Title:ANovelApproachtoCalculateWaterfloodOilRecoveryEfficiencyinHighWater-CutPeriodinOilReservoirs
Abstract:
Waterfloodingisaneffectivemethodusedinthesecondaryrecoveryofoilfields.However,theefficiencyofwaterfloodingtendstodecreaseasthewatercutinthereservoirincreases.Therefore,itisimportanttodevelopnewmethodstoevaluatetheoilrecoveryefficiencyduringthehighwater-cutperiod.Thispaperpresentsanovelapproachtocalculatethewaterfloodoilrecoveryefficiencyinhighwater-cutperiodsusingadvancedreservoirmodelingandsimulationtechniques.
Introduction:
Waterfloodingplaysasignificantroleinenhancingsecondaryoilrecoverybydisplacingoilfromthereservoirusinginjectedwater.However,asthewatercutincreasesintheproducedfluidsduringwaterflooding,theefficiencyofoilrecoverydecreases.Itiscrucialtodevelopanewmethodtoaccuratelyevaluatetheoilrecoveryefficiencyduringthehighwater-cutperiod.Thispaperproposesaninnovativeapproachthatcombinesreservoirmodelingandsimulationtechniquestocalculatethewaterfloodoilrecoveryefficiency.
Methodology:
1.ReservoirCharacterization:Accuratereservoircharacterizationisessentialforreliablesimulationresults.Thisstepinvolvesgatheringdataonthegeological,petrophysical,andfluidpropertiesandconductingathoroughanalysisofthewaterfloodedreservoir.
2.HistoryMatching:Thesimulationmodeliscalibratedtomatchthehistoricalproductiondata.Thisprocessverifiestheaccuracyofthereservoirmodelandensuresthatthesimulationsrepresenttheactualreservoirbehavior.
3.PredictionofReservoirBehavior:Usingthecalibratedreservoirmodel,simulationsareconductedtopredictthefuturebehaviorofthereservoirduringthehighwater-cutperiod.Theinputstothesimulationincludeinjectionrates,productionrates,andotherrelevantreservoirparameters.
