The North South africa countries active in essential oil drilling including Egypt, Algeria. Libya have lots of necessary oil reserve, but the government is simply not stable and situation is appropricate for stable business development. This is certainly really great pity for our business. Tunis is only big with area, really not energetic in oil drilling exercise. I don’t know why. We should talk about Egypt and Algeria market. We just fixed registration with Egypt most significant drilling company, and if the merchandise is qualified, we will assist them in next several years. We hope so. In Algeria, it is really hard market the rest of the oil drilling activity is there. Every purchase practice need tender.
The Gulf Africa top oil land is Nigeria. We have foreign trade over 2million dollar devices to Nigeria in the past a. And one drilling company have purchased 3 sets vertical cuttings dryer with regard to drilling waste management in addition to 10 sets of decanter centrifuge for solids control. The many equipment have been working for above 2 years and the client will be satisfied with the working performance. Hopefully the world crude oil value will go up to 80 money, and our business will even come up soon. Other To the west Africa countries, we have some clients.
So , as a essential oil equipment supplier, we count on Egypt, Algeria and Nigeria in a large degree. Trust the business will restore in the near future. Best regards.

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

Liquid mud plant

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 realise it: it is difficult to control the time. which equipment should be used? And should it be processed? The liquid mud plant need to use huge quality of pure water to make qualified drilling 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. 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.

GN Solids Control mud system shipping to Thailand

GN Solids Control have a commonly clients from overseas marketplace. Recently, we have one consumer from Thailand bought one placed 500gpm mud cleaning system for HDD project.

3) Decanter centrifuge
For necessary oil drilling field, Most of consumer will need 2 sets decanter centrifuge for operation. Often the dual centrifuge system like one set high speed decanter centrifuge for lower gravitational pressure solids removal; one placed lower speed or midst speed decanter centrifuge to get high gravity solids treatment; screw pump for giving the dual centrifuge are drilling to be also concluded, as well as telescopic high skid for setting up.
But for HDD field, usually clients only require decanter centrifuge in big project with much complex geomatics issue. Most of client will select GNLW452 middle speed centrifuge for proper use. Currently for HDD, the drilling depth will not so deeply as oil drilling, along with high speed decanter centrifuge is not really necessary. Middle speed along with big treating capacity regarding 1800RPM bowl speed could work perfectly for these kinds of task.
