# equivalent density ### Equivalent Density definition - Law Insider

Equivalent Density means the mass of an optic per unit optical area projected onto the optical surface.sp.info Equivalent Circulating Density - an overview 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.sp.info Conversion Table:DensityConversion Table:Density. Unit Name. Relation to kilogram/cubic meter [kg/m3] grain/barrel [imperial] 3.95938E-4 [kg/m3] grain/barrel [US fluid] 5.434305E-4 [kg/m3]sp.info Material Calculator - Density of Mixed MaterialsPlease enter of each material two of the three values, the third value as well as total mass, volume and the density of the mix will be calculated. Density is mass per volume, a common unit is g/cm³. Then, mass is in grams, volume in cubic centimeters. The density of water is about 1 g/cm³. Here you can find the density of the chemical elements. ### Equivalent Circulating Density - Oil Well Drilling - Rig

Feb 06, 2021 · The equivalent circulating density is thought of as a static mud column from the selected location up to the surface which will create a pressure equal to the ECP. A mud which has a weight of 11.4 ppg is being circulated within a 9" by 5" annulus which is 15,000 feet long at a rate of 400 gpm.sp.info Equivalent Fluid PressureEquivalent fluid pressure (pcf) and wall design criteria is compared below.

It is generally used to indicate the increase in pressure exerted when circulating but it also indicates the increase or decrease in pressure caused sp.info Examples of Density for Substances & in Real LifeDensity Formula. Density is calculated according to the simple formula:p=M/v; That is, density (p) is equal to total mass (M) divided by total volume (v). This formula can be used to determine the density of any substance. Common units for the measurement of density include grams (g), milliliters (ml), or grams per cubic centimeter. ### New approach to evaluate the equivalent circulating

Oct 23, 2018 · The equivalent circulation density (ECD) is a very important parameter in drilling high-pressure high-temperature and deepwater wells. ECD is a key parameter during drilling through formations where the margin between the pore pressure and the fracture pressure (FP) is narrow. In these critical formations, the ECD is used to control the formation pressure and prevent kicks.sp.info Equivalent Circulating Density (ECD) Oil and Gas 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.
