Abstract
A treatment method for a hydrocarbon well includes placing a well treatment fluid containing a viscosifying agent in the well and, using the viscosifying agent, attaining a first viscosity of the fluid in the well. The method includes combining a porphyrin compound with the fluid and, using the porphyrin compound, decreasing viscosity of the fluid in the well to a second viscosity less than the first viscosity. A hydrocarbon well treatment fluid includes an aqueous carrier fluid, a polymer viscosifying agent, and a chlorophyll compound.
