ECD In Drilling | What is, How To Calculate & Control
ECD / Equivalent Circulating Density is an important parameter to monitor in the drilling process of a well, especially in horizontal & HPHT wells. In this article, our objective is as following: ECD Definition, the calculations & formula of theoretical ECD in Drilling & to explain the parameters that influence ECD. you can also download the ECD calculation spreadsheet at the end of the article.

Why do we need to control the ECD In Drilling?
