Turning of fracture from a deviated wellbore

Abstract

The turning of hydraulic fracture from a deviated wellbore is analyzed. And, the initiation and propagation of hydraulic fractures from a horizontal wellbore are discussed in this chapter.

Introduction

Consider a horizontal wellbore as sketched in Fig. 6-1. Since the vertical distribution of horizontal in situ stresses is no longer symmetric with respect to the wellbore axis, the propagation characteristics of a hydraulic fracture from a horizontal wellbore are very different from its vertical counterpart. In a ...
