Drilling mud system

GN Solids Control is a specialist to manufacture full line solids control equipment, drilling waste management, and various sizes replacement shaker screens. In order to offer clients better support, GN Solids Control is flexible to offer customized equipment and solutions to meet clients request.

Recently, GN Solids Control made a customized drilling mud cleaner and mud gas separator for a drilling company. The equipment are customized color and mud customized design.

The capacity of the drilling mud cleaner is 1500GPM. It is a 3-in-1 combo type shale shaker, which is powered by 2 vibration motors. The motor brand can be Italy Oli or U.S. Martin. The drilling mud cleaner is combined by a under flow shale shaker, no. 3 desander cones and no. 12 desilter cones. The hydra cyclone assembly can be removed and the combo type shale shaker as a single deck shale shaker. The standard color of GN equipment is green, color code RAL 6024. For this project, it is customized gray color per client’s request.

Mud gas separator, which is also called as poor boy degasser, it is fully customized per the order. There are HSE standard ladders with guardrails all along the mud gas separator tank body. For easy movement and easy transportation, there are lifting frame along the mud gas separator. In this case, it can be easily lay down on the ground.

Besides drilling mud cleaner and mud gas separation, GN Solids Control can also make full line solids control equipment: shale shaker, desander, desilter, decanter centrifuge, jet mud mixer, mixing hopper, shearing and mixing hopper, centrifugal pump, screw pump, submersible slurry pump,etc…

And GN Solids Control is capable to make full line drilling cuttings treatment equipment: big bowl decanter centrifuge, vertical cuttings dryer, high G drying shaker, screw conveyor, drilling cuttings solidification unit, dewatering unit, etc…

Plus, GN Solids Control can make various size oil sludge separation equipment, and contaminated soil washing system.

If clients have any questions about GN equipment. Welcome to contact GN Solids Control freely.

GN Solids Control can make full package rapid liquid mud plant. Besides the metal components, GN Solids Control is capacity to supply all items including mud storage tanks, mud mixing tank and mud processing tank with all the manifolds, mixing equipment, processing equipment, level sensors, and central control room, etc…

Vertical storage tank is popular used at liquid mud plant. Compared with horizontal storage tank, vertical tank takes small footprint. And further more, vertical tank need less quantity mud gun than horizontal mud tank. A vertical tank only need to equip Qty 2 mud gun. But the same capacity horizontal mud tank will need at least double qty mud gun.

Last year, GN Solids Control supplied a liquid mud plant for a South America client. There are Qty 14 vertical mud tank and a package of mud mixing tank in the system. It is only part of a whole liquid mud plant. As the client is urgent to use some parts of the liquid mud plant. The whole liquid mud plant includes below items:

1) Totally Qty 75 × vertical storage tanks. The project request min. 400bbl usable capacity. GN Solids Control supplied 450 bbl vertical storage tank. Each storage is equipped with qty 2 mud gun and a level meter. Total usable capacity of the 75 vertical mud tanks is 33,750 bbl.

2) 2 packages of horizontal mixing tank unit. Each mixing tank is equipped with a dual mixing unit and dual transfer pump unit.

3) 1 package of horizontal processing tank C/W a shale shaker and qty 2 decanter centrifuge.

4) 6 packages of centrifugal pump transfer unit with its motor starter.

All pipelines and electrical control system are supplier by GN Solids Control. This year, GN Solids Control will supply the rest qty 61 vertical storage tanks, 1 package of mixing tank unit and 1 package of processing tank unit.

ViST is Vacuum Shaker Screen Technology which is developed and designed by GN Solids Control. The shaker screen vacuum unit is to work with shale shaker to reduce drilling waste and recycle drilling fluids. At some jobsites, clients use screen vacuum unit to replace drilling waste high G drying shaker.

There are insert type screen vacuum unit and external mounting type screen vacuum unit. For GN own design shale shaker and some other shaker model which use frame screens, if there is space to insert the catch pan (tray) under the outside discharge end shaker screen, we call it insert type screen vacuum unit. It is relative small modification on job site shale shaker. If for GN brand shale shaker, all shaker models reserve the design to add screen vacuum unit directly.

For insert type vacuum screen unit, the catch pan is fixed directly under the discharge side shaker screen. The screen API size depends on the shale shaker API screen, or the high G drying shaker API screen.

But for the external type screen vacuum unit, the client will use a small screen after the shale shaker or high G drying shaker.
Some clients want to use very fine screens, like API-230,270 and 325 while they add the external screen vacuum units to the shale shakers on offshore drilling rig mud system.

GN Solids Control does not recommend clients to choose such fine screens for external screen vacuum unit after solids control shale shaker. As solids control shale shaker does not use very fine screens. The high G drying shale shaker may use fine screens. But API 230, API 270 and API 325 are not used by solids control shale shaker. The small screen API size should be similar to the shale shaker screen. It cannot be too fine. Otherwise, it may cause block.

