Frac plug system having an integrated setting tool
A downhole tool has a setting cone including a body having an outer surface having a first end, a second end. At least a portion of the body includes a taper at the second end. A passage extends through the body. The passage includes a first portion having a first diameter and a second portion having a second diameter that is less than the first diameter. An anchor is arranged at the second end of the setting cone. The anchor includes a central passage that aligns with the passage through the setting cone. A mandrel extends through the passage of the setting cone and the central passage of the anchor. The mandrel includes a first end portion, a second end portion and an intermediate section. A conduit extends from the first end portion toward the second end portion. A portion of the conduit defines an actuation chamber.

9. The downhole tool according to claim 8 , further comprising: a seal arranged on the frusto-conical surface.
10. The downhole tool according to claim 1 , wherein the actuation chamber defines a power charge chamber housing an amount of propellant.
11. The downhole tool according to claim 1 , further comprising: a power charge arranged in the passage and extending about a portion of the intermediate portion of the mandrel.
12. The downhole tool according to claim 11 , an actuator head arranged at the first end portion of the mandrel in the actuation chamber.
13. The downhole tool according to claim 12 , wherein the conduit extends between the actuator head and the power charge.
14. A resource exploration and recovery system comprising:
a first system; and
a second system operatively connected to the first system through a wireline, the wireline supporting a downhole tool comprising:
