The use of low viscosity fluids for hydraulic fracturing has a history as long as hydraulic fracturing itself. In the last fifty years, as more viscous fluids gained in popularity, the application of low viscosity fracturing fluids declined. In the last decade, however, the application of low viscosity fracturing fluids, such as, treated water in hydraulic fracturing has seen a resurgence in the industry. This presentation will focus on: Why this resurgence is occurring? Why use water as a fracturing fluid and why now?
In addition to answering these questions, the presentation will address the inherent risks of low viscosity fracturing fluids and identify guidelines for their successful application by outlining risk mitigating tests and treatment designs. These guidelines were developed through extensive theoretical and numerical research and tested via numerous field applications throughout the world.
Finally, this presentation will site additional uses and benefits of thin fluids for both completion and reservoir engineering purposes. Such additional uses can play a significant role in the optimization, design, and field execution of a fracturing treatment to ensure maximum productivity and that the economic value of the resource is being maximized.

Since joining NSI in early 1999, Larry has specialized in the development and application of solutions to hydraulic fracturing problems throughout the world and owns and operates Britt Rock Mechanics Laboratory at the University of Tulsa.
Britt’s experience includes the optimization, design, and execution of fracture stimulations and integrated field studies throughout the world. Prior to joining NSI he worked for Amoco Production Company for nearly twenty years. During the last six years with Amoco, he was fracturing team leader at Amoco’s Technology Center in Tulsa, Oklahoma, where he was charged with managing the development and application of fracturing technology for Amoco’s worldwide operations.
Larry has twice served as an SPE Distinguished Lecturer, as a JPT editor, and on numerous SPE Forum Committees on Gas Reservoir Engineering and Hydraulic Fracturing. In addition, Larry has authored over thirty technical papers for the SPE on reservoir management, pressure transient analysis, and hydraulic fracturing as well as co-authored the SPE Primer on the “Design and Appraisal of Hydraulic Fractures”.
