Patent number: 7838467Abstract: Single phase microemulsions improve the removal of filter cakes formed during drilling with oil-based muds (OBMs). The single phase microemulsion removes oil and solids from the deposited filter cake. Optionally, an acid capable of solubilizing the filter cake bridging particles may also be used with the microemulsion. In one non-limiting embodiment the acid may be a polyamino carboxylic acid. Skin damage removal from internal and external filter cake deposition can be reduced. In another optional embodiment, the single phase microemulsion may contain a filtration control additive for delaying the filter cake removal, destruction or conversion.Type: GrantFiled: May 4, 2010Date of Patent: November 23, 2010Assignee: Baker Hughes IncorporatedInventors: Thomas A. Jones, David E. Clark, Lirio Quintero

Patent number: 7772287Abstract: A process and apparatus for rapidly producing an emulsion and microcapsules in a simple manner is provided wherein a dispersion phase is ejected from a dispersion phase-feeding port toward a continuous phase flowing in a microchannel in such a manner that flows of the dispersion phase and the continuous phase cross each other, thereby obtaining microdroplets, formed by the shear force of the continuous phase, having a size smaller than the width of the channel for feeding the dispersion phase.Type: GrantFiled: November 28, 2005Date of Patent: August 10, 2010Assignee: Japan Science & Technology AgencyInventors: Toshiro Higuchi, Toru Torii, Takashi Nishisako, Tomohiro Taniguchi

Publication number: 20100179230Abstract: The present invention provides microsphere manufacturing method and apparatus capable of stable obtaining microspheres of a desired size and reducing facility cost. According to the method and the apparatus, to manufacture microspheres made of a second liquid in a first liquid, the first liquid is supplied into a first channel to flow therein and the second liquid is supplied to an intermediate part of the first channel through a second channel. The supply velocities of the first and second liquids are set such that the second liquid closes the first channel and the closing part of the second liquid is cut off due to a pressure difference between an upstream side and a downstream side to form microspheres.Type: ApplicationFiled: May 28, 2009Publication date: July 15, 2010Applicant: Kabushiki Kaisha Kobe Seiko Sho (Kobe Steel,Ltd.)Inventors: Hiroyuki BAN, Koji NOISHIKI, Kazuto OKADA, Seiichi YAMAMOTO
