Rig Mud Pumps: Which is for onshore and offshore?

Updated: Nov 7, 2023

Drilling operations on rigs for oil and gas extraction are carried out either onshore or offshore. But what type of mud pumps are used for each?

Mud pumps circulate drilling mud (drilling fluid) throughout the system. They help to cool and lubricate the drill bit, carry the cuttings to the surface, and maintain the desired pressure at the bottom of the well. In other words, they facilitate the primary functions of the drilling mud: cooling, cleaning, and controlling the well

There are two main types of mud pumps used in drilling operations:

Triplex Pumps: These have three pistons and are currently the most common one. They offer a more steady flow of drilling mud compared to duplex pumps. They are more compact and can handle higher pressures, which is especially beneficial for deeper drilling and high-pressure environments. Their design reduces the pulsation in the mud flow.

Duplex Pumps: These have two pistons and are an older design compared to triplex pumps. Although they are less commonly used nowadays due to the efficiency and reduced pulsation offered by triplex pumps, they still find applications in some drilling operations.

In both offshore and onshore drilling:

Mud pumps must be robust enough to handle abrasive particles in the drilling mud, which can wear down equipment over time.

Pumps used in offshore operations are often subject to more stringent safety and environmental regulations due to the potential for oil spills and the challenging conditions of marine environments.

The choice of pump often depends on the depth and type of well, the drilling mud used, and the specific requirements of the drilling operation.

Other components that often accompany mud pumps include:

Power end and fluid end: The power end contains the components that convert the rotary motion of the drive to the reciprocating motion of the pistons. The fluid end is where the mud is drawn in and pushed out.

Pulse dampeners: These reduce the pulsation in the mud flow created by the reciprocating action of the pump.

Relief valves: These ensure that the system doesn't go above a certain pressure, providing an essential safety feature.

Charging pumps: These are smaller pumps that keep the mud pump charged with drilling mud.

The 2 types of mud pump, duplex and triplex are used in both rigs. We have the mud pumps and their spare parts, service and installation up to the rig. Get to know our product catalog.
