HOW TO LAYOUT SOILDS CONTROL SYSTEM

elevated catwalk and PTC

Other than the drill floor itself, the solids control system requires more attention than any other single rig system whether onshore or offshore. For that reason, it is most important that the solids control system is designed to be as efficient and as maintenance free as possible. This section will discuss that pan of the mud system extending from the bell nipple (or diverter housing outlet) to the mud pump suction piping.

Mud Degassers

Introduce Degasser

Degassers are necessary to remove entrained gas bubbles from the mud. Gas-cut mud will impair the performance of centrifugal pumps. Since all solids removal equipment beyond the shakers requires a pump, the gas must be removed before it reaches these devices. If left unchecked and pumped downhole, the entrained gas will reduce mud density, which will, in turn, reduce the hydrostatic head in the wellbore.

Vacuum Degasser Benefit

Introduce vacuum degasser

The vacuum degasser, also known as a mud/gas separator is one of the first units of solids control equipment arranged to treat drilling mud. As such, they process all of the drilling mud from the flow line before the mud reaches the primary shale shakers. The vacuum degasser consists motor rated for continuous operating running an Ingersold-Rand vacuum pump with a push-button starter panel. The self-contained unit provides up to
Hg of vacuum to efficiently handle high-viscosity fluids.The units have no moving parts and rely on the density difference between the gas and the mud for removal. The process is simple, yet very effective for well drilling fluids processing system.
