Abstract

The FastFrac Composite Bridge Plug is a composite Bridge Plug targeting a low pressure and low temperature application. The unique feature in this Bridge Plug is that we construct the mandrel out of non-metallic material (composite or plastic) and the mandrel itself is parted when setting the plug. The setting force of any plug or packer must be controlled to ensure sufficient force is applied to the packing element and slips for the plug or packer to engage the casing to provide an adequate seal and slip engagement to prevent movement in the casing. The mandrel on our FastFrac Composite Plug incorporates this setting feature. It also incorporates the unique feature of creating a clutching feature with the remaining upward facing face of the mandrel. This clutching feature provides the ability to stack multiple plugs in a well bore, thus aiding in the removal of the plug. Removal techniques typically involve the use of milling or drilling the plug and flowing the debris to surface.

Historically other metallic products have incorporated these features, but accomplishing these goals with non-metallic mandrels has not been done prior to the introduction of the new FastFrac Composite Bridge Plug (to the best of our knowledge). The advantage of such an approach is the simplification of the packer or plug and thus reduction of cost of the product.

Although we are introducing this technology into the FastFrac Composite Bridge Plu...
