As one of the leading brands among solids control manufacturers in the world, GN Solids Control is quite popular in many countries, including India. India has a high standard for choosing machines, and seldom Chinese solids control brands could be accepted by Indian market. Recently, GN Solids Control just delivered to India 2 sets of Tri-Shaker Units, together with 2 sets of mud cleaners with large capacity for oil and gas drilling industry.

Shale shaker is the first separating machine in a complete mud recycling system, which are used to separate the largest proportion of solids in the drilling fluids. By using the correct mesh size, a shaker can choose out all particles larger than 100 microns. GN has 2 models popular for oil and gas drilling, respectively with 4 pcs and 3 pcs of shaker screens, with capacity of 140cbm/hr and 120cbm/hr.
Normally, the 1 shaker solution is only suitable for small work-over rigs in oil and gas industry. Most of drillings require larger capacity, which means, at least 2 or 3 shakers are needed. In practice, end user can choose to locate 2 or 3 shakers together on the tank, with one big distributor to lead the fluids evenly to the 2 or 3 shakers. Also, end user can choose to locate the shakers on 1 skid, we call it twin shaker or tri-shaker unit. In this way, the total space is smaller and easier for end user to transport them or locate it as a whole at jobsite, for serving a big capacity.
Recently, GN just finished the manufacturing for 2 sets of such tri-shaker units for an Indian client, and for matching this capacity, they choose a mud cleaner with 3 desander cones and desilter cones. Desander cones are used for separating out particles of 40 microns, with 10 inch diameter cyclone, while desilters are of 4 inch diameter, for separating out particles larger than 20 microns.

Welcome to contact GN directly for more information.

Just days ago, GN Solids Control has finished the fabrication of a new mud recycling system for a drilling rig in domestic China. This system is not designed with a big capacity, but it has full separation equipment as a solids control system, as complete as it could, with following equipment:

  1. GNZS-703F shale shaker, 2 sets. GNZS-703F is especially designed for the oil and gas industry’s solids control applications. It has 3 pieces of composite material frame shaker screens, mesh cloths are made of high quality stainless steel SS316L. The special sealing design of GN’s patent helps a lot for avoiding the leaking of shaker. Besides this shaker model, GN also has another model for oil and gas drilling projects, with 4 pcs of shaker screens for a longer mud route and a bigger treating capacity. And GN has several other shaker models, including double deck shaker and mini shaker, all equipped with composite material frame screens as per API RP 13C standard.
  2. GNZJ-752F-2S Desander 1 set. It is a desander for a 1000GPM capacity, with a small underflow shaker. The desander is used for separating out the particles between 40 to 70 microns, normally, hydrocyclones larger than 8 inch diameter are called desanders, while smaller than 6 inch diameter are so called desilters. GN always use 10 inch desanders, and based on system requested treating capacity, quantities are always 1 set, 2 sets or 3.
  3. GNZJ-752-12N Desilter 1 set. The general structure of this desilter with underflow shaker is same as the desander, just with smaller size hydrocyclones. It is used for treating out particles larger than 20 microns.
  4. GNLW452 decanter centrifuge. It is a big bowl centrifuge with a small length diameter ratio. It is an economic model, serving a middle speed, for separating out particles between 5 to 7 microns.
    All above mentioned equipment, alongside with a mixing unit, are located on 2 mud tanks as a complete system. If you have same need or need other customized mud systems, welcome to contact us freely.

Xinjiang is located in most northwest of China, and in Xinjiang, there are rich oil reservations which brings to the region and country wealth. Meanwhile, Xinjiang Province is one of the most beautiful places in the world, where there are pretty meadows, great mountains, and clear lakes. In order to utilize the resources without bringing damage to the environment, the drilling companies and contractors must pay attention to how to safely and efficiently treat the drilling cuttings.
As per the different drilling fluids used for the oil and gas exploration, there are mainly 3 kinds of drilling fluids, water based mud, oil based mud and synthetic based mud. Among those 3, the oil based mud is the most popular one to be used. In this case, the oil based mud is used for the project in Xinjiang, and GN Solids Control supplied a proposal with following equipment for further treatment of drilling cuttings from oil based mud solids control system, from the shaker discharge:

