GN Solids Control is one of the leading manufacturer who are specialized in both oil & gas drilling rig, as well as compact mud system for HDD, CBM drilling. 500GPM mud recycling system for HDD and CBM is one of the most common model from GN Solids Control.

CPP(China Petroleum Pipeline Bureau),the largest HDD contractor in China, by now, they have already got nearly 30 sets mud system from GN Solids Control. Before they shift to GN, they bought mud system from U.S. And many user contact GN for mud system as they see GN 500GPM mud system running world wide with CPP worldwide activities.

GN 500GPM HDD mud recycling system

GN 500GPM mud system for HDD is a high configration including all the 4 phase solids control equipment. For higher standard, it includes 2 tanks to insure sufficient space to store the active mud. For some users wants system more compact, GN offer 1 tank system with all 4 phase treatment equipment on it.

Solids Control equipment included in GN500GPM HDD mud system under High ranking:

1) One unit 500GPM linear motion shale shaker is proved by both home and abroad customers as a well performed unit.

2) Mud Cleaner is designed 2 units De-sander cyclones and 12 units De-silter cyclones to meet a maximum 1000GPM capacity is case damage of any cyclone leading to broken down.

3) One uint GNLW363G decanter centrifuge  separate ultra fine solids in drilling mud greatly enhance the quality of mud. (Centrifuge is for option)

GNLW363 decanter centrifuge is the perfect model for LGS and HGS separation. It can be used for difference application while running under suitale speed.

GNLW363 LGS and HGS decanter centrifuge parameters as below:

Bowl diameter: 360mm (14 inch)

Bowl length: 1270mm (50 inch)

Max capacity: 200GPM

Bowl speed: reach up to 3900 rpm

G force reach up to 3063.

While matched with PLC control panel, it can adjust low speed for HGS, or high speed for LGS.LGS and HGS centrifuge for sale

Why choose GN brand centrifuge for LGS and HGS:

1) Equal to Derrick DE-1000 and Swaco 518 centrifuge, but highly cost effective on price

2) Fixed speed and VFD centrifuge for option

3) Centrifuge material Stainless steel 316 L

4) Centrifuge screw protection: tungsten alloy tile, or coated with ceramics as optionMiddle East centrifuge for sale

Besides treatment of LGS and HGS, GNlw363 centrifuge are suitable for a wide range of pplications:

1) Matched with Dewatering unit for dewatering

2) Used with oil and gas drilling rig mud system for barite recovery, operating under lower speed

3) Used with oil and gas drilling rig mud system for fine solids separation, operating under lower speed

4) For waste management and working together with vertical cuttings dryer or high G shaker

Shale shaker is the act as the first stage solids control equipment. Its performance important to the whole system. If the shale shaker can work well, it can greatly improve the lifetime of next stage equipment.

Shale shaker vibration

Vibration of the shaker basket creates G-forces which help drive shear thinning fluids such as drilling mud through the screens. Vibration also conveys solids off the screens. Most linear motion shakers operate in the range of 3 to 4 G’s to balance throughput with screen life. G-force is a function of vibration frequency (rpm) and stroke length.

Top brand Linear motion shale shaker

Top brand Linear motion shale shaker

But there are alway some misunderstanding on shale shaker performance, it should be avoided :

• “High-Speed” should not be equated with “high performance”.

Laboratory tests indicate that, in the normal operating range for linear motion shale shakers, lower frequency vibration and longer stroke lengths improve throughput capacity. Most linear motion shakers operate at 1200 to 1800 rpm.

• Avoid deck inclinations above 3˚.

High deck angles reduce solids conveyance and increase the risk of grinding soft or friable solids through the screens.

• Shakers are designed to accept either hookstrip or rigid frame screen panels.

Hookstrip screen panels are the most common and are usually cheaper, although cuttings wetness can be a concern due to deck curvature. Flat, rigid frame panels promote even fluid coverage, but can cost more.

• Shakers may have single or tandem screening decks. Single deck shakers offer mechanical simplicity and full access to the screening surface. Single deck shakers may be arranged to process mud sequentially as a “cascading” system to improve performance under high solids loading conditions. Tandem deck shakers offer improved processing capacity under high solids loading conditions when space is limited.

About microtunneling

Microtunnelling is a nature method of construction using pipe jacking. In many countries and areas, it also defined as a “Trenchless Construction Method”.

Slurry separation system for microtunneling

Microtunnelling project usually takes in urban district. In this case mud system matched for microtunneling request compact and a very small footprint recirculation slurry system with different capacity. This kind of mud system usually called as “slurry separation system”.

TBM Slurry Separation System In Oman

Features of slurry separation system

1) Steel Frame Screen with large open microns usually used.

As the solids usually bigger than oil and gas drilling, solids content higher and many bigger size sands / solids. And it is big diameter well with smaller depth, no higher request for mud quality. It is no need to separate very fine. And steel frame have a longer lifetime for microtunneling.

2) Compact system with smaller footprint: all separation equipment combined together, a storage tank and a mixing tank.

Usually, GN only offer separation plant and equipment for mixing part. And recommend users to build storage / mixing tank locally to save cost.

3) Big size hydro cyclones for large capacity. And it is not easy to be blocked.

GN Solids Control have exported 9 mud system to Australia from last year, for coal bed methane drilling and HDD (horizontal directional drilling).  The feedback is very exciting. More and more Australian companies are going to buy from us. And we are going to attend the No-dig exhibition in October, 2011.

Coal Bed Methane Drilling Exploration in AustraliaCBM drilling mud system

Although the presence of methane has been known ever since coal mining began, separate commercial production of CBM is a relatively recent step. This commenced in the USA in the 1970’s, and exploration for CBM in Australia began in 1976 in Queensland’s Bowen Basin when Houston Oil and Minerals of Australia Incorporated drilled two unsuccessful wells. In February 1996 the first commercial CMM operation commenced at the Moura mine in Queensland methane drainage project (then owned by BHP Mitsui Coal Pty Ltd). In the same year at the Appin and Tower underground mines (then owned by BHP Pty Ltd) a CMM operation was used to fuel on-site generator sets (gas fired power stations). The first stand alone commercial production of CBM in Australia commenced in December 1996 at the Dawson Valley project (then owned by Conoco), adjoining the Moura coal mine.

Coal Bed Methane Drilling Mud System

Very similar to systems for HDD, but higher required about the electricity. Now we are learning very well about this part, that is why we are competitive, our manager usually says. Very Thankful for the clients which are patient, and help us to know all these very well.

Here is a list of some exciting news, if you want to know more, kindly contact us.
