Abstract

A method and apparatus for perforating a wellbore by firing one or more projectiles into a casing and formation using a single source of energy.

First claim

What is claimed is:

1 . A perforating gun system comprising:
a cylindrical housing with an outer surface, a center axis, an internal pressure chamber, a cylindrical thru hole extending axially from the internal pressure chamber and terminating at a first end of the cylindrical housing; an energy source disposed within the pressure chamber; a plurality of cylindrical ports extending radially from the thru hole to the outer surface of the cylindrical housing; a plurality of projectiles, one each disposed in each of the plurality of cylindrical ports; a plurality of pressure seals, one each disposed in each of the plurality of cylindrical ports; and an end cap pressure seal capping off the end of the cylindrical thru hole where it terminates at the first end, wherein energy source generates a gas at a pressure sufficient to propel the plurality of projectiles through the pressure seals and into a casing surrounding the perforating gun system.

2 . The perforating gun system of claim 1 wherein each of the plurality of cylindrical ports extend tangentially to the center axis of the cylindrical housing.

3 . The perforating gun system of claim 1 wherein each of the plurality of cylindrical ports extend at a non-normal angle to the center axis of the cylindrical housing.

4 . The perforating gun system of claim 1 wherein each of the plurality of cylindrical ports extend non-linearly from the center axis of the cylindrical housing.

5 . The perforating gun system of claim 1 wherein the plurality of cylindrical ports has a phase angle between each cylindrical port about the center axis of the cylindrical housing.

6 . The perforating gun system of claim 1 wherein the plurality of cylindrical ports are in a single phase.

7 . The perforating gun system of claim 1 wherein the plurality of cylindrical ports are in a single plane.

8 . The perforating gun system of claim 1 wherein the plurality of cylindrical ports are in a plurality of planes.

9 . The perforating gun system of claim 1 wherein the cylindrical housing is a first cylindrical housing, containing the pressure chamber, coupled to a second cylindrical housing containing the plurality of cylindrical ports.

10 . The perforating gun system of claim 9 further comprising the first cylindrical housing has a pin end that engages into a box end of the second cylindrical housing.

11 . A perforating gun system comprising:
a first cylindrical housing with an outer surface, an internal pressure chamber, a cylindrical thru hole extending axially from the internal pressure chamber and terminating at a first end of the first cylindrical housing; a second cylindrical housing coupled in series with the first cylindrical housing, having an outer surface, a cylindrical thru hole, and a plurality of cylindrical ports extending radially from the thru hole to the outer surface of the second cylindrical housing, wherein both first cylindrical housing and second cylindrical housing share a common center axis; an energy source disposed within the pressure chamber; a plurality of projectiles, one each disposed in each of the plurality of cylindrical ports; a plurality of pressure seals, one each disposed in each of the plurality of cylindrical ports; and an end cap pressure seal capping off the end of the cylindrical thru hole where it terminates at an end of the second cylindrical housing, wherein energy source generates a gas at a pressure sufficient to propel the plurality of projectiles through the pressure seals and into a casing surrounding the perforating gun system.

12 . The perforating gun system of claim 11 wherein each of the plurality of cylindrical ports extend tangentially to the center axis of the second cylindrical housing.

13 . The perforating gun system of claim 11 wherein each of the plurality of cylindrical ports extend at a non-normal angle to the center axis of the second cylindrical housing.

14 . The perforating gun system of claim 11 wherein each of the plurality of cylindrical ports extend non-linearly from the center axis of the second cylindrical housing.

15 . The perforating gun system of claim 11 wherein the plurality of cylindrical ports has a phase angle between each cylindrical port about the center axis of the second cylindrical housing.

16 . The perforating gun system of claim 11 wherein the plurality of cylindrical ports are in a single phase.

17 . The perforating gun system of claim 11 wherein the plurality of cylindrical ports are in a single plane.

18 . The perforating gun system of claim 11 wherein the plurality of cylindrical ports are in a plurality of planes.

19 . The perforating gun system of claim 11 further comprising the first cylindrical housing has a pin end that engages into a box end of the second cylindrical housing.

20 . The perforating gun system of claim 11 further comprising the first cylindrical housing has an inner cavity that engages into a plug end of the second cylindrical housing.
