Who need a cleaning system?
Any Directional Drilling contractor using boring machines with pumping capacities of 25 GPM or larger regardless of soil type or conditions. Contractors typically making bores larger than 6-1/2” Diameter and more than 200 feet long.
Contractors working in areas where mud disposal is expensive or restrictive.

Technical Benefits from GN Solids Cotrol (More than competitive price!)

Normally pumping higher volumes of fluid also provides an adequate presence of bentonite to repair filter cake as it is being scarred by rotating drill pipe. Keeping the filter cake in good shape will reduce chances of formation swelling while drilling in clay or shale thus reducing the chances of getting stuck.
Clean mud significantly reduces repair costs to mud pump, mud motor and circulation system components.

GN Solids Control have more experence to design a compact and lightweight system for your application.
Now GN have already developed some new products for HDD project, the MINI shaker is a highlight.

Does not require a full time dedicated operator. The unit is monitored for proper operation by the boring machine operator.

Unit Sizing of mud cleaning system
Unit sizing is influenced by two factors. First, the pumping capacity, in GPM, of the pump moving fluid and second, the type of cuttings being removed from the bore. If the cuttings are inert, such as sand or rock cuttings, the unit should be sized just a little larger than the pump capacity.
If a high cuttings volume is expected, such as with fast boring in soft formation, the next size larger unit may be considered. Follow operational tips as outlined in the “Tips and Tricks manual”, which is provided with each Mud Cleaning System.

Though some world famous motors like ABB, WEG, also have office in China, and Siemens also have invent in Siemens Beide, now we are going to introduce some local companies. Also no leeson, Cantoni group.

Nanyang Explosion Proof

Nanyang Explosion Protection Group Co. Ltd (hereafter indicated as CNE) locates in Nanyang city, Henan province, is one of the largest scientific research and production base of explosion-proof motors in China, the national export base for electro-mechanic products, and the national innovation enterprise as well as the chairman member of Ex motors branch of CEEIA.

Jiamusi Electric Machine Co., Ltd  

JEM as the biggest Special motor factory in China was founded in 1937 in Shenyang city. In 1950 it was moved to Jiamusi city. In 2008, the company has established the management concept for modern enterprise and carried out the reformation in all aspects, thus forming a new style stock company. He manufactured the first Ex motor, crane and metallurgical motor axial-flow local fans and canned motor in the history of China.

Other local brand like Hengli, Pinxin, is also very famous supplier.

And not only in USA, the shale drilling is becoming more and more popular. In the past week, China approved shale gas as an independent mining resource, a legal status that it hopes will encourage smaller Chinese energy firms to develop the unconventional energy source.

And in Poland, which holds the most active and best areas geologically for shale in Europe, where governments want to diversify their natural-gas supplies away from Russia, is another promising play.

As always, the technology used to extract oil and gas from shale rocks, a process that has revolutionized the U.S. energy industry, should be improved to protect the environment.
That is why we need tanks, solids control systems, and so on, if you are involved, contact GN.

It do not make too much sense if entangled to the definition point. What GN Solids Control can do for you:

1. Solids Control part

2. modelling of plant and site layouts

3. Mud tanks:  Drilling Fluid Storage Tanks; Mixing Tanks; Bulk Tanks;

4. High volume mud mixing and shearing systems

5. Operation and Maintenance Guide

6. Cutting dryer (coming soon), decanter centrifuge and so on.

The modular design enables tank battery configurations to fit narrow or spatially restrictive sites. Storage tank configurations include vertical interlocked groups of four or more for applications that require minimizing the ground footprint. Tanks can also be double stacked horizontally. And, both configurations can use the same modular manifold system.

Unlike conventional square-ended tanks, that require manual cleaning to remove settled materials, these mixing tanks have curved ends to improve agitation and minimize solids accumulation. Each mixing tank  also has two agitators and rotating mud guns.

Now GN Solids Control is tending to supply whole solution, not only what we produced, we solve your problem, so welcome to talk about this more….

For each kind of cones, need one separate tank compartment. Generally, a desander and a desilter manifold are available as part of the rig equipment. Hydrocyclones should process all drilling fluid entering their suction compartments independently of the drilling-fluid circulation rate.

The flowability requires the system operating continually. Suction is taken from the tank immediately upstream of the discharge tank. The number of cones in use should process at least 100% but preferably greater than 100% of the flow rate of all fluids entering the suction tank for the hydrocyclone.

A backflow between the hydrocyclone discharge and suction compartments of at least 100 gpm usually ensures adequate processing. Estimations based on rig circulation rates are usually inadequate if the plumbing is not arranged properly.

