GN Solids Control is one of the leading brands for solids control and waste management system, and second to none ranks among Chinese manufacturers in this industry. A lot of worldwide famous oil companies and oil drilling companies are using GN equipment and comprehensive solutions, including SINOPEC, CNPC and COSL. Recently, GN delivered main equipment for 2 sets of drilling cuttings waste management systems for CNPC.

GN BIG BOWL CENTRIFUGE FOR CNPC

Drilling cuttings are solids discharge from the drilling rig solids controls system, from the shakers, desander and desilters. After the solids control system’s first 3 phases separating, the drilling fluids are returned back to the system without the solids particle. But the separated-out particles are still too wet. For one thing, it is a waste for valuable drilling fluid. Secondly, it could damage to the environment if disposed directly. That’s why it is not only necessary but also mandatory to do some further treatment for the drilling cuttings.
GN Solids Control has zero discharge solutions for both WBM and OBM. And this order, combining the vertical cuttings dryer and decanter centrifuge, is for the oil based mud. A vertical cuttings dryer is specially designed for the oil based mud separation. GNCD930 series vertical cuttings dryers could dry the drilling cuttings to reach OOC value to 5%. The vertical cuttings dryer is running as the drying step of a washing machine. The vertical cuttings dryer is equipped with a screen basket with certain mesh number. Fluids pass the mesh and collected, while cuttings are stopped by mesh and falls down.
GNLW series decanter centrifuges with VFD control panels are used after the vertical cuttings dryer to remove the particles from 2 to 5 microns from the liquid. Most common model is GNLW363CG-VFD, a medium sized centrifuge with a high rotating speed. But for bigger treating capacity, GN has GNLW453C-VFD and GNLW553-VFD available, both of high rotating speed while bowl sizes are respectively 18 inch and 22 inch. In this project, clients chose GNLW453C-VFD.
Pls contact GN for more information.

A solidification unit or called solidification system is an efficient and economic solution for the treatment of drilling cuttings from both oil based mud and water based mud. Besides, it could also handle the sludge from some cuttings or waste pit. The principle is not so complicated, but the performance and continuous working ability are defining a solidification unit.

GN newest solidification unit ready for delivery

Since three years ago when GN Solids Control firstly designed and put into use the first set of GNGH Solidification unit, with the valuable feedbacks and experiences from both domestic China and abroad, GN improved the solidification unit several times. In a result, it is now more human oriented and easier to operate. This ready for delivery solidification unit is a newly designed one, and it would be its first show on client’s jobsite in a few days. It has following features comparing with previous design:

 

GN Solidification Unit System
1. It is more compact than before, with a smaller cuttings feeding hopper just above the coulter mixer the solidification unit itself are changed from two pieces into one piece. It is easier for transportation and later rig up on jobsite after transportation.
2. This new one is automatically controlled by a PLC control panel. All electrical components from brand Schneider, ABB or Siemens. Main operating data could be seen clearly on the screen and touching screen is easy for operators to control.
3. Mixing time could be controlled automatically and manually. Comparing with last model, this one is equipped with an electrical valve on discharge port of the unit, by using this, the operator could control the time period for the material to stay in the mixer for a better and adjustable mixing result.
4. Three VFD’s for the feeding. In this system, there are 3 feeding hoppers, all of which are VFD controlled by the control panel, then the fed proportion of chemicals, cement and cuttings could be adjusted according to the on time being conditions.
If you visit GN in recent days, you can check this system by yourself.

Recently, GN has produced for 2 different clients who worked for similar projects, with following equipment and solutions:
1. GN big bowl 22 inch diameter decanter centrifuges.
2. GN chemical dosing unit
3. GN standard containers.

GN CONTAINERIZED CENTRIFUGE AND DEWATERING

GN has been providing this design for many years, and the technology is quite mature:
1. GNDU2000 Chemical dosing unit. GN has been providing the chemical dosing unit or so called the dewatering unit for many years, since some of GN clients are using GN centrifuges as dewatering centrifuges and prefer GN to make compact design for them. A chemical dosing unit is used to treat the material by some chemical methods, for example, to add some material to reduce the viscosity of material, or to flocculate the extra fine particles into larger ones, which are suitable for centrifuge use.
2. GNLW553C-VFD decanter centrifuge is a big bowl decanter centrifuge with a treating capacity up t to 90 cbm per hour, and the rotating speed could reach 3000 rpm. It is quite suitable for drilling liquid management, especially being used together with chemical dosing system. Normally, the centrifuge treating capacity for material after flocculation would be greatly reduced, that’s why a big bowl centrifuge with a large treating capacity is always used for this application.
3. 20 ft containers for housing the centrifuge and chemical dosing system, which is quite popular design. For one thing, it is more convenient and easy to transport the system when the main equipment are in standard containers. Secondly, the containers give a shield to the equipment, providing a suitable temperature and clean condition. Thirdly, the 2 sets of 20 ft containers could be put one under another, in this way, less room to be occupied.
In this design, GN engineers designed the round shaped ladders for the upper located container with the big bowl decanter centrifuge, when transporting, the ladder could be put into the container.

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.
