This invention relates to a method of producing polymer spherical bodies and is to produce a large size spherical body having no residual strain. This method comprises suspending a liquid monomer in a supporting liquid having a magnetic susceptibility χ2 larger than a magnetic susceptibility χ1 of any one of the monomer and the resulting polymer and not dissolving substantially the monomer, and applying a gradient magnetic field to the supporting liquid to float droplets of the monomer at a given position in the supporting liquid, and polymerizing and solidifying the droplets while maintaining a state that the droplet is substantially shaped into a sphere through surface tension. This method is made possible to produce polymer spherical bodies capable of using in optical application and the like.

Methods and systems for acoustically determining reservoir parameters of subterranean formations. A tool comprising at least one seismic source or seismic receiver mounted thereon; a conveyance configured for movement of the acoustic tool in a borehole traversing the subterranean formations; and a source retainer configured or designed for permanent deployment in the borehole to removably retain the acoustic tool in the borehole. The source retainer when deployed provides acoustic coupling with the borehole and removably retains the acoustic tool in the borehole so that, over multiple deployments, the acoustic tool is repeatedly deployed at the same predetermined location and orientation relative to the subterranean formation, and with the same acoustic coupling to the borehole.
