Abstract: A BHA features an MWD tool connected to a running tool supporting a whipstock that is connected to an open hole anchor. The anchor is flow set and after the anchor is set the running tool collets release from the whipstock to allow cement to be pumped through the anchor to hold the set position. The collets are released from the whipstock also with flow and after the anchor has been set. One way is to use nozzles in series. Another is to run in with a ball on the anchor seat, set the anchor and blow out the ball seat so flow can again be used to release the running tool collets. Another is suspending a ball above the anchor seat, releasing the ball with pressure cycle, open another flow passage to allow collet release of the whipstock. Finally, pressure can be used to release the running tool collets.

Abstract: Fracking ports are initially obstructed with respective biased sleeves that have an associated release device responsive to a unique signal. The signal can be electronic or magnetic and delivered in a ball or dart that is dropped or pumped past a sensor associated with each release device. Each sensor is responsive to a unique signal. When the signal is received the release device allows the bias to shift the sleeve to open the fracture port and to let a flapper get biased onto an associated seat. The flapper and seat are preferably made from a material that eventually disappears leaving an unobstructed flow path in the passage. The method calls for repeating the process in an uphole direction until the entire zone is fractured. The flapper and seat can dissolve or otherwise disappear with well fluids, thermal effects, or added fluids to the well.
