  • Patent number: 8053394
    Abstract: A drilling fluid has a redispersible polymer powder introduced as a water dispersion that is capable of providing a deformable latex film on at least a portion of a subterranean sand formation and which inhibits or controls fluid loss and acts as a sealing agent when used to drill in sand formations for hydrocarbon recovery operations. The redispersible polymer powder may be made by drying the emulsion in which they are formed and then grinding into a powder or by spray drying. The polymer particles of suitable size precipitate or collect or assemble onto the pores of a subterranean sand formation to at least partial seal the formation with a deformable polymer film.

  • Publication number: 20110257274
    Abstract: The present invention has an objective to easily obtain an emulsion exhibiting superior storage stability, and in particular, an emulsion of a polyorganosiloxane. The present invention provides a method for producing an emulsion characterized by obtaining an emulsion by emulsifying a mixture of an oil and a surfactant, obtained by synthesizing the surfactant in the oil. In particular, the method is suitably used for the preparation of an emulsion of an organopolysiloxane (A) which is usually difficult to be stably emulsified. A silicone-based surfactant (B), and in particular, a silicone-based surfactant having a small degree of polymerization of a siloxane chain such as a trisiloxane is synthesized in an oil. Thereby, an emulsion exhibiting superior storage stability can be produced.

  • Patent number: 8013023
    Abstract: An emulsion including a continuous phase, a discontinuous phase which is immiscible in the continuous phase, and optionally a surfactant, the surfactant has a first part which is compatible with the continuous phase and a second part which is compatible with the discontinuous phase. The continuous phase has a high volume resistivity and the discontinuous phase is electrically charged. The discontinuous phase can be a reagent, a solvent which carries an active chemical reagent or a carrier liquid for a solid or insoluble liquid dispersed in the discontinuous phase. The surfactant, if present, is selected to not significantly reduce the volume resistivity of the continuous phase. The emulsion can also include a charge control agent. The emulsions can be used for the electrostatically controlled placement of matter in a spatially defined manner from the discontinuous phase for combinatorial chemistry and micrometer and nanometer scale deposition with or without reaction.
