Description
- Conventional systems for treatment of earth formations, such as acidizing, in downhole industries typically employ coiled tubing. Coiled tubing is run into a borehole and treatment is performed on one zone of the formation at a time. After treatment of a zone is completed the coiled tubing is moved to align with the next zone and the process is repeated until all desired zones have been treated. This process is time consuming because of the serial nature. Additionally, coiled tubing is unable to reach the toe of wells with long horizontal or highly deviated sections. The maximum flow rate through the coiled tubing is limited because of the flow area available. As such, industry is receptive to new systems and methods that alleviate any of the foregoing concerns.
- Disclosed herein is a method of treating a formation. The method includes, running a first string having at least one first port into a completion string having a plurality of second ports, flowing treating fluid through the first string, and flowing treating fluid through the at least one first port and through at least one of the plurality of second ports and into the formation.
- Further disclosed herein is a treatment and completion system. The system includes, a completion string positioned within a borehole in an earth formation, a first string runnable within the completion string, having a plurality of first ports distributed along the first string that are configured to be in fluidic communication with a plurality of second ports along the completion string. The plurality of first ports are independently settable to a different flow restriction, and a plurality of seals distributed along the first string or the completion string are configured to seal to the other of the first string and the completion string to isolate the plurality of first ports from one another such that treating fluid can be pumped through the first string and through the plurality of first ports and through the plurality of second ports to treat a plurality of zones of a formation simultaneously.
- The following descriptions should not be considered limiting in any way. With reference to the accompanying drawings, like elements are numbered alike:
-
FIG. 1 depicts a schematic of a treating system disclosed herein; and -
FIG. 2 depicts a schematic of an alternate treating system disclosed herein. - A detailed description of one or more embodiments of the disclosed apparatus and method are presented herein by way of exemplification and not limitation with reference to the Figures.
- Referring to
FIG. 1 , an embodiment of a treating system disclosed herein is illustrated at 10. The treatingsystem 10 includes afirst string 14 referred to herein is a treating string that is runnable within acompletion string 18. The treatingstring 14 includes a plurality offirst ports 22 referred to herein as treating ports that are distributed along the treatingstring 14. The treatingports 22 are configured to be in fluidic communication withsecond ports 26 that are distributed along thecompletion string 18. Each of the plurality of treatingports 22 is independently settable to a different flow restriction level. Theports ports 22 can also include flow control devices that include restrictors such as annular tortuous flow paths like mazes and helical flow paths, for example. They can also include movable portions such as sleeves to alter restriction of flow therethrough including completely closing flow through one or more of theports seals 30 are distributed along the treatingstring 14 or thecompletion string 18 and are configured to seal to thecompletion string 18. Sealing of theseals 30 isolates each of the plurality of treatingports 22 from one another within thecompletion string 18. Similarly,seals 32, such as packers, for example, sealingly engage between thecompletion string 18 and aborehole 50 within anearth formation 38 thereby creatingseparate zones 34 along theborehole 50. Theseals 38 may be aligned with theseals 30 to allow an operator to control flow of fluid throughspecific ports 22 and throughspecific ports 26 and into theformation 38 simultaneously. The foregoing structure allows for greater control of injection flow rates along theborehole 50 than is permitted with conventional systems. - The treating
system 10 allows for customization of flow restriction through each of the treatingports 22 along the treatingstring 18. These adjustments can be configured to account for various characteristics and differences between thezones 34. These differences can be due to variations in permeability between thedifferent zones 34, for example. They can also be due to where along the completion string 18 (i.e. relative locations along the completion string 18) each of the treatingports 22 will be located. Flow restriction of the treatingports 22 near aheal 42 of thecompletion string 18 will likely need to be set at a higher flow restriction level than the treatingports 22 near atoe 46 of thecompletion string 18 to balance flow of treating fluid between thezones 34 near theheal 42 with thezones 34 near thetoe 46. - The treating
