising: coating the inside of the deflector shoe with at least one lubricant.
2. The method according to paragraph 1, characterized in that it additionally includes the step of: applying a wet lubricant to the wellbore and to the inside of the whipstock shoe, wherein the wet lubricant contains a liquid mixed with a friction reducer.
3. The method according to paragraph 1, characterized in that the coating step includes: applying dry lubricant to the inside of the deflector shoe; hardening of the applied dry lubricant; and applying wet lubricant over hardened dry lubricant.
4. The method according to paragraph 1, characterized in that it additionally includes: coating the hose with at least one lubricant; and passing the hose through the coated inside of the deflector shoe.
5. The method according to paragraph 1, characterized in that it additionally includes: coating the jet nozzle with at least one lubricant; and passing a jet nozzle through the coated interior of the deflector shoe.
6. The method according to paragraph 1, characterized in that it additionally includes: coating the components of the milling cutter with at least one lubricant; and passing the milling cutter components through the coated interior of the deflector shoe.
7. The method of claim 1, wherein at least one lubricant is selected from the group consisting of: tire polish, fluoropolymer coatings, tungsten disulfide coating, polytetrafluoroethylene, molybdenum disulfide, graphite, silicone, epoxy resin, and Never Seez®.
8. The method according to paragraph 1, characterized in that it additionally includes the step of: roughening the inside of the deflector shoe before the coating stage.
9. The method according to claim 8, characterized in that the roughening step includes grinding the inner part of the deflector shoe with sandpaper.
10. A method for reducing friction when using radial drilling, the method comprising: roughening the inside of the deflector shoe; coating the inside of the deflector shoe with at least one lubricant; passing the hose through the coated inside of the deflector shoe; and applying wet lubricant to the deflector shoe during the pass stage.
11. The method of claim 10, wherein at least one lubricant applied to the deflector shoe comprises a hardened dry lubricant with a layer of wet lubricant on top of the hardened dry lubricant.
12. The method according to paragraph 10, characterized in that it additionally includes the step of: coating the outer portion of the hose with at least one lubricant prior to the passing step.
13. The method according to paragraph 10, characterized in that it additionally includes the step of: coating the jet nozzle with at least one lubricant; and passing a jet nozzle through the coated interior of the deflector shoe.
14. The method according to paragraph 10, characterized in that it additionally includes the step of: coating the components of the milling cutter with at least one lubricant; and passing the milling cutter components through the coated interior of the deflector shoe.
15. The method of claim 10, wherein at least one lubricant is selected from the group consisting of: tire polish, fluoropolymer coatings, tungsten disulfide coating, polytetrafluoroethylene, molybdenum disulfide, graphite, silicone, epoxy resin, and Never Seez®.
16. The method according to claim 10, characterized in that the stage of applying wet lubricant is continuous during the drilling process, wherein the wet lubricant is a liquid mixed with a friction reducer.
17. An apparatus for reducing friction when using radial drilling, the apparatus comprising: a deflector shoe having an inner surface; at least one lubricant applied to the inner surface of the deflector shoe.
18. The apparatus according to item 17, characterized in that the inner surface of the deflector shoe is roughened before applying the lubricant.
19. The apparatus of claim 17, wherein said at least one lubricant comprises a hardened dry lubricant with a layer of wet lubricant on top of the hardened dry lubricant.
20. The apparatus of claim 17, wherein at least one lubricant is selected from the group consisting of: tire polish, fluoropolymer coatings, tungsten disulfide coating, polytetrafluoroethylene, molybdenum disulfide, graphite, silicone, epoxy resin, and Never Seez®.
