Chapter 3

Proppant transport in a 3D fracture

Abstract

This chapter analyzes the transport of proppant in a 3D hydraulic fracture. The effect of proppant distribution on the propagation, shut-in, and closure of a hydraulic fracture is discussed. A brief discussion of pseudo 3D models is presented at the end of the chapter.

Introduction

In hydraulic fracturing operations, the fracture is first initiated with a solid-free fluid and then followed with fluids (or gel) with proppant. The solid-free fluid, or the so-called pad fluid, is used in the initial phase of fracturing to create a hydraulic fracture of desired dimensions ...
