  • Perforating gun with rotatable charge tube
    Patent number: 8684083
    Abstract: A perforating gun designed to orient a charge holding structure (e.g., tube, solid rod) within a barrel of the perforating gun to be at the same position relative to a wellbore casing regardless of a position of the barrel of the perforating gun. A charge assembly receivable within the barrel includes the charge holding structure and first and second end caps that are rotatably interconnected to the charge holding structure and non-rotatably interconnected to the barrel. As the charge holding structure is always or substantially always designed to maintain a common orientation in relation to the wellbore casing, explosive charges associated with the charge holding structure so as to fire towards particular location on the wellbore casing may always or substantially always perforate such particular locations upon or after the explosive charges have fired.
