Abstract: A system for separating components from a slurry of drilling fluid and drill cuttings on a shaker screen having an upper side and a lower side within a shaker. The system also has a pressure differential generator to pull an effective volume of air through a section of the shaker screen to enhance the flow of drilling fluid through the section of the shaker screen and the separation of drilling fluid from drill cuttings and further maintain an effective flow of drill cuttings off the shaker. A method of separating components of a slurry of drilling fluids and solids has the steps of delivering the slurry to a shaker, flowing the slurry over a first screen and applying an effective amount of vacuum to a first portion of the first screen to remove the drilling fluids from the slurry without stalling the solids on the first screen.

Abstract: The present disclosure relates to methods of controlling a microbial level in an aqueous fluid or a solid component used in an oilfield operation or a pre- or post-production process associated with wellbore production, the method comprising: measuring a microbial parameter of the aqueous fluid; and subsequently using the measured microbial parameter to decide on an appropriate antimicrobial treatment. These proposals also relate to methods further including monitoring of a microbial parameter in such a fluid or on such a solid component over a period of time. The methods and aspects of the present disclosure may be applied in any oilfield operation or a pre- or post-production process associated with wellbore production.

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 for measuring particle size distribution in a fluid material, involving inserting a laser beam instrument directly in the fluid flow line, wherein the laser beam instrument focuses a laser beam on a window directly coupled with the fluid flow line, wherein the fluid flow line comprises a fluid having a plurality of particles of different sizes, measuring a diameter of at least one particle in the fluid flow line by reflectance of the at least one particle as the at least one particle passes through the focused laser beam, and determining a duration of reflection of the at least one particle, and obtaining a count of particles in each of a pre-set range group of particle sizes, wherein the count of particles is used to determine particle size distribution in the fluid flow line.
