Method and design for high shot density perforating gun

Abstract

A perforating gun includes a plurality of shaped charges located at a first distance from a detonator along a plurality of detonating cords and forming a first group, wherein the first group of shaped charges is configured to be detonated simultaneously. The plurality of detonating cords are of the same length.

1 . A perforating gun comprising:
 a plurality of shaped charges located at a first distance from a detonator along a plurality of detonating cords and forming a first group,   wherein the plurality of shaped charges in the first group are configured to be detonated simultaneously.   
     
     
         2 . The perforating gun of  claim 1 , further comprising a plurality of shaped charges located at a second distance from the detonator along the plurality of detonating cords and forming a second group, wherein the plurality of shaped charges in the second group are configured to be detonated simultaneously. 
     
     
         3 . The perforating gun of  claim 1 , wherein the plurality of shaped charges are evenly spaced around a circumference of the perforating gun. 
     
     
         4 . The perforating gun of  claim 1 , wherein the plurality of shaped charges are unevenly spaced around a circumference of the perforating gun. 
     
     
         5 . The perforating gun of  claim 1 , wherein the plurality of detonating cords are of the same length. 
     
     
         6 . The perforating gun of  claim 1 , wherein the plurality of detonating cords are pre-marked with distance markers along their lengths. 
     
     
         7 . The perforating gun of  claim 1 , wherein the plurality of detonating cords comprises a splitter having a single input and multiple outputs. 
     
     
         8 . A method for manufacturing a perforating gun, the method comprising:
 positioning a plurality of shaped charges in a housing of the perforating gun, wherein the plurality of shaped charges are disposed at a first distance from a detonator; and   connecting a plurality of detonating cords to each of the plurality of shaped charges, wherein the plurality of detonating cords are configured to provide simultaneous detonation of the plurality of shaped charges.   
     
     
         9 . The method of  claim 8 , wherein the plurality of detonating cords are of the same length. 
     
     
         10 . The method of  claim 8 , wherein the plurality of detonating cords are pre-marked with distance markers along their lengths. 
     
     
         11 . A method for using a perforating gun, the method comprising:
 providing the perforating gun in a borehole, wherein the perforating gun comprises:
 a plurality of shaped charges located at a first distance from a detonator along a plurality of detonating cords and forming a first group, 
 wherein the first group of shaped charges is configured to be detonated simultaneously; and 
   detonating the perforating gun to fire the plurality of shaped charges simultaneously.   
     
     
         12 . The method of  claim 11 , wherein the plurality of detonating cords are of the same length. 
     
     
         13 . The method of  claim 8 , wherein the plurality of detonating cords are pre-marked with distance markers along their lengths.
