GRAVEL PACKING APPARATUS Filed June 27. 1960 INVENTOR.
.51 w;- 2 lglqwvs SSH/ELD JQ United States Patent 3,134,439 GRAVEL PACKING APPARATUS Wayne S. Shields, J12, Mosman Park, Western Australia, Australia, assignor to Gulf Oil Corporation, Pittsburgh, Pa., a corporation of Pennsylvania Filed June 27, 1969, Ser. No. 38,806 3 Claims. (Cl. 16651) This invention relates to gravel packing a liner in the borehole of a well and more particularly to a method and apparatus utilizing a single trip into a well for washing a liner into the borehole of the well to the desired depth and packing gravel in the space surrounding the liner.
A difiiculty frequently encountered in oil and gas wells in some areas is caused by the migration of sand from the formation into the wells. The sand may plug production tubing and either seriously reduce or completely prevent production from the well. In some high pressure formations, the sand may be carried at a high velocity by the fluids produced from the well and rapidly erode tubing, valves and other equipment in the well. Producing sands in some areas are so friable that sand can be washed from the perforated section of casing extending through the formation and in the time it takes to make a round trip to install production tubing, the perforations will again be covered with sand.
In order to combat the sanding of the wells it is a common practice to install slotted liners in the borehole through the producing formation and to pack sand around the outer surface of the liner. The conventional method of placing liners is to wash the formation sand out of the borehole with open ended tubing, place the calculated sand fill in position in the hole, and then pull the tubing. A slotted liner is then washed into place. This method of installing a liner made an extra trip into the hole necessary. Moreover, failures were often encountered immediately after placing the Well in production. The cause of the failure was suspected to be bridging of the gravel during the washing in of the liner which resulted in a nonuniform pack of sand around the liner.
This invention resides in a method and apparatus involving only a single trip into the well for washing a slotted liner into place through the formation sand in the borehole of a well, washing the formation sand from the borehole of the well while lowering the slotted liner to the desired location, breaking down the formation,
packing a gravel fill around the outer surface of the liner, squeezing gravel packed around the liner into the formation, and cleaning the sand from within the liner to put the well in condition for production.
In the drawings:
FIGURE 1 of the drawings is a vertical sectional view of the apparatus of this invention as it is washed into place through the formation sand.
FIGURE 2 is a vertical sectional view showing the apparatus in condition for washing sand from the liner after the liner has been set in place and gravel has been packed around it.
Referring to FIGURE 1 of the drawings, a lower section of a Well, indicated generally by reference numeral 10, is illustrated with casing 12 set through an incompetent producing formation 14. The casing 12 is perforated as indicated at 16 through the formation 14 to allow the formation fluids to flow into the well. Although this invention is illustrated in a well in which casing is set through the production formation 14, its use is not limited to such installations and can be used when production is through an open borehole. It is 3,134,439 Patented May 26,1954

Extending down through the casing 12 is a tubing string 18 of a diameter smaller than the diameter of casing 12 to provide an annulus between the tubing string 18 and the casing 12 through which liquids can be pumped. Connected in and forming part of the tubing string 18 is a cross-over 20 provided with opposed cup sealing means 22 adapted to prevent fiow either upwardly or downwardly between the outer surface of the upper cross-over 20 and the casing 12. Cross-over 20 is provided with upper ports 24 above the sealing means 22 to provide communication between the lower part of tubing string 18 beneath the sealing means 22 and the upper annulus 26 above the sealing means 22. Lower ports 28 are provided in the cross-over 2i) and communicate with a central conduit 36 which in combination with an upper end plate 32 within the cross-over 20 places the lower annulus 34 below sealing means 22 in communication with the upper portion of the tubing string 18.
A liner packer 36, diagrammatically illustrated in the drawings, is connected to the tubing string 18 through a suitable means such as a conventional setting tool. For example the portion of tubing string 18 below the crossover 20 may be a mandrel which can be backed out of the packer and the packer set by the weight of the tubing string. The packer 36 is connected to the upper end of a slotted liner 38 in the usual manner and is adapted to be set against Walls of casing 12 to close the annular space 40 surrounding the slotted liner after that space has been filled with gravel.
