摘要： The present invention provides an apparatus and method of orienting perforating gun strings conveyed on a tool string. One embodiment of the present invention provides an orienting weight provided in a portion of the perforating device, such as the shaped charge, the loading tube or the gun housing. An adapter is provided intermediate the tool string that facilitates conveyance of the gun string downhole. Additionally, the adapter enables the gun string to rotate independent of the tool string.

摘要： A tool string for use in a well includes a filter sub (or trapped pressure regulator sub) that is used with other components to reduce trapped pressure. The filter sub filters out debris that may occur from various types of downhole operations, such as perforating operations. By filtering out larger debris, only gases, liquids, and smaller particles are allowed to enter various components of the tool string. Without the presence of larger solid debris inside certain components of the tool string, the likelihood of plugs being formed is reduced so that gases and liquids can more readily pass out of the tool string as the tool string is retrieved to the surface of the well and the well hydrostatic pressure decreases.
