Impact of fluid viscosity on fracturing

The role of fluid viscosity in hydraulic fracturing is often underestimated. A higher viscosity can enhance the efficiency of proppant transport, especially in narrow fractures. Has anyone experimented with varying viscosities in their fracking projects? I’m curious about the impact on fracture mapping outcomes from your experiences.

And i’ve found that increasing viscosity can definitely help with proppant placement in tighter formations. It improves mapping reliability, but you have to balance it with pump efficiency to avoid delays. Has anyone found a sweet spot for viscosity that worked for their project?

But it’s interesting how viscosity can be like trying to pour syrup versus water; one flows easily while the other can get stuck if you’re not careful. I’ve played around with viscosities too, and noticed that too high can lead to pressure issues. Have you tried any specific viscosity ranges that worked best for your projects?
