Abstract
A pressure pulse generator and an RSS may change the pressure of a fluid flow through a BHA. If the dogleg at the BHA is less than a target dogleg, then the pressure pulse generator goes into pass-through mode to increase the pressure at the RSS and thereby increase a pad force of the RSS steering pads, increasing the severity of the dogleg. If a downhole tool is stuck, then the pressure pulse generator and the RSS are simultaneously actuated to unstick the downhole tool. The RSS is used to generate and transmit pressure pulses to a downhole tool.
