Abstract:
A thermally insulating fluid composition comprising a glycol solvent for a viscosifier, a viscosifier, and optionally, an aqueous brine. The glycol may be selected from a propylene glycol, or under excessive heat temperatures, a butylene glycol, which can be used with or without a viscosifier. Viscosifiers can be selected from hydroxy propyl methyl cellulose, xanthan and hydroxy propyl guar and combinations thereof. In one method of producing the thermally insulating composition, a viscosifier is added to an aqueous brine, water is then added to that solution followed by the addition of dry salt of the brine to increase density if necessary. A propylene glycol solvent is added to the resulting solution. The thermally insulating fluid composition insulates substances stored or transported in multi-walled vessels, tanks, piping and thermal units. A method of applying the insulating fluid composition of this invention comprises the steps of injecting the thermally insulating fluid into the cavity formed by two adjacent walls of the vessel or piping and then sealing off the opening.

Also an apparatus for forming a plug in a well comprises means for filling a length of the well with a molten material the melting point of which is higher than the temperature within the well and which expands as the material solidifies upon cooling to the temperature within the well.
Abstract:
A method and system for the treatment and, in particular, the cooling of natural hydrocarbons originating in a hydrocarbons reservoir. A coolant fluid conduit (5) is provided and is connected to a hydrocarbon production fluid conduit (11) to allow a controllable volume of coolant fluid to be added to the hydrocarbon production fluid conduit at a predetermined position (23) upstream of the wellhead and downstream of the hydrocarbon reservoir.
Abstract:
A method for treating a hydrocarbon containing formation is provided. In one embodiment, heat from one or more heaters may be provided to at least a portion of the formation. Heat may be allowed to transfer from the one or more heaters to a section of the formation. In certain embodiments, the heat from the one or more heaters may pyrolyze at least some hydrocarbons within the section. In an embodiment, a first fluid may be introduced into at least a portion of the formation. The portion may have previously undergone an in situ conversion process. A mixture of the first fluid and a second fluid may be produced from the formation.
Abstract:
A method is disclosed for treating a hydrocarbon containing formation in situ and producing a hydrocarbon fluid from the formation, wherein hydrocarbons present in the formation are pyrolysed at an elevated pressure with the application of a pressure/temperature control such that the pressure is at least the pressure which can be calculated for a selected temperature, or the temperature is at most the temperature which can be calculated for a selected pressure from the equation (I) wherein P is pressure (bar absolute), T is temperature ( DEG C), and A and B are predetermined parameters which relate to a property which is relevant to the quantity, the composition or the quality of the hydrocarbon fluids produced. Optionally the method is followed by the step of producing synthesis gas in-situ which step comprises reacting the hydrocarbon containing formation that has been treated with the method according to the invention with a synthesis gas generating fluid. Optionally converted hydrocarbons are produced by converting the synthesis gas so produced into hydrocarbons and/or energy is generated by expanding and/or combusting the synthesis gas so produced or using the synthesis gas so produced in a fuel cell.
Abstract:
The present invention provides a method for the production of synthesis gas from a hydrocarbon-containing subterranean formation comprising: providing heat to at least a portion of the subterranean formation such that at least a part of the heated portion reaches the pyrolysis temperature of kerogen, yielding pyrolysis products; collecting pyrolysis products from the subterranean formation; injecting a synthesis gas-generating component into the heated part of the formation, resulting in the production of synthesis gas by reaction of the synthesis gas-generating component with carbonaceous material remaining in the formation; and recovering synthesis gas. The synthesis gas thus produced can be used for Fischer-Tropsch synthesis, manufacture of ammonia, urea, methanol, methane and other hydrocarbons, or used as energy source, e.g. in fuel cells. Carbon dioxide produced in such use of the synthesis gas can be sequestered in the formation.

The present invention provides a method for the in-situ pyrolysis of hydrocarbons in a subterranean kerogen-containing formation, comprising: providing heat to at least a portion of the kerogen-containing formation such that at least a part of the heated portion reaches the pyrolysis temperature of kerogen, yielding pyrolysis products; and collecting pyrolysis products from the subterranean formation; wherein the subterranean formation is selected to comprise kerogen with a vitrinite reflectance of 0.2 to 3.0 %. Further, the invention provides a method for synthesis gas production after the collection of pyrolysis products by allowing the kerogen-containing formation to react with a synthesis gas generating fluid.
