A wellbore fluid composition effective to reduce oil-containing residue and water wet wellbore surfaces is provided. The fluid composition comprises a terpene composition and a surfactant. Methods for use of the fluid composition as a single spacer or as a multiple spacer in conjunction with a second fluid are provided. Methods for use of the composition in reduction or removal of oil-containing residue from wellbore surfaces, as a clean-up fluid, in wellbore completions, as a displacement fluid, and in wellbore treatment are provided.

The air sampler according to claim 17, wherein said main body air vortex creates a low pressure area in a central part of said main body air vortex; wherein said liquid inlet means comprises a liquid inlet port; and wherein said liquid inlet port is located in said low pressure area; and wherein said low pressure area aspirates said stripping liquid into said main body through said liquid inlet port. 20. An air sampler; wherein said air sampler is adapted to strip a target material from an air flow with a stripping liquid; wherein said air sampler comprises: a main body means comprising a main body, a main body inner surface and a main body air chamber, wherein said main body inner surface defines said main body air chamber; wherein said main body air chamber is located within said main body; wherein said air sampler further comprises an air inlet means for permitting said air flow to enter said main body air chamber; an air outlet means for permitting said air flow to exit said main body air chamber; a liquid inlet means for permitting said stripping liquid to enter said main body air chamber; a liquid outlet means for permitting said stripping liquid to exit said main body air chamber; wherein, during operation of said air sampler, said main body means is for forming said
