Definitions

  • the field of this invention relates to techniques and equipment to gravel-pack and treat closely spaced zones and more particularly in applications where some degree of isolation is desired between the zones for production.
  • a screen is lowered into the wellbore on a work string and is positioned adjacent to the subterranean formation to be completed, e.g., a production formation.
  • Particulate material collectively referred to as "gravel”
  • a carrier fluid is then pumped as a slurry down the work string where it exits through a "cross-over" into the well annulus formed between the screen and the well casing or open hole, as the case may be.
  • the carder liquid in the slurry normally flows into the formation and/or through the screen itself, which, in turn, is sized to prevent flow of gravel therethrough.
  • the gravel in turn, is sized so that it forms a permeable mass which allows the flow of the produced fluids therethrough and into the screen while blocking the flow of the particulates produced with the production fluids.
  • alternate path well strings have been developed which provide for distribution of gravel throughout the entire completion interval, even if sand bridges form before all the gravel has been placed.
  • Some examples of such screens include U.S. Patents 4,945,991; 5,082,052; 5,113,935; 5,417,284; 5,419,394; 5,476,143; 5,341,880; and 5,515,915.
  • the alternate paths e.g., perforated shunts or bypass conduits
  • the alternate paths extend along the length of the screen and are in fluid communication with the gravel slurry as the slurry enters the well annulus around the screen. If a sand bridge forms in the annulus, the slurry is still free to flow through the conduits and out into the annulus through the perforations in the conduits to complete the filling of the annulus above and/or below the sand bridge.
  • the objective of the apparatus and method of the present invention is to facilitate fluid treatments such as fracture stimulation, as well as gravel-packing, simultaneously, in two or more adjacent producing zones.
  • Another object of the method and apparatus of the present invention is to provide limited hydraulic isolation between two or more adjacent zones.
  • Yet another object of the present invention is to minimize rig time for the completion by reducing the number of trips required to install the gravel screen assemblies and to treat the formation.
  • a completion assembly facilitates gravel-packing and fracture stimulation of closely spaced zones.
  • the assembly includes a pair of spaced screens with a production packer in between.
  • the production packer has a short bypass flowpath therethrough to allow fluids carrying the gravel to pass the production packer so that the upper and lower zones can be gravel-packed simultaneously, as well as fracture-stimulated simultaneously. Thereafter, the presence of the gravel in the bypass tube in the packer between the zones provides some limited isolation based on the permeability of the gravel found in the bypass passage and the pressure drop across that passage. Production then can follow from the lower zone, the upper zone, or both zones depending on the completion configuration.
  • Figure 1 illustrates the assembly as installed, ready to gravel-pack and fracture- stimulate.
  • Figure 2 is a detail of one of the components in the assembly of Figure 2, shown by - circle 2, illustrating the communication through the production packer to facilitate gravel- packing and fracture-stimulation of two zones simultaneously.
  • FIG. 1 two closely spaced formations 10 and 12 are illustrated.
  • the formations 10 and 12 are closely spaced in the order of 5-20 ft.
  • Figure 1 illustrates that the bridge plug 14 has been set in the casing 16.
  • the casing 16 has been perforated as indicated by perforations 18 and 20 which are, respectively, in zones 12 and 10. Subsequent to perforation, should it be necessary, a cleanout trip can be made to clean the wellbore before installing the assembly illustrated in Figure 1.
  • the production packer 22 is run-in to the desired depth and set.
  • a Baker Oil Tools-type FN-1 packer is used.
  • the packer 22 has a seal bore 24. Inserted into seal bore 24 is a parallel flow tube 26 shown in more detail in Figure 2.
  • the preferred embodiment includes the use of a Model N, fully opening parallel flow tube made by Baker Oil Tools.
  • Figure 2 indicates that the flow tube 26 has opposed chevron seals 28 and 30 which contact the seal bore 24 of the production packer 22.
  • N main flow tube 32 extends parallel to a bypass tube 34.
  • the main flow tube 32 is connected at its lower end to a section of blank pipe 36, which in turn supports the lower screen 38.
