Abstract
An improved apparatus and a method to insert a wireline through a blow out preventer to log an underbalanced open hole well without killing the well or causing formation damage while maintaining well control during the process. A dual throated blow out preventer () provides a moveable sealing element () to allow a wireline () and a drill string () to be placed in a well for assembly, then seals off the dual throat to isolate the drill string from the wireline, thereby permitting pressure to be maintained on both the wireline through a standard packoff arrangement () and on the drill string using the rams of the blow out preventer ().
