Title: Boosterless ballistic transfer

Description:
BACKGROUND 
     After drilling various sections of a subterranean wellbore that traverses a formation, a casing string may be positioned and cemented within the wellbore. This casing string may increase the integrity of the wellbore and may provide a path for producing fluids from the producing intervals to the surface. To produce fluids into the casing string, perforations may be made through the casing string, the cement, and a short distance into the formation. 
     These perforations may be created by detonating a series of shaped charges that may be disposed within the casing string and may be positioned adjacent to the formation. Specifically, one or more perforating guns may be loaded with shaped charges that may be connected with a detonator via a detonation transfer line. The perforating guns may then be attached to a tool string that may be lowered into the cased wellbore. Once the perforating guns are properly positioned in the wellbore such that the shaped charges are adjacent to the formation to be perforated, the shaped charges may be detonated, thereby creating the desired perforations. 
     When an array of perforating guns is utilized, there is a gap between them that the detonation transfer line runs along. Previous devices and methods may leave the detonation transfer line partially exposed to the wellbore environment. This may lead to disconnection between the devices, misfires, or early detonations. These devices and methods include creating seals using the detonation transfer line itself, which is unreliable as the detonation transfer line may shrink under pressure. Further, boosters may be used at the ends of the detonation transfer line to aid in the transfer of detonation between a pair of perforating guns.

     DETAILED DESCRIPTION 
     This disclosure may generally relate to subterranean operations. More particularly, systems and methods may be provided for transferring detonation between a pair of ballistic apparatuses. Perforating systems and methods that use a ballistic transfer system may maximize cost savings by eliminating the need for boosters and enhance safety in all aspects of perforating activities by preventing misfires, early detonations, and contamination from the surrounding wellbore environment. 
       FIG.  1    illustrates an example of a downhole perforating system  100  operating from a platform  105 . Platform  105  may be centered over a subterranean formation  110  located below the surface  115 . A conduit  120  may extend from deck  125  of platform  105  to wellhead installation  130  including blow-out preventers  135 . Platform  105  may have a hoisting apparatus  140  and a derrick  145  for raising and lowering pipe strings, such as, for example, work string  150  which may include the downhole perforating system  100 . As illustrated, the downhole perforating system  100  may be disposed on a distal end of work string  150 . It should be noted that while  FIG.  1    generally depicts a subsea operation, those skilled in the art will readily recognize that the principles described herein are equally applicable to land-based systems, without departing from the scope of the disclosure. 
     Wellbore  155  may extend through the various earth strata including subterranean formation  110 . While downhole perforating system  100  is disposed in a horizontal section of wellbore  155 , wellbore  155  may include horizontal, vertical, slanted, curved, and other types of wellbore geometries and orientations in which downhole perforating system  100  may be disposed, as will be appreciated by those of ordinary skill in the art. A casing  160  may be cemented within wellbore  155  by cement  165 . When it is desired to perforate subterranean formation  110 , the downhole perforating system  100  may be lowered through casing  160  until the downhole perforating system  100  is properly positioned relative to subterranean formation  110 . The downhole perforating system  100  may be attached to and lowered via work string  150 , which may include a tubing string, wireline, slick line, coil tubing or other conveyance. Upon detonation, components within downhole perforating system  100  may form jets that may create a spaced series of perforations extending outwardly through casing  160 , cement  165 , and into subterranean formation  110 , thereby allowing formation communication between subterranean formation  110  and wellbore  155 . 
