GN Solids Control provides standard and customized mud systems for No Dig Drilling areas. With these years’ fast development, GN Solids Control has provided hundreds of compact mud systems for HDD area.
GN Solids Control has 200GPM, 350GPM, 500 GPM and 1000PM mud system can be chose. Based on customer’s special demands, GN Solids Control also provides customized HDD mud recycling systems.

GN HDD mud treating systems are divided into two groups:
1. Economy Mud Recycling System: mud treating systems only have shakers and desander or desilters;
2. High Configuration Mud System: this type mud treating systems have storage tank and mixing tanks.
Today, we would like to give you an introduction based on the working process of GNMS-500GL high configuration mud system.
The main equipments in GNMS-500GL system including: shaker, mud cleaner (with desander and desilter cyclones) and mixing tank.
A submersible pump is usually used to pump the mud to the GN shaker, which is GNZS703E-DE with 3 panels’ shaker screens assembled on it. Drilling mud separated by the shaker will fall off to the bottom tank, which will be feed by one centrifugal pump to the 10inch desander cyclones for the next phase separation. Then the 4 inch desilter cyclones will help to remove much finer solids most of them are above 25mircons.

From the working function, the first shaker and mud cleaner tank is also called shaker tank, while for the rest part it is called mixing and storage tank. Clean drilling mud are stocking in the mixing tank, by adding some chemicals GN Solids Control mud systems provides effective drilling mud to the drilling rig. These drilling mud can be reused again.
All the above equipments can be put in one standard container, which will help to save shipping freight. As shaker screens are wearable parts when using in the shaker, GN Solids Control also manufactures the most cost effective shaker screens.

How to choose the suitable drilling waste management system

Leave a reply

As more and more countries start to control the drilling waste and improve the standard of waste discharge in oil and gas drilling field, drilling waste management becomes more and more popular and important. Many companies have to or want to start their business for drilling waste management. But many clients do not have experience on it. They do not know how to choose the suitable equipment or systems for their activities.

As a worldwide famous brand on mud solids control and drilling waste management, GN Solids Control start its research and development department for drilling waste management and industry waste management for many years. Below is a brief introduction of normal drilling waste management equipment to help the users make decision.

1) High G drying shaker.

It is also named High G dryer, cuttings dryer. It utilizes high G force up to 8.0G to dry the cuttings. If there are big particles in the solids waste, high G shaker is requested. It can remove big size solids and even metal particles. The high G shaker can remove solids above 100 microns.

It is mainly used to treat the water base mud and water based mud cuttings. It can also be used for oil based mud treatment in some cases.

When the high G drying shale shaker is used to treat oil based mud and cuttings, it can only reduce the oil on cuttings (OOC) to 10 ~ 15%.

2) Vertical cuttings dryer

It is also called vertical centrifuge or vortex dryer. It utilizes centrifugal force up to 420G to separate the fine solids and recovery the usable drilling fluids. The screen opening of VG dryer is 0.5mm, 0.35mm and 0.25mm. It cannot allow big size sizes solids or metal particles; otherwise, it will be broken.

Vertical cuttings dryer is mainly used for oil base mud and cuttings. It can reduce the oil on cuttings to 3 ~ 5%. In this case, the solids discharge is on a very dry condition and it is easy for shipment. And the solids with 3~5% OOC can be discharged directly in many countries. If not, it is also easy for next treatment.

3) High speed centrifuge and big bowl decanter centrifuge

It utilizes the high centrifugal force to separate the very fine solids to 2～5 microns. It is used after high G shaker and vertical cuttings dryer, for further separation.

There are many other equipment used for drilling waste management, we will introduce in next file.

GN Solids Control has provided many dredging systems for our clients. Almost all the GN dredging mud systems are customized in order to meet customers’ needs perfectly well. GN also manufactures standard mud systems for dredging.
For dredging, typical slurries have the following composition ranges. There are different layers in the sediment. For natural lakes, coarse debris is found near the river inlet and fine material builds up near the outlet. UAT customers also use the dredges for many man-made water bodies that can have unusual layers of materials.
Solids: 0-30%, typically 5-20%
Coarse debris (>6mm): 0-70%
Sands (0.07 – 6 mm): 10-100%
Clays/Silts/Organics (<0.07 mm): 0-100%

GN Dredging System
It is better to size the dewatering equipment for the majority of production, instead of the most difficult requirements. Design the dewatering equipment to handle only the 20% MAX solids slurry at the specified flow rates; the dredger using UAT’s small equipment can decrease the flow rate for the occasions where they are processing high-solids slurries.
1. GN Solids Control manufactures a scalper in the system before sending the sands/clays/silts to the shale shaker. Coarse debris includes rocks up to 10cm, trash, leaves, twigs, and sea shells. Screens on GN scalper are made from metal or polyurethane.
2. For the 4 stages separation, after separated by the scalper, GN Solids Control provides one shaker for second phase separation. The shaker will be a double deck shaker with different API Nos. shaker screens.
3. GN cyclones are used based on the mud they are separating. Bottom shaker will be the same as the shaker using in the front.
