Abstract
A wellhead ball launch detection system includes a detectable ball, and a detector, attachable to a wellhead, having an aperture, configured to detect passage of the detectable ball therethrough.
Claims20
A wellhead ball launch detection system, comprising:
- a detectable ball;
- and
- a detector, attachable to a wellhead, having an aperture, configured to detect passage of the detectable ball therethrough.
A wellhead ball launch system, comprising:
- a generally upright, first pressurizable tool, attachable to a wellhead, having an openable top, and an internal chamber;
- a plurality of selectively releasable ball holders, arranged in a substantially vertical array within the internal chamber, configured to retain a first plurality of detectable balls of varying diameter, in ascending order of ball diameter;
- and
- a detector, having an aperture, disposed below all of the selectively releasable ball holders, configured to detect passage of a detectable ball therethrough.
1 more element
A method for launching balls into a wellhead, comprising:
