Computes a map of equivalent densities
Computes a map of frictional pressure losses.
These methods calculate the pressure at a given depth, eg. when it is set the depth=0.0m and isAnnular = False the method returns the standpipe pressure. Normally this functionality is useful to compare pressure (at specific position) on Time Charts.
Computes the pressure at a given depth.
These methods calculate the ECD at a given depth, eg. when it is set the depth=bitdepth and isAnnular = True the method returns the Bottom ECD or ESD. Normally this functionality is useful to compare ECD and ESD (at specific position) on Time Charts.
Computes the equivalent density at a given depth
Maps components into their respective pressure drops.
Calculates the choke pressure based on a set point and measured depth of the set point
Calibrates frictional pressure loss on BHA from the linear and exponential parameters on adjustable components.
Parameters
Description
unit
wellId
Well Id
String
drillingSectionIndex
Drilling Section Index
String
runPosIndex
Run Pos Index
String
bitDepth
bit depth measured depth. Default is length of drill string
meters
fluidFlow
Flow Rate or pump flow in. Default is zero
m3/s
isAnnular
The pressure at the start of the portion specified at the {@link Hydraulics} creation, which determines the ({@link #integrationPath}). If startAnnular at {@link Hydraulics} construction is true, the portion is the annular one, tubular otherwise.
Boolean
entryPressure
The pressure at the integration path starts. Default zero.
Pa
startAnnular
This is MD of start annular (default = 0). When is the ‘return to seabed’ scenario this value is the water depth.
