Paper presented at the SPE Improved Oil Recovery Conference, August 31–September 4, 2020
Paper Number: SPE-200323-MS
.... Surfactant and alkali breakthrough in HASP were later than VASP. The time of first scaling producer wells in HASP was later than that in VASP. Discussion Planned chemicals injection scheme of HASP was the same to that of VASP. The ASP flooding application in Daqing oilfield was well summarized...

... several immiscible nitrogen injection schemes and to investigate how rock-fluid and fluid-fluid interactions control the immiscible flooding process. Well-controlled core-flood experiments were performed in Bentheimer sandstone cores. Nitrogen was injected into cores saturated with n-hexadecane at connate...

... number of cycles, a pilot project to assess the feasibility of injecting nitrogen accompanied cyclic steam was raised. The determination of optimum volumes and injection scheme by numerical simulation was performed in a sector model. Eleven schemes of steam plus nitrogen injection were evaluated. In all...

Paper Number: SPE-169086-MS
... Abstract This paper presents a new method for generating dimensionless CO 2 flood forecast prototypes for various injection schemes from an existing prototype. Given an existing prototype, the method described in this paper can predict an appropriate prototype for an alternating injection...

... for economic evaluation and to design an optimum surfactant injection scheme. Results show that lignosulfonate could reduce the adsorption of a primary foaming agent by 24–60% in Berea sandstone and 15–29% in Indiana limestone core samples. The selective adsorption behavior of lignosulfonate and surfactant...