  • a Baker Weld 140 Screen made by Baker Hughes Inteq can be used.
  • An upper screen 40 is preferably made of the same construction as the lower screen 38 and is disposed adjacent the perforations 20. Screen 38 is disposed adjacent perforations 18.
  • a seal bore receptacle 42 Mounted below the screen 40 is a seal bore receptacle 42.
  • Screen 40 has a locator seal assembly 44 which engages the seal bore receptacle 42.
  • Above screen 40 is a blank pipe 48, and on top of that is a shear-out safety joint 50.
  • a gravel-pack cross-over 52 Connected to the shear-out safety joint 50 is a gravel-pack cross-over 52, preferably a Model CK made by Baker Oil Tools.
  • Attached to the cross-over 52 is a gravel-pack packer 54. The assembly is run in the hole to the position shown in Figure 1 and the packer 54 is set and tested. This is done using the Standard Crossover Tool/Service Tool configuration.
  • the bypass tube 34 can have a spring-biased flapper 66 which opens upon higher pressures uphole against the bias of a torsion spring in a manner well- known in the art.
  • a spring-biased flapper 66 which opens upon higher pressures uphole against the bias of a torsion spring in a manner well- known in the art.
  • gravel-packing and fracturing can occur in separate but closely spaced zones using the assembly shown in Figure 1.
  • the pressures and flow rates are incrementally increased so that ultimately both zones 10 and 12 are properly fractured or treated.
  • the use of the short bypass tube 34 ensures that the pressure drop across the parallel flow tube 26 is minimal. This allows the achievement of sufficiently high flow rates into zone 12 to properly fracture it.
  • wash pipes can be used internally to the screens 40 and 38, and carrier fluid type and travel concentration can be selected, to facilitate the proper deposition of the gravel 64, particularly around screen 38. Any return fluids to the surface come up internally through the screens 38 and 40 and back through the cross-over 52 in a manner well-known in the art.
  • a production string 56 is run-in from the surface and internally to the screen 40, which also includes a sliding sleeve valve 46, preferably of the CM-type made by Baker Oil Tools. Production from either or both zones can begin.
  • the lower zone 12 can be produced by keeping the sliding sleeve valve 46 in a closed position. It should be noted that at the conclusion of the gravel-packing, the entire annulus 60 is full, including the bypass tube 34. Thus, the presence of gravel throughout tends to reduce migration from formation 10 down to formation 12 when formation 12 is being produced.
  • a plug can be run down to the seal bore receptacle 42 to isolate zone 12 so that zone 10 can be produced after the sliding sleeve valve 46 is opened.
  • Other techniques may be used for producing either zone 10 or 12 which are known to those skilled in the art.
  • the completion assembly thus illustrated in Figures 1 and 2 provides minimal resistance to flow between two closely spaced zones so as to allow the appropriate flows and pressures to properly fracture two zones simultaneously while gravel-packing them.
  • a very short bypass tube 34 located in the production packer 22 is the sole significant resistance to flow between the zones for the purposes of treatment or fracturing.
  • a flapper 66 is pushed out of the flowpath so as to provide minimal resistance to flow in the fully open position.
  • some level of isolation between the zones 10 and 12 is achieved as the annulus 60, including the area between screens 40 and 38, is packed with gravel 64. While the isolation is not perfect, it is the best that can be obtained under the circumstances while attempting to achieve the objective of gravel-packing screens in adjacent zones while treating or fracturing at the same time.

Abstract

L'invention concerne un dispositif de complétion facilitant le gravillonnage et la stimulation de rupture de zones étroitement espacées. Ce dispositif comporte un couple de crépines espacées, un packer de production étant disposé entre ces crépines. Un écoulement de dérivation court est disposé dans le packer de production pour permettre aux fluides portant les graviers de passer au travers du packer de production de manière à effectuer simultanément le gravillonnage et la stimulation de rupture des zones supérieures et inférieures. Ensuite, la présence de graviers dans le tube de dérivation du packer disposé entre lesdites zones produit une isolation limitée du fait de la perméabilité des graviers dans le tube de dérivation, et de la chute de pression au travers de ce tube. La production peut alors être effectuée à partir de la zone inférieure, de la zone supérieure, ou des deux zones en fonction de la configuration de complétion.
