BALL SEAT SUB
First Claim
1. A downhole tool for providing a pressure differential between sub-assemblies comprising:
- an elongated body;
a tubular assembly disposed within the elongated body, the tubular assembly comprising;
a central flowbore with an inner diameter, anda central longitudinal axis;
a camming device;
an actuator member located below the tubular assembly, having a dual-bore configuration, the actuator member comprising;
a first bore;
a second bore; and
a concave seating surface formed within the first bore for receiving an obstructing device,wherein the first bore and the second bore are oriented 90 degrees to one another so that fluid may flow through the actuator while it is in either a first or a second position; and
a stationary sleeve concentrically disposed between the actuator member and the elongated body.

14. A method of operating a downhole tool for providing a pressure differential between sub-assemblies, the method comprising:
-
running a setting tool downhole tool to a desired location in a wellbore, the downhole tool comprising; an elongated body; a tubular assembly disposed within the elongated body, the tubular assembly further comprising; a central flowbore with an inner diameter, and a central longitudinal axis; a camming device; an actuator member having a dual-bore configuration, the actuator member further comprising; a first bore; a second bore; a concave seating surface formed within the first bore for receiving an obstructing device; and a stationary sleeve disposed between the actuator member and the elongated body, wherein the actuator member is aligned axially in a first position and located below the tubular assembly; circulating a fluid through the central flowbore; disposing the obstructing device into the fluid, wherein the fluid guides the obstructing device into the seating surface; and providing a pressure differential between an upper sub and a lower sub to activate the downhole tool. - View Dependent Claims (15, 16, 17, 18, 19, 20)
