Abstract: Methods include drilling at least one interval of a wellbore with a water-based wellbore fluid producing a filtercake in the at least one interval of the wellbore. The methods also include gravel packing an interval of a wellbore traversing a subterranean formation with a gravel pack that comprises polyhydroxycarboxylic acid, and hydrolyzing the polyhydroxycarboxylic acid to degrade at least a portion of the filtercake.

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: Described herein are splitters for holding and distributing input material to one or more decks of a gyratory sifter, where the splitter distributes approximately an equal amount of input material to each deck. An exemplary splitter may include a bottom surface, a sidewall, and one or more openings through the sidewall. Each opening may include a plurality of slits, allowing input material to pass therethrough. Where multiple openings are provided through the sidewall, the openings may be evenly spaced and have an equivalent area. The bottom surface may be substantially circular, and the sidewall may extend perpendicularly from the edges of the bottom surface. An exemplary splitter may be able to receive and distribute the input material when a gyratory force acts on the gyratory sifter on which the splitter is installed.

Abstract: A collection system for collecting materials, such as cuttings, drilling fluid, wellbore fluid, lost circulation material, hydrocarbons and mixtures thereof, from a vibratory separator in a collection trough and facilitating movement of the collected materials to a discharge conduit utilizing a squeegee member. The squeegee may be moved along a track between the discharge conduits to move the material in the collection trough to the discharge conduits. The squeegee may be moved pneumatically or hydraulically. The squeegee may also be moved along the track magnetically utilizing a magnetic piston train. Movement of the squeegee can be modulated based on the rate of material into the collection trough.
