摘要: An electro-chemical sensor is described having two molecular redox systems one being sensitive the other insensitive to the species to be detected and both being covalently bound to a polymer and having a detector to detect relative shifts in the voltammograms of the two redox systems.

摘要: This invention relates to the synthesis and use in oilfield applications of copolymers which can undergo the Diels-Alder reaction to form a gel. Under appropriate conditions, the retro Diels-Alder reaction can take place to provide for decreasing the viscosity of the aforementioned gel.

摘要: 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.
