The basic function of the Shale Shaker is to provide primary solids removal from both oil based mud (OBM) and water based mud (WBM) during drilling operations.
Dual deck shaker is one of type shale shakers. As we know, it has two decks: the top deck use coarse screen and the bottom deck use fine screen. The biggest benefit of use dual deck shale shaker is reduced the number of shakers required on solids control system and can deliver high processing capacities.
The performance of an oilfield shale shaker
Shale shakers process drilling fluid and remove most of the large particles. The efficiency of operation of other solids separation equipment depends heavily on the proper and effective functioning of the shale shaker. Dual deck shakers are had tremendous advantage on the field of generate dryer cuttings and decease none-productive time (NPT).
The Screens of dual deck shale shaker
Selection of screen mesh for a particular application depends on a number of factors: flow rate, fluid condition, formation, rate of penetration (ROP), fluid type and number of shakers. The finest screen possible is to be used to ensure optimum performance to the relative screen life. However, coarser screens give higher capacity.
The screen cloth is considered to be one of the most important parts of a shale shaker and hence a good understanding of screen technology and its effects on shaker capacity are important.
Dual deck shale shaker use two differnet mesh screen. The top deck use coarse screen bring about scalping screen function.
The bottom deck of shale shaker use fine screen to eliminate solids from drilling mud.
