equivalent circulating density - Schlumberger Oilfield

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 (),P is the pressure drop in the annulus between depth D and surface (psi),and D is the true vertical depth (feet).The ECD is an important parameter in What is equivalent static density in drilling? - QuoraJul 08,2018 Equivalent Density#0183;In drilling,mud weight is a critical parameter.The mud weight is used to exert hydraulic pressure on the rock formations were drilling through,in order to counteract the fluid pressure in said rocks.The mud weight,once mixed,is affected by What is Snow Water Equivalent?
