Definitions

  • Oil and gas well are drilled to a depth in order to intersect a series of formations or zones which produce hydrocarbons.
  • the drilled wells are cased with steel casing pipe and cemented to secure the casing in place.
  • the steel and cement barrier needs to be first perforated with shaped explosive charges prior to fracturing the surrounding oil or gas reservoir.
  • frac plugs can also be pumped down the well on an electric wireline, either by itself or in combination with the perforating gun assemblies.
  • frac fluids and/or sand are pumped down to the perforations and into the reservoir to stimulate movement of the oil or gas.
  • Use of the temporary plug prevents contamination of the already fractured levels below.
  • Coil tubing or jointed pipe intervention to mill out and remove the plugs on extended reach wells is extremely costly, unpredictable and sometimes impossible due to metal to metal friction encountered sliding in the casing, creating what is known as coil tubing lock-up.
  • frac plugs that are not reachable due to friction lock up issues are left in the well (i.e., not milled out) and intervals left behind these frac plugs are expected to flow through a 3 ⁇ 4 inch hole in the center of the frac plugs. Flow can sometimes be restricted by the number of frac plugs which were not accessible for mill-out due to the friction lock encountered.
  • the inner diameter of the cylindrical tube is sufficient to allow relatively unrestricted flow of oil or gas there through. In one embodiment, the inner diameter is greater than about 1 inch. In one embodiment, the inner diameter is about 2 inches and larger.
  • the inner diameter of the cylindrical tube is greater than 1/4 inches. In another embodiment, the inner diameter of the cylindrical tube is greater than 1 inch. In another embodiment, the inner diameter of the cylindrical tube is greater than 2 inches. In one embodiment, the cylindrical tube has at least one flow port located at a lower end of the cylindrical tube.
  • FIG. 1 is a cross-sectional view of an exemplary embodiment of the pumpable seat assembly.
  • the present invention relates generally to a process for fracturing, stimulating and producing a wellbore without having to mill out and remove fracturing/bridge plugs and to a pumpable seat assembly for use therein.
  • FIG. 1 shows one embodiment of a pumpable seat assembly ( 10 ) useful in the present invention, which assembly ( 10 ) is shown being set within a wellbore casing ( 12 ).
  • Pumpable seat assembly ( 10 ) comprises a generally cylindrical tube ( 14 ) having an upper end ( 15 ) and a lower end ( 17 ). Situated near the first end ( 15 ) of cylindrical tube ( 14 ) is an upper slip assembly ( 18 ) and situated near the lower end ( 17 ) of cylindrical tube ( 14 ) is a lower slip assembly ( 22 ).
  • Both the upper and lower slip assemblies generally include a plurality of serrations ( 23 ) which engage the casing ( 12 ) and prevent longitudinal movement of the slips ( 18 ) and ( 22 ) once set.
  • An elastomeric packer element ( 20 ) is mounted on the cylindrical tube ( 14 ) between the upper slip (( 18 ) and the lower slip ( 22 ).
  • the packing element ( 20 ) is adapted to be deformed into sealing engagement with the casing ( 12 ) upon compression of setting components (not shown).
  • the packing element ( 60 ) is shown and described as being one-piece it is to be understood that a packing element having multiple members is contemplated under the present invention. In either case, the packing element ( 20 ) is adapted to provide a fluid-tight seal between the cylindrical tube ( 14 ) and the casing ( 12 ).
  • biodegradable balls that may be used in the present invention is BioBalls soluble ball sealers available from Santrol of Texas. It is understood that other oil field service providers can also supply dissolvable products.
  • dissolvable balls can include biodegradable balls that can degrade over a period of hours or days when exposed to a set of predetermined environmental conditions.
  • the environmental conditions can include normal wellbore operating conditions of temperature and pressure at a particular depth or elevation in the wellbore, as well as the normal chemistry for drilling mud or pumping/frac fluids used during completion operations.
