Overbased branched chain aliphatic sulfonate waterflood additives |
| abstract |
Overbased branched chain aliphatic sulfonates are prepared by adding an excess of a base component such as an alkali metal hydroxide, ammonium hydroxide, or an alkali metal carbonate to a sulfonate derived by sulfonating a branched chain alkene such as a propylene tetramer and neutralizing the sulfonic acid thus formed with the base component. The overbased sulfonate is injected into a petroliferous formation to improve a water flood operation. In one embodiment overbasing base component is injected as a slug subsequent to injection of the sulfonate. |
