| Summary |
"An analysis of the principal theories concerning the transient movement of water in artesian aquifers and from artesian aquifers into hydrocarbon reservoirs is presented. Various analytical methods which can be applied to depict the behavior of these two types of aquifer systems are compared. Most aquifer studies to date have been based upon the Thesis Non-Equilibrium Formula. This equation has been used to calculate the coefficients of storage and transmissibility for aquifers; to evaluate well performance; and to investigate problems concerning recharge, movement, and discharge of aquifer water. However, one problem which still remains is that of accurately predicting the recharge volumes which supply the reservoir drawdown area under the effects of pressure decline. The present study suggests a possible means of accurately determining recharge volumes by the application of the Van Everdingen-Hurst Laplacian solution to the radial diffusivity equation for transient water movement. This solution would be based upon the withdrawal rates, cumulative withdrawals, and aquifer pressure profiles"--Abstract, leaf ii. |
