Compositions comprising non-halogenated solvents for use in various aspects of a life cycle of an oil and/or gas well, and related methods, are provided. In some embodiments, the composition comprises a solvent blend and one or more surfactants. In some embodiments, the solvent blend comprises a first type of solvent (e.g., a terpene) and a second type of solvent (e.g., a non-halogenated solvent). The composition may comprise about 90 wt% to 99.9 wt% of the solvent blend, and about 0.1 wt% to 10 wt% of one or more surfactants, versus the total weight of the composition. In some embodiments, compositions can be used in methods for treating an oil and/or gas well, having a wellbore that comprises one or more fluids. A composition may be delivered into the wellbore, passing through the one or more fluids to reduce residues comprising asphaltenes, paraffins or combinations thereof on or near the wellbore.

Compositions comprising aromatic ester solvents for use in various aspects of a life cycle of an oil and/or gas well, and related methods, are provided. In some embodiments, the composition includes an emulsion or microemulsion wherein the emulsion or microemulsion comprises an aqueous phase, a surfactant, and a non-aqueous phase. In some embodiments, the non-aqueous phase comprises a solvent blend including a first type of solvent and a second type of solvent, e.g., having a respective weight ratio of about 3:2 to 1:4. In some embodiments, the first type of solvent is a terpene and/or the second type of solvent is an aromatic ester solvent. In some embodiments, compositions are used in methods for treating an oil and/or gas well having a wellbore. In some embodiments, the composition is delivered into the wellbore, reducing residues comprising kerogens, asphaltenes, paraffins, organic scale, or combinations thereof on or near the wellbore.
