Definitions

  • the present invention relates to production of crude oil from a hydrocarbon-beanng underground zone, wherein the crude oil is produced through a wellbore extending from the hydrocarbon-beanng zone to a well head at surface.
  • the phrase 'extending from the hydrocarbon-beanng zone' is intended to cover extending through the hydrocarbon-bearing zone as well.
  • a well is a wellbore that is for at least the larger part of its length lined with a casing, wherein the casing can be absent at the hydrocarbon-beanng zone, or wherein the casing can extend along the entire length of the wellbore. In the latter case, perforations have to be made m the casing to allow production.
  • the method of treating a formation around a wellbore extending from a hydrocarbon-beanng zone comprises the steps of interrupting production from the hydrocarbon-beanng zone; introducing into the hydro- carbon-bearing zone a foam forming composition comprising a surfactant-in-oil solution; and resuming production from the hydrocarbon-beanng zone.
  • the gas and the foam forming composition will create a foam and maintain the foam.
  • This foam will reduce the gas permeability. Therefore in those parts of the hydrocarbon-beanng zone where the gas permeability is initially high, the foam will reduce it. And in parts of the zone where oil is produced, the foam cannot be formed.
  • An advantage of the present invention is that the foam forming composition does not contain water, because water would increase the water saturation of the formation which will have an adverse effect on the initial oil production.
  • the foam-forming composition does not contain gas, the pumping effort is low.
  • the oil used in the foam forming composition can be any hydrocarbon oil, however, suitably the crude oil that is produced is used.
  • the surfactant concentration in the solution s suitably between 0.5 and 5 per cent by volume.
  • the surfactant used is suitably a polymeric compound having good solubility in oil, but low (e.g., less than 1 %w, preferably less than 0.1 %w) or preferably no solubility in water (less than 0.01 %w) .
  • the molecular weight of the surfactant varies m the range of 5,000 to 20,000.
  • Non-ionic surfactants are preferred.
  • suitable surfactants include polyesters prepared from acrylates, methacrylates and other vinyl ethers, or siloxanes .
  • Examples of the first class of surfactants include fluoroaliphatic polyesters that contain fluoroacrylate derivates, such as FLUORAD FC-740 (trademark by 3 Industrial Chemical Products), or similar products from e.g. ATOFINA. Polymethyloctadecyl- siloxane, sold by United Chemicals Technologies as PS130, is an example of a suitable siloxane-based surfactant.
  • FLUORAD FC-740 trademark by 3 Industrial Chemical Products
  • PS130 is an example of a suitable siloxane-based surfactant.
  • the core sample was placed in a cell m order to perform core flooding experiments at a pressure of 115 bar (absolute) .
  • the core sample was first flooded with water, in order to measure the absolute permeability. Thereafter the core sample was flooded with a light crude oil to obtain a core sample with a connate water saturation filled with the crude oil. In all experiments nitrogen was used to simulate the hydrocarbon gas . In a first experiment (not according to the invention) the oil was displaced by nitrogen, wherein the core sample was kept at a temperature of 63 °C. After injecting at the conditions of the experiment a volume of nitrogen equal to 800 pore volumes, the measured relative gas permeability of the core sample was 0.27. The relative permeability is the ratio of the measured permeability to the absolute permeability.
  • the experiments are representative for underground conditions where oil is produced from a hydrocarbon- bearing zone in the presence of free gas . From the experiments can be concluded that the present invention provides a simple method of treating the formation so as to reduce the permeability of the formation to gas and in this way to reduce the amount of gas that is produced

Abstract

L'invention concerne un procédé de traitement d'une formation située autour d'un puits de forage partant d'une zone contenant des hydrocarbures. Ce procédé consiste à interrompre la production à partir de cette zone, à y introduire une composition moussante contenant une solution tensioactif/huile, puis à reprendre la production à partir de ladite zone.
