Abstract: A unitary head cover for a set of golf irons includes a body portion having a length, a width, a first end and a second end. The first end is opposite the second end along the length of the body portion. The body portion has a first side and a second side opposite the first side. A plurality of pockets is spaced about the length of the body portion from the first end to the second end. The pockets may be spaced successively on the body portion, alternating between the first side and the second side. Each of the pockets is progressively sized and dimensioned to receive a head of a golf iron therein.

Abstract: Methods that include a method comprising providing a hydrocarbon-acid emulsion composition that comprises an acid phase, a hydrocarbon blend phase, and an emulsifying agent; and placing the hydrocarbon-acid emulsion composition in a subterranean formation. In some embodiments, the hydrocarbon blend phase comprises at least about 65% hydrocarbons having from six carbons (C6) through eleven carbons (C11). In other embodiments, the hydrocarbon blend phase has a flash point greater than about 100° F. Additional methods are also provided.