     Downhole perforating system  100  may include one or more ballistic apparatuses  170   a ,  170   b ,  170   c ,  170   d . The ballistic apparatus will be referred to herein collectively as ballistic apparatus  170   a ,  170   b ,  170   c ,  170   d  and individually as first ballistic apparatus  170   a , second ballistic apparatus  170   b , third ballistic apparatus  170   c , and fourth ballistic apparatus  170   d . Ballistic apparatuses  170   a ,  170   b ,  170   c ,  170   d  may be any device used in a perforating gun for perforating subterranean formation  110 , as explained in further detail below. Without limitation, ballistic apparatuses  170   a ,  170   b ,  170   c ,  170   d  may individually be a firing head (e.g., firing head  200  on  FIG.  2   ), a handling subassembly (e.g., handling subassembly  205  on  FIG.  2   ), a gun subassembly (e.g. gun subassembly  210  on  FIG.  2   ) and/or combinations thereof. Additional examples of ballistic apparatuses  170   a ,  170   b ,  170   c ,  170   d  may include, but are not limited to, tubing cutters and setting tools. Downhole perforating system  100  may also include a ballistic transfer system  175 , wherein the ballistic transfer system  175  may connect two or more ballistic apparatuses  170   a ,  170   b ,  170   c ,  170   d . In prior embodiments of downhole perforating system  100 , a detonation transfer line  180  (explained in further detail on  FIG.  2   ) would extend between and connect the ballistic apparatuses  170   a ,  170   b ,  170   c ,  170   d  to one another. There may be a need to protect at least a portion of detonation transfer line  180  that is exposed between the ballistic apparatuses  170   a ,  170   b ,  170   c ,  170   d  from the surrounding environment of wellbore  155 . Implementation of ballistic transfer system  175  may protect the at least a portion of detonation transfer line  180  from wellbore  155  and may create a pressure and liquid seal between ballistic apparatuses  170   a ,  170   b ,  170   c ,  170   d . There may be a plurality of ballistic transfer systems  175  disposed between ballistic apparatuses  170   a ,  170   b ,  170   c ,  170   d . As illustrated, each of the ballistic transfer systems  175  may individually form a sealed connection between first ballistic apparatus  170   a  and second ballistic apparatus  170   b , between second ballistic apparatus  170   b  and third ballistic apparatus  170   c , and between third ballistic apparatus  170   c  and fourth ballistic apparatus  170   d.    
       FIG.  2    illustrates an example of ballistic apparatus  170 . As illustrated, firing head  200  may be disposed at an upper end of downhole perforating system  100 . Handling subassembly  205  may be disposed between gun subassembly  210  and firing head  200 . Handling subassembly  205  may be coupled to firing head  200  and gun subassembly  210  by any suitable means, such as, for example, mechanical fasteners, welds and/or threads. Firing head  200  may include initiation device  215 . As illustrated, initiation device  215  may be disposed within at least a portion of firing head  200 . Firing head  200  may include detonating cord initiator  220 , detonation transfer line  180 , and donor booster  225  (bi-directional booster). Detonation transfer line  180  may extend from detonating cord initiator  220  to gun subassembly  210 . 
     Detonation transfer line  180  may be any suitable line for transferring detonation through a plurality of ballistic apparatuses  170 . Suitable detonation transfer lines may include, but are not limited to, detonation cords, shock tubes, and detonating fuses among others. Detonation transfer line  180  may include compressed particles of an explosive component. Without limitation, the explosive component in detonation transfer line  180  may include any suitable explosive material (i.e., nitramide) such as, octogen (HMX), hexanitrostilbene (HNS), 2,6-bis(picrylamino)-3,5-dinitropyridine (PYX), 4,10-Dinitro-2,6,8,12-tetraoxa-4,10-diazatetracyclo[5.5.0.05,9.03,11]-dodecane (TEX), triaminotrinitrobenzene or 2,4,6-triamino-1,3,5-trinitrobenzene (TATB), nonanitroterphenyl (NONA), hexogen (RDX), pentaerythritol tetranitrate (PETN), 1,3,5-trinitro-2,4,6-tripicrylbenzene (BRX), 1,3-diamino,2,4,6-trinitrobenzene (DATB), hexanitrobenzene (HNAB), nitrotriazolone (NTO) and/or combinations thereof. Detonation transfer line  180  may comprise an elongated body between two ends. Typically, a first end and/or a second end of detonation transfer line  180  may include any suitable booster, for example, compressed particles of an explosive component. 
