Definitions

  • the invention relates generally to wellbore fluids. More particularly, the present invention relates to non-aqueous, non-corrosive packer fluids.
  • packer fluid means a fluid that is left in the annular region of a well between tubing and outer casing above a packer.
  • the main functions of a packer fluid are: (1) to provide hydrostatic pressure in order to lower differential pressure across a sealing element, (2) to lower differential pressure on a wellbore and casing to prevent collapse and (3) to protect metals and elastomers from corrosion or deterioration.
  • they should be of sufficient density to control the producing formation, be solids-free and resistant to viscosity changes over long periods of time, and be noncorrosive to the wellbore and completion components.
  • the present invention relates to a method of treating a well including injecting a substantially water- free well-treating fluid into the well, where the well-treating fluid comprises a glycol compound and an organic liquid, the glycol compound and the organic liquid being present in amounts selected to achieve a predetermined density.
  • the present invention relates to a substantially water- free well fluid including a glycol compound and an organic liquid, where the glycol compound and the organic liquid are present in amounts selected to achieve a predetermined density.
  • the present invention relates to a method of treating a well including injecting a well-treating fluid into the well, where the well-treating fluid comprises water, a glycol compound, and other organic liquids in which the combination of fluids meets pre-set performance characteristics such as density, viscosity, hydrate inhibition, and compatibility with other fluids and elements in the annulus.
  • the present invention relates to a well fluid that includes water, a glycol compound, and other organic liquids in which the combination of fluids meets pre-set performance characteristics such as density, viscosity, hydrate inhibition, and compatibility with other fluids and elements in the annulus.
  • the present invention relates to a well fluid that includes a glycol compound, and a quaternary amine salt, where the glycol compound and the quaternary amine salt are present in amounts selected to achieve a predetermined density.
  • Glycols such as ethylene glycol, propylene glycol, and others can be mixed at a very broad range of ratios with water and/or organic liquids such as alcohols, glycol ethers and others to form fluid mixtures having densities ranging from low ( ⁇ 7 lbm/gal) to high (-11 lbm/gal), depending on desired properties.
  • Lbm/gal is a unit of density, which one of ordinary skill in the art would interpret as pound per gallon, or more specifically pound mass per gallon.
  • Such mixtures inhibit hydrates because the mixture is either substantially free of water or the water is made inhibitive by virtue of the glycol and alcohol.
  • the present invention describes the development of non-aqueous, non-solids laden, non-corrosive, hydrate inhibitive well fluids (or packer fluids) for use in oil field production annuli.
  • the well fluids are prepared to desired densities for annular pressure control by proportioning miscible, non-aqueous fluids together.
  • the non-aqueous fluids include glycols, glycol-ethers, alcohols and other organic liquids.
  • the well fluids may contain soluble salts to achieve specific densities.
  • the well fluids may be viscosified with synthetic or biopolymers to reduce convective currents, needed in some cases for annular heat insulation.
  • the present invention describes the development of non-solids laden, non-corrosive, hydrate inhibitive well fluids for use in oil field production annuli.
  • the fluid is prepared to desired densities for annular pressure control by proportioning miscible fluids together with water.
  • These fluids include glycols, glycol-ethers, alcohols and other organic liquids.
  • the fluids may contain soluble salts to achieve specific densities.
  • the fluids may be viscosified with synthetic or biopolymers to reduce convective currents, needed in some cases for annular heat insulation.
  • glycol compound and an organic liquid may be mixed in amounts sufficient to yield a desired density.
  • multiple glycol compounds and multiple organic liquids may be mixed, with or without water, so long as the mixture remains a solution.
  • a well fluid in accordance with one embodiment of the present invention comprises a mixture of 0.2 barrels of methanol, 0.35 barrels of monoethylene glycol (MEG), 0.42 barrels of water, and a sufficient amount of a CaBr 2 solution, having a density of 14.5 ppg, to form a well fluid, referred to as formulation 1 herein, having an overall density of approximately 8.6 ppg.
  • formulation 1 having an overall density of approximately 8.6 ppg.
