Example Results From Baker Hughes Drilling Fluids ESD
Calculator
Using the ESD Calculator is very simple and requires only basic input information. There are three
categories for user input. They are as follows:
• Operational information,
• Salt information (Salt TCT is taken into account for mixed brines) , and
• Depth/temperature/brine composition information.
