GN designed and produced oil drilling solids control system and drilling mud recycling system have been operated in the rig sites of 60 countries in the world, including Cuba. Estimates of total oil reserves in Cuba are varied, and depend mainly on estimations of undiscovered offshore deposits in the North Cuba Basin. Fearing an oil spill in Cuban waters, U.S. officials have forged a bond with the Castro regime to preserve the threatened marine ecosystem that connects the island nation to the Florida coast.

Below photos showed the workover rig solids control system used in Cuba: It including one set of XJ450 workover rig solids control system and one set of XJ650 workover rig mud recycling system. The main configurations are as below:

XJ450 workover rig solids control system:

2 units of mud tanks with mud agitators, mud guns, hoppers

1 set of mud gas separator

1 unit of water tank

1 unit of waste collection box

XJ650 workover rig mud recycling system:

2 units of mud tanks with mud agitators, mud guns, hoppers and shale shaker GNZS703E-HB

1 unit of diesel tank

1 unit of water tank

1 unit of fuel tank

1 unit of waste collection box

1 set of mud gas separator

The main features of these mud tanks are not traditional Rectangle tank, but V-bottom tank for easy cleaning of solids. Except for such design, we can also provide customized design tank like round bottom tank for easy cleaning, trailer/wheel mounted mud tank for easy transportation, and 3-runner oilfield standard design mud tanks. The mud tanks qty and total system volume can be also customized. If only the end-user have such special requirement, we will try our best to provide the best solution for your rigsite.

Pls contact either GN solids control or GN solids America for a customized proposal.

Mud cleaner is a combination of shale shaker, desander, desilter for oilfield drilling mud system, NOV Brandt also called it mud conditioner. There are many suppliers for mud cleaners, Derrick, MI-SWACO, Brandt, GN Solids Control, here we will make a comparison of the 4 model of mud cleaners. Take 1000gpm unit for example:

mud cleaner

GN mud cleaner

1 Derrick Mud Cleaner Features:

A round desilter manifold and/or a desander manifold is mounted in a cone discharge collection pan installed over the vibrating screen.Underflow from the hydrocyclones is received by the collection pan, which may feed directly to discharge or onto the vibrating screens for additional processing.

Derrick’s standard desander cone and desilter cone is 10” & 4”

2 MI-SWACO Mud Cleaner features:

Low profile through

Bypass intergral

Vertical installation method of desilter cone

MI-SWACO’s standard desander cone and desilter cone is 12” and 4”

3 Brandt Mud Cleaner

Patented pin-and-hole screen securing system

Brandt’s standard desander cone and desilter cone is 10” or 12” and 4”

4 GN Mud Cleaner

Small footprint, compact design; desilter cone is installed vertical but inclined, GN standard desander cone and desilter cone is also 10 inch and 4 inch, which is same with Derrick’s.

GN mud cleane is convenient to ship it by containers, GNZJ703-2S12N(1000gpm) footprint is only 2403x1883x2195mm, but same treating capacity, Brandt Cobra 16/2 Mud Conditioner dimension is 2692 mm x 2032 mm x 2565 mm. For same treating capacity and function equivalent, GN mud cleaner is with the smallest size.

GN solids control is one of the most professional drilling mud system manufacturer. GN offers a variety of drilling mud sytsem to fit your need in oil & gas drilling, water well drilling, horizontal directional drilling, geothermal well drilling, Coal bed methane, drilling waste management, etc. We can be your first line supplier for all of your drilling needs.

The working principle of most of drilling mud system is to separate large solids or cuttings to recycle the drilling mud. A common drilling mud system will include shale shaker, desander, mud cleaner, decanter centrifuge, mud agitator, centrifugal pump, mud gun, mud tank with accessories. Sometimes we will reduce some equipments according to the drilling mud condition.

Natural gas drilling rigs can be used not only to identify geologic reservoirs but also to create holes that allow the extraction of natural gas from those reservoirs. Primarily in onshore gas fields once a well has been drilled, the drilling rig will be moved off of the well and a service rig (a smaller rig) that is purpose-built for completions will be moved on to the well to get the well on line. This frees up the drilling rig to drill another hole and streamlines the operation as well as allowing for specialization of certain services, i.e., completions vs. drilling.

natural gas drilling mud system

natural gas drilling mud system

Natural gas is a naturally occurring gas mixture consisting primarily of methane, typically with 0–20% higher hydrocarbons. It is found associated with other hydrocarbon fuel, in coal beds, as methane clathrates, and is an important fuel source and a major feedstock for fertilizers.

Hydraulic fracturing, or fracking, uses huge volumes of water, chemicals and sand injected into rock at high pressure to release natural gas. Its development has unleashed a natural gas boom in the US and around the world. US has developed such method to drill for natural gas.

GN solids control provide mud cleaning system for directional drilling and fracking for natural gas, we are thinking to design such mud system for US market. All the electric motors and control panels will use IECex certified or US motors.

To design a system, we need to clarify the following questions:

1 What kind of drilling you are doing?

2 What is your required active capacity of the mud pits

3 What equipments you used before? If you have no experience, we will provide our standard design.

GN solids control design and manufacture a complete solids control system/drilling mud system for oil & gas drilling, now we need a mud cooling system in our design, to make it more user-friendly. Usually we call the mud cooling system as mud cooler.


Application of mud cooling system

Scomi Oiltools Mud Cooling System

Scomi Oiltools Mud Cooling System

  • Oil, Gas, Geothermal Drilling - cooling drilling fluids
  • Oil and Gas Refineries – gas cooling/condensing
  • Petro-Chemical – steam condensing
  • Power Generation – fluid cooling
  • Steel – waste water cooling

In Oil, Gas, Geothermal Drilling ,the Mud Cooling system is used to reduce the temperature of drilling fluid returned to the surface.


In HT / HP wells the temperature of the drilling fluid must be strictly controlled to keep it’s properties within the specified parameters for that particular well. If the temperature of the drilling fluid is allowed to increase then a variety of problems can occur such as high equivalent circulating density (ECD), formation breakdown, lost circulation, packing off, stuck pipe and evaporation of the oil and water phase.


Why use mud cooler?


1 crew safety

2 Reduction of mud temperature in return lines especially important in Oil based systems to be maintained below flash point.

3 reduction of mud temperature reduces the risk of fire, blowouts, and helps provide safer drilling operation/ environment.


Benefits to well, drilling fluids, downhole equipment

Mud rotary drilling is popular in wellbore drilling, offshore works, well drilling, Horizontal directly drilling, mining, geotechnical. Drilling fluid system is one very important part of the drilling work. The two main parts of the drilling fluid system is the actual drilling fluid and the solids control equipments, to separate the cuttings from the drilling mud at the surface, and circulating water based drilling fluid.

hdd drilling fluid system
As we all know the quality and charactor of the drilling fluid effects the drilling works. The viscosity, density, fluid loss control, sand content, gel strength, and so on. The drilling fluid system is used to control them.
If not use the drilling fluid system correctly, effiently, there must be some trouble. High fluid density causes pressure in the formation of the borehole. This pressure drives the drilling fluid through the filter cake into the formation, leads to excessive drilling fluid loss to the formation, and extends well development time required to remove the mud from the formation. As the fluid density increases, the pressure required to move the fluid up the borehole also increases, leading to high mud pump pressure requirements. Continue reading »
