The patent describes a downhole perforating gun system featuring a cylindrical gun carrier that houses an inner body conductor, a charge holder, and a weight module with a bearing assembly for rotation based on gravity. This innovative design allows for wireless electrical communication and enhanced functionality in downhole perforation operations.

Claim 1

A downhole perforating gun system comprising: a first cylindrical gun carrier comprising a first end, a second end, and a central axis extending axially therethrough; an inner body conductor disposed within the first cylindrical gun carrier and being configured to communicate electrically in the downhole perforation gun system; a charge holder disposed within the first cylindrical gun carrier and being configured to hold at least one charge; a first bearing assembly disposed within the first cylindrical gun carrier such that the charge holder is rotatable relative to the first cylindrical gun carrier; and a weight module comprising one or more weights, wherein the weight module is rotatable by the weights via the first bearing assembly based on gravity acting on one or more of the one or more weights. a first cylindrical gun carrier comprising a first end, a second end, and a central axis extending axially therethrough; an inner body conductor disposed within the first cylindrical gun carrier and being configured to communicate electrically in the downhole perforation gun system; a charge holder disposed within the first cylindrical gun carrier and being configured to hold at least one charge; a first bearing assembly disposed within the first cylindrical gun carrier such that the charge holder is rotatable relative to the first cylindrical gun carrier; and a weight module comprising one or more weights, wherein the weight module is rotatable by the weights via the first bearing assembly based on gravity acting on one or more of the one or more weights.
