Definitions

  • the invention disclosed and claimed in this application relates to the treatment of oil and/or gas wells.
  • One example of such treatment is commonly referred to as fracturing the formulation around an oil or gas well.
  • Fluid with certain chemical additives and a proppant are injected into the formation surrounding either a vertical or horizontal well to form cracks or passageways in the formation to stimulate the production of the well.
  • U.S. Patent Number 7,322,417 discloses a plurality of vertically spaced production layers 1 and a plurality of valves 14. A ball is captured on a valve seat 94 which will cause an increase in pressure to open valve 14. This allows fracturing fluids to enter the annular region that surrounds the valve.
  • the balls may be formed of a dissolvable or frangible material, which allows the ball to be dissolved or eroded to open up communication upstream through the casing.
  • U.S. Patent Number 7,134,505 discloses a similar system in which a plurality of spaced apart packers 20 a-n and a plurality of valve bodies 26 c-n that capture balls of varying diameters to selectively open ports 16 c-e to allow fracturing fluids to flow into the isolated zones.
  • Stage frac methods include the use of pump down bridge plugs, perforating guns, and sliding sleeves. The current pump down method requires a drill out phase after frac with coiled tubing or jointed pipe. This is an expensive and time consuming process which involves additional risk of the coil tubing getting stuck in the wellbore. This time and operational risk is a significant impact item on the overall economics of oil and gas projects.
  • An expansible valve seat or stop member that can be run on wireline (pump-down, tractor, tubing or coiled tubing) is positioned at predetermined locations along the production casing and is expanded for example by a shaped charge or with a mandrel extrusion process.
  • a disintegrating or dissolvable ball can be dropped in the valve seat to isolate a portion of the well to allow for fracturing of the isolated portions of the well.
  • the seat may be made of the same material as the ball so that the drill out step is completely eliminated. Alternately, the valve seat may be mechanically captured by the production casing.
  • the ball and valve seat become the frac plug that would normally be pumped down in a conventional horizontal pump-down process.
  • the production casing can be perforated as in the pump down method and fracing can be initiated once the ball seals on the valve seat.
  • a dart may be used in lieu of a ball.
  • Balls, darts, seats or sleeves may be soluble, dissolvable or frangible.
  • FIG. 1 is a flow diagram of the process according to an embodiment of the invention.
  • FIG. 2 is a cross sectional view of expansible sleeve seat according to an embodiment of the invention.
  • FIG. 3 is a cross sectional view of the sleeve seat deployed within the production casing with the ball.
  • FIG. 4 is a cross sectional view of a second expansible sleeve seat and a dart.
  • FIG. 5 is a cross sectional view of a third expansible sleeve seat and a ball.
  • FIG. 6 is a cross sectional view of a fourth embodiment with an expansible sleeve and separate seat with a dart.
  • FIG. 7 is a cross sectional view of a fifth embodiment of the invention.
  • FIG. 8 is an end view of the embodiment of FIG. 7.
  • FIG. 9 is a cross sectional view of a sixth embodiment of the invention.
  • FIG. 10 is a cross sectional view of a further embodiment of the invention.
  • FIG. 11 is a cross sectional view of yet a further embodiment of the invention.
  • FIG. 12 is a cross sectional view of an embodiment of a connector sub.
  • the invention of this application is directed to a novel process of fracturing a plurality of zones in the formation surrounding a horizontal or vertical well without the use of multiple bridge plugs or frac plugs that require drill out after the fracturing process is complete prior to the production stage.
  • an expansible sleeve such as shown in FIG. 2 is placed at the desired location within the casing (83).
  • the expansible sleeve 10 consists of a relatively thin walled cylindrical tube 11 formed of a high tensile strength material similar to that of the production casing 21.
  • a ring of expansible material 12 may surround a portion of tube 11.
  • a cap 15 is positioned over the downhole end 16 of the tube so that the expansible sleeve 10 may be pumped into the well.
  • the outside diameter of the ring 12 is slightly less that the inside diameter of the casing.
  • Detonation cord 14 is wound about a frangible mandrel 13 positioned within the tube and includes an electrical cord 17 for detonation.
  • Another embodiment of this invention may employ the use of an extrusion process using a mandrel and sleeve to create the seat as shown in FIG. 3. The resultant sleeve or seat installed in the production casing will be the same whether the installation process is expansive or extruded.
  • Expansible sleeve 10 may be precisely positioned within the production casing by any suitable known technique such as a line counter or collar locator. Once positioned within the desired location of the production casing, the cord is detonated (84) causing the sleeve to expand outwardly against the inner surface of the casing (21). In so doing, the sleeve forms a seat 12 as shown in FIG. 3 which is capable of catching and retaining a ball or dart as shown in FIG. 3 and FIG. 4 that is pumped down (86).
