phenol formaldehydewater shut-offA few wells from a major western India on-shore oil field are either on the verge of being shut in or have already been abandoned due to excessive water-cut (WCT) levels. Low injectivity and extreme temperatures (149掳C) make it difficult for water shut-...
Polyacrylamide and water-soluble phenol-formaldehyde resin can produce crosslinking reaction to generate the movable gel, which can be used in deep profile control to enhance oil recovery. In this paper, the preparation process of water-soluble phenol-formaldehyde resin crosslinking agent (polyhydroxyme...
