Definitions

  • the invention relates to a method for induced fracturing in a subsurface formation.
  • the traditional water-based fracturing fluids generally can comprise any combination of slickwater, gelled polymer, crosslinkers and gelled LPG mixed with proppants and chemical additives.
  • a method of induced fracturing of a subsurface formation comprising sequentially injecting at least partly liquefied inert fluid slugs into different parts of the formation.
  • the formation may comprise a hydrocarbon fluid, such as a natural gas containing tight gas formation, a shale gas formation or a Coal Bed Methane (CBM) containing formation, or any other type of hydrocarbon containing formation
  • the liquefied inert fluid slugs may comprise at least one of the following inert fluids: Nitrogen(N 2 ), Carbon Dioxide (CO 2 ), Helium(He) and Liquefied Natural Gas(LNG) and each inert fluid slug may be injected in continuous or non continuous manner and comprise such an amount of inert fluid that at least a section of the formation into which the slug is injected suffers a thermal differential such that it thereby contracts.
  • This formation will subsequently reheat the initial inert fluid slug at least partly evaporating and expanding the gas and thereby generating further induced fractures in the formation.
  • a subsequent inert slug may be injected into a second section of the formation, which is located adjacent to the first section and the time interval between injecting the initial and subsequent slugs may be selected such that, at the time when the subsequent inert fluid slug is injected into the second part of the formation and induces at least part of the second section to again suffer a thermal differential and contract, the first section has been heated up by the surrounding formation to such a temperature that the initial inert fluid slug at least partly evaporates and expands and thereby generates further induced fractures in the first section of the formation, wherein the simultaneous expansion of the first section and contraction of the second section enhances the fracturing process.
  • Figure 1 depicts a schematic three-dimensional view of a subsurface formation 10 having a substantially horizontal upper and lower boundaries 10A and 10B, which formation 10 is penetrated by substantially horizontal segmented lower sections 1A-D,... , 6A-6D of six inert fluid injection wells 1-6.
  • Each well 1-6 comprises a segmented lower section 1A-1D, ..., 6A-6D that is divided by valves or other isolation devices into four segments A-D.
  • valves or other isolation devices sequentially permit injection of an at least partly liquefied inert fluid slug comprising Nitrogen, Carbon Dioxide, Helium and/or Liquefied Natural Gas (LNG) in a continuous or non continuous manner through one or more well segments 1A-D,... ,6A-6D, which have perforations that permit fluid to liquefied inert fluid to flow into and thereby initially freeze and contract and to subsequently evaporate and expand in the surrounding formation 10, wherein the contraction and subsequent expansion enhances the induced fracturing process without requiring added chemicals.
  • LNG Liquefied Natural Gas
  • a suitable sequence of opening and closing well segments is 2D->1D, 1D->2C, 2C->1C, 1C->2B, 2B->1B, 1B->2A, 2A->1A, 1A->3D, 3D->2D, 2D->3C, 3C->2C, 2C->3B, 3B->2B, 2B->3A, 3A->2A, 2A->4D, 4D->3D, 3D->4C, 4C->3C, 3C->4B, 4B->3B, 3B->4A, 4A->3A, 3A->5D, ... until each of the infinitive number of horizontal well segments has been opened and subsequently closed.
  • inert fluid injection wells 1-6 which each have four substantially horizontal segmented lower section 1A-D,..., 6A-6D as shown in Figure 1 any other number of inert fluid injection wells and any other number (n) of segmented lower sections and valves or other isolation devices may be used.
  • Figure 2 is a cross-sectional view of a tight gas, shale gas or Coal Bed Methane(CBM) containing formation 10, or any other type of hydrocarbons containing formation having an substantially horizontal upper and lower boundaries 10A and 10B, which formation is penetrated by horizontal lower sections 11-20 of nine inert fluid injection wells.
  • CBM Coal Bed Methane
  • the lower sections 11-20 are staggered, such that the lower sections 12, 14, 16, 18 and 20 are located closer to the upper boundary 10A than to the lower boundary 10B, whereas the lower sections 11, 13, 15, 17 and 19 are located closer to the lower boundary 10B than to the upper boundary 10A.
  • Figure 3 is a schematic top view of the formation 10 of Figure 2 which shows the lower sections of five wells 12-16 out of the series of nine wells 11-20 shown in Figure 2 .
  • Each of these lower sections comprises a suitable number of segments A,B,C,.. Z, etc., wherein the number may be in the order of tens or hundreds that are separated by valves and/or other isolation devices.
  • the staggered arrangement of the lower sections of the inert fluid injection wells 11-20 shown in Figures 2 and 3 further enhances the induced fracturing process, so that the formation 10 can be induce fractured by physical and thermodynamic effects initiated by the initial contraction and subsequent expansion of the inert fluids and formation 10 and the induced fracturing associated with the injection of cold substantially liquid inert fluid, which then evaporates in the pores of the formation 10 thereby inducing fracturing in the formation 10 without requiring any or any substantial amount of additional chemicals that could lead to potential causes of pollution of aquifers adjacent to formation 10 and/or the inert fluid injection wells 1-6 and 11-20.
