EQUIPMENT FOR REMOTE LAUNCHING OF CEMENTING PLUGS |
摘要 |
An apparatus for remotely launching cementing plugs is configured such that the length of a dart is not necessarily the same as the corresponding plug to be launched. Such a design presents operational and ergonomic advantages, particularly in an offshore environment. Methods for launching cementing plugs and cementing a subterranean well are also presented.
