Abstract
An improved method and apparatus for catching and holding a ball, plug or dart during oil and gas well operations (e.g., cementing operations) employs a specially configured tool body that accepts a ball or a plug or a dart that flows downwardly into the tool body but disallows escape or discharge of the ball, plug or dart upwardly. The tool body has first and second flow channels or passages, one being generally axially aligned with the tool body. The other flow channel or passage is a second channel or passage that enables fluid flow around a cavity that contains one or more captive plugs (or ball or dart(s)).
