Definitions

  • the present invention relates to lubricant compositions for fluids used in well drilling or completion operations. More particularly, the present invention relates to lubricant compositions for water-based drilling fluids used in wellbores.
  • Natural resources such as oil and gas present in the subterranean formation are recovered by drilling a wellbore that penetrates the formation.
  • the drilling operation involves driving by rotation a toothed bit fastened to the end of a drill pipe string.
  • a fluid called drilling fluid or mud
  • the main purpose of the drilling fluid is to cool and lubricate the drill bit as it grinds through the earth’s crust. As the drill bit descends, it generates “cuttings”, or small bits of stone, clay, shale or sand.
  • drilling fluid Other important functions of the drilling fluid are to clean the bit and the well by transporting the cuttings up to the earth’s surface, to provide a hydrostatic pressure to prevent formation fluids from entering into the wellbore, to stabilize the walls of the well, to inhibit reaction of the geologic formations in contact with the fluid, etc.
  • Oil-based and synthetic-based drilling fluids are generally preferred as they produce lower friction and torque values, however, their use may be limited due to the high costs and environment concerns.
  • Water-based drilling fluids are preferred when combating environmental concerns, however, their use is restricted by disadvantages such as high friction and torque values, and interaction of the water-based drilling fluid with the water-sensitive layers of rock which may lead to unacceptable interference with the drilling process.
  • water-based drilling fluids may be used advantageously.
  • Drilling fluid compositions consist of lubricant for the bearing and cutting surfaces of the drill bit and pipe bore.
  • friction may occur between the string of drill pipe and well borehole. This friction may interfere with the vertical movement of the pipe into and out of the well borehole. Due to the increased friction between the drill pipe and the bore hole more power may be required to run the drill pipe, further resulting in increased torque and drag. This consequently leads to stress on the drilling pipe, impacting the drilling process and damaging the drilling tools.
  • a lubricant is an important component of the drilling fluids and completion fluids, and choice of the lubricant is primarily driven by its effectiveness and compliance to environmental regulations.
  • Patent document EP0770661 discloses use of esters of monocarboxylic acids with monohydric alcohols as lubricants for water-based drilling fluid systems. These chemical families are a source of highly lubricious materials that can significantly reduce metal-to-metal and metal-to-rock coefficients of friction in water-based fluid systems by as much as 70%. Typically, the most effective additives have a relatively high degree of surface activity, which improves their adhesion to materials (i.e. metal casing or drilling mud solids), and so enhances the lubricity of the surface.
  • a primary object of the present invention is to provide a lubricant composition for water-based drilling fluids which overcomes the afore-noted drawbacks of the known lubricants, and is environmental-friendly, non-toxic and highly biodegradable. Also, the present invention provides a lubricant composition that prevents bit balling, increases the rate of penetration, increases the drilling rate and minimizes differential sticking problems. Further, the present invention provides a lubricant composition that gives high oxidative stability, high hydrolytic stability and excellent low temperature performance.
  • the present invention discloses a lubricant composition for water-based drilling fluids comprising a synthesized ester obtained by blending at least one polyhydric alcohol and at least one fatty acid, wherein the ratio of said polyhydric alcohol to said fatty acid is in the range of 1 :9 to 9: 1 , and said fatty acid is free of bis- allylic protons.
  • said synthesized ester is obtained by blending said polyhydric alcohol and said fatty acid in the presence of a monobasic acid.
  • the polyhydric alcohol is selected from the group consisting of pentaerythritol, dipentaeryth ritol, tripentaerythritol, monopentaerythritol, and mixtures thereof, more particularly, pentaerythirotol tetraoleate, pentaerythirotol trioleate, pentaerythirotol dioleate, pentaerythirotol monooleate, and mixtures thereof.
  • the fatty acid includes at least one acid selected from the group consisting of ricinoleic acid, oleic acid, stearic acid, palmitic acid, dihydroxystearic acid, linoleic acid, linolenic acid, eicosanoic acid, lauric acid and myristic acid.
  • the fatty acid is a vegetable oil.
  • the vegetable oil may be selected from the group consisting of tall oil, castor oil, sunflower seed oil, canola oil, palm oil, corn seed oil, cotton seed oil, rapeseed oil, linseed oil, safflower seed oil, oat oil, olive oil, peanut oil, apricot seed oil, almond oil, avocado oil, olive oil, camellia oil, rice bran oil, cotton seed oil, peanut oil, walnut oil, rapeseed oil, rice bran oil, linseed oil, sesame oil, soybean oil, palm kernel oil, and mixtures thereof.
  • the monobasic acid is selected from hydrochloric acid, nitric acid, hydrofluoric acid, hydrobromic acid, and mixtures thereof.
  • the ratio of said polyhydric alcohol to said fatty acid is preferably 1 : 1.
  • the lubricant composition is added to a drilling fluid in a concentration in the range of about 1.5% to 3.0% by volume.
  • the lubricant composition of present invention is dispersible. In the various brine systems, said lubricant composition completely eliminates the greasing and cheesing problems.
  • a “lubricant” can be defined as a substance (usually a fluid under operating conditions) introduced between moving surfaces to reduce the friction and wear between them.
  • a lubricant additive is an additive used in drilling fluid to facilitate smooth relative motion of the drilling pipe and the bore hole by minimizing friction and wear between these interacting surfaces.
  • the present invention is an environment-friendly lubricant composition for use as an additive in a drilling fluid system or brine system.
  • the lubricant composition improves drilling fluid performance and efficiency.
  • the lubricant composition is biodegradable, cost-effective and has a low toxicity level.
  • the lubricant composition is an ester-based lubricant derived from natural fats and oils.
  • the lubricant composition when used as an additive in drilling fluid system lubricates the drill bit and the stem, and prevents bit balling, increases the rate of penetration, enhances the drilling rate, reduces the risk of differential sticking and minimizes damage to drilling pipe by twisting or breakage.
  • An embodiment of the present invention discloses a lubricant composition, preferably for water-based drilling fluid systems or brine systems.
  • the lubricant composition comprises a synthesized ester obtained by blending one or more polyhydric alcohols with one or more fatty acids.
  • the lubricant composition is obtained by blending one or more polyhydric alcohols and one or more fatty acids in a preferred ratio in the range of 1 :9 to 9: 1.
  • the ratio of polyhydric alcohol to fatty acid can be taken as 1 : 1.
  • the polyhydric alcohol forms the backbone with the fatty acid group attached to it.
  • the one or more polyhydric alcohols may be selected from the group consisting of glycerol, erythritol, threitol, arabitol, xylitol, ribitol, mannitol, sorbitol, galactitol, fucitol, iditol, inositol, volemitol, isomalt, maltitol, lactitol, maltotriitol, maltotetraitol, polyglycitol, and mixtures thereof.

  • the fatty acid so employed is free of bis-allylic protons.
  • the lubricant composition so obtained possesses high oxidative stability, high hydrolytic stability, excellent low and moderate temperature performance and relatively high biodegradability. Further, the composition is adapted to form a lubricant film having strong interaction with the metallic surfaces.
