摘要： A plug used in the hydraulic fracking of hydrocarbon wells. The plug, known as a frac or bridge plug, contains one or more containers housing a chemical substance such as a solid, liquid, or gel composition. The composition may constitute or include a cleaning agent, friction reducer, suspending agent, or other wellbore additive. For example, the composition may constitute or include epoxy components, resins, thermoplastics, dry add friction reducers, dry add gel, dry add pipe on pipe, similar agents, or any combination thereof. The containers can include the same chemical substance or a variety of chemical substances. During drill out of the plug, the containers rupture and release the chemical substance into the wellbore. The released chemical substance, if a cleaning agent, assists in the cleaning of the milled-plug pieces from the wellbore.