     As illustrated, handling subassembly  205  may include an acceptor booster  230  (bi-directional booster) coupled to detonation transfer line  180 . Detonation transfer line  180  may be discontinuous between donor booster  225  and acceptor booster  230 . There may be air gap  235  between donor booster  225  and acceptor booster  230 . Donor booster  225  and acceptor booster  230  may include compressed particles of an explosive component. Without limitation, the explosive component may include any suitable explosive material. The donor booster  225  may be capable of transmitting a detonation across a discontinuity such as an air gap  235 . It does so by its own detonation, in response to a detonation of an adjacent secondary high explosive mass (e.g., detonation transfer line  180 ), the donor booster  225  detonation yielding a sufficiently high output to enable transmission across the air gap  235  or the like. Because of the output requirements, a donor booster  225  may include a secondary high explosive; such secondary boosters may not continue/allow a detonation over any discontinuity, for example, an air gap  235 . This may provide that donor booster  225  and detonation transfer line  180 , to which it is coupled, may be in direct physical contact. 
     An acceptor booster  230 , on the other hand, may be one which may detonates in response to another detonation, i.e., in response to the detonation of a donor booster  225  which may be spaced from the acceptor booster  230  by a discontinuity such as an air gap  235 . The acceptor booster  230  may further be capable of detonating another secondary high explosive mass (e.g., detonation transfer line  180 ) in operative association with it by means of the acceptor booster&#39;s  230  own detonation. Thus, an acceptor booster  230  may continue/allow a detonation from a donor booster  225 , even across a discontinuity, and may transmit the detonation to another secondary high explosive mass so as to continue/allow the detonation. Therefore, to continue/allow the detonation, an acceptor booster  230  may detonate, and not deflagrate. 
     Initiation device  215  may be coupled to detonating cord initiator  220  and may provide a substantial amount of the energy to initiate detonating cord initiator  220 . A signal (e.g., electrical, mechanical, etc.) may be sent form the surface  115  (e.g., shown on  FIG.  1   ) to activate initiation device  215 , which may in turn initiate detonating cord initiator  220 . Initiation device  215 , may include, but is not limited to, a rig environment detonator igniter, industry standard resistor detonators, hotwire igniters, exploding bridgewire igniters, exploding foil initiator igniters, conductive mix igniters, percussion actuated igniters, and a high tension igniting system. Detonating cord initiator  220  may include compressed particles of an explosive component. Without limitation, the explosive component in detonating cord initiator  220  may include any suitable explosive material. 
     With continued reference to  FIG.  2   , gun subassembly  210  may be coupled to detonation transfer line  180 . Gun subassembly  210  may include shaped charges  240 . Initiation of detonation transfer line  180  by initiation device  215  may set off a shock wave that initiates shaped charges  240 . 
     Gun subassembly  210  may further include a charge holder  245 . As illustrated, charge holder  245  may be in the form of a cylindrical sleeve. Charge holder  245  may include a plurality of charge holding recesses  250  which hold shaped charges  240 . The plurality of shaped charges  240  may be arranged in a spiral pattern such that each of the shaped charges  240  may be disposed on its own level or height and may be individually detonated so that only one shaped charge  240  may be fired at a time. Alternate arrangements of the plurality of shaped charges  240  may be used, including cluster type designs wherein more than one shaped charge  240  may be at a same level and may be detonated at the same time. Upon initiation, shaped charges  240  may generate a jet that may penetrate casing  160 , cement  165  and into subterranean formation  110 , which are shown on  FIG.  1   , for example. In order to ensure a successful detonation, ballistic transfer system  175  may be implemented in downhole perforating system  100 , as described herein with respect to  FIGS.  3 - 8   . 
