...-time data. Consequently, conventional semilog or type-curve analyses are difficult to perform. Because of dominating influence of inner and outer boundary conditions, an appropriate interpretation model is necessary for the estimation of reservoir parameters. This work presents analytical models...

... of the first front. The time of such deviation for a given system is indicative of the distance from the wellbore to the front. The dimensionless time of deviation, delta tDf1 *, for many reservoir situations is frequently assumed to be constant. The equation (1) is then used to estimate the distance...
