  • Patent number: 7373996
    Abstract: A method of separating drilling/production fluids from solid cuttings from a mixture received from down hole, without the use of shale shakers, de-sanders, or de-sanders, through the steps of flowing the mixture from the well bore into a flow line above the surface of a well; next, flowing the mixture into a single separation zone of a size capable of receiving the mixture directly from the flow line on a continuous basis; circulating or centrifuging the mixture to a desired RPM within the separation zone; providing a liquid permeable barrier surrounding the mixture as the mixture is centrifuged within the separation zone; collecting the liquid in a first retrieval zone after the liquid has penetrated permeable barrier; and collecting the solids that could not penetrate the permeable barrier in a second retrieval zone within the barrier.

  • Publication number: 20040256105
    Abstract: A system for heating drilling, completion, and/or stimulation fluids including acidizing liquids but not limited to; entering or exiting a wellbore, the system including a principal heat exchange vessel; a first inlet for introducing heat transfer media into fluid flow lines within the vessel; an outlet for flowing the heat transfer media from the vessel; a second inlet for introducing fluids returning from or returning to the well bore for receiving heat from the heating fluid within the fluid flow lines in the vessel; an outlet for flowing the heated downhole fluids from the vessel to be returned down the borehole; a heater for heating the heating fluid to a desired temperature before returning the heating fluid to the heat exchange vessel. Optimally, the drilling or completion fluid would be heated to 50° to 60° F. above ambient temperature.

  • Publication number: 20040139866
    Abstract: A method of treating and shaping drill cuttings for disposal, which includes the steps of providing initial separation of drilling fluid from the drill cuttings after the drilling fluid is returned from the borehole; drying the drill cuttings in a cuttings dryer; shaping the cuttings into pellets; granulating the cuttings pellets into granular material; and conveying the granulated cuttings for transport to an onboard bulk storage boat or to a dockside cuttings disposal site, so that the drill cuttings entering the cuttings dryer contain 20% to 40% or more of oil on cuttings (OOC) ratio of drilling fluids retained on the drill cuttings, while the cuttings are dried in the cuttings dryer have a moisture content of 1% to 8% total moisture. Next the cuttings are formed into highly compressed, spherical pellets, so that the pelletized cuttings can be transported more readily, and free of hydrocarbon cross-contamination during storage.
