    • 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.
    • 将封装的材料递送到地下环境以用于处理地下环境的方法具有以下步骤:(a)用选择用于处理地下环境的活性剂加载中空微管的内腔,其中中空微管是相容的 与地下环境; 和(b)将空心微管施用于地下环境,允许活性剂受控释放到地下环境中。 该方法可以使用中空微管的浆液来实施,其中这些微管的管腔装载有用于处理石油井环境的试剂,并且其中这些负载的微管分散在选自水性载体,非水溶性载体的液相载体中, 含水载体和水性和非水性材料的乳液。 也可以使用由装有一种或多种通常与粘合剂结合的活性剂的固体的小管制成的丸来实施该方法。
