Abstract: A kinetic gas hydrate inhibitor is provided as a polyester polymer with a plurality of amino or ammonium groups pendent directly from the backbone. A composition containing concentrated kinetic inhibitor is injected into gas wells, or into other systems involving transporting liquid gas mixtures through a conduit. Use of the kinetic inhibitor prevents formation of gas hydrates under conditions of temperature and pressure where they would otherwise occur.

Abstract: A method of cleaning a wellbore prior to the production of oil or gas, wherein the wellbore has been drilled with an invert emulsion drilling mud that forms an invert emulsion filter cake is disclosed. The method may include circulating a breaker fluid into the wellbore, where the breaker fluid includes a non-oleaginous internal phase and an oleaginous external phase, where the non-oleaginous phase includes a water soluble polar organic solvent, a hydrolysable ester of a carboxylic acid, and a weighting agent, and the oleaginous external phase includes an oleaginous fluid and an emulsifier, and where the hydrolysable ester is selected so that upon hydrolysis an organic acid is released and the invert emulsion of the filter cake breaks.

Abstract: Methods and apparatus for separating solid particles from a fluid. One preferred embodiment includes a tank for settling particles out of the fluid, a conical chamber at the bottom of the tank, an outlet connected to conical chamber, and a conical auger within the conical chamber. The tank may have a tangential inlet that creates a fluid circulation that exerts a centrifugal force on the solid particles to increase the settling of particles out of the fluid. The tank may have a static spiral on the inner wall that helps small particles coalesce into larger particles that settle faster out of the fluid. The fluid content of the solids removed from the tank may be controlled by varying the rotational speed of the conical auger. The rotational speed of the conical auger may be varied depending on the torque required to rotate the conical auger.
