When the flow switch engages the upper end of the inner casing, the flow diversion valve opens and at least a portion of the fluid flow through the casing removal system exhausts to the annulus. The remaining fluid flow below the flow diversion valve is insufficient to operate a mud motor that drives a casing cutter. In other embodiments, when the flow switch is not engaged with the inner wall of casing, the flow diversion valve prevents fluid flow to components that are downhole of the valve and when the flow switch is engaged with the inner wall of casing, the flow diversion valve allows for fluid flow to components that are downhole of the valve.

Abstract: A frac plug with lower slips and a lower cone. In embodiments, a lower cone ramp angle is greater than or equal to a cone bevel angle and a slip inner cut angle. This geometry enables the fins of the cone to not interact with the lower slips, which may not break the lower slips as the lower slips move over the cone. Instead, the lower slips may break due to stresses caused by the tendency of the lower slips to expand as they lower slips interact with the ramp of the lower cone.

In addition, a second control signal may be generated to cause the two plates to impact with a second frequency or amplitude to steer the direction of drilling, such as when the wellbore has deviated from the target path of a well plan. The control signals may be associated with one or more geological formations.
