According to one aspect, a system is adapted to actively control one or more operating parameters associated with: a wellbore extending in a subterranean formation, and/or wellbore fluid flowing out of the wellbore via a wellhead. The system includes one or more sensors; an electronic controller adapted to receive from the one or more sensors measurement data; and a valve through which the wellbore fluid is adapted to flow. The valve is adapted to be in communication with the electronic controller. The active control of the at least one of the one or more operating parameters is adapted to facilitate: maintenance of the integrity of the wellbore, and/or enhancement of oil and/or gas production out of the wellbore. In one embodiment, the wellbore fluid flow is frac flow-back. In another aspect, a system is adapted to monitor vent gas separated from wellbore fluid flowing out a wellhead.

The present invention is a process for uniformly depositing nanomaterials having particles smaller than 1 &#x3bc;m (i.e., nanoparticles) onto a surface of a base material (substrate or surface). The process is used to deposit any solid (nanoparticle) of any shape such as nanofibers, nanotubes, nanoclays (e.g., platelet shaped), nano-spheres, or irregularly shaped granules. The base material upon which the nano-particles are deposited can be made of any material. The method substantially prevents the deposition on the base material of larger particles (contaminants or clusters of the nanoparticles) which are often mixed with the nanomaterials. The amount of deposition and the range of particle sizes to be deposited can also be controlled by this method. Maintaining deposition uniformity, controlling the amount of deposition, and the elimination of larger particles enhances the utility of nanomaterials, and by subsequent processing, enables the development of multifunctional composite materials (or other coated substrates) to be used in commercial applications. In the present invention nanoparticles are applied to other base materials by substantially eliminating deposition of larger clusters or aggregates of nano-sized materials or other large impurities of other materials upon or in the base materials by positioning the base material within an upper portion of a deposition chamber.