  • the outer surface of tube 11 may be impregnated with a thin strip of no slip high strength metallic material.
  • the production casing and cement (if present) in the first frac zone can be perforated (85) in the conventional way by a perforating gun on the same tool-string as the expansible sleeve.
  • the tool-string can be removed, and the fracing process can be initiated by pumping down (86) a ball or dart to rest against seat 12. This will prevent the fracing fluid from flowing downhole and will cause the fracing fluid under pressure (87) to enter the formation surrounding the perforations in the production casing and thus commence the fracing process.
  • a second expansible sleeve can be placed (88) to isolate a second zone and the process can be repeated (88-92) for as many zones as desired as indicated in FIG. 1.
  • the ball, dart, seat or sleeve may be made of a soluble, dissolvable, or frangible material such that it would not be necessary to drillout the sealing mechanism after fracturing.
  • the ball, dart, seat or sleeve would shrink in size or completely dissolve so that the constituents went into solution or were flowed back with the frac load water.
  • FIG. 5 Another embodiment of the expansible sleeve is illustrated in FIG. 5.
  • a tubular member is shown in an unexpanded condition at 45.
  • Chevron or swellable seals 43 are positioned about an uphole portion 44 of the sleeve 45.
  • Sleeve portion 45 is expanded by a mandrel or shaped charge into the position indicated at 46 against the inner surface of the casing 21.
  • the uphole portion 44 of the sleeve may have a beveled surface (47) against which ball 22 rests when a ball or dart is pumped down into the casing.
  • FIG. 6 An additional embodiment of the expansible sleeve is illustrated in FIG. 6.
  • a sleeve 11 is expanded in the production casing 21 and used as a stop or no-go for a secondary conical seat 51 that is either simultaneously or subsequently placed on the no-go.
  • the perforations are then added.
  • a ball or dart 32 is then landed on the seat forming the sealing mechanism for the wellbore and the stage is frac'd.
  • Secondary seat 51 may have an elastomeric annular seat 52 that engages a tapered portion 53 of the sleeve 11 to form a seal. This process can be repeated as many times as necessary to adequately stimulate the formation surrounding the wellbore.
  • the ball, dart or seat in this embodiment may also be made of a soluble, dissolvable, or frangible material.
  • an expandable sleeve 10 is positioned and expanded within production casing 21 so that cylindrical tube 11 is secured to the casing.
  • a cage member 65 having a ball 66 is then pumped down to a position where it rests on shoulder 53 of tube 11 as shown in FIG. 7.
  • Cage member 65 has a hollow cylindrical portion 62 of slightly less diameter than the internal diameter of casing 21.
  • Cage member also has a hollow frustoconical portion 61 which terminates in an outlet 68.
  • a perforated disk 64 having perforations 63 closes one end of the cage as shown in FIG. 7.
  • Disk 63 includes an annular wall portion 67 which spaces ball 65 from disk 64.
  • the diameter of ball 63 is smaller than the inside diameter of cylindrical portion 62 of cage 65 so that fluid can flow from right to left, looking at FIG. 7, around ball 65 and through apertures 63.
  • cage 65 will prevent fluid flow from left to right as in fracing operations by virtue of ball 66 resting on frustoconical portion 61 of the cage.
  • the sleeve 11, cage member 62 and ball 66 may be made of a soluble, dissolvable or frangible material so that it would not be necessary to drill out the sealing mechanism after fracing.
  • FIG. 9 Another embodiment of the invention is illustrated in FIG. 9. This embodiment also utilizes a cylindrical tube 11 that has been expanded so to be secured within casing 21.
  • a solid frustoconical plug 71 after being pumped down into the well, rests against shoulder 53 of tube 11 at 72 as shown in FIG. 9 to prevent flow downhole of the plug 71.
  • Plug 71 may also be made of a soluble, dissolvable or frangible material.
  • the expandable sleeve may be formed of steel for example J-55 or similar steel.
  • the wall thickness may vary from approximately 0.095 inches to about 0.25 inches.
  • the diameter of the sleeve is selected to be slightly smaller than that of the production casing so for example if the casing is 5 1 ⁇ 2 inch casing, the sleeve may have an outside diameter of 4.5 inches.
  • FIG. 10 A further embodiment of a tool suitable for use according to the invention is shown in FIG. 10.
  • the tool 100 includes a hollow cone shaped sleeve 103 having an end portion having an outlet 119 formed therein.
