Abstract
Implementations described and claimed herein provide systems and methods for determining surfactant impact on reservoir wettability. In one implementation, a nuclear magnetic resonance Tmeasurement of a sample is obtained before surfactant imbibition is applied to the sample, and a second nuclear magnetic Tmeasurement of the sample is made after forced imbibition of the surfactant. Moreover, another nuclear magnetic resonance Tmeasurement (e.g., omitting surfactant imbibition) can be obtained simultaneously with the nuclear magnetic resonance Tmeasurement using a twin core sample. The nuclear magnetic resonance Tmeasurement and the nuclear magnetic resonance Tmeasurement are captured under simulated reservoir conditions. A fluid typing map is generated using the nuclear magnetic resonance Tmeasurement and the nuclear magnetic resonance Tmeasurement. An impact of the surfactant on fluid producibility is determined based on the fluid typing map.
