Device For Improving Oil And Gas Recovery In Wells

View page
US Patent:
7051817, May 30, 2006
Filed:
Aug 9, 2004
Appl. No.:
10/914026
Inventors:
Vladimir M. Shaposhnikov - Brooklyn NY, US
Leonid Levitan - Brooklyn NY, US
Assignee:
Sorowell Production Services LLC - Waloon Lake MI
International Classification:
E21B 43/00
US Classification:
166372, 166 68, 166370
Abstract:
A device for improving recovery of hydrocarbons through a well by creating, regulating and maintaining under the device a calculated bottomhole pressure at a desired level and creating above the device a two-phase gas-liquid homogenous flow for efficient lifting of hydrocarbons to a surface, the device has a body having a central throughgoing opening with a shape corresponding a shape of a Laval nozzle and with a cross section which changes steplessly and gradually, and a mandrel attachable to a tubing and associated with the body without interfering with a flow of fluids.

Method Of And System For Production Of Hydrocarbons

US Patent:
7147058, Dec 12, 2006
Filed:
Aug 9, 2005
Appl. No.:
11/199781
Inventors:
Vladimir Shaposhnikov - Brooklyn NY, US
Leonid Levitan - Brooklyn NY, US
Vyacheslav Slavin - Berlin, DE
Josef Gaportsin - Brooklyn NY, US
Assignee:
Sorowell Production Services LLC - Waloon Lake MI
International Classification:
E21B 43/16
US Classification:
166370, 166 68, 166105, 166372
Abstract:
For production of hydrocarbons with high and medium gas-oil ratio from a well with a wellhead and a bottomhole communicating with a formation, and with a casing and a tubing located inside the casing and forming a space therebetween, steps are performed and means are provided for establishing a flow of hydrocarbon-containing fluid inside the tubing from the bottomhole to the wellhead, introducing gas into the space between the casing and the tubing so that the gas passes into the tubing and enhances the flow of the hydrocarbon-containing fluid from the bottomhole to the wellhead with simultaneous reduction of pressure in the bottomhole resulting in an increase of a pressure differential between the formation and the bottomhole; and introducing in the bottomhole a device which increases the pressure in the bottomhole so that the pressure differential between the formation and the bottomhole decreases and therefore a gas blockage in a near bottomhole zone of the formation is reduced to maintain an oil flow from the formation into the bottomhole.

Device For Improving Oil And Gas Recovery In Wells

US Patent:
7287597, Oct 30, 2007
Filed:
May 30, 2006
Appl. No.:
11/442896
Inventors:
Vladimir M Shaposhnikov - Brooklyn NY, US
Leonid Levitan - Brooklyn NY, US
Walter Breidenstein - Boyne Falls MI, US
Assignee:
Sorowell Production Services LLC - Wallon Lake MI
International Classification:
E21B 43/00
US Classification:
166372, 166 68
Abstract:
A device for improving recovery of hydrocarbons through a well is provided. The device creates, regulates and maintains a calculated bottomhole pressure at a desired level and creating above the device a two-phase gas-liquid homogenous flow for efficient lifting of hydrocarbons to a surface. The device has a body having a central through-going opening with a shape corresponding to a shape of a laval nozzle and with a cross section which changes steplessly and gradually, and a mandrel attachable to a tubing and associated with the body without interfering with a flow of fluids.

Petrophysical Fluid Flow Property Determination

View page
US Patent:
7472588, Jan 6, 2009
Filed:
Apr 18, 2007
Appl. No.:
11/736748
Inventors:
Vyacheslav I Slavin - Berlin, DE
Yury Budansky - Oakland NJ, US
Leonid Levitan - Brooklyn NY, US
Walter Breidenstein - Boyne Falls MI, US
Assignee:
Sorowell Production Services LLC - Walloon Lake MI
International Classification:
E21B 49/00
G01V 3/00
US Classification:
7315211, 324376
Abstract:
A method and apparatus for determining petrophysical parameters within a geologic formation pressurizes a geologic sample through a set of predetermined effective pressures, energizes the sample at each predetermined effective pressure with an electric current and/or sonic energy, and measures a conductivity value (electrical conductivity and/or sonic velocity). Permeability and/or porosity are also measured at each pressure through a traditional method and the functions are compared so that permeability and/or porosity can be subsequently derived from a sonic or electrical measurement of a comparable sample under a effective pressure. An apparatus is also described for acquiring the measurements under tri-axial compression, with a computerized interface in one embodiment.

Method And Apparatus For Withdrawal Of Liquid Phase From Wellbores

View page
US Patent:
60590408, May 9, 2000
Filed:
Sep 19, 1997
Appl. No.:
8/933628
Inventors:
Leonid L. Levitan - Brooklyn NY
Vasily V. Salygin - New York NY
Vladimir D. Yurchenko - Brooklyn NY
International Classification:
E21B 4300
US Classification:
166372
Abstract:
A method is for increasing the production of a hydrocarbon wellbore at its medium and last stage of exploitation, based on removal of the accumulated liquid phase from the bottom of the well. The method includes the installation of a device within the well. The device includes a mandrel and sealing assembly, with the nozzle installed inside the mandrel and above the sealing assembly. Apertures are drilled through the mandrel and the nozzle throat. The device creates the low pressure zone in the tubing of the well and evacuates the liquid phase from the tubing wall and the bottomhole to the gas-liquid upwardly directed flow core.
