Abstract
Video fixation of the growth of methane hydrate in three-phase water–oil–methane systems was carried out. Three kinds of crude oil were taken for experiments. The formation of unusual associates of gas hydrate with oil, growing into the volume of the aqueous phase, was found to be possible in two of these oil kinds at the late stages of hydrate growth. Possible mechanisms for the formation of these associates are discussed.
