Abstract: Provided herein include a degradation-promoted polymer and a method for making the degradation-promoted polymer. The degradation-promoted polymer has a composition containing one or more polymers and a degradation-promoting agent that includes Lactide and an organic acid. The organic acid may include at least one of succinic acid, levulinic acid, and lauric acid. The degradation-promoting agent can promote and control the degradation of the polymer in aqueous-based environments having different temperatures, pressures depths, and aqueous solutions. The method includes mixing a polymer with a degradation-promoting agent to produce a degradation-promoted polymer. Application for such degradation-promoted polymer can include but not limited to such as for example a process for opening new oil well, oil well work-over, or oil well cleanout, in which each well may have a different temperature and may require a different degradation rate of the polymer.
