摘要：
A perforating gun may include a gun carrier extending in an axial direction and a tandem seal adapter (TSA). The gun carrier having a maximum outer carrier diameter. The TSA may include a first TSA region having a first TSA outer diameter, a second TSA region having a second TSA outer diameter, and a shoulder surface formed between an outer surface of the first TSA region and an outer surface of the second TSA region. The second TSA outer diameter may be larger than the first TSA outer diameter and smaller than the maximum outer carrier diameter. A portion of the gun carrier may abut with the shoulder surface.