Extending down through the liner 38 from the lower end of the tubing string 18 is a wash pipe 54. Connected in and forming a part of the wash pipe 54 is a check valve assembly 56 adapted to allow flow from within the liner 38 into the wash pipe 54 but prevent flow from within the wash pipe 54 into the space Within the slotted liner 38. The check valve assembly illustrated in the drawings consists of a central sleeve 58 closed at its lower end and supported within a shell 60 by a plurality of inlet lines 62 which provide communication from outside of the shell 69 into the sleeve 58. A Valve cage 64 at the upper end of the sleeve 58 contains a balltype check valve 66 adapted to seat on a valve seat 68 when flow is downward through the wash pipe 54. A lower section 70 of the wash pipe 54 extends from the lower end of the check valve assembly 56 into the upper end of the passage 44. Seal rings 72 engage the walls of the passage and lower extension 70 to direct liquid discharged from the lower end of the wash pipe 54 downwardly through passage 44.
In the placing and gravel packing of liner 38 in the process of this invention, the apparatus is assembled at the well head as illustrated in FIGURE 1 and is lowered into the well on the lower end of the tubing string 18. When the liner reaches the formation sand fill in the borehole, a liquid is pumped down the well through the annulus 26 and enters the lower portion of the tubing string 18 through the port 24 in the cross-over 20. The
sealing means 22 engage the wall of the well, which in the structure illustrated in the drawings is the casing 18, to prevent flow around the cross-over 20. The liquid thenfiows down the wash pipe 54, through the lower section 76 and the passage 44, and out the lower end of the liner shoe 42. The liquid washes thesand from the casing upwardly around the liner 38 and into the lower ports 28 of the cross-over 26. The sand is carried upwardly from-the well through the upper portion of the tubing string 18. Washing is continued until the liquid discharged at the well head is clean.
The tubing stringlia is then loaded with a liquid, preferably oil, and the formation broken down by pumping the oil down the tubing with the outlet at the well head from the annulus 26 closed to prevent returns of oil to the well head. During this phase of the operation the fiow'is downward through the tubing string 18, outward through the lower ports 28 into the annulus 34, and then into the'formation through the perforations 16 in the casing 12. Gravel is added to the oil pumped down the tubing string .18 and the pumping continued with'n'o returns to the Well head thereby forcing the gravel and oil into the formation. The term gravel is used in this specificationto designate the solids introduced into the well and distinguish them from formation sands and not to designate. the size of the solid particles; The squeeze is continued at high casing pressures, for example about 2500 pounds per square inch, to pack the gravel around the casing 12.
After the squeeze is completed, the upper end of the annulus 26 is opened to allow circulation to the well head and the pumping of oil or other liquid containing gravel is continued to fill the annulus 49 between the liner 38 and the casing 12 with gravel. During this stage of the operation, the flow is downward through the tubing string 18, outward through lower ports 28 into the annulus 34, downward into the annulus 40 between the liner and the casing, inward through the slots of the liner 38 and through inlets 62, upward through the valve cage 64 in wash pipe 54, outward through upper ports 24 into the annulus 26, and then to the well head.
The filling of the annulus is continued until an increase in pressure indicates that the slots in the liner 38 have been covered with gravel. The tubing string is then released from the liner packer 36 and the liner packer set. Conventional apparatus for release of the tubing string from the packer and for setting the packer can be used. In the drawings such apparatus is represented diagrammatically by shear pin 74 connecting the lower end of the tubing string 18 to the liner packer 36 and a shoulder 76 on the outer surface of the lower end of the tubing string which allows the weight of the tubing string to be placed on the packer to set it against the casing 12 as indicated in FIGURE 2 of the drawings. The tubing string 18 is then lifted to raise the wash pipe 54 out of the passage 44. Liquid is then circulated down the annulus 26 through the upper port 24 into the wash pipe 54' and out the lower end of the wash pipe 54. The liquid returns up through the space within the liner into the lower ports 28 and into the upper portion of the tubing string 18. The circulation is continued until the returns at the surface are clear, which indicates that sand that may have passed through the liner has been removed from within the liner.
The apparatus of. this invention allows the liner to be washed into place and gravel packed in a single trip into the well. The check valve assembly 55 at the lower end of the Wash pipe 54, in combination with the check valve 46, directs flow out the lower end of the liner 33 during the washing in operation to permit the liner to be readily washed to the bottom of the hole. The check valve assembly 56 then allows the circulation necessary for cross-over filling of the annular space between the outer surface of the liner and the borehole wall or. the
casing.
