Abstract
A method and apparatus for using a tandem sub to connect one or more perforating gun assemblies, having a rotational bearing mechanism lining the inner diameter in both ends to allow the charge tube assembly to rotate within the gun body.
Claims30
A tandem sub, used to connect one or more perforating gun assemblies, comprising:
- a first rotational mechanism located at a first end, wherein the first rotational mechanism is adapted to engage with a first charge tube in a first perforating gun and allow the first charge tube to rotate freely;
- a second rotational mechanism located at a second end, wherein the second rotational mechanism is adapted to engage with a second charge tube in a second perforating gun and allow the second charge tube to rotate freely;
- and
- an outer tandem housing, wherein the outer housing is adapted to engage a first outer gun housing of the first perforating gun and engage a second outer gun housing of the second perforating gun.
