❿Duringanunderbalancedoperation,bothliquidandgasmaybeinjectedintothewellascirculatingfluids.Duetotheunderbalancedconditionofthewellbore,formationgas,oil,andwatercouldflowintothewellbore.Inaddition,solidparticles（cuttings）arealsoflowingwithallthefluidsinthewellboreannulus.Theinteractionsbetweenthesecoexistingfluidsandcuttingparticlesrequirespecialtreatmentduringthehydrauliccalculations.

❿Duetothedifferenceinhydraulicproperties（density,viscosity,andcompressibility）amongthecoexistingphases,theydonotflowatthesamespeed.Thesephasescanflowwith

variousflowpatterns（bubbleflow,mistflow,slugflow,wavyflow,annularflow,etc.）.Flowpatternsaffectnotonlytheflowingmixturedensityanditsfractionalpressureloss,butalsotheefficiencyofcuttingtransportation.❿Phasechangebetweenliquidandgasphasescanoccuralongtheflowpathofanunderbalancedoperation.Duetothevariationofpressureandtemperaturealongtheflowpath,gasmayvaporizefromliquidhydrocarbonsorotherliquidfluids,andliquidcouldcondensefromgasphases.Phasechangewouldalternotonlytheratioofliquidandgasphasesinthewellborebutalsotheirproperties.Itcouldhavesignificanteffectsontheflowpattern,bothgravityandfrictionpressureloss,andthecuttingcarryingcapacityofthecirculatingfluids.

AboutHUBS

ThisHydraulicUnderBalancedSimulator（HUBS）wasdesignedtoperformhydrauliccalculationsforunderbalancedoperations.Hydraulicdesignisthekeytothesuccessofanunderbalancedoperationbecause:
