    摘要： The present invention relates to the delivery of a plurality of chemical components in well bore applications. More particularly, this invention relates to delivery capsules and methods of using such delivery capsules for facilitating the delivery of at least a plurality of chemical components to subterranean well bores. In one embodiment, a method of supplying chemical components to a subterranean formation comprises placing a delivery capsule having at least a first chamber comprising a first chemical component and at least a second chamber comprising a second chemical component into the subterranean formation, and allowing the first and second components to be released from the delivery capsule. In other embodiments, the present invention provides a delivery capsule for facilitating the delivery of a plurality of chemical components to a well bore penetrating a subterranean formation comprising a first chamber containing a first chemical component and at least a second chamber containing a second chemical component.
