  • Method for settling suspended fine inorganic solid particles from hydrocarbon slurry and additive for use therewith
    Patent number: 7223331
    Abstract: Disclosed is a method for settling suspended finely divided inorganic solid particles from a hydrocarbon slurry using an additive. The additive comprises (a) a hydroxy-terminated polyoxyalkylate chain(s) containing polymer having at least one oxygen atom and at least one nitrogen atom and, optionally, (b) other components such as a solvent, an acid or mixtures thereof.
    Type: Grant
    Filed: June 6, 2003
    Date of Patent: May 29, 2007
    Assignee: Baker Hughes Incorporated
    Inventors: Joseph L. Stark, Robert S. Lauer, Lawrence N. Kremer

  • Method for separating solids from hydrocarbon slurries
    Patent number: 6316685
    Abstract: Disclosed is a method for separating finely divided solids from a hydrocarbon slurry by using an additive that comprises a polymer and, optionally, an alkylbenzene sulfonic acid; and a composition of the additive thereof. The polymer is a polymer having (a) a polymeric backbone comprising polyol units and at least one unsaturated polycarboxylic unit, (b) acrylate units coordinated via unsaturated polycarboxylic units, and (c) oxyalkylated alkyl phenol units.

  • Process to enhance removal of adhering solids from the surface of wellbores and sand control devices therein
    Patent number: 5783526
    Abstract: The invention provides: (1) a process to enhance the removal of solids such as clays, clay-like solids, and shale solids-drill solids-from the surface of a borehole, the solids being deposited from well drilling, completion, or workover fluids during well servicing operations; and (2) a process to enhance the removal of such solids from screens or other sand control devices present in a borehole. The process comprises contacting the solids with an acidic soak solution containing a polyglycol or mono ether derivative thereof and thereafter contacting the surface of the borehole with a wash solution to remove the solids from the borehole.
