摘要：

An overshot has an articulated seal that can be set against the fish when the fish is engaged by the tool. The seal can be actuated from swelling due to exposure to well fluid or mechanically or hydraulically from the string that supports it. The use of spears or overshots with the articulated seal feature is contemplated. If a swelling design is used it can respond to water or hydrocarbons that are found at the subterranean location.
