Downhole tool actuation apparatus and method

1. A ball seat of a ball drop apparatus to actuate a downhole component, comprising:

a plurality of ball seat bores extending therethrough; and

at least one passage extending therethrough, wherein at least one of the ball seat bores is adapted to seat and retain at least one ball introduced into a wellbore tubular after the ball seat is deployed in the wellbore tubular, the plurality of ball seat bores shaped to impart annular momentum to fluid passing therethrough, the ball seat bores shaped such that they are tangentially angled.

2. The ball seat of claim 1 wherein at least one of the ball seat bores is tapered to seat at least one ball therein.

3. The ball seat of claim 1 , wherein the ball seat bores are further shaped such that they have a radial angle.

4. The ball seat of claim 1 wherein the tangential angle ranges from about 1-45 degrees.

5. The ball seat of claim 3 wherein the radial angle ranges from about 1-45 degrees.

6. The ball seat of claim 1 , wherein the at least one passage is adapted for receipt of a communication line.

7. The ball seat of claim 1 , wherein the at least one passage is adapted for receipt of wireline or slickline.

8. A method of actuating a downhole component with a ball drop apparatus comprising:

conveying the ball drop apparatus in a wellbore tubular, the ball drop apparatus comprising a body with at least one ball seat bore extending therethrough and at least one passageway extending therethrough;

introducing at least one ball into the ball drop apparatus after the conveying;

providing a fluid to the body to seat the at least one ball into the ball drop apparatus, wherein the at least one ball seat bore is angled with respect to the body such that annular motion is imparted to the fluid and wherein the at least one ball seat bore is tangentially angled; and

seating and retaining the at least one ball into the at least one ball seat bore to actuate the downhole component.

9. The method of claim 8 wherein the at least one ball seat bore is tapered.

10. The method of claim 8 , further comprising providing a fluid to the body at a pressure sufficient to actuate the downhole component when the at least one ball is seated in the at least one ball seat bore.

11. The method of claim 8 , wherein the at least one ball seat bore further has a radial angle.

12. The method of claim 8 , wherein the ball drop apparatus is conveyed on coiled tubing.

13. The method of claim 8 , further comprising conveying a communication line therethrough the at least one passageway.

14. The method of claim 8 , further comprising conveying a wireline through the at least one passageway.

15. The method of claim 8 , further comprising conveying a wireline tool through the at least one passageway.
