Abrasive Water Jet Perforation and Multi-Stage Fracturing gives petroleum engineers, well completion managers and fracturing specialists a critical guide to understanding all the details of the technology including materials, tools, design methods and field applications. The exploitation and development of unconventional oil and gas resources has continued to gain importance, and multi-stage fracturing with abrasive water jets has emerged as one of the top three principal methods to recover unconventional oil and gas, yet there is no one collective reference to explain the fundamentals, operations and influence this method can deliver. The book introduces current challenges and gives solutions for the problems encountered. Packed with references and real-world examples, the book equips engineers and specialists with a necessary reservoir stimulation tool to better understand today's fracturing technology.- Provides understanding of the fundamentals, design and application of water jet perforation- Examines the pressure boosting assembly in all phases including initiation, hydraulic isolation and production stage- Evaluates production analysis, pump pressure predictions and the latest design software- Introduces current challenges and gives solutions for the problems encountered

Chapter One

Theoretical Basis of Abrasive Jet

Abstract

Water jet with high pressure can successfully cut rock, steel, and even reinforced concrete. However, at lower pressure, mixing a certain amount of abrasive particles in the water jet can also greatly improve the jet ability and effectively cut materials. High-pressure water jet blended with abrasives is known as an abrasive jet.

This chapter provides a detailed overview of the literature related to abrasive jet, the theoretical basis, and the cutting mechanism utilized. The review in this chapter specifically addresses three types of abrasive jet. According to the nature of the fluid, abrasive jets can be divided into abrasive water and abrasive suspension jets. Furthermore, depending on the mixing method, abrasive water jets can be divided into post- and premixed abrasive water jets. Different types of abrasive jets have different jet characteristics, and their uses are not identical.
