Appl. No.:

11/352889

Inventors:

Kevin W. Smith - Houston TX, US
Robert L. Sloan - Katy TX, US

Assignee:

Total Separation Solutions, LLC - Houston TX

International Classification:

E21B 43/40
E21B 21/06
B01D 17/02
B01D 17/04

US Classification:

16625001, 166267, 175 40, 175 66, 210708, 210737, 210748

Abstract:

A cavitation device is used to heat, concentrate and recycle or otherwise reuse dilute and other oil well fluids, brines and muds, and solution mining fluids, all of which commonly contain ingredients worthy of conservation. The cavitation device is powered by a Diesel engine whose exhaust may be used to heat the incoming fluid, and the product of the cavitation device is directed to a flash tank.

Appl. No.:

11/080838

Inventors:

Robert L. Sloan - Katy TX, US

Assignee:

Total Separation Solutions, LLC - Houston TX

International Classification:

E21B 47/00

US Classification:

1662525, 175 66

Abstract:

Circulating completion and workover fluids used in hydrocarbon recovery are filtered after monitoring for viscosity, which frequently causes plugging of filters. A viscometer generates a signal representative of viscosity in the fluid; the signal is used by a programmable controller to divert viscous fluid from the filter, or to take other action to prevent damage to the filter. The viscometer can be used in various positions in the system.

Appl. No.:

11/703950

Inventors:

Kevin W. Smith - Houston TX, US
Robert L. Sloan - Katy TX, US

Assignee:

Total Separation Solutions, LLC - Houston TX

International Classification:

E21B 43/40

US Classification:

166267, 166302, 175 66, 210737, 210738, 210747

Abstract:

Cesium solutions are treated in a cavitation device to increase their temperature and facilitate the removal of water from them. The context is normally an oil well fluid or a mining solution. The concentrated solutions can be reused, in the case of oil well fluids, or more easily handled for recovery of the elemental cesium or cesium in the form of a salt. Thermal energy is saved by using the concentrate or the water vapor to heat various streams within the system.

Appl. No.:

11/702857

Inventors:

Kevin W. Smith - Houston TX, US
Robert L. Sloan - Katy TX, US

Assignee:

Total Separation Solutions, LLC - Houston TX

International Classification:

B01D 17/04

US Classification:

210708, 166267, 175 66, 210712, 210718, 210737, 210738, 21074801, 210774

Abstract:

A cavitation device is used to heat and facilitation the separation of mixtures and emulsions of oil and water. Waste heat from the power source for the cavitation device may be utilized to elevate the temperature of incoming mixtures or emulsions. The heated mixture of emulsion is sent to a separation vessel where vapor may be removed and/or recovered, and where oil is removed as it separates into an identifiable layer. The separation vessel may be a flash tank.

Assignee:

Total Separation Solutions, LLC - Houston TX

International Classification:

E21B 21/06
B01D 1/00

US Classification:

210739, 210742, 21074802, 210805, 175 66, 1662525, 159 473

Abstract:

Circulating completion, workover and drilling fluids used in hydrocarbon recovery are filtered after monitoring for viscosity, which frequently causes plugging of filters. A viscometer generates a signal representative of viscosity in the fluid; the signal is used by a programmable controller to divert viscous fluid from the filter, or to take other action to prevent damage to the filter. The viscometer can be used in various positions in the system. Fluids deemed too viscous for the filter can be sent to a viscosity-reducing device, which may be a heating, shear-thinning, or cavitation device, to reduce its viscosity, enabling the fluid to pass through a filter without fouling. After filtering and a return to a lower temperature, the fluid may be treated if necessary to become viscous again for a useful purpose.

Appl. No.:

11/705300

Inventors:

Kevin Smith - Houston TX, US
Robert Sloan - Katy TX, US
Harry Smith - Montgomery TX, US

International Classification:

E21B 47/00

US Classification:

166250010

Abstract:

A cavitation device is used to reduce the water content of used or wastep solutions and slurries, including oil well fluids and muds, solution mining fluids, industrial oil/water emulsions, and other used or wastep aqueous industrial fluids. A main reason for reducing the water content of such fluids is to facilitate their disposal or reuse. Thermal energy from the steam and vapor produced by the non-scaling cavitation device is recycled in steam turbines or piston expander engines, or otherwise facilitates evaporation through a membrane or condensation to useful fresh water; the efficiency of the process can be enhanced by mechanical vapor recompression.

Appl. No.:

11/906463

Inventors:

Kevin Smith - Houston TX, US
Robert Sloan - Katy TX, US
Harry Smith - Montgomery TX, US

International Classification:

B01D 39/00
B01D 43/00

US Classification:

210806000, 210486000, 210808000

Abstract:

A screen for separating solids and liquids is formed from parallel strips of wedge wire or similar material into a two-sided enclosure having the flat bases of the wedge wires oriented to contact dirty liquid. Unfiltered liquid containing solids contacts the screen surface on both sides of the enclosure, forming a passage for filtrate. A wedge wire screen may be bent back on itself to form a C-shape or may be a closed curve, still exposing only the flat sides of the wedge wires to the dirty liquid, and collection filtrate within the enclosure so formed. Filter units may be placed in a housing adapted to accommodate two or more in a substantially concentric relationship.
