Hydrophobization of bottom-hole area in hydrophilic reservoirs

Reviewed are the problems of hydrophobization of silted reservoirs within o il bearing objects at the fields of West Siberia region. Positive influence of cation-active surf acta nts during bottom-hole areas treatments, due to loose-bond water removal and acid stimulation coverage increase, is determ ined. Proposed are the directions for further scientific studies of hydroph obization processes in hydrophylic reservoirs with the purpose to enhance o il recovery from productive formations.
