A method for delivering encapsulated materials to a subsurface environment, for the treatment of the subsurface environment, has the steps of a loading the lumen of hollow microtubules with an active agent selected for treating the subsurface environment, where the hollow microtubules are compatible with the subsurface environment and b administering the hollow microtubules to the subsurface environment, permitting the controlled release of the active agent into the subsurface environment. This method may be practiced using a slurry of hollow microtubules, where the lumen of these microtubules is loaded with an agent for the treatment of petroleum well environments, and where these loaded microtubules are dispersed in a liquid phase carrier selected from aqueous carriers, non-aqueous carriers, and emulsions of aqueous and non-aqueous materials. This method may also be practiced using a pill made of a consolidated mass of tubules loaded with one or more active agents, typically bound with a binder.
