    • Methods of determining the wettability of a surface under predetermined conditions, wherein the surface simulates or is a downhole surface for use in an oil or gas operation. The methods include the steps of: (A) contacting the surface with at least a first fluid; and then (B) observing the surface for the presence or absence of a marker to determine the wettability of the surface. According to a first aspect of the inventions, the first fluid comprises a first marker, and the step of contacting is under first predetermined conditions. This aspect also includes the additional step of contacting the surface with a second fluid comprising a second marker. According to a second aspect of the inventions, the step of contacting the surface with the first fluid is under predetermined conditions, and the surface is contacted with a second fluid comprising a second marker. According to a third aspect of the inventions, the first fluid comprises a first marker, the surface is contacted with a second fluid comprising a second marker, and both steps of contacting are performed under predetermined conditions.
    • 在预定条件下确定表面的润湿性的方法,其中表面模拟或用于油或气操作中的井下表面。 所述方法包括以下步骤:(A)使所述表面与至少第一流体接触; 然后(B)观察表面存在或不存在标记以确定表面的润湿性。 根据本发明的第一方面,第一流体包括第一标记,并且接触步骤处于第一预定条件下。 该方面还包括使表面与包含第二标记的第二流体接触的附加步骤。 根据本发明的第二方面,使表面与第一流体接触的步骤处于预定条件下,并且表面与包含第二标记的第二流体接触。 根据本发明的第三方面,第一流体包括第一标记,表面与包含第二标记的第二流体接触,并且在预定条件下进行两个接触步骤。
