Title: Heating production fluids in a wellbore

Abstract

A method for heating a production fluid in a wellbore. The method can include heating, using a packer fluid, a working fluid flowing through a first medium disposed in a first section of the wellbore, where the first medium transfers heat from the packer fluid to the working fluid. The method can also include circulating the working fluid into a second section of the wellbore through a second medium, where the second medium transfers heat from the working fluid to the production fluid. The method can further include returning the working fluid to the first section of the wellbore through the first medium.

  • Hydrocarbons are recovered from oil shale deposits by introducing hot fluids into the deposits through wells and then shutting in the wells to allow kerogen in the deposits to be converted to bitumen, which is then recovered through the wells after an extended period of soaking. Heat energy is introduced in quantities sufficient to heat the deposit in the vicinity of the wells to more than 50/sup 0/F (Fahrenheit Degrees) above its transition temperature (the temperature at which exfoliation of the shale structure commences). Introduction of heat energy to a shale deposit can be by any suitable means with usemore » of hot fluids at temperatures between about 700/sup 0/ and about 2,000/sup 0/F being preferred. Preferred fluids include steam and hot water, although other fluids not containing free oxygen, such as liquid or vaporous hydrocarbons, flue gas, etc. may be used. (JGB)« less
  • The present invention is directed to a gas-lift system for facilitating the removal of fluid (liquid and/or gaseous) energy values from a subterranean geologic earth formation penetrated by a horizontally extending wellbore. In accordance with the present invention concentric tubing is disposed in the wellbore with the outer tubing being provided with one-way valves for admitting the fluids from the earth formation surrounding the tubing. These fluids flow into an annulus between the tubings and are expelled from the annulus by injecting a gas into the annulus between the tubes which closes the valves and flushes the liquids from themore » tubing by forcing the fluids through the inner tube to a surface collection point.« less
  • This is a patent for wellbore treating fluids containing densifying salt dissolved in a solvent for this salt. This solvent contains at least about 50 percent by weight of a liquid non-aqueous solvent such as, e.g., N-methyl-2-pyrrolidone, such that the overall solvent has desirable properties with respect to the ability to dissolve salt, miscibility with water, melting point, boiling point, flash point and viscosity. Examples of such wellbore treating fluids include drilling, completion, packer and workover fluids.
  • Calcined dolomite stabilizes aqueous solutions of viscosifiers, such as polysaccharides, exposed to temperatures as high as 200/sup 0/F. (93/sup 0/C) for prolonged periods.
  • A method is described for distributing fluids within a subterranean borehole around equipment to be protected, the method consists of the steps of: introducing into the borehole at a first location apparatus comprising a submersible pump having an intake port connected to a first end of an intake duct and having an output port connected to a first end of an output duct; positioning a free second end of the intake duct within the borehole at a second location from which fluid is to be withdrawn, the second location being on a first side of the equipment to be protected;more » locating a free second end of the output duct within the borehole at a third location into which fluid is to be introduced, the third location being on a second side of the equipment to be protected; activating the submersible pump; and providing a treatment fluid to the second location, the treatment fluid selected from the group consisting of a corrosion inhibitor, a defoamer, an emulsion breaker, a focculant, a paraffin inhibitor, a bactericide and mixtures thereof.« less
