Estimate near-wellbore permeability, formation permeability, and flow efficiency. Note from the table that all data lie in the range of 1-1000 minutes, so need to choose the corresponding type curve.
Type curves provide a powerful method for analyzing pressure drawdown (flow) and buildup tests. Fundamentally, type curves are preplotted solutions to the flow equations , such as the diffusivity equation, for selected types of formations and selected initial and boundary conditions. Visa mer The solutions plotted on type curves are usually presented in terms of dimensionless variables. To review dimensionless variables, consider theEi-function solution to … Visa mer Gringarten et al.presented a type curve, commonly called the Gringarten type curve, that achieved widespread use. It is based on a solution to the radial diffusivity equation and the following assumptions: vertical well with … Visa mer The shapes of drawdown and buildup type curves are different, as Fig. 6 illustrates. In this simplified case, in which wellbore storage distortion is … Visa mer The derivative type curve proposed by Bourdet et al. eliminates the ambiguity in the Gringarten type curve.
