Abstract
A single trip multizone time progressive well treating method and apparatus that provides a means to progressively stimulate individual zones through a cased or open hole well bore. This system allows the operator to use pre-set timing devices to progressively treat each zone up the hole. At each zone the system automatically opens a sliding sleeve and closes a frangible flapper, at a pre-selected point in time. An adjustable preset timing device is installed in each zone to allow preplanned continual frac operations for all zones. The apparatus is present as a 'Frac Module' that can consist of three major components, a packer, a timing pressure device, and a sliding sleeve/isolation device. A hydraulic packer may be removed or replaced with a swellable type packer.
