Hydraulic Fracturing in Unconventional Reservoirs

Chapter Five

Hydraulic Fracturing Fluid Systems

Abstract

This chapter starts with a detailed discussion on slick water and cross-linked gel fluid systems and their applications. Next, hybrid fluid systems and their applications in hydraulic fracturing of shale reservoirs are explained. An introduction on foam fracturing including detailed discussions on foam quality and foam stability is also presented. Finally, the concept of tortuosity is explored ending with typical slick water frac steps including acidizing, pad, proppant, and flush stages.