       FIG.  3    illustrates an example of ballistic transfer system  175 . Ballistic transfer system  175  may serve to provide a transfer of detonation between a pair of adjacent ballistic apparatuses  170  (i.e., referring to  FIG.  1   ). Ballistic transfer system  175  may comprise a housing  300  and an alignment insert  305 . Housing  300  may be any suitable size, height, and/or shape. Without limitation, a suitable shape may include, but is not limited to, cross-sectional shapes that are circular, elliptical, triangular, rectangular, square, hexagonal, and/or combinations thereof. In examples, housing  300  may have a hollow, circular cross-section. Without limitation, housing  300  may comprise any suitable material such as metals, nonmetals, polymers, ceramics, and/or any combination thereof. 
     As illustrated, housing  300  may be disposed between first ballistic apparatus  170   a  and second ballistic apparatus  170   b . Housing  300  may comprise a first end  310 , a second end  315 , and a central axis  320 . First end  310  and second end  315  may be used interchangeably. In examples, first end  310  may be secured to first ballistic apparatus  170   a  and second end  315  may be secured to second ballistic apparatus  170   b , or vice versa. First end  310  and second end  315  may be secured through the use of any suitable mechanisms, including, but not limited to, the use of suitable fasteners, threading, adhesives, welding, and/or combinations thereof. Without limitation, suitable fasteners may include nuts and bolts, washers, screws, pins, sockets, rods and studs, hinges and/or any combination thereof. In examples, O-rings  325  may be used to seal a surface of housing  300  to first ballistic apparatus  170   a  and/or second ballistic apparatus  170   b . Housing  300  may be partially inserted into first ballistic apparatus  170   a  and/or second ballistic apparatus  170   b . Alternatively, first ballistic apparatus  170   a  and/or second ballistic apparatus  170   b  may be partially inserted into housing  300 . Prior to securing housing  300  between first ballistic apparatus  170   a  and second ballistic apparatus  170   b , alignment insert  305  may be disposed into housing  300 . 
     Alignment insert  305  may be disposed into housing  300  at first end  310  and/or second end  315 . Alignment insert  305  may be secured into housing  300  through the use of any suitable mechanisms, including, but not limited to, the use of suitable fasteners, threading, adhesives, welding, and/or combinations thereof. In alternate examples, alignment insert  305  may be secured about first ballistic apparatus  170   a  and/or second ballistic apparatus  170   b . Alignment insert  305  may be any suitable size, height, and/or shape. Without limitation, a suitable shape may include, but is not limited to, cross-sectional shapes that are circular, elliptical, triangular, rectangular, square, hexagonal, and/or combinations thereof. In examples, housing  300  may have a hollow, circular cross-section. Without limitation, alignment insert  305  may comprise any suitable material such as metals, nonmetals, polymers, ceramics, and/or any combination thereof. In examples, alignment insert  305  may comprise aluminum, steel, glass-filled Nylon, and/or combinations thereof. Alignment insert  305  may serve to align a first detonation transfer line  180   a  in relation to a second detonation transfer line  180   b . In examples, an end  330  of first detonation transfer line  180   a  and an end  335  of second detonation transfer line  180   b  may be inserted into alignment insert  305  in any suitable fashion so as to promote detonation transfer between the two. During operations, as first detonation transfer line  180   a  is aligned with second detonation transfer line  180   b , a transfer of detonation between first ballistic apparatus  170   a  and second ballistic apparatus  170   b  may occur without the use of boosters. 
