Summary Recent advances in software and hardware technology have made possible the development of field-scale, fully compositional CO2-flood simulations capable of capturing areal variations in performance on an individual well basis. This paper firs

To demonstrate that cosurfactant-enhanced alkaline flooding is viable in recovering waterflood residual oil from sandstone reservoirs in the near-offshore Gulf of Mexico, a series of tests is being conducted in the White Caste field, Louisiana. The s

Summary A theory of 1D dispersion-free displacement in porous media is used toreveal features of floods in which three phases flow simultaneously. Theanalysis shows how the sequence of compositions realized in given classes ofproblems can be recogniz

Summary A theory of multicomponent, multiphase displacement in porous media is further developed for three-component, three-phase systems. In regions of a tie-triangle in which one or two of the phases is (are) immobile, the description of solutions

Abstract Laboratory results demonstrate that surfactant adsorption on sandstones is minimized and foam performance improved by reducing the ethoxylate chain length in alcohol ethoxy sulfonates and blending unethoxylated and ethoxylated sulfonates to

Abstract Gas-oil foam has been; observed at reservoir conditions in microvisual experiments, created in laboratory corefloods, and shown to have been responsible for CO2 and N2 mobility reduction in experiments. Gas-oil foam can increase oil recovery

Summary The stability of foam lamellae is limited by capillary pressure. Consequently, as the fractional flow of gas in a foam is raised at a fixed gas velocity, the capillary pressure in a porous medium at first increases and then approaches a chara

Summary The mobilities of aqueous foams of known texture have been measured in homogeneous bead packs. To correlate the data, a theory developed recently to describe the apparent viscosity of foams in smooth capillaries is extended to account for (1)

Summary. Field tests suggest that a steam-foam drive is more effective when nitrogen, methane. or the like is added to the formulation. A plausible explanation is that foam lifetime is longest when transport of noncondensable gas limits mass transfer

Summary The mobility of a foam depends heavily on its texture, which is the distribution of bubble sizes in the dispersion. To incorporate this variable in a mechanistic simulator, the usual conservation equations are coupled with balances on the den
