Abstract

The knowledge of specific mass of drilling fluids are of great importance in defining the characteristics of them during drilling wells. In the present work, the specific mass of distilled water was carried out in a PVT (Pressure-Volume-Temperature) cell using the Constant Composition Expansion procedure under high pressure and high temperature. Results showed a good agreement with literature valures.

Highlights

Concerning drilling wells, it is very important for the safety throughout the operation to prevent the occurrence of kicks or more dangerous situations, such as blowout
The specific mass tests of the distilled water were conducted in a PVT cell (Schlumberger) by the Constant Composition Expansion (CCE) procedure[2]
This procedure consists of the expansion of a fluid under constant temperature, either pure or mixture, through the application of constant pressure gradients

Summary

Introduction

Concerning drilling wells, it is very important for the safety throughout the operation to prevent the occurrence of kicks or more dangerous situations, such as blowout. Drilling fluids are the key to ensure the safety of drilling oil wells because it must exert hydrostatic pressure over the reservoir during drilling[1]. It is important to know their properties and their interaction with the gases found in the petroleum reservoirs. One of the main property that it should be known is the specific mass of the drilling fluid, which can be measured through a PVT (Pressure-VolumeTemperature) cell[2].