     First detonation transfer line  180   a  and second detonation transfer line  180   b  may be used interchangeably. In examples, first detonation transfer line  180   a  may be a donating detonating cord from first ballistic apparatus  170   a , and second detonation transfer line  180   b  may be an accepting detonating cord from second ballistic apparatus  170   b . In alternate examples, second detonation transfer line  180   b  may be the donating detonating cord from second ballistic apparatus  170   b , and first detonation transfer line  180   a  may be an accepting detonating cord from first ballistic apparatus  170   a . In examples, either first detonation transfer line  180   a  or second detonation transfer line  180   b  may be disposed along central axis  320  of housing  300 . As illustrated, second detonation transfer line  180   b  may be disposed along central axis  320 , and first detonation transfer line  180   a  may be disposed about second detonation transfer line  180   b  within alignment insert  305 . As illustrated in  FIG.  3   , first detonation transfer line  180   a  may generally be disposed parallel about second detonation transfer line  180   b . As a portion of both first detonation transfer line  180   a  and second detonation transfer line  180   b  may be disposed through alignment insert  305 , there may be a central bore (not illustrated) running the length of alignment insert  305 . In some examples, there may be an internal cavity (not illustrated) disposed within first end  310  or second end  315  of housing  300  to accommodate first detonation transfer line  180   a  or second detonation transfer line  180   b , respectively. In some examples, first detonation transfer line  180   a  may be inserted into alignment insert  305  through a first end  340  of alignment insert, and second detonation transfer line  180   b  may be inserted into alignment insert  305  through a second end  345  of alignment insert  305 . In other examples, first detonation transfer line  180   a  may be inserted into alignment insert  305  through second end  345 , and second detonation insert  180   b  may be inserted into alignment insert  305  through first end  340 . 
     There may be a designated length of overlap between first detonation transfer line  180   a  and second detonation transfer line  180   b . Within this length of overlap there may be a maximum cord separation distance between first detonation transfer line  180   a  and second detonation transfer line  180   b . This measurement may be dependent on explosive loading of first detonation transfer line  180   a  and second detonation transfer line  180   b . Without limitations, the maximum cord separation distance may be about 0.062 inches (1.6 mm). In examples, the explosive loading of first detonation transfer line  180   a  and/or second detonation transfer line  180   b  may be about 40 gr/ft (8.5 g/m), 80 gr/ft (17 g/m), or 120 gr/ft (25.5 g/m). Typically, boosters may be used to facilitate a transfer of detonation between first ballistic apparatus  170   a  and second ballistic apparatus  170   b . With regards to the length of overlap and the maximum cord separation distance, transfer of detonation may occur without the use of boosters. 
     There may be a multitude of different configurations concerning first detonation transfer line  180   a  and second detonation transfer line  180   b  within alignment insert  305 , as illustrated in  FIGS.  4 - 6   . These different configurations may vary the shock pressure output of first detonation transfer line  180   a  and/or second detonation transfer line  180   b .  FIG.  4    illustrates an example of alignment insert  305  with a parallel configuration, as used in  FIG.  3   .  FIG.  5    illustrates an example of alignment insert  305  with a spiral configuration.  FIG.  6    illustrates an example of a looped configuration for first detonation transfer line  180   a  and second detonation transfer line  180   b , wherein one of the two is looped back and forth parallel to central axis  320  (i.e., referring to  FIG.  3   ) while the other is disposed in a straight line parallel to central axis  320 . As illustrated, a second alignment insert  400  may be used in conjunction with alignment insert  305 , as best seen in  FIGS.  4 - 5   . Second alignment insert  400  may provide support for one of first detonation transfer line  180   a  or second detonation transfer line  180   b . Further, second alignment insert  400  may be disposed so as to abut alignment insert  305 . In examples, alignment insert  305  may be disposed into housing  300  (e.g., referring to  FIG.  3   ) and second alignment insert  400  may be disposed in gun assembly  210  (e.g., referring to  FIG.  2   ). In alternate examples, alignment insert  305  may be disposed in gun assembly  210  and second alignment insert  400  may be disposed into housing  300 . 
