    Abstract: A technique to facilitate removal of various types of particulates from fluids during well operations. The technique may employ a skid positioned at a surface location. A filtration system is mounted on the skid to enable filtration of particulates as the subject fluid flows from a system inlet to a system outlet. The filtration system comprises a bank of filtering stages arranged generally horizontally on the skid. For example, a first stage may be constructed with a generally horizontal vessel containing a first filter arranged to filter particulates from the fluid. The first stage also may comprise a magnet positioned to retain ferrous debris. Additionally, a second stage receives fluid exiting from the first stage and contains a second filter for further filtering of particulates from the fluid.

    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: A method of cleaning a wellbore prior to the production of oil or gas is disclosed, wherein the wellbore has been drilled with an invert emulsion drilling mud that forms an invert emulsion filter cake. The method may include the steps of circulating a breaker fluid into the wellbore, where the breaker fluid includes an aqueous fluid, a water soluble polar organic solvent, a hydrolysable ester of a carboxylic acid, and a weighting age, 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.
