    Abstract: Described is a method including emplacing a breaker fluid into a wellbore drilled with an oil-based drilling fluid that forms an oil-based filter cake. The breaker fluid includes a non-oleaginous base fluid and a surfactant blend comprising an alkyl polyglycoside, an ethoxylated alcohol, and a triethyleneglycol monobutyl ether. The method further includes allowing the breaker fluid to break the oil-based filter cake.

    Abstract: A screen assembly includes a frame having an outer perimeter and at least one inner support member, and at least one smooth surface affixed to the frame, where the smooth surface(s) have perforations. The frame may include a plurality of contact points extending upward from a top surface, and at least one smooth perforated screening surface is affixed to the plurality of contact points on the frame. In some cases the smooth surface comprises a perforated region and an erosion resistant region. Also, the perforations may have a shape that includes one or more corners. The smooth surface may be a perforated metal foil, sheet metal, and the like. Perforations may be apertures having one or more opening area sizes across the span of the screen assembly.

    Abstract: This disclosure is generally drawn to systems, devices, apparatuses, and/or methods, related to monitoring a shaker and monitoring a room in which shaker(s) operate. Specifically, the disclosed systems, devices, apparatuses, and/or methods relate to controlling an actuated arm to inspect, remove, replace, repair, clean the shaker and/or screen assemblies based on monitoring the shaker and its screen assemblies, and to adjust or maintain shaker(s) in a defined area such as the room in which shaker(s) operate. While the examples disclosed herein generally describe shakers for separating solids from fluids, the present disclosure contemplates that other separation equipment (e.g., machines for separating solids from other solids) may also be monitored and controlled by the systems and methods described herein.
