GN Mud Recycling System For HDD Sailing to Middle East

Ever since its establishment 9 years ago, GN has been providing following products and solids control lines for following industries:

  1. Oil and gas drilling solids control system including 4 phase of solids control and 5 phase cleaning equipment, the shale shaker, desander cones, desilter cones, decanter centrifuge and the various feeding pumps for those equipment, like centrifugal pumps, submersible slurry pumps, mono pumps and shearing pumps. And also, the vacuum degasser is within GN’s product range.
  2. Mud cleaning system for HDD projects. The main equipment used for HDD mud recycling systems are similar as the oil and gas solids control systems, especially recently, more and more centrifuges are used for HDD projects after the desilter A slight different is that, in case of oil and gas solids control system, the mud falls directly from the well mouth to the shale shaker, while in HDD project, there is a submersible slurry pump used for transporting the mud from the mud pit to the shale shaker. GN shale shakers are designed differently on the buffer box accordingly.
  3. Desander plant or slurry plant for Trenchless projects or TBM projects. The mud system or so called desander plant are similar with the HDD projects’ mud recycling systems. And the separation equipment to be used are chosen by clients’ respect. In some cases, the TBM Mud recycling system even use a decanter centrifuge or a dewatering system.

How to reduce the operation cost of a liquid mud plant for oil and gas drilling field

Liquid mud plant is a supporting base for oil and gas drilling rigs. Normally, a liquid mud plant will service some oil rigs nearby. It is essential to keep the liquid mud plant fluently and smoothly. Once there is a urgent request from drilling rigs, liquid mud plant should mix and offer qualified drilling fluids immediately.

Liquid mud plant is mostly used to make oil base mud. Diesel oil is widely stocked and used here as base oil. It has pollution to the environment. Government has strict rules and prohibits any oil leakage to environment.

So there will be a dam around the liquid mud plant to prevent any leakage come out of the liquid mud plant base. In normal conditions, it is ok. But when there is a raining, things will be difficult. As the government has rules, the raining water in the initial 15 minutes within the dam should be treated.


But there is so many difficult to relies it: it is difficult to control the time. which solids control equipment should be used? And should it be processed? The liquid mud plant need to use huge quality of pure water to make qualified mud. Even for the oil based mud, they need to use pure water. It should be a good idea to reuse the rain water for mud mixing system . If the rain water can be used to make oil based mud, it will be a big save. The liquid mud plant can save cost on rain water treatment, as well as water for mud mixing.

Another big cost is the storage of old drilling fluids. After some circulation, the drilling fluids will be not qualified for drilling, as there are too much ultra fine solids inside, the mud is weighted. Decanter centrifuge is very important at this stage, It can remove the fine solids inside the old drilling fluids and make it qualified to drilling rigs. The quality of liquid mud plant depends on the mud storage capacity of each liquid mud plant. It the old mud can be treated on time after arrive the plant site, they can save cost on old mud storage.

How to choose the suitable drilling waste management system

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.

drilling waste management system

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.

2) Vertical cuttings dryer

Vertical cuttings dryer is to deal with the waste discharge from shale shaker, recycle the valuable drilling fluids and dry the solids. This vertical dryer is very good use for oil based mud drilling cuttings. The OOC can reduce down to below 5%, much convenient for following transportation or next stage treatment.

3) High G drying shaker

If for water based mud, most of client choose High G drying shaker. The performance of High G drying shaker is not that good as vertical cuttings dryer, but much lower purchase cost and maintenance cost. GNZS594HGE-LD HIGH G drying shaker is used in many different drilling rig site. And the high working efficiency performance and less maintenance give good reputation for GN Solids Control.

Substantial Configuration HDD Mud System with Centrifuge Unit to get Heavy Mud

Most of the apaisado directional mud cleaning system is not really equipped with decanter centrifuge unit as using the 3-phase separation system which include shale shaker, de-sander and de-silter unit, it can work sufficient for removing the solids from drilling fluids. Centrifuge is relative high cost, also is a reason the drilling company doesn’t equip it inside mud system.
However , for many high request drilling situation, the driller may use often the heavy mud for a great deal better drilling performance. Sometimes the particular drillers add the selected chemicals to make the drilling mud heavier so that the mud can certainly better protect the walls of the drilling hole. In case the driller went to drill an additional well, the heavy compounds need to be separated, and then typically the centrifuge could be used to do this kind of job. In some other circumstances, after many times recycling in the drilling mud, there is considerably ultra fine solid allergens that cannot be removed from the shale shaker and cyclone model, and then the centrifuge model is needed.

GN Solids Control possesses nearly 10 years in making the drilling mud system for HDD projects. This manner mud cleaning system must be compact structure and easy intended for transportation. See the picture on this page, both the de-sander and de-silter unit are equipped with under stream shaker for drying typically the discharged solids. The shale shakers used are 2-layer screen design. The bottom layer screen is used as primary shaker and upper layer screen to dry the discharges out of your cyclone units. This style greatly reduces the impact of the mud system. And all sorts of mud tank top surface equipment tend to be pre-installed on a frame using same base dimension while storage tank. When transportation the mud mixing system, the actual shale shaker and decanter centrifuge models could be removed by moving the frame for quickly disassemble. With the frame, the device could be easily transported simply by flat bed trailer.
GN can provide both standard as well as customized HDD mud system for clients. Just send out us your request, after which you will get a satisfying as well as cost effective solution.
