Equivalent Circulating Density (ECD) Equivalent circulating density is the effective density of the circulating fluid in the wellbore resulting from the sum of the hydrostatic pressure imposed by the static fluid column and the friction pressure.

What is dynamic equivalent density?The equivalent circulating density at any point accounts for the sum of hydrostatic pressure of a column of fluid and frictional pressure loss above that point. Thus, at any point of interest, the dynamic equivalent density, ECD, is higher than the static equivalent mud density, EMD. The ECD is calculated as (2.3) E C D = E M D + Δ P K × T V DSee all results for this question

equivalent circulating density | Oilfield Glossary

equivalent circulating density. 1. n. [Drilling Fluids] The effective density exerted by a circulating fluid against the formation that takes into account the pressure drop in the annulus above the point being considered. The ECD is calculated as: d + P/ (0.052*D), where d is the mud weight ( ppg ), P is the pressure drop in the annulus between depth D and surface (psi), and D is the true vertical depth (feet).What is the equivalent density of fluid flow?The equivalent circulating density or dynamic density at any time during fluid flow is always greater than the static mud density when flow is stopped. To understand why this is so, consider this; the mud pumps supply the pressure that forces drilling mud down the drillstring to the bottom of the hole and up again to the surface.See all results for this questionWhat is equivalent circulating density?Equivalent circulating density (ecd): The increase in bottomhole pressure expressed as an increase in pressure that occurs only when mud is being circulated.See all results for this question

Equivalent Density - an overview | ScienceDirect Topics

The common range of rock overburden pressure, in equivalent density, varies between 18 and 22 ppg (2.172.64 SG). This range would create an overburden pressure gradient of about 1 psi/ft (22.7 kPa/m). (The 1 psi/ft is not applicable for shallow marine sediments or massive salt.) The overburden pressure is not a fluid-dependent pressure.Equivalent Circulating Density ECD ppg - Formulas and equivalent densityEquivalent Circulating Density ECD ppg.
