Closed Mud System

Definition - What does Closed Mud System mean?

A Closed Mud System is a control system whereby the mud generated during drilling activities constantly keeps rotating in the system and the things discarded as waste materials are drilled up rock materials and moisture. It is a type of mud system specially designed for oil gas drilling activities. It is also known as oil drilling mud system. It includes the solids control equipment such as shale shaker, decanter, desilter and desander. It may also include mud tanks as per the requirements.

Petropedia explains Closed Mud System

There are two types of Mud systems used at the drilling sites, i.e., closed mud system and not closed loop mud system also known as reserve pit. In a closed mud system, the mud, solid rocks and other ingredients generated from the drilling activities constantly circulate through a closed mud system in which mud is processed by mechanical processes such as screening, hydro-cloning and centrifuging. Through this process, the mud gets separated from the solids and the remaining mud passes through the wastewater cleanup techniques in order to remove the colloidal solids.

An ideal Mud System consists of the following components:

  • Mud cleaner
  • Mud gas separator
  • Desilter
  • Desander
  • Degasser
  • Mud pumps
  • Mud agitator
  • Sand Trap
  • Centrifugal pumps
  • Mud Tanks
