GN Solids Control is one of the biggest mud cleaning system supplier in China, already sent a lot of mud cleaning system to all over the world, and biggest HDD contractor in China (CPP) is cooperating very well with GN.

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. Continue reading “HDD Mud Cleaning System Chinese Supplier”

In oil & gas field, have to use explosion proof motors in hazardous areas, and in China, usually choose YB2 series. And China also have a lot of world famous motor manufacturers.

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.

Shale drilling is becoming more and more popular, not only the reserves, the rising oil & gas price is also pushing us to do something. The Financial Times reports that as more big-name oil companies such as India’s GAIL Ltd, BP Plc, Exxon Mobil Corp. and Chevron Corp. invest in U.S. shale plays, the more the cost of drilling rights spikes.
In the Eagle Ford shale in Texas, drilling rights costs increased from around $4,000 an acre in 2010 to around $20,000 an acre at the end of 2011, according to IHS, the Financial Times reports.

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.

If you want to do more work than solids control, maybe you need a mud plant, used widely in offshore project, or waste management and so on. Also sometimes, all solids control part, solid liquid separation part being called plant.

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.

In oil drilling, hydrocyclones usually refer to 10 inch desander cones and 4 inch desilter cones. And use desander cones & desilter cones to separate different size solids content.

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.

Big bowl centrifuge is widely used in drilling mud solids control system, also in tunneling mud processing system. “As a professional company of solids control system, GN Solids (some clients like to take this for short) must sell it, we are expecting that”; as one customer told us. We should say, GN is doing this, hopefully it will be done early 2012.

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). Continue reading “Top Big Bowl Centrifuge Suppliers”

The use of thermal desorption technology or thermal desorption units (TDUs) to recover oil from drill cuttings has been well documented in the industry  and a detailed study of all available technology and processes was published by Halliburton in 2004.3

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.

We need a compact mud system. Usually it is the first sentence the HDD clients required, HDD is different from Oil & Gas drilling works, not so big rigs, and not so heavy work, and …

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.