  • a well fluid in accordance with one embodiment of the present invention comprises a mixture 0.2 barrels of methanol, 0.35 barrels of monoethylene glycol (MEG), 0.42 barrels of water, and a sufficient amount of a CaBr 2 solution, having a density of 15.3 ppg, to form a well fluid, referred to as formulation 2 herein, having an overall density of approximately 8.8 ppg. While particular salts, and particular densities are referenced in the above embodiments, it should be understood that the salt types and concentrations may also vary from zero to saturation, according to density / compatibility requirements.
  • aqueous fluids are susceptible to gas hydrate formation if high-pressure gas is encountered. Typical oilfield pressures exceed 8,000 psi.
  • An additional consideration is that well fluids having a density of 8.6 ppg (achievable with 3.5-4.5 wt% salt) are often used. This salt concentration is not adequate to prevent hydrate formation under the combination of low salinity fluid, low temperature and high gas pressure, should such a combination occur in the wellbore. Therefore, other means of hydrate prevention, while maintaining density control, are desired.
  • the present invention has discovered that advantageously, mixtures of glycol and organic liquids are effective hydrate inhibitors.
  • formulations are produced involving (1) halide brines, formate brines, and acetate brines, such as, for example, those based on tetramethylammonium chloride, tetramethylammonium bromide, tetramethylammonium formate, tetramethylammonium acetate, tetraethylammonium chloride, tetraethylammonium bromide, tetraethylammonium formate, tetraethylammonium acetate, tetrapropylammonium chloride, tetrapropylammonium bromide, tetrapropylammonium formate, tetrapropylammonium acetate, tetrabutylammonium chloride, tetrabutylammonium bromide, tetrabutylammonium formate, tetrabutylammonium formate, tetrabut
  • the present invention relates to well fluids comprising a glycol compound and a quaternary amine salt.
  • the glycol compound and quaternary amine may be mixed with an organic liquid, as described above, or with numerous other compounds.
  • mixtures of any or all of the above compounds may be used in connection with the present invention. The above list is not intended to be a comprehensive list of all suitable mixtures within the scope of the present invention.
  • One of ordinary skill in the art, having reference to this specification, will recognize that other mixtures are within the scope of the present invention.
  • a solution comprising 200 grams of ethylene glycol and 150 grams of tetrabutylammonium bromide was prepared.
  • the solution had a density of 9.0 ppg and a TCT (Thermodynamic Crystallization Temperature) ⁇ 25°F.
  • TCT Thermodynamic Crystallization Temperature
  • This fluid is highly inhibitive of hydrates.
  • salts like CaBr 2 , NaCl, and the like, cause the density of ethylene glycol to increase upon the addition of the salt to the ethylene glycol.
  • salt for example, tetrabutylammonium bromide
  • the density decreases.
  • Other salts that exhibit this surprising behavior include tetramethylammonium chloride, tetramethylammonium acetate, and the like.
  • a solution comprising 200 grams of ethylene glycol and 400 grams of tetrabutylammonium bromide was prepared.
  • the solution had a density of 9.0 ppg, substantially the same as that of the third example, another highly surprising result - that a substantial amount of a salt with density substantially greater than 9.0 ppg could be added to a solution without any appreciable density increase in the solution.
  • This fluid is highly inhibitive of hydrates.
  • a suitable well fluid having a predetermined density may comprise 20% to 50% of methanol and 20% to 50% of monethylene glycol of the total weight percentage. More preferably, in one or more embodiments, a suitable well fluid having a predetermined density may comprise 30% to 45% of methanol and 30% to 45% of monoethylene glycol of the total weight percentage. Still more preferably, in one or more embodiments, a suitable well fluid may comprise 35% to 40% of methanol and 35%o to 40% of monoethylene glycol of the total weight percentage.
  • a suitable well fluid may comprise a density of 5 ppg to 9 ppg. More preferably, in one or more embodiments, a suitable well fluid may comprise a density of 8.2 ppg to 8.8 ppg. Still more preferably, in one or more embodiments, a suitable well fluid may comprise 8.3 ppg to 8.5 ppg.
  • fluids disclosed herein may also be used as fluids in or in connection with drilling, drill-in, displacement, completion, hydraulic fracturing, work-over, well-treating, testing, or abandonment.
