As one of the few API and ISO certified manufacturer,GN Solids Control design various drilling mud weighting equipment and system for Petroleum drilling,Micro-Tunneling,Horizontal direction Drilling,downhole drilling etc.

To know why people need to weight the drilling mud as operation goes,firstly,we need to know

Composition of drilling mud

Water-based drilling mud most commonly consists of bentonite clay (gel) with additives such as barium sulfate (barite), calcium

carbonate (chalk) or hematite. Various thickeners are used to influence the viscosity of the fluid, e.g. xanthan gum, guar gum, glycol, carboxymethylcellulose, polyanionic cellulose (PAC), or starch. In turn, deflocculants are used to reduce viscosity of clay-based muds; anionic polyelectrolytes (e.g. acrylates, polyphosphates, lignosulfonates (Lig) or tannic acid derivates such as Quebracho) are frequently used. Red mud was the name for a Quebracho-based mixture, named after the color of the red tannic acid salts; it was commonly used in 1940s to 1950s, then was made obsolete when lignosulfonates became available. Other components are added to provide various specific functional characteristics as listed above.

While operation goes,some material as composed of the drilling mud above may lose.To keep the balance of the drilling mud,drillers need to weight the drilling mud by adding chemicals into the mud.Usually,a complete drilling mud weighting system is consist of following equipment or accessories.

GN Solids Control design and manufacturer drilling mud system specifically for CSG (Coal Seam Gas) Drilling Mud Cleaning System.
The CSG (Coal Seam Gas) exploration and drilling is very popular in Australia.GN Solids Control has exported mud system to Australia for CSG drilling contractors.

About CSG (Coal Seam Gas)
As an end-use product, CSG is the same as natural gas, and can be utilised in all natural gas appliances and commercial applications.The difference between CSG and other natural gas is mostly how it occurs in nature. CSG collects in the coal seam by bonding to the surface of coal particles, whereas other natural gas is stored in the pore spaces between grains of sandstone or similar rock.

Coal seams in the ground are generally filled with water, and it is the pressure of the water that keeps the gas adsorbed as a thin film on the surface of the coal. The cleats, the fracture system of coal, may be interconnected and permeable. In a high quality CSG deposit the cleats are permeable enough to allow gas and water to flow freely through them.

The level of gas produced from a coal bed is dependent on the thickness of the coal, gas content, permeability and the depth of the coal seam.The coal seams that can produce CSG economically are usually between 200m to 1,000m below the surface.

As described by GN Solids Control Clients,in CSG drilling,the drilling mud usually has much fine solids sometimes up to 80% solids.Aslo the CSG drilling is very fast. Continue reading “CSG (Coal Seam Gas) Drilling Mud System”

As an ISO & API Certified company specilize in mud circulation system.Following GN Solids Control introduction of mud circulation systems.
Function of Mud Circulation System
A fluid called mud circulates through the drilling bit as it cuts through rock. The fluid lubricates the bit, removes rock cuttings, stabilizes the wall around the hole, and controls the pressure in the wellbore. The mud is a suspension of chemicals and minerals, such as bentonite clay in water or sometimes oil.

Processing of Mud Circulation System
Workers blend the mixture in the mud-mixing shack. The mud pumps push the fluid up the standpipe and into the drill pipe through the kelly, or through fittings in a top drive mechanism. After passing through the drill bit, the mud and cuttings circulate back to the surface through the space outside the pipe, known as the annulus, and into the return line.

The shale shaker, a vibrating screen, then separates the cuttings from the mud. The cuttings flow into lined pits or tanks, while the drilling mud flows through the de-silter and is recirculated. More fluid is added through the mixer as the drilling progresses to greater depths. When drilling is completed, the remaining fluid is trucked away for disposal or reuse at another site.

This post GN Solids Control will share with your our configuration of 1000 GPM to 1500GPM mud cleaning system for HDD(Horizontal Directional Drilling).

Main Benefits of the mud cleaning system:

• Cost effective method of re-cycling drilling muds.
• Reduces cost of supplying fresh mud.
• Avoids cost of disposing of liquid waste.
• Cut point of 7 micron removes particles which damage triplex pumps, whilst leaving the useful bentonite particles in suspension for re-use.
• The discharge from the cleaner is virtually dry, dramatically reducing disposal costs.

  

• Reliable and durable design, based on 20 years of field experience Engineer
• High speed continuous mixing facility incorporated.

Detailed process features:

General:

A) Cleaning Tank is divided into 3 compartment,1# Shaker compartment,2# De-sander compartment,3# De-silter compartment.

B) Mixing Tank is divided into 3 compartment,4# Intermediate compartment ,5# Centrifuge compartment,6# Mixing compartment.

1)Flexible feeding of mud from mud pit to Shale Shaker.

Two 100YZ160-38B submersible slurry pump feed slurry from mud pit to 3 each Shale Shaker at capacity of 1450GPM .Slurry pump is made from Cr26 Abrasion resistant Alloy which allow users to pump high solids content fluids. Each slurry pump connected with fluids divider of Shale shaker separately by 4 inch hoses with quick connectors. Slurry pumps are controlled separately in control panel in cleaning tank & and drillers shack. The flow capacity can be controlled by valve separately.

Decanter centrifuge is one part of the solids control system, and sometimes it is used separately, for diamond drilling works, some coring works in mining industry, other drilling works with small debries.

As we know, in solids control system for oil&gas drilling, after the third phase, the desilter, debries bigger than 30 (15-47) microns are cleared out.

Once a client told us that they use mi swaco 414 with tank as a centrifuge system for their diamond drilling, we find we producing the equivalent one, LW220. So after proved with our experenced engineer, then re-researched by the cooperation universities, we manufactured our own centrifuge system for diamond drilling. LW220 with mud tank. Rugged design, compact body, efficient solution.

The differential gear type is mechanical differential, and the treating capactity is ≤ 150lpm, which means the maximun capacity is 150lpm, and you even can use this to handal the drilling mud with about 20lpm.  Other specific is as shown below:

Drum diameter: 220mm

Rotary speed:1500~4800rpm (Variable Speed)

Extruder rate L/D: 4.3

Separation factor: 2800G

Motor power(explosion proof)：main power：11kw；Assistant motor: 5.5kw

Dimension ：2020×1080×755mm

Weight ：1000kg；

Operation period：continuously 24hours

Well servicing rig is also called workover drilling rig,GN Solids Control design and supply well service drilling rig mud system clients all around the world.

Well servicing  RIGS: Land-based workover rigs (commonly referred to as well servicing rigs) consist of a mobile carrier, engine,

drawworks and a mast. The primary function of a workover(Servicing) rig is to act as a hoist so that pipe, sucker rods and down-hole equipment can be run into and out of a well. Land-based workover(Servicing) rigs are easier to move between well sites and different geographical areas of operations than drilling rigs. Typically, the rigs are self-propelled and have less auxillary equipment to move. Because of size and cost considerations, workover(Servicing) rigs are used for these operations rather than the larger drilling rigs.

Well servicing drilling mud systems:

• Repeat order for workover rig solids control equipment from Kuwait company

• 2 mud tank systems for workover(Servicing) drilling rig to Indonesia

GN shipped nearly 10 orders solids control equipment From September,2010 to October,2010.And most of the shipment are from GN international sales department.In 2010,GN Solids Control has broken into another new countries or areas.
