The objectives of this project were to evaluate the effects rock- fluid reactions in typical oil-producing formations may have on the success or failure of enhanced oil recovery (eor) operations. Core samples were collected from a number of oil-producing formations that are undergoing or are potential candidates for eor operations. The mineralogical-petrographic characteristics of the cores were evaluated. The cores were then subjected to fluid-flow tests in which sequences of flowing fluids, which might be used in eor operations, were used to evaluate effects on flow capacity. Stabilizing agents were studied to determine their effectiveness in minimizing loss of flow capacity. Cores from formations in which steam injection operations are planned or were in progress were steamed to evaluate effects on rock behavior. Chemical loss studies were undertaken to evaluate rock-fluid reactions in chemical eor operations.
