If you have over 30 years experience for drilling, you will know, what is real required and what is not for close loop mud system. Sometimes people just seek for unrealistic specifications, which did not mean good for the operation. GN solids control would like to share your new idea about the drilling solids control, and put your idea into realization. We have the ability to design as your layout, no matter you choose us as the complete system manufacturer or not.
 close loop mud system Recently drilling has been changed a lot, the old experience did not work, people has their own new design. “Zero discharge mud systems” are urgently required because of the environment protection. Auger box, screw conveyor can be used to collect the drilling cuttings from shale shaker, desander, desilter, mud cleaner, dewatering unit and centrifuge, then transfer them to a catch pit for later processing. In some development company where the government did not have strict regulation on environment protection, they even do not use any mud system, and let the drilling fluids discharged directly. They may face big problem in the future.
Dewatering unit is required to work together with the system, it can make further process of the fluids after processed by centrifuge after the well is finished.
The mud tank is designed similar to 40 feet standard container, it is more convenient to transport in any countries in the world. All the lifting device, dimension, skid is same with container, and we put GN solids control equipments on top of it.
If you required Close Loop mud System for oil & gas drilling, pls contact GN solids control, our service including design, consultant, manufacture and shipment.

GN solids control exported several sets of drilling mud system to Amazon region, including Ecuador. We can produce the complete drilling mud separation system, including shale shaker, vacuum degasser, desander, desilter, decanter centrifuge, vertical cutting dryer, mud tank, etc.
Ecuador produces more oil than it needs for domestic consumption and thus it is one of the country’s leading exports. Therefore, any new drilling for oil is not intended to meet local demand but is intended for export overseas, most likely to Japan and the United States.
 drilling mud separation system Drilling mud is used to control subsurface pressures, lubricate the drill bit, stabilize the well bore, and carry the cuttings to the surface, among other functions. Mud is pumped from the surface through the hollow drill string, exits through nozzles in the drill bit, and returns to the surface through the annular space between the drill string and the walls of the hole.
Drilling mud separation system
As the drill bit grinds rocks into drill cuttings, these cuttings become entrained in the mud flow and are carried to the surface. In order to return the mud to the recirculating mud system and to make the solids easier to handle, the solids must be separated from the mud. The first step in separating the cuttings from the mud involves circulating the mixture of mud and cuttings over shale shakers.
The liquid mud passes through the screens and is recirculated back to the mud tanks from which mud is withdrawn for pumping downhole.

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.

Drilling mud is a important part for the drilling work to maintain the wellbore; Cool, lubricate and support the bit and drilling assembly  and 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. Other parts are also very important, centrifugal pump, mud agitator, mud gun.

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.
 
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 »

Solid control system, also referring as mud system, is used to separate the solids or gas from the drilling mud. There are several centrifugal mud separators such as hydro-cyclone separators (desander and desilter) and decanter centrifuge, and mud gas separator, which separate drilling mud and gas.
Hydrocyclone Separator
Hydrocyclone separator is always referring as desander and desitler, used after shale shaker in the solids control system. Usually the cone diameter is more than 6″is called Desander, and used as the second-control equipment in drilling operation. the cone diameter is less than 6″is called Desilter, and used as the third-control equipment in drilling operation. We commonly used 5 “and 4″ cone to separate solid-phase particle size 15-47μm in the drilling fluid.
Decanter Centrifuge
Decanter centrifuge are used to process unweighted and weighted, water-based and oil-based drilling fluids (muds). Mechanical energy is utilized to increase the gravitational force exerted on solids that are present in the mud system. Continue reading »
