1. A method comprising:
selecting an emulsion or a microemulsion composition for injection into a wellbore of a well based on a determination of whether formation crude oil is produced or whether formation gas is produced by the well,
wherein, when formation crude oil is produced by the well, the emulsion or the microemulsion composition is selected to comprise a terpene having a phase inversion temperature greater than 43° C., water, and a surfactant; and
wherein, when formation gas is produced by the well, the emulsion or the microemulsion is selected to comprise a terpene having a phase inversion temperature less than 43° C., water and a surfactant; and
injecting the emulsion or the microemulsion into the wellbore.
