Mud Solids Control Equipment

Last week we shipped another set of decanter centrifuge to South America. GN solids control is a new star for South America market, there are several sets of centrifuge working in site in Colombia. Our improved high speed centrifuge GLW360x1250 has been proved in good performance in solids liquid separation.

GN improved decanter centrifuge has the following features:

G-force 2035G, separation point 2~5μm, differential torque 4000N/m max, bowl speed( during working) 3200rpm, differential ratio 57:1.

Bowl

The bowl has a cylindrical/conical shape and rotates at a pre-set speed optimal for the application. The slurry rotates with a different scroll design or by modifying an existing scroll. Scroll pitch and single or multiple flight configurations are important design variables.

Scroll

The scroll rotates at a slightly different speed than the bowl and conveys the deposited solids toward the conical end of the bowl.

Materials of construction

GN solids control uses high-quality stainless steel for all wetted areas. Bowl and scroll castings are made from centrifugal cast high strength and corrosion resistant stainless steel.

Coal Bed Methane (CBM) is natural gas contained primarily (about 90% -100%) of methane (CH4) found in coal seams. Methane is also the major component in petroleum natural gas (about 70% – 90%) that is widely used today. CBM is generated from the microbiological process or thermal process in the coal seam and recognized as one of the cleanest fossil fuels. Indonesia has one of the largest CBM reserves in the world with a potential 453 trillion cubic feet (“Tcf”), more than double the country’s natural gas reserves. The South Sumatra Basin, the largest CBM basin in Indonesia, is estimated to contain in-place resources of approximately 183 Tcf; and the Kutai Basin, the third largest CBM basin in Indonesia, is estimated to contain in-place resources of approximately 80 Tcf (SPE, 2004).

GN has exported many sets of mud tank system to Indonesia for CBM project. The technique to exploit CBM is different with that applied to the fossil natural gas, while both share the common in terms of marketing and utilization. Simply, CBM is exploited by drilling shallow wells into coal seams, dewatering the seams, extracting the methane from the seams and finally compressing the methane.

When design the CBM mud tank system, you should consider the following points:

1 shale shaker inlet method, usually the CBM well is lower than oil drilling well, maybe they will not use overhead manifold, but they have a mud pit and a submersible slurry pump to shale shaker.

2 fine particles, CBM drilling may contain much fine particles, most of clients will use high speed centrifuge.

3 Mud tank height, it should be a little lower than oil well drilling mud tank system.

Producing oil and natural gas wells occasionally requires major repairs or modifications, called “workovers.” Workover services are carried out with the same type of rig used to perform maintenance services, although the rig often is outfitted with specialized equipment including rotary drilling equipment, mud pumps, mud tanks and blowout preventers. A workover may last anywhere from a few days to several weeks to accomplish.

Many oil wells rely on artificial lift methods to make the oil surface. Oil can be lifted by different techniques , which require specialized equipment operating under dificult conditions for long periods of times. These equipments are assigned to the wells as long as their use is economically rentable. Failures of these equipments over the time require maintenance services such as cleaning, reinstatement, stimulation and others, which are essential to the exploitation of the wells. These services are performed by workover rigs.

GN solids control provides related solids control equipments and consultant service for workover rig operation. The most common workover model clients may require is XJ550HP, 450HP, 350HP, 650HP. GN solids control owns standard design of solids control equipments for these workover rig models.

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.

Chile has the world’s largest copper reserves and is also the largest producer and exporter of the metal. In 2011, Chile expects global copper output will reach 16.5 million tonnes, an increase of 345,000 tonnes over 2010. Of the 16.5 million tonnes of output, Chile expects to supply 5.7 million, roughly one-third of the total demand.

Copper mining has played a significant role in the Chilean economy since at least 1825 when foreign investors were actively competing to control the country’s rich copper and silver deposits. By 1835, Chile was exporting 12,700 tonnes of copper per year, mostly to the United States. By 1860 copper accounted for fifty-five percent of the economy.

Mining rig drilling also needs mud recycling system, consider environment protection and drilling requirement. Since mining rig is usually very small, so the mud system should be portable and compact, the production cost will be lower than HDD and oil drilling.

Last week we exported a mud mixing plant to Spain. Every year we design and manufactured hundreds of mud mixing plant for international clients, especially for developed countries, like UK, Australia, USA, New Zealand, Singapore, etc.

The mud mixing plant is with mud hopper, slurry pump, mud agitator, mud tank, control system, and the painting color can be customized. The mud tank dimension is designed by the active capacity clients required. And we should consider the container shipment when design, freight charge is one of the factor clients may care.

Except for skid-mounted mud mixing plant, we can also make it portable mud mixing plant, and connected with truck head for convenient transportation.

During shipment, we put mud hopper inside the tank by remove the Galvanized Steel Grating, and put the hand rail, stairs on top of the tank.

Except for mud mixing plant, we can also produce mud recycling system plant, including shaker tank, suction tank, reserve tank, water tank, trip tank, pill tank and related solids control equipment. We can also add dewatering unit if clients required.

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.

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.
