     FIELD OF INVENTION 
     The present invention relates generally to downhole tools and methods thereof and, more particularly, to an improved grapple release tool and methods thereof. 
     BACKGROUND OF THE INVENTION 
     A downhole tool may be used to quickly disconnect from a bottom hole assembly (BHA) if the bottom hole assembly becomes stuck in a well bore. 
     However, the downhole tool may be accidentally activated if something other than an intended dart lands (e.g., drifts, darts for other tools, etc.) on its activation seat. 
     Thus, an improved grapple release tool is needed to eliminate this problem. 
     SUMMARY OF THE INVENTION

     DETAILED DESCRIPTION OF EMBODIMENTS OF THE INVENTION 
     The following detailed description of various embodiments of the present invention references the accompanying drawings, which illustrate specific embodiments in which the invention can be practiced. While the illustrative embodiments of the invention have been described with particularity, it will be understood that various other modifications will be apparent to and can be readily made by those skilled in the art without departing from the spirit and scope of the invention. Accordingly, it is not intended that the scope of the claims appended hereto be limited to the examples and descriptions set forth herein but rather that the claims be construed as encompassing all the features of patentable novelty which reside in the present invention, including all features which would be treated as equivalents thereof by those skilled in the art to which the invention pertains. Therefore, the scope of the present invention is defined only by the appended claims, along with the full scope of equivalents to which such claims are entitled. 
     Grapple Release Tool 
     Tool Assembly 
     The grapple release tool may be used to quickly disconnect from a bottom hole assembly (BHA) if the bottom hole assembly becomes stuck in a well bore. 
     The grapple release tool may be placed in strategic places within the bottom hole assembly (BHA) to provide optimal results when retrieving the bottom hole assembly from a stuck position in the well bore. 
     Once the bottom hole assembly becomes stuck, an operator makes a decision to activate the grapple release tool. In the activated position, the grapple release tool opens a fluid bypass to maintain circulation. Once the grapple release tool is activated, the grapple release tool opens a fluid path to allow well control operations, if needed, and to allow a ball to be deployed to shift the upper ball seat if a larger fluid path is needed. 
     To activate the grapple release tool, an upper dart may be placed inside the drill string and deployed by gravity or by pumping down the bore of the drill string. Once the upper dart lands on inside the upper box recut insert, the grapple release tool diverts fluid flow (pressure) to a piston bias area of the upper piston. The grapple release tool (e.g., shift-up upper piston design) prevents an accidental activation if something other than an intended dart lands (e.g., drifts, darts for other tools, etc.) on the upper box recut insert. 
     Once sufficient fluid flow (pressure) has built up to overcome friction of a pop lock and a nose shear screw, the grapple release tool shifts the upper piston upward, releasing a finger on the pop lock from a main body. The grapple release tool separates cleanly, leaving a large path for fishing operations.

     Ball 
     In an embodiment, the grapple release tool  100  may further include a ball  2100 . 
     The ball may be made of any suitable material. For example, a suitable material includes, but is not limited to, a plastic, a rubber, and combinations thereof. In an embodiment, the ball  2100  may be made from a plastic. In an embodiment, the ball  2100  may be made from a rubber. 
     The ball  2100  may have an outer diameter  2105 . 
     The ball  210   o  may have any suitable outer diameter  2105 . For example, a suitable outer diameter  2105  may be from about 1.437-inches to about 5.437-inches, and any range or value there between. In an embodiment, the outer diameter  2105  may be about 3.437-inches. 
     Operation of Grapple Release Tool 
     The grapple release tool  100  may be placed in strategic places within the bottom hole assembly (BHA) to provide optimal results when retrieving the bottom hole assembly from a stuck position in the well. 
     Once the bottom hole assembly becomes stuck, an operator makes a decision to activate the grapple release tool  100 . In the activated position, the grapple release tool  100  opens a fluid bypass to maintain circulation. 
     To activate the grapple release tool  100 , an upper dart  240  may be placed inside the drill string and deployed by gravity or by pumping down the bore of the drill string. Once the upper dart  240  lands on inside the upper box recut insert  270 , the grapple release tool  100  diverts fluid flow (pressure) to a piston bias area of the upper piston  190 . The grapple release tool  100  (e.g., shift-up upper piston design) prevents an accidental activation if something other than an intended dart lands (e.g., drifts, darts for other tools, etc.) on the upper box recut insert  270 . 
     Once sufficient fluid flow (pressure) has built up to overcome friction of a pop lock  170  and a first nose shear screw  210 , the grapple release tool  100  shifts the upper piston  190  upward, releasing a finger  180   c  on the pop lock  170  from a main body  130 . The grapple release tool  100  separates cleanly at the main body  130  and the secondary housing  150 , leaving a large path for fishing operations. 
     Once the grapple release tool  100  is activated, the grapple release tool  100  connects one or more vents  248   a,    248   b,    248   c  in an upper dart  240 , one or more vents  199   a,    199   b,    199   c  in an upper piston  190  and a plurality of screw holes  140  in a main housing  130 , allowing fluid flow from an interior of the main body  130  to an exterior of the main body  130 . 
     If needed, a ball  260  to be deployed to shift the upper ball seat  290  downward if a larger fluid path is needed, as discussed below. 
     The ball  299  has an outer diameter  2100 . 
     In an embodiment, the ball  299  may have any suitable outer diameter  2100 . For example, a suitable outer diameter  2100  may be from about 1.437-inches to about 5.437-inches, and any range or value there between. In an embodiment, the outer diameter may be about 3.437-inches. 
     To shift the upper ball seat  290 , a ball  299  may be placed inside the drill string and deployed by gravity or by pumping down the bore of the drill string. Once the ball  299  lands on the upper ball seat  290 , the ball  299  seals the upper ball seat  290 . 
     Once sufficient fluid flow (pressure) has built up to overcome friction of the upper ball seat  290  and a second nose shear screw (not shown), the grapple release tool  100  shifts the upper ball seat  290  downward, exposing one or more vents  2001  in the top subassembly  110  and allowing fluid flow from an interior of the top subassembly  110  to an exterior of the top subassembly  110 .
