    Abstract: A downhole separator has a housing defining an interior cavity divided into a first chamber and a second chamber by a flow restricting bearing housing. A shaft driven impeller pumps production fluid into the first chamber and to the bearing housing. The bearing housing generates a pressure drop in production fluid entering the second chamber, separating gas from liquid. A vortex generator in the second chamber segregates the liquid to the outside and the gas to the inside of the second chamber. A downhole separation method includes pumping production fluid into a first chamber, and generating a pressure drop in the fluid as the fluid enters a second chamber to separate gas and liquid.

    Abstract: The present invention provides a water continuous dispersion of nanoparticles. The water continuous dispersion includes: one or more aromatic amide anesthetic compounds; one or more polyethoxylated high HLB surfactants; one or more low HLB surfactants; one or more oils, wherein one or more nanoparticles of a dispersed phase include a lipid bilayer, and wherein ratio of oil to surfactant is between about 0.12:1 to about 3.5:1. Methods of preparing various water continuous dispersion of nanoparticles are also provided.
