... and the contact angle of a crude oil drop on a reservoir rock in several aqueous solutions. Based on the modern digital image acquisition, analysis and processing techniques, the ADSA technique obtains the accurate digital image of the sessile oil drop and accomplishes the relevant measurements. The aqueous...

.... The adhesion tests further demonstrated that an oil drop could adhere to the crystal surface even after the heavy ends (like asphaltenes) had precipitated within the oil drop away from the interface. This indicated that the heavy ends may not be solely responsible for the interfacial adhesion effects...

... The interaction between surfactant slug and trapped oil drop reveals some fundamental properties of mass transfer processes in pore scale geometry and at reservoir velocities. Although C1 could solubilize nonane in ratios of about 1 kg nonane to 9 kg Cl, there was little evidence...
