Novel and High Performing Wellbore Cleaning Fluids with Surprisingly Flat Viscosity over Time and Different Temperatures


Roderick Pernites, Felipe Padilla, Jordan Clark, Angel Gonzalez, Diankui Fu (BJ Services)

Description:  Cementing of the casing is critical in well completion and is highly dependent on wellbore cleaning of the drilling mud prior to cement placement. This paper presents a highly unique and cost-effective wellbore cleaning fluid, which provides superior wellbore cleaning and efficient mud displacement. 



Can Friction Reducers Transport Sand During Fracturing Treatment?

URTeC 2873723:

Lingjuan Shen, Leonid Vigderman, David Heller, Diankui Fu (BJ Services)

Description:  This paper provides a comprehensive study of friction reducers as linear or crosslinked guar system replacement for transporting proppant. An in-depth understanding of the key factors controlling proppant carrying capability of FRs is critical to improved fracturing fluid design.



Multifunctional Surfactant Provides Superior Post Frac Production by Enhancing Polymer and Load Fluid Recovery

URTeC 2902575:

Ronald Plasier, Javier Leguizamon, Kevin Cooney (BJ Services); John Delorey (Delorey Consulting Inc), Corey Thomson (Paramount Resources)

Description:  This paper illustrates how the use of a Multifunctional Surfactant (MFS) can improve initial production and sustain production in underpressurized, liquids-rich, tight sandstone (SS) reservoirs such as the Glauconite formation in West-Central Alberta.




Gelled Isolation Fluid Makes Refracturing Well Feasible

Richard Wheeler, V. Williams, J. Mayor (Baker Hughes), S. Khan,  N. Everson (BJ Services), Steinhardt (BP America)

Description:  A gelled fluid offers the benefits of being both temporary and easily cleaned up after the treatment. The objective in this application was to use a low cost gelled fluid to fully isolate existing perforations along a lateral to stimulate new zones. The novelty of this work included the application of using a gelled fluid in conjunction with a sliding sleeve system.
