Desanders and desilters (Figure 1) are secondary solids control equipment used in oil and gas drilling rigs (check also: types of drilling rigs) that use

When the mud is static, the rheological properties should prevent solids (weighting material and drilled formation solids) from settling. The relevant property in this respect
Most formation solids can be removed by mechanical means at the surface as shale shaker screens. Small particles are more difficult to remove and have
The shale shakers are the first mechanical treatment of the returning drilling fluid for solids control.None of the other mechanical devices can cope with solids
Shale Shaker performance Design is a function of: Vibration Pattern Vibration dynamics Deck size and configuration Shaker screen characteristics Mud rheology (plastic viscosity) Solids loading
The principal factors governing the selection of type (or types) of drilling fluids (mud) to be used on a particular well are: The characteristics and
Various properties of the drilling fluids are measured as an indication of the performance of the mud in the hole. Methods for measurement of these
Drilling muds are designed to facilitate drilling operations and provide proper cuttings transport. They are not necessarily conducive to efficient mud displacement, logging, or completion
Yield Point in drilling mud is defined as the measure of the fluid’s initial flow resistance or the calculation of a value required to move
OBM oil-based mud requires special chemicals additives to ensure that the emulsion is extremely stable and can withstand conditions of high temperature and contaminants. Oil
