Definitions

  • the present invention relates to improved methods and apparatus for completing unconsolidated lateral well bores.
  • Lateral well bores i.e., well bores that are drilled horizontally or substantially in a horizontal direction from a vertical or substantially vertical primary well bore are often completed in unconsolidated formations containing loose and incompetent fines and sand which migrate with fluids produced from the formations.
  • the presence of formation fines and sand in the produced fluids is undesirable in that the particles abrade tubular goods, producing equipment, pumps and the like and reduce the fluid production capabilities of the formations.
  • completions utilizing gravel packs are often utilized.
  • a screen is placed in the well bore and positioned within the unconsolidated subterranean zone which is to be completed.
  • the screen is connected to a tool which includes a production packer and a crossover and the tool is in turn connected to a work or production pipe string.
  • a particulate material which is usually graded sand, often referred to in the art as gravel, is pumped in a slurry down the work or production pipe string and through the crossover whereby it flows into the annulus between the screen and the well bore.
  • the liquid forming the slurry leaks off into the subterranean zone and/or through the screen which is sized to prevent the gravel in the slurry from flowing therethrough.
  • the gravel is deposited in the annulus around the screen whereby it forms a gravel pack.
  • the size of the gravel in the gravel pack is selected such that it prevents formation fines and sand from flowing into the well bore with produced fluids.
  • Gravel packs have also been formed in well bores using slotted pipes.
  • the gravel is placed in the annulus between a slotted pipe and the walls of the well bore as well as within the pipe.
  • the gravel is usually coated with a hardenable resin composition which consolidates the gravel into a hard permeable pack. Thereafter, the gravel deposited within the slotted pipe can be drilled out of the slotted pipe or left in the slotted pipe as desired.
  • Gravel bridges have heretofore been prevented by utilizing a slotted pipe, i.e., a pipe with openings formed therein, with a sand screen disposed within the slotted pipe.
  • the gravel slurry is injected into the annulus between the slotted pipe and the walls of the well bore and between the slotted pipe and the sand screen. This arrangement allows the gravel slurry to flow around gravel bridges and deposit gravel in voids produced.
  • lateral well bores Another problem very often encountered in the completion of lateral well bores involves unequal production of formation fluids along the length of the lateral well bore.
  • Lateral well bores are utilized in subterranean formation producing zones to increase the area of well bore penetration in the subterranean zones to thereby increase hydrocarbon production.
  • the portion of a subterranean formation penetrated by the heel of a lateral well bore often experiences higher draw-down pressure than the portion of the well bore closest to the toe.
  • the term “heel” refers to the portion of the lateral well bore where the well bore begins its curvature to horizontal and the term “toe” refers to the end portion of the lateral well bore.
  • the present invention provides improved methods and apparatus for completing unconsolidated subterranean zones subject to migration of formation fines and sand with produced formation fluids penetrated by lateral well bores which meet the needs described above and overcome the deficiencies of the prior art.
  • the improved methods basically comprise the steps of placing a slotted pipe in the lateral well bore having openings formed therein through which produced formation fluids flow.
  • the openings vary in size or vary in the number of the openings along the length of the slotted pipe or both so that the produced formation fluids flow into the slotted pipe at substantially equal flow rates over the length of the slotted pipe.
  • the annulus between the slotted pipe and the well bore is isolated and particulate material is injected into the annulus whereby the particulate material is uniformly packed in the annulus and in the interior of the slotted pipe so that the migration of formation fines and sand with produced formation fluids is prevented.
  • the lateral well bore can be cased with perforations formed therein or completed open-hole and the particulate material is preferably graded sand.
  • the particulate material utilized is preferably coated with a hardenable resin composition which hardens and consolidates the particulate material into a hard permeable uniform mass. Once the hardenable resin has hardened whereby the particulate material is consolidated into a hard permeable pack in the annulus between the slotted pipe and the well bore as well as in the interior of the slotted pipe, at least a portion of the hard permeable mass within the interior of the slotted pipe can be drilled out if desired.
  • a slotted pipe is placed in the lateral well bore having openings formed therein through which the produced formation fluids flow and having an internal sand screen disposed therein.
  • the slotted pipe includes openings that vary in size or vary in the number of openings along the length of the slotted pipe or both so that the produced formation fluids flow into the slotted pipe at substantially equal flow rates over the length of the slotted pipe.
  • the annulus between the slotted pipe and the well bore and the annulus between the sand screen and the slotted pipe are isolated.
  • particulate material is injected into the annulus between the slotted pipe and the well bore and the annulus between the slotted pipe and the sand screen whereby the particulate material is uniformly packed in the annuluses and the migration of formation fines and sand with produced fluids is prevented.
  • FIG. 1 is a side cross-sectional view of a lateral open-hole well bore penetrating an unconsolidated subterranean producing zone having a slotted pipe, a production packer and a crossover connected to a production string disposed therein.
  • the drawing illustrates the placement of gravel between the well bore and the slotted pipe and between the slotted pipe and the sand screen.
  • FIG. 2 is a side cross-sectional view of the lateral well bore, the slotted pipe with an internal sand screen, the production packer and the cross-over of FIG. 1 after the gravel has been placed and produced fluids are flowing to the surface.
