A polysulfone-zeolite composite membrane can be used to separate gas pairs such as hydrogencarbon dioxide. Metallic plated layers are formed on the electrodes of the semiconductor chip. The plurality of holes provides electromagnetic shielding. An output and input module are coupled to the socket contacts. The first lens is mounted on the metal light reflection layer for encapsulating the LED chip. The work string includes a first tool comprising a port providing fluid communication between an interior space of the first tool to an exterior space to permit placement of a plug in a wellbore.
