See the photo on the right, it is a mud circulation system with mud gas separator, in oil drilling solids control system, the 1st phase cleaning equipments of mud circulation system is shale shaker, which is fed the mud from high pressure manifold, the mud gas separator is fed mud from the chock manifold. When much of harmful gas is found during drilling, they close the valve to stop feeding the shale shaker, and open the valve to feed to mud gas separator, and use hundreds of exhaust pipe to transfer the harmful gas from mud gas separator to a place far from well head, and use flare ignition device to burn it. Mud gas separator is not a part of solids control system, GN can manufacture both of them, so we put them together for your convenience.

Mud circulation system is also called mud cleaning system, mud recycling system, solids control system, Usually if a mud circulation system with mud gas separator, it is usually oil & gas drilling or geothermal, it can not be HDD or water well drilling. Mud gas separator is horizontally installed on the skid with the chock manifold on it together, it is easy for transportation.

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 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.

offshore drilling

offshore drilling

GN solids control produce mud recycling system/circulation system for both land rig(onshore drilling) and offshore drilling.

What is offshore drilling?

Offshore drilling is one of the greatest technological breakthroughs in recent decades, and many new techniques have been developed to profit from the abundance of oil underneath the ocean floor. While drilling for oil has been around for hundreds of years in one form or the another, the effective extraction of petroleum from beneath the sea floor did not surface until the last forty years. The search for oil often turns out to be unproductive, but this practice is vital for the economic future of many nations.

List of the top offshore drilling service companies

1 Transocean-the world’s largest offshore well services drilling company

Largest offshore driller with 165 mobile offshore drilling and production units, inland drilling barges and supporting assets.
– Largest “floating” rig driller with more than 60 semisubmersibles and drillships.
– Largest deepwater driller with almost 40 units that can drill in more than 2,000 feet of water.
– Largest shallow-water driller with 54 jackups, including the largest jackup fleet in the U.S. Gulf of Mexico with 27units.
– Largest inland drilling barge driller with more than 30 units.
– Largest offshore driller in market equity capitalization.

Last week GN solids control attend 11th CIPPE held in Beijing on 22th, March. To some extent, it is a successful oil show, Many professional manufacturers of drilling rig, drilling tools, drilling fluids solids control system/mud circulation system, and accessories, etc in China attend the fair.

 Although GN booth is not located in visible place of the exhibition center, we also have a lot of esteemed clients here.

 What is the features of GN mud circulation system?

1 It consists of GN new designed BEM shaker, GNZJ703 mud cleaner, LW450x1000N decanter centrifuge, mixing hopper and mixing pump, the complete electric control panel and tank accessories( stairs, handrails, slide walkways, mud pipeline, clean gate, etc)

 2 Process of GN mud circulation system

  First, drilling mud is flowed into the buffer box of the shale shaker through mud divided equipments, then entered the 2 sets of BEM shale shaker, after treated drilling mud flowed into shaker compartment, which is sand trap designed.

  #1 centrifugal pump feeds the mud from shaker compartment to desander cone of mud cleaner, then the clean mud droped into desander compartment;

  #2 centrifugal pump feeds the mud from desander compartment to desilter cone, then the clean mud droped into desilter compartment.

   The submersible slurry pump feeds the mud from desilter compartment to the centrifuge, to separate solids particle size 2~5μm. Now the clean mud can be used directly for drilling through pipelines, or weighten by mixing hopper. After weighten drilling fluids, they can be recycled and re-used in the drilling operations.

 3 Features of main equipments of mud circulation system

  3.1 GN BEM shaker features

1 adopts ANSYS limited element analysis

2 Adopt SS304 or Q345 high strength alloy material

3 Heat treatment on complete shaker deck

4 shaker surface is coated with heavy anticorrosive paint

Drilling mud is a important part for the drilling work to maintain the wellbore; Cool, lubricate and support the bit and drilling assembly mud circulating systemand so on, most important, remove cuttings from well. Then here it problem, to reuse the drilling mud. Then it is the time for mud circulating system to come here.

In some applications, the mud circulating system is equal to solids control system, but the full mud circulating system in drilling work, contains more. Except for the four phase, five equipments as we know, shale shaker, vacuum degasser, desander and desilter (or mud cleaner), decanter centrifuge. There also include mud pump, electric generator, control panel, chemical reagent treatment unit, and so on.

As you can see in the picture. It is used for the movable drilling rig, and also this system is movable. Usuall solids control equipments can not prevent the loss of the drilling mud. So we also must add chemic to the tanks to add fresh drilling fluids.mud circulating system Other parts are also very important, centrifugal pump, mud agitator, mud gun.

The main part in the picture: Continue reading »