GN Solids Control usually choose 3 phase separation for HDD and other compact system for HDD and other similar projects. To keep a better result for the drilling fluids separation. Specially designed cones ensure the result.

Keep tune to GN Decanter Centrifuge.

There are three types of decanter centrifuge widely used in drilling field:
1. Small centrifuges – the diameter is less than 14 inch (355mm,356mm) and its volume capacity is 10 – 100 gpm (2.3-22.7 cubic meters).
2. Medium centrifuges – the diameter is around 15-16 inch (381mm,406mm) and its volume capacity is 30 – 150 gpm (6.8-34.1 cubic meters).
3. Large centrifuges – the diameter is more than 16 inch (406mm) and its volume capacity is 60 – 200 gpm (13.6-45.5 cubic meters).

MI Swaco CD-600

The M-I SWACO CD-600* CENTRIFUGE can remove LGS at much higher flow rates than can be achieved with the smaller machines. Because of its large diameter bowl (600 mm) and high bowl speed (up to 2800 rpm), the unit can accelerate the particles at 2600 Gs.

In summary, thermal desorption of oil from drilling cuttings for environmentally acceptable disposal of the cuttings was identified as an option in the early 1990s. The technology used for this purpose evolved significantly in the intervening years. In Europe and South America, the processed cuttings typically measure less than 1% of Total Petroleum Hydrocarbons (TPH) before disposal in landfills and this was the target selected for the subject project.

Regulatory agencies in other areas have also set standards for the levels of TPH in cuttings prior to disposal or discharge to the environment. Some processes do not require thermal desorption technologies. For example, in the Gulf of Mexico the discharge of cuttings with TPH levels of either 6.9% or 9.4% by weight, depending on the synthetic oil selected, is allowed if other toxicity and biodegradation standards are met or exceeded.

These levels of oil on cuttings can be attained with mechanical systems. However, the trend in environmental regulations is toward greater stringency and therefore an increased demand for minimal TPH levels in treated cuttings will drive the development of more oil-removal technologies.

All thermal desorption processes evaporate the oil and water from the cuttings. The heat required to evaporate the oil and water provides enough energy to remove and separate emulsified oil as well. Free and emulsified oil and water are removed by distillation, and in the process, water evaporates first to produce steam. Oil has a higher boiling point and evaporates after the water. The production of steam can also assist in lowering the boiling point of oil.

The goal is to produce oil-free (or ultra-low TPH) solids for disposal by distilling off oils from the cuttings and recovering oil to be re-used for drilling fluid.

GN Solids Control have done a lot of work to optimize the system for the application of HDD project. And we get we paid, after trial our first mud system, CPP like all other clients, repeat their orders, 20 more, 10 more, and repeated.

Each horizontal drilling project is unique, with its own set of challenges. Sometimes these challenges relate to logistics, such as site layout or accessibility. Other sites may present challenges related to a difficult bore profile or infrastructure that complicates navigation. Still others required careful planning and preparation to work within strict administrative rules or regulations. Finally, and generally most significantly, some sites pose challenges imposed by the geology or lithology of the formations to be drilled. Each site has the potential to present a combination of these challenges, particularly those associated with geological conditions.

Then back to the question, how to choose a compact HDD mud system. Firstly, if you know a professional HDD mud system company, no such question, ask them for a proposal. GN Solids Control usually is a good choice.

Secondly, ask your self a few questions to recheck your supplier:

1. Did they solve all my questions right now? Any more proposal more than my expected? Like:

2. A professional solution.

3. A lot of customer list.

Download GN Solids Control presentation here, if you want the one with customer names, contact GN consultants.

In England, HSE is undertaking a campaign to increase compliance with legal requirements for increase compliance with legal requirements for drill rig and pile rig guarding, HDD is an important part of it.

There are complete introduction for usual rigs, small rigs, large rigs. Key parts of rig to which access should be prevented:  Stake down augers.

In Australia, usually a HDD drilling company will hire one HSE consultant or have one HSE engineer to take part in all process.

As far as we know in Singapore, Hongkong, America, and so on, have special requirements about HSE.

As list in the checklist for HDD in HSE (UK), One important part is: Suitable and Sufficient Risk Assessments and safe system of work developed, Site-specific authorised Permit to drill, Method Statement, Plant Electrical Earthing arrangements satisfactory, site communication arrangements.

GN have cooperated with a lot of Australian clients for HDD project, and also cooperated with CPP for a lot of foreign projects, freely to contact for professional advice.
