This five-day course covers the reservoir engineeringaspects of waterflooding. The seminar combines geology,rockandfluidproperties,andimmiscibledisplacementtheorytodevelopwaterfloodingpredictiontechniquesandtoaidinthe evaluation of actual waterflood performance behavior.Detailedpredictionsofoilandwaterproducingrates,waterinjection rates, and recovery efficiency (areal, vertical, anddisplacement), and an analysis of other variables whichcontrol recoveryefficiencyare included.Alsodiscussedarewaterfloodsurveillancetechniquessuchasproductionplots,WORanalysis,floodableporevolumeversusprimarydepletionpore volume, injection profile testing, pressure transienttesting,step-ratetesting,Hallplots,patternbalancing,bubblemaps,volumetricsweepevaluation,andinjectionefficiencydetermination. These surveillance techniques provide the