  • the present invention provides improved methods and apparatus for completing an unconsolidated subterranean zone subject to the migration of formation fines and sand penetrated by a lateral well bore having unequal produced formation fluid flow rates over the length of the well bore.
  • lateral well bore is used herein to mean the portion of a well bore in an unconsolidated subterranean producing zone to be completed which is substantially horizontal or at an angle from vertical in the range of from about 65° to about 105°.
  • the term “slotted pipe” is used herein to mean pipe which includes slots, holes or other shaped openings therein.
  • the improved apparatus of the present invention is illustrated disposed in an open hole lateral well bore 2 .
  • the lateral well bore 2 is illustrated extending into an unconsolidated subterranean zone 4 from a cased and cemented well bore 6 which extends to the surface.
  • a slotted pipe 8 having a plurality of openings 24 therein is disposed in the lateral well bore 2 whereby an annulus 22 is formed between the walls of the well bore 2 and the slotted pipe 8 .
  • a sand screen 10 is disposed within the slotted pipe 8 in a manner whereby an annulus 12 is formed between the slotted pipe 8 and the sand screen 10 .
  • FIG. 1 illustrates the operation of the apparatus of this invention when a slurry of particulate material is pumped into the annulus 12 between the slotted pipe 8 and the sand screen 10 and into the annulus 22 between the slotted pipe 8 and the walls of the well bore 2 .
  • FIG. 2 illustrates the apparatus of the invention after the particulate material 26 has been packed into the annuluses 12 and 22 and the well is returned to production.
  • the pack of particulate material 26 within the annuluses 12 and 22 filters out and prevents the migration of formation fines and sand with produced formation fluids that enter the well bore 2 from the unconsolidated subterranean zone 4 .
  • the removable cross-over 14 is a sub-assembly which allows fluids to follow a first flow pattern whereby particulate material suspended in a slurry can be packed in the annuluses 12 and 22 between the sand screen 10 and the slotted pipe 8 and between the slotted pipe 8 and the well bore 2 . That is, as shown by the arrows in FIG. 1, the particulate material suspension flows from inside the production or work string 16 into the annulus between the sand screen 10 and the slotted pipe 8 and into the annulus between the slotted pipe 8 and the well bore 2 by way of ports in the cross-over 14 .
  • fluid is allowed to flow from inside the sand screen 10 through the cross-over 14 to the other side of the packer 18 outside the production string.
  • flow through the cross-over 14 can be changed to a second flow pattern whereby fluid from inside the sand screen 10 flows directly into the production string.
  • the slotted pipe 8 includes a plurality of circular openings 24 formed therein through which the produced formation fluids flow.
  • the openings 24 are of varying sizes extending over the length of the slotted pipe 8 . That is, the openings 24 are small at the inlet end of the slotted pipe 8 adjacent to the heel portion of the well bore 2 (identified in the drawings by the numeral 30 ) and increase in size over the length of the slotted pipe to the toe portion of the well bore (identified in the drawings by the numeral 32 ).
  • the openings 24 can be of varying size over the length of the slotted pipe 8 as shown in the drawings or the openings 24 can be of the same size over the length of the slotted pipe 8 with the number of openings increasing or otherwise varying over the length of the slotted pipe 8 .
  • the required sizes of the openings 24 or the number of the same size openings 24 allocated over the length of the slotted pipe 8 is determined by production tests conducted in the lateral well bore prior to the placement of the slotted pipe 8 and related apparatus in the well bore or by estimation of the pressure drop from the heel of the well bore to the toe of the well bore.
  • the sizes and/or number of openings required in the slotted pipe 8 to produce substantially equal flow rates of produced fluids into the slotted pipe 8 over its length are determined.
  • a slotted pipe 8 with those openings is then placed in the lateral well bore along with the other apparatus required.
  • the methods of the present invention for completing the well bore 2 in the unconsolidated subterranean zone 4 are as follows.
  • the slotted pipe 8 containing the openings 24 required to produce equal produced fluid flow over the length of the slotted pipe 8 with the sand screen 10 therein is placed in the well bore 2 .
  • the sand screen can be omitted if the procedure described above is utilized whereby the particulate material placed in the well bore is consolidated into a permeable pack or is otherwise prevented from flowing out of the well bore with produced formation fluids.
  • the annulus 22 between the slotted pipe 8 and the walls of the well bore 2 as well as the annulus between the sand screen 10 and the slotted pipe 8 are isolated by setting the packer 18 . Thereafter, a slurry of particulate material is injected into the annulus 12 between the sand screen 10 and the slotted pipe 8 and into the annulus 22 between the walls of the well bore 2 and the slotted pipe 8 . Because the particulate material slurry is free to flow through the openings 24 as well as the open end of the slotted pipe 8 , the particulate material is uniformly packed into the annulus 22 between the well bore 2 and slotted pipe 8 and into the annulus 12 between the sand screen 10 and the slotted pipe 8 .
  • the pack of particulate material 26 formed filters out and prevents the migration of formation fines and sand with fluids produced into the well bore 2 from the subterranean zone 4 .
  • the methods and apparatus of this invention are particularly suitable and beneficial in forming gravel packs in long-interval lateral wells without the formation of sand bridges.
  • the particulate gravel material utilized in accordance with the present invention is generally of a size such that formation fines and sand that migrate with produced fluids are prevented from being produced.
