Abstract	:	The influence of surfactants on the surface charge behavior of carbonate rocks was investigated. Static and dynamic adsorption studies were conducted for one anionic and two nonionic surfactants onto carbonate rocks. The interaction of brine with the rock surface and the nature of the interaction between the surfactant and the carbonate rock were analyzed through zeta potential studies. The effects of temperature and brine composition on static adsorption density were also studied. The nonionic surfactant Triton X-102 presented the lowest adsorption level and the highest desorption level at a temperature of 107 and a salinity of 57000 ppm synthetic brine. The adsorption of B1083 at different salinities and temperatures can be compared relatively well to the measurements of zeta potential.
