| 20080196890 | MAGNETIC POWER TRANSMISSION DEVICES FOR OILFIELD APPLICATIONS - A method and apparatus relates to incorporating a magnetic coupling for use in oilfield applications. The magnetic coupling is operatively coupled to an oilfield machine to provide a controlled operational speed. The magnetic coupling may be operatively connected to a motor and a drive shaft where a speed of rotation of the drive shaft is controlled by an operation of the magnetic coupling. The drive shaft is operatively connected to the oilfield machine. | 08-21-2008 |
| 20090139770 | Cuttings treatment and reuse - A method for treating drill cuttings including depositing drill cuttings in a desalinization cell, the desalinization cell having a high end, a low end, and a cuttings pad. The method further includes washing the drill cuttings in the desalinization cell with a liquid phase and removing a cuttings runoff from the drill cuttings. Also, a method for treating drill cuttings including depositing drill cuttings in a desalinator, the desalinator having a geometric structure having a perforated side. The method further includes adding a liquid phase to the desalinator through the perforated side, washing the drill cuttings in the desalinator with the liquid phase, and producing desalinated drill cuttings and a cuttings runoff. | 06-04-2009 |
| 20100116753 | DEWATERING SYSTEM - A system for processing drilling mud, the system including a primary separation tank having an inlet for receiving drilling waste and an outlet in fluid communication with a feed line, and an injection pump in fluid communication with a polymer tank and the feed line. The system also includes a clarifying tank in fluid communication with the feed line and a first collection tank, wherein effluent from the clarifying tank is discharged into the first collection tank, and a centrifuge in fluid communication with the clarifying tank and a second collection tank, wherein effluent from the centrifuge is discharged into the second collection tank. | 05-13-2010 |
| 20100170859 | SAND SCREW DRYER - An apparatus and process for separating drilling fluid from drill cuttings are disclosed. The separations are performed in a drying auger unit, including: an inclined housing having side walls joined by a bottom and having an inlet end and an outlet end; at least one inlet for feeding a cuttings slurry to the inlet end; a helical auger located in the housing for transporting drill cuttings from the inlet end of the housing to the outlet end of the housing, and a drive for rotating the auger, an elevated pan disposed in and extending the length of the housing and having an arcuate cross section with a radius greater than a radius of the helical auger, wherein the pan is disposed proximate at least a lower quadrant of the helical auger; the housing further comprising a liquid recovery zone adjacent to the pan for transporting drilling fluids, separated from the drill cuttings during transport along the pan by the helical auger, to a liquid collection zone disposed adjacent to the inlet; an outlet for recovering drilling fluids from the liquid collection zone; and at least one fluid inlet nozzle for injecting a fluid into the liquid recovery zone to facilitate transport of any solids in the liquid recovery zone to the liquid collection zone; and at least one outlet for recovering drill cuttings having a reduced content of drilling fluids. | 07-08-2010 |
| 20100243576 | DEWATERING SYSTEM - Systems and methods for dewatering drilling fluid including a feeder, an aging tank, a polyductor configured between the feeder and the aging tank and a flocculant solution pump fluidly connected to the aging tank. Further, the system includes a portable skid to house the feeder, the aging tank, the polyductor, and the flocculant solution pump. In certain embodiments, the polyductor is configured to mix a liquid with a dry flocculant from the feeder, and disperse a resultant flocculant solution in the aging tank, the aging tank is configured to receive the flocculant solution, and the flocculant solution pump is configured to remove the flocculant solution from the aging tank. | 09-30-2010 |