string 14, unlike conventional treating systems that employ coiled tubing, uses sections of pipe that are connected together in an end-to-end fashion. As such, the treatingstring 14 can be run through a full length of thecompletion string 18 regardless of how highly deviated thecompletion string 18 may be, including when the deviated portion of thecompletion string 18 is completely horizontal. - Additionally, the inner diameter that defines a flow area through the treating
string 14 can be significantly larger than conventional coiled tubing treating lines. As such, treating fluids, such as acid for acidizing theformation 38, for example, can be injected at higher flow rates. These higher flow rates can be beneficial when treating fluid needs to be pumped deep into one or more of thezones 34 including those that have low permeability or are far from the heal. The high flow rates possible allow for treating a plurality of thezones 34 simultaneously, up to and including all thezones 34 along theborehole 50. - In addition to the treating
ports 22 being independently customized for flow restriction to the specific desired needs of thezones 34 that will be treated via the treatingports 22, the treatingports 22 can work together in pairs with thesecond ports 26. Knowing specific distinctive features aboutsecond ports 26 allows an operator to customize the treatingports 22 to work in concert with the second-ports 26. This is helpful since some or all of thesecond ports 26 may be simply slotted openings in a base pipe (as in the present embodiment). In a hydrocarbon recovery application, for example, after injecting a treating fluid, the treatingstring 14 may be left in place during production of hydrocarbons. In this embodiment employing inflow control devices as theports 22 can allow for more complete emptying of hydrocarbon from all of thezones 34 than would occur without theinflow control devices 22 being present. Additionally, the inflow control devices delay water breakthrough in highlypermeable zones 34 that would likely produce water much earlier if theinflow control devices 22 were not present. Alternately the treatingstring 14 can be removed from thecompletion string 18 and hydrocarbons produced through thecompletion string 18 alone. In yet another embodiment a third string (not shown) could be run into thecompletion string 18 and production carried out through both thecompletion string 18 and the third string. - In one embodiment of the treating
system 10 the flow restriction levels of the treatingports 22 are adjustable after being run into thecompletion string 18.Control lines 54 in operable communication withactuators 58 at each of the treatingports 22 can adjust the flow restriction of each of the treatingports 22 as desired in real time. This real time adjustment can include completely closing of the treatingports 22 to thereby allow operators to alter flow rates as well as the total amount of treating fluid supplied to theparticular zones 34. - Referring to
FIG. 2 , an alternate embodiment of a treating system disclosed herein is illustrated at 110. The treatingsystem 110 differs from thesystem 10 in that instead of treating all of thezones 34 simultaneously, only a subset of the full number of thezones 34 is treated at one time. In the embodiment illustrated three of thezones 34 are treated at one time, although any number of thezones 34 could be included in a subset in an alternate embodiment. As illustrated, the first threezones 34 being treated are those nearest thetoe 46. After this first treatment is completed a treatingstring 114 employed within thecompletion string 18 is moved toward theheal 42 to align three treatingports 122 thereon with the next threesecond ports 26 and treating fluid is supplied therethrough. This is repeated until all of thezones 34 have been treated. - The
system 110 uses just twoseals 130, one on either side of the twoouter-most treating ports 122. Although embodiments can use one of theseals 130 between any of the treatingports 122 as each application dictates. - While the invention has been described with reference to an exemplary embodiment or embodiments, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof without departing from the scope of the invention. In addition, many modifications may be made to adapt a particular situation or material to the teachings of the invention without departing from the essential scope thereof. Therefore, it is intended that the invention not be limited to the particular embodiment disclosed as the best mode contemplated for carrying out this invention, but that the invention will include all embodiments falling within the scope of the claims. Also, in the drawings and the description, there have been disclosed exemplary embodiments of the invention and, although specific terms may have been employed, they are unless otherwise stated used in a generic and descriptive sense only and not for purposes of limitation, the scope of the invention therefore not being so limited. Moreover, the use of the terms first, second, etc. do not denote any order or importance, but rather the terms first, second, etc. are used to distinguish one element from another. Furthermore, the use of the terms a, an, etc. do not denote a limitation of quantity, but rather denote the presence of at least one of the referenced item.