  1. Vertical cuttings dryer GNCD930, which is designed for the oil based mud drilling cuttings, by using the suitable screen basket among 0.25mm,0.3mm and 0.5mm, the oil on cuttings could be reduced to 0.05% after discharge.
  2. Decanter centrifuge GNLW363-VFD, a middle sized high speed decanter centrifuge for further treatment of drilling cuttings saved from vertical cuttings dryer. The high speed centrifuge can efficiently remove the particles between 2 to 5 microns.
  3. Centrifuge feeding pump and vertical cuttings dryer flushing pump. Both pumps are screw pumps from Netsch brand, who has been cooperating with GN company for years.
  4. http://www.gnsolidscontrol.com/drilling-waste-managementScrew conveyors for transferring cuttings. GN has been making screw conveyors for years, and GN Screw conveyors are of high quality. Besides the screw conveyor, for drilling cuttings transferring, GN also has vacuum pump available.
    For more information, welcome to contact GN freely.

Each drilling rig need a complete set for drilling fluids clarification system. Such system can reduce the discharge of waste, for one thing, it can help with recovery of as much as drilling fluids, for second thing, the dried discharged solids are easier to be transported. Those functions seem more important in offshore projects than in land rigs.
For separation performance, there are not so many differences between the land rigs’ and the offshores’, but there are some more requests for offshores because of the off-land locations and the limited space. Normally, the solids control system for offshores should be better more compact, providing same capacity, and meanwhile, it has quite strict limit on total weight and quite high standards on lifting parts. For example, most of offshore components are requested to have DNV certificate designs or at list DNV certified lifting parts.
For this offshore project, GN Solids Control has provided to the client following equipment:

hdrpl
  1. One set of shale shaker. Shale shaker is one of GN’s core products. Each year, GN makes and sells more than 200 sets of shale shakers, some with 2 pcs of screens, most of 3 pcs of screens, while some using 4 pcs screens.
  2. One set of mud cleaner. With a compact design as combination of desander and desilters, mud cleaners are more and more popular than the single desander or desilters.
  3. Centrifugal degasser. This kind of degasser occupies smaller footprint than traditional vacuum degassers.
  4. GNLW Decanter centrifuge, as the 4th phase of separation equipment. It is a 18 inch big bowl decanter centrifuge.
    In this compact mud clarification unit, totally 5 steps separation and 4 steps solids control are involved. For more information, welcome to contact GN directly.

Solids control is the traditional product of GN Solids Control ever since GN’s establishment 12 years ago. And as all other Chinese manufacturers, GN’s products were mostly used for land rigs. But in recent years, as GN’s development and GN products’ improvement both in designs and in international certifications, GN’s equipment were accepted by more and more countries, even in Australia, Europe and USA, and, step by step, more and more offshore drilling contractors are using more and more GN equipment in their offshore platforms.
Just recently, GN finished a set of mud recycling system for an offshore contactor, as picture below. And this system is combined by full set of separation steps on a compact mud tank. Including:

hdrpl
  1. One set of shale shaker. GN has several optional shaker models, while mostly used for oil and gas drilling is GNZS703 and GNZS594, with 3 or 4 pieces of shaker screens. All GN shakers are equipped with composite material frame screens with long service life and accurate API numbers.
  2. GNZJ mud cleaner, a compact combination of desander and desilter, for separation particles of 70 microns and 40 microns, fed by centrifugal pumps.
  3. Centrifugal pumps for feeding the desander and desilter cyclones. GNSB Series centrifugal pumps are fully interchangeable with Misson Magnum pumps even in spare parts. And GN is using hard alloy for the main part of pump, like the pump casing and impeller for longer service life.
  4. Centrifugal degasser 1 set. Degasser is used to remove the bubbles inside drilling mud to protect the pumps or other equipment in next steps, and also help to increase the mud quality.
  5. Decanter centrifuge, for separating out the particles from 2 to 5 microns.

Above mentioned equipment are located on a mud tank with compact structure to ensure the easy transportation. Below the tank, there’s a screw conveyor for collecting the discharges.
If you need such system or similar system, please contact GN, we have professional engineers to give the most suitable design for your projects.
