Just last week, GN Solids Control has finished a compact mud recycling unit, with full steps for separation for one of the largest oil giants in China. This system is to be transported to the jobsite by end of this year.

This system has 4 steps of separation, including:

1. GNZS703F. Shale shakers are always the first step for separation, because of GN shakers’ high G force and accurate API complied shaker screens, this shale shaker can efficiently separate out all particles larger than 100 microns, there in hence to help with prolonging the service life of the centrifugal pump after the shaker.

2. GNZJ703F-1S8N Mud Cleaner. Mud cleaner is a combined machine of desander and desilter, at a smaller foot print. It uses interchangeable shaker screens as GNZS703F, 2 centrifugal pumps are used to feed the desander and desilter respectively.

3. GNSP series Centrifugal pumps are also GN’s own products. For material choosing, GN used the high quality anti-weary material as pump body material by hard ductile iron alloy, and the main pump body is thicker than other manufacturers’. All GNSB series centrifugal pumps are using stainless steel mechanical seals.

4. Tank and skid for above mentioned equipment. Above mentioned equipment are located as 2 blocks. One block is a skid with lifting and anchoring corners just as a 20ft container, and the shale shaker and mud cleaner are located in the skid during transportation and operation. That design facilitates the operator for transportation or lifting the whole skid onto a tank, no to adjust each equipment or pipeline’s position.

5. A tank with compartments are designed to storage the mud from the shaker and from the desander/desilter. On below the tank, there are some slots for installing the centrifugal pumps. The whole outsize of the tank is also same as a 20ft container with container corners for lifting.

Although in recent years, a large percentage of GN Solids Control’s products are sold to different industries besides the solids control projects, solids control systems and equipment are still GN’s traditional business of which GN’s brand is still quite well known and widely accepted. And GN customers in oil and gas solids control industry are introducing some of GN new products into their traditional works.

gn powerful vacuum pumps

vacuum pumps

Vacuum pump is one of the most popular products of recent 2 years ever since GN firstly showed one of such pump with a capacity of 40 cbm/hr in CIPPE Oil Show in Beijing for year 2017. In the following year, also in CIPPE oil show, GN showed another model alongside with GNSP-40A, which had half capacity and need half air consumption, with a compact and movable design, the GNSP-20A.

The vacuum pumps are quite powerful small machine. It could handle a material with quite large particles size, as long as the particle could pass the hose’s diameter, and with some liquidate. Such like the sands and small stones. Talking about transportation power, take the GNSP-40A for instance, it can suck the material from 50 meters away and deliver it to more than 100 meters away. Now it is widely used in oily sludge separation systems in refineries, in chemical industries, for tank bottom cleaning works, and for drilling cuttings transfer in oil and gas drilling.

Comparing with other pump types, like the GNSB series centrifugal pumps GN provides for the desander/desilter feeding, for the jet mud mixing, or with the submersible slurry pumps for feeding the centrifuge and sucking mud from mud pit, the vacuum pump, although powerful, it has some shortcoming like non continuous operating. But GN engineers are working on it, in order to find some solution. Let’s see.

As the leading manufacturer of solids control and waste management equipment and also a professional separation solution provider, GN Solids Control has a products line covers the separation procedures and also the transferring procedures. GN Solids Control provides various pump for different applications including following:
1. Centrifugal pump, centrifugal pump is the most commonly used pumps in the oil and gas solids control industry, which is used for feeding the desander and desilter cones, for compensate the mud loss from the trip tank as trip pump, feed pump for the mud mixing unit for the mixing application and also plays as a role of charging pump. GN Solids Control produces the full range of centrifugal pumps from75kw to 7.5kw, equipped with mechanical seal, with high quality material for longer service life. All parts of GN series centrifugal pumps are interchangeable with Mission Magnum.

2. GN shear pump. Shear pump is not so commonly used as centrifugal pump. They are only used for shearing some special chemicals which are needed for large horsepower oil and gas drilling rigs.
3. Submersible Slurry pump. Submersible slurry pump’s applications in GN solids’ mud system and mud units are mainly those two: one is for centrifuge feeding in solids control systems like for the barite recovery and extra fine particle separation, or for the HDD mud recycling units, it is the second to none choice for transfer slurry from the mud pit to the mud system.
4. Vacuum pump. GN series vacuum pumps are the newest member among GN pumps. But it gained highest attention ever since its birth. Comparing with other pumps, the most obvious difference is that it has no motor. It is fully air driven and has less limitation for the solids size. In practice, it could handle material with particle size only a bit smaller than it’s pipeline diameter.

Per experiences and calculated data, the drilling liquid occupies in any well drilling is between 4 percentage to 10 percentages, no matter in onshore drillings or offshore drillings. Considering its effects on the drilling operation performance, which occupies nearly 50 percentages, the drilling fluid is quite vital to the drilling.

GN Waste Management Equipment

That’s why, a professional drilling manager has to have a professional team for the drilling mud services, or find a qualified drilling fluid service company. In practice, drilling companies or drilling contractors always focus on drilling work, and employing a subcontractor for the solids control system. Each drilling rig has eight systems connected to each other, among which, the solids control system is comparably independent. An expertized drilling fluid company has the right personnel and suitable equipment, and more important, they know how to treat the fluid well.

A professional oil service companies provide following services:
1. Solids control equipment and services. The solids control systems help to treat the drilling fluid directly from the well mouth. It contains three or four phases for separation, including the shale shaker as the first phase, the desander cones as the second phase, the desilter cones as the third. Some include the decanter centrifuge as the forth one. In most solids control systems, there are mixing unit for adding more chemicals into the fluid when necessary.
2. Drilling cuttings waste management systems, in some countries, this part is also regarded as a part of solids control, because this is also for treating the solids from the drilling fluid. Those systems always contains the vertical cuttings dryer, the high G drying shaker and the decanter centrifuge.
3. Drilling fluid waste management, it is the further treatment for the drilling fluid. As the fluid has been used for a long time, this system uses some chemicals to flocculate the extra fine particles into larger ones before being separated out by a decanter centrifuge.
As one of the leading manufacturers of solids control and waste management, GN Solids Control has been providing lots of oil service companies in the world for all above mentioned systems and equipment. For more information or a formal quotation, welcome to contact GN directly.
