Perforating gun
A perforating gun for use in oil and gas operations. The gun is carried to a desired area of a wellbore using only fluid pressure. The gun comprises a charge housing disposed within a removable sleeve. The charge housing comprises a plurality of shaped charges in communication with one or more sensors. The sensors are programmed to initiate the detonation sequence of the shaped charges upon measuring set parameters. Upon detonation, the gun fragments into a plurality of pieces that may be washed away from the detonation site.
1. A method of using a tool in an environment, the tool comprising:
an elongate body carrying a plurality of explosive charges, in which the elongate body is installed within a removable sleeve, and in which a helical groove is formed in an outer surface of the sleeve;
a collar counter in communication with the plurality of explosive charges, in which the collar counter is configured to initiate a detonation sequence of the plurality of explosive charges, and in which the collar counter is configured by external input on an interface, the interface configured to communicate wirelessly with the collar counter;
the environment comprising:
a wellbore formed within the ground and having a casing installed therein, in which the casing comprises a plurality of collars; and in which the wellbore comprises a horizontal section;
the method comprising:
configuring the collar counter to initiate the detonation sequence of the plurality of explosive charges once the collar counter counts a specified number of collars within the casing as the tool is lowered into the horizontal section of the wellbore; and
lowering the tool into the horizontal section of the wellbore using only fluid.
2. The method of claim 1 in which a wireline is not attached to the tool as it is lowered into the horizontal section of the wellbore.
3. The method of claim 1 , further comprising:
detonating the plurality of explosive charges; and
fragmenting the tool into a plurality of pieces.
4. The method of claim 1 , further comprising:
detonating the plurality of explosive charges;
thereafter, increasing fluid pressure within the casing; and
fragmenting the tool into a plurality of pieces.
5. The method claim 1 in which the sleeve is made of a foam material.
