A set of numbered golf clubs made from a plurality of progressively lofted clubs, each club having a club head, a shaft fixed at one end to the club head, and a grip fixed to the shaft at the other end. A counterweight is positioned at the distal end of the golf club opposite the club head, and the length of the shaft and the weight of the head, the shaft, the grip, and the counterweight of each club are selected so that each club within the set has a lorythmic swing weight of less than A minus 6 points, each club preferably having a shaft of the same flexing properties. The club heads with the counterweight system provides the user with increased stability, control and power.

The dialkylbenzene polyethoxy alkyl sulfonate is combined with a water soluble petroleum sulfonate surfactant to form an effective surfactant solution that is stable in high salinity environments. The surfactant solution is injected into an underground petroleum reservoir in order to recover crude oil therefrom.
