Abstract: An method for analyzing a fluid comprises collecting a sample of the fluid and exposing the fluid sample to a light of a predetermined wavelength at a predetermined modulation frequency. An acoustic signal caused by the interaction of the light and the fluid sample is sensed, and the sensed acoustic signal is related to at least one component of the fluid.

Abstract: An apparatus for analyzing a fluid comprises a chamber to receive a fluid sample. A pump reduces a pressure in the chamber below a vapor pressure of a component of the fluid sample. At least one light system provides a light at a predetermined modulation frequency to the fluid sample. An acoustic sensor detects an acoustic signal caused by the interaction of the light and the fluid sample. A controller relates the acoustic signal to at least one chemical component of the fluid sample.

Abstract: Of the many compositions and methods provided herein, one method includes a method of preventing emulsification of crude oil into an aqueous-based treatment fluid, comprising: contacting crude oil in a well bore with the aqueous-based treatment fluid comprising a styrene-acrylate copolymer, wherein the crude oil has an API gravity of about 10 or greater; and allowing the styrene-acrylate copolymer to interact with the crude oil in the well bore.

Abstract: Of the many compositions and methods provided herein, one method includes a method comprising: contacting tar resident in a well bore with a treatment fluid comprising a styrene-acrylate polymer; and allowing the styrene-acrylate polymer to interact with the tar to at least partially reduce the tendency of the tar to adhere to a surface. Another method provided herein includes a method for treating tar sand comprising: contacting the tar sand with a treatment fluid comprising an aqueous fluid and a styrene-acrylate polymer, the tar sand comprising tar and sand; and allowing the styrene-acrylate polymers to interact with the tar to at least partially separate the tar from the sand.
