Abstract

The present disclosure relates to methods and apparatuses to separate solids from a drilling fluid. A shaker in accordance with the present disclosure includes a first screening deck having a first channel and a second channel, and also includes a second screening deck. Drilling fluid received by the first channel and separated through the first screening deck is directed to the second screening deck, and drilling fluid received by the second channel and separated through the first screening deck is directed to a sump of the shaker.

Description

technical field [0001] Embodiments disclosed herein relate generally to a vibrating screen for separating solids from a fluid. In particular, embodiments disclosed herein relate to a shale shaker having at least two screen decks, wherein the shale shaker can be used to allow drilling fluid to be processed both in series and in parallel. Background technique [0002] Oilfield drilling fluids, commonly referred to as "muds," are used in the industry for a variety of purposes. Among its many functions, drilling mud acts as a lubricant to cool the rotating drill bit and facilitate faster cutting rates. Typically, mud is mixed at the surface and pumped at high pressure downhole through the borehole of the drill string to the drill bit. Once the mud reaches the bit, it exits through various nozzles and ports where it lubricates and cools the bit. After exiting through the nozzles, the "spent" fluid returns to the surface through the annulus between the drill string and the dril...
