Embodiments of the present invention provide systems and methods for detection and/or measurement of gaseous components of multiphase mixtures containing one or more hydrocarbons that may be retrieved down a wellbore or may be being transported in a pipeline. More specifically, but not by way of limitation, embodiments of the present invention may provide for separation of the gaseous components from the multiphase mixtures and detection and/or measurement of the separated gaseous components by direct oxidation or reduction.

System and method for qualitative and quantitative analysis of gaseous components of multiphase hydrocarbon mixtures

A subterranean location accessed via a wellbore is treated with an oilfield fluid containing a viscosifying agent which is a polymer and a cross-linking agent which can undergo the Diels-Alder reaction to form a gel. Conditions at the subterranean location alter fluid viscosity by bringing about the Diels-Alder reaction to increase viscosity or the retro Diels-Alder reaction to decrease the viscosity of the gel.

Reversible polymeric gelation for oilfield applications

A viscosifying agent for wellbore fluids is described including a polymer polymerized using at least two pre-polymers 'A' and 'B', the polymer being capable of essentially fully degrading into soluble fragments after the initiation of a breaking process.
