<p>An improved method of breaking a fluid suspension gel is described, the method being characterized by a novel and improved breaker mechanism. Additionally, a method of fracturing featuring improved matter transfer or mobility, e.g., improved downwell proppant and/or other solids transport, along with or combined with the improved gel breaker means is disclosed. In yet another embodiment, the invention provides a method of fracturing, including the provision and use of a fracturing fluid suspension containing an effective amount of a solid particulate breaker material having delayed breaking or degradation characteristics, additionally including an amount of durable fibers and/or platelets sufficient to enhance wellbore solids, such as proppant, transport. In a preferred aspect, solid particulate matter, which comprises or is composed of a specified organic polymeric compound or composition having an average molecular weight of at least 10,000, or a mixture of such compounds or compositions, and which solid organic polymeric matter reacts or decomposes, as described, is combined in a fracturing fluid with or containing a specified gellant and proppant, to form a fracturing fluid suspension, and the suspension formed is pumped downwell and deposited as a gelled suspension in the subterranean formation, generally under fracturing conditions. Preferably, the solid particulate material is provided in the form of fibers.</p> |
