Chapter 1 Introduction

The Engineered Solutions Guide for Clear Brine Fluids and Filtration has been developed by TETRA in an effort to assist our customers in planning for and engineering well completions designed to maximize well performance and profitability. We hope that this publication provides useful information and tools that facilitate the application of products and technologies designed to enhance our customers’ producing formations.

Chapter 2 Fluid Planning: Fluid Selection

This chapter of the Engineered Solutions Guide for Clear Brine Fluids and Filtration is designed to take you through the decision making process and assist with the planning and development of a well completion project. It discusses safety and the environment, the planning process, fluid categories, fluid density, crystallization temperature, temperature and pressure effects, estimating fluid volume, and fluid compatibility.

The information in this chapter addresses needs that often arise in the field, including general density equations, brine volume calculations, weight up procedures, cutback calculations, mixing viscosified pills, spotting balanced pills, and slug calculations.

In addition to providing high quality completion fluids, TETRA strives to remain at the leading edge of technology by developing innovative products to meet the ever-changing needs of the industry. This chapter provides a quick reference for a number of the Company's more popular products.

In this chapter, you will find the most useful tables and formulas including units of measurement, common minerals and metals, useful conversion factors, annular velocity, and single salt fluid composition and blending tables.

This chapter is an introductory knowledge base regarding the safety and handling of CBFs in the U.S. and adjacent offshore waters and should be read carefully. Although it covers topics including CBF chemical constituents, brine handling and personal safety, and brine handling and disposal, it should in no way be considered exhaustive or the sole source of information.

Chapter 8 provides additional information on subjects mentioned throughout this guide. In this chapter, special topics of a critical nature are explored in more detail. They include: crystallization temperature, corrosion control, displacement, reduction of fluid loss, filtration and clarity.
