GN had a large order from Kuwait client

GN Solids Control Co continues to be focusing on solids control devices and drilling waste management systems for several years, and lots of customers are keep get these solids control devices from GN each year because of the superb quality and be assured post sales maintenance.

Lately, GN Solids Control Co provides many teams of solids control devices for the client in Kuwait. This client has bought GN devices for his or her work over drilling rig. Whenever we cooperate with client at the start, we demonstrated our purpose to possess win-win cooperation by supplying solids control devices with higher quality.

Last year they gave us a sizable order which including 8 teams of GN shale shakers (the kind is GNZS594E-HB), 4 teams of GN vacuum degassers (the kind is GNZCQ 270), 4 teams of GN desander, 4 teams of GN desilter, 32 teams of GN centrifugal pumps in addition to 48 teams of GN mud agitators and eight teams of GN mud hopper.

For that shale shaker, we designed and manufactured a mud distributor for 2 teams of shale shakers, here it is called dual connection GN shale shaker. So our client has 4 groups Dual Shaker, with a large dealing with capacity, because even some GN shale shaker can dealing with the drilling liquids up to 616 GPM m3/h.

Depending on the above solids control devices, it's apparent to understand this can be a three phase solids control system our client really wants to use.

1. Shale Shaker

GN shale shaker can separate solids to 100 microns. For this kind of GNZS594, the dimension of shaker screens is 585mm X 1165mm, therefore the screens are exchangeable with Swaco Mongoose screens.

2. Vacuum Degasser

The mud originate from shaker will be delivered to vacuum degasser to get rid of the environment in drilling liquids. By utilizing GN vacuum degasser, the drilling mud could be stored inside a steady viscosity.

3. Desander and Desilter

GN desander and desilter can separate solids to twenty microns. The cyclones on desander and desilter are made from PU that is really useful to possess a very long time lifespan.

Drilling mud tank design concepts

The level of drilling mud tank must be big enough to support the utmost cycle amount of the drilling mud within the oil well drilling process, and also have enough mud reserve capacity.  Simultaneously the tank also provides the capabilities of taking part in cycle and manipulating the oil well just in case of the emergency. Recently, using the developing from the global marketplaces and also the growing need for drilling fluid solids control systems by drilling craft, the drilling mud tanks possess the need for boost the volume size.

When the drilling mud tank size is increasing, the price of moving drill rig and drilling fluid is going to be elevated too. Because of this, reasonable cubage may be the goal which went after by finish-customers. Based on the well drilling practice by many people years previously, it uses the technique of calculation of drilled well whole cubage or drilled well casing cubage to calculate the effective cubic consists of from the drilling fluid solids control system generally. The outcomes of these two techniques of calculation are believed.

In some solids control system, how big the only drilling mud tank and the quantity of the cycle  within the tank are made the decision through the height from the derrick substructure, the neighborhood transportation situation, and also the effective dealing with amount of the drill rig needed, etc...

The top mud tank must have enough space to set up needed solids control tools, mud agitator and drill rig transfer pumps. Furthermore, the configurations from the connected flow type of the drilling mud, add-ons, pump inhalation, water pipeline and just various tools needs be thought. The level of every storage mainly rely on the set-up space of solids control tools like shale shaker, desander, desilter, decanter centrifuge, along with other auxiliary devices too.

The Primary Safe Unit ---- Mud Gas Separator

We're able to begin to see the mud gas separating set up in many drilling rig jobsite. Regarding to complicated geologic atmosphere of drilling site, mud gas separator can be used for separating the hazardous gas in the drilling liquids. Not just mud gas separator can be used for oil & gas drilling site, but it is also requested the deep mining drilling jobsite.

GN mud gas separator’s working principle

The drilling liquids/mud from lower hole adopts mud gas separator (poor boy degasser).Because of the gravity pressure; the mud drops lower around the 1000mm diameter vessel of poor boy degasser. Mud collides on buffer plate of pipe therefore the harmful gas is going to be relieved in the drilling liquids. Clearly, gas flows to the peak of 8 inch vent line that is associated with the flare igniter to lose out. Normally, flare ignition system is about 160 foot from the poor boy degasser to make sure the safe distance burning. Meanwhile, the mud would go lower and gathered at the end of mud gas separator, and subsequently flow towards the in to the solids control system including shale shaker, desander, desilter and decanter centrifuge etc

Why we decide GN mud gas separator?

1.GN is recognized world-wide for precision, sturdiness, from simple to complex and standard to personalize to be able to design and manufacture probably the most reliable mud gas separator .

Poor boy degasser for oil & gas drilling

Functions of Poor boy degasser for oil & gas drilling

Poor boy degasser, also called mud gas separately, it is a normal equipment in mud solids control system for onshore and offshore rigs. We can see from the name, the main function of poor boy degasser is to separate gas from drilling mud. There normally big quality air bubble in the drilling mud. The air bubble may damage the solids control equipment, like mud cleaner, desander, desilter. Another reason, and the most important reason, there normally dangerous gas consisted in the air bubble, if it is comes out with mud and spread the environment, it will make pollution and hurt the operation people at jobsite.

Different design Poor boy degasser for onshore and offshore oil & gas drilling

There mainly 2 types design Poor boy degasser for onshore and offshore oil & gas drilling.

Design 1: Atmosphere type poor boy degasser

Features of Atmosphere type poor boy degasser: there will be 5~10 m or more longer vent line on top of poor boy degasser. It is used to pipe the gas into the atmosphere directly. 

Design 2: Ignition type poor boy degasser

Features of Ignition type poor boy degasser: Ther dangerous gas in drilling mud is H2S. It is combustible gas. After fire, it changes out to harmless gas and can be discharged directly. There will be 50m ~ 100m vent line to guide the gas to remote area. There will be a flare igniter connected with the vent line and fire the gas while it comes out. 

Flare ignition Device for Poor boy degasser for onshore and offshore oil & gas drilling

As a kind of security and environmental protection device, the flare igniter can be used to make the harmful gas ignited and burned to prevent it pollute environment. The flare ignition device, apart from being used in the refinery and gas distribution station, can be matched with Mud Gas Separator.
