A comprehensive Material Balance Program

Material Balance Analysis and ForecastingT ANK

Tank is a powerful analytical tool for reviewing and predicting the performance of combination drive oil and gas reservoirs. Tankcouples a general form of the material balance equation with a choice of analytical aquifer models, allowing it to handle a widerange of hydrocarbon fluid types and reservoir drive mechanisms. Given a reservoirs performance history, Tank can be used toestimate original hydrocarbons in place and aquifer size and strength. Once these parameters have been quantified, Tank may beused to review and redict reservoir and a uifer erformance usin a variet of anal tical techni ues.

Programs available for customization and implementation

Beampump, Bubblemap,Patternflood, and Wellbore

Patternflood: A map based plotting and material balance packagethat balances voidage, influx, injection, and fluxthrough a fields waterflood patterns. Although datainput is significant, resulting pattern balancingresults can be used to more efficiently managewaterflood injection and withdrawal. The functionalityin this program is superseded by both DSS and OFM.