     In examples, the spiral configuration may be used when first detonation transfer line  180   a  and/or second detonation transfer line  180   b  comprise insensitive explosive materials. Without limitations, these insensitive materials may be HNS, TATB, PYX, NONA, TEX, BRX, DATB, HNAB, NTO and/or combinations thereof. Alternatively, this configuration may also be used if either first detonation transfer line  180   a  and/or second detonation transfer line  180   b  comprise a jacket (not illustrated). In those examples, the jacket may retain the explosives during handling and may act as a flyer plate in order to increase the pressure transferred from the donor to the acceptor during detonations transfer. During operations, when an explosive adjacent to a layer of a metallic and/or other solid material detonates (i.e., the jacket), the layer may be accelerated both by the initial detonation shock wave and by the pressure of the detonation gas products. Without limitation, the jacket may comprise any suitable material such as metals, nonmetals, polymers, ceramics, and/or any combination thereof. In examples, the spiral configuration may be used to increase the permissible separation distance between first detonation transfer line  180   a  and second detonation transfer line  180   b  as compared to the parallel configuration (as best seen on  FIG.  4   ). 
     There may be a plurality of other configurations not presently illustrated. In some examples, the donor shock pressure output may be increased by inserting additional pieces of detonating cord into alignment insert  305  along first detonating transfer line  180   a  and/or second detonation transfer line  180   b . This may increase the shock pressure input experienced by second detonation transfer line  180   b  and may subsequently increase the likelihood that second detonation transfer line  180   b  initiates. While second detonation transfer line  180   b  may be illustrated as being straight and parallel to central axis  320  (i.e., referring to  FIG.  3   ), in other examples, second detonation transfer line  180   b  may be in a spiral, looped back and forth, and/or combinations thereof. In an alternate example, first ballistic apparatus  170   a  (i.e., referring to  FIG.  1   ) may be coupled directly to second ballistic apparatus  170   b  (i.e., referring to  FIG.  1   ) without the use of housing  300  (i.e., referring to  FIG.  3   ). Without limitations in this example, a pin may be used to couple one end of first ballistic apparatus  170   a  to a box connection on an end of second ballistic apparatus  170   b  by disposing said pin into said box connection. 
     With reference now to  FIGS.  7 - 8   , another configuration may be any of the preceding configurations wherein the first detonation transfer line  180   a  and second detonation transfer line  180   b  may be exposed to each other.  FIG.  7    illustrates a cross-sectional view of alignment insert  305 .  FIG.  8    illustrates a cross-sectional view along section X-X of alignment insert  305  as shown in  FIG.  7   . In regards to  FIGS.  7 - 8   , a channel  700  may be cut between first detonation transfer line  180   a  and second detonation transfer line  180   b . In examples, channel  700  may be any suitable size, height, and/or shape.

     The preceding description provides various examples of the systems and methods of use disclosed herein which may contain different method steps and alternative combinations of components. It should be understood that, although individual examples may be discussed herein, the present disclosure covers all combinations of the disclosed examples, including, without limitation, the different component combinations, method step combinations, and properties of the system. It should be understood that the compositions and methods are described in terms of “comprising,” “containing,” or “including” various components or steps, the compositions and methods can also “consist essentially of” or “consist of” the various components and steps. Moreover, the indefinite articles “a” or “an,” as used in the claims, are defined herein to mean one or more than one of the element that it introduces. 
     For the sake of brevity, only certain ranges are explicitly disclosed herein. However, ranges from any lower limit may be combined with any upper limit to recite a range not explicitly recited, as well as, ranges from any lower limit may be combined with any other lower limit to recite a range not explicitly recited, in the same way, ranges from any upper limit may be combined with any other upper limit to recite a range not explicitly recited. Additionally, whenever a numerical range with a lower limit and an upper limit is disclosed, any number and any included range falling within the range are specifically disclosed. In particular, every range of values (of the form, “from about a to about b,” or, equivalently, “from approximately a to b,” or, equivalently, “from approximately a-b”) disclosed herein is to be understood to set forth every number and range encompassed within the broader range of values even if not explicitly recited. Thus, every point or individual value may serve as its own lower or upper limit combined with any other point or individual value or any other lower or upper limit, to recite a range not explicitly recited. 
     Therefore, the present examples are well adapted to attain the ends and advantages mentioned as well as those that are inherent therein. The particular examples disclosed above are illustrative only, and may be modified and practiced in different but equivalent manners apparent to those skilled in the art having the benefit of the teachings herein.
