In one embodiment, the methods comprise: providing a linear gelled fluid that comprises an aqueous base fluid, a plurality of particulates, and a linear particulate transport enhancing additive, the linear gelled fluid having a certain yield stress, crossover frequency, and/or particulate settling time; introducing the linear gelled fluid into the subterranean formation; and using the linear gelled fluid to create or enhance at least one fracture in at least a portion of the subterranean formation. | 08-06-2009 |
20100181070 | Methods of designing treatment fluids based on solid-fluid interactions - Methods that comprise selecting proppant for use in a fracturing fluid based on one or more factors, wherein the one or more factors comprise an interaction between the proppant and the fracturing fluid. Methods that comprise designing a treatment fluid that comprises a gelled base fluid and a particulate based on one or more factors, wherein the one or more factors comprise an interaction between the particulate and the gelled base fluid. | 07-22-2010 |
20110061451 | Apparatus and Method for Measuring Rheological Properties of a Fluid Containing Particulate - An apparatus and a method for testing a viscosified fluid containing particulate indicate when the particulate is in suspension within the fluid and when it is not. The apparatus and method stir the fluid and particulate mixture for a time during which the viscosity of the fluid changes such that during a first period of the stirring time substantially all the particulate remains suspended in the fluid and during a second period of the stirring time substantially all the particulate settles out of suspension in the fluid. A signal is generated during the first and second periods such that the signal has a characteristic that changes from the first period to the second period to indicate the change in particle carrying ability of the fluid. Other characteristics, including crosslinking time, can also be determined. A test chamber includes projections extending from the inner surface of a cup receiving the fluid and from an axial support extending into the fluid in the cup. | 03-17-2011 |
20110214859 | Clean Viscosified Treatment Fluids and Associated Methods - Treatment fluids comprising an aqueous base fluid, a compliant cellulosic viscosifying agent, a crosslinking agent, and a protective ligand are provided. The present invention provides methods of using the treatment fluids in subterranean formations. One example of a suitable method includes providing a fracturing fluid comprising an aqueous base fluid, a compliant cellulosic viscosifying agent, a crosslinking agent, and a protective ligand and introducing the fracturing fluid into at least a portion of a subterranean formation at a rate and pressure sufficient to create or enhance at least one or more fractures in the subterranean formation. | 09-08-2011 |
20110214860 | Clean Viscosified Treatment Fluids and Associated Methods - The present invention relates to low environmental impact treatment fluids comprising a compliant crosslinking agent, and methods of use employing such treatment fluids to treat subterranean formations. The methods include providing a low environmental impact treatment fluid including an aqueous base fluid, a viscosifying agent, and a compliant crosslinking agent that comprises an iron ion and a non-iron crosslinking metal ion; and placing the treatment fluid in a subterranean formation. In some embodiments, the viscosifying agent may be a compliant viscosifying agent. | 09-08-2011 |