In other job site while clients use the screen vacuum unit for GN shale shakers, the max. shaker screen API size they use is API 120 and API 140. Hardly over API 140.

In April, a full set of drilling cuttings washing system is ready for commissioning for a China client at client’s job site. The drilling cuttings washing system is used to wash and separate oil base drilling cuttings and oil sludge generated from oil and gas drilling, and refinery.

There are 7 treatment modular in this drill cuttings treatment washing system:
1.Pre-treatment: A set of coarse shale shaker is used in this modular for crushing the big rocks and for pre-seperation. It is the pre-treatment before all separation steps.
2.Screening separation modular. There is a high G drying shale shaker used in this step to remove the big size particles.
3.Washing modular with static mixing for mixing and preparing solids and liquid mixture. After that, the liquid mixture can be separated by next step separation equipment.
4.Liquid and Solids separation modular with decanter centrifuge for 2-phase separation. It is the 1st time liquid and solids separation.
5.The 2nd time washing modular with dewatering treatment to remove the fine solids in the liquid.
6.The 2nd time 2-phase decanter centrifuge separation unit for ultra fine solids separation.
7.The liquid recovery modular.

It is a a full function oil based drilling cuttings washing and separation system with a full set of separation and treatment equipment. Below list is the major treatment equipment used in this oil based drill cuttings washing system:
1.A Drum shale shaker is used in the pre-treatment unit to crush the big rocks and remove it.
2.A high G drying shale shaker is used in the screening separation modular to remove the big size particles. It is the most hot sale shaker model GNZS594F which is widely used in oil and gas drilling solids control systems.
3.2 sets of static mixing unit are used in the 2 stage washing modular.
4.A inclined plate clarify is used for soil settle down in the oily liquid, which is discharged from decanter centrifuges.
5.Screw conveyor and belt drive conveyor are used in the system to feed for shaker and for solids discharge from decanter centrifuges and shale shakers.

Chinese Lunar New Year holiday is coming in Feb. There weeks, all workshops of GN Solids Control are works with more shifts in order to finish all orders before the big holiday. A full package drilling mud solids control system will be ready soon and dispatch to sea port next week to catch the vessel.

The full package solid control system is designed and made for a European client. The client cooperated with GN Solids Control for many years. It is not the 1rst mud system the clients bought from GN. They have many similar size drilling mud system from GN Solids Control.

Below is the major equipment list of the full package drilling mud solids control system:

1) Shale Shaker. It is the 1rst stage solids control equipment for drilling mud system, and it is the major separation equipment in a drilling mud treatment system. There are 2 sets linear motion shale shaker in the mud system. Some clients will order an extra shale shaker as backup. The shale shaker model is GNZS594F. It is a 4-panel shale shaker. And it is the most hot sale shaker model from GN Solids Control.

2) Mud cleaner. It is normally 1 mud cleaner in a full package mud cleaning system. And in some jobsite, clients will use more shale shaker to replace mud cleaner. It is also called as 3-in-1 cleaner. It is the combination of a shale shaker, desander separator and desilter separator.

3) Lower/middle speed Decanter centrifuge. The model is GNLW452D. It is a 18inch bowl size middle speed centrifuge which is used for barite recovering.

4) High speed decanter centrifuge. After low speed centrifuge, there is a high speed centrifuge GNLW363C in the system for fine solids separation. As after some circulations, there will be more and more ultra fine solids inside the drilling mud, the drilling mud is weighted. High speed centrifuge will be used in this condition to reduce the mud weight.

5) Centrifugal pump. There are 6 centrifugal pumps inside the system for different functions: a desander feed pump, a desilter feed pump, 2 mixing pumps, and supercharging pump for drilling rig mud pump.

A customized drilling mud processing system is is ready for shipment at GN Solids Control Beijing factory. It mud cleaning system is composted of a mud cleaner, a mixing hopper, and a centrifugal pump for mud mixing and transfer.
The drilling mud cleaning and mixing system is designed and made by client’s request to suit his drilling mud situation. Normally, mud cleaner is equipped after a pre-seperation shale shaker. But in this mud cleaning system, the first separation equipment is mud cleaner.

Drilling Mud Cleaner

Drilling Mud Cleaner

The reason why the client do not use shale shaker is that, they said the solids content in the mud is not much high. And mostly are fine solids. In this case, the drilling mud can be separated by mud cleaner directly. It is to save cost. As once the shale shaker is running, clients need to replace shaker screen periodically. It is a continue cost for operation. While delete the shale shaker, the system can meet client’s request. It can save the cost of shale shaker, and furthermore, the can reduce wearing spare parts shaker screen cost.

But if the solids content is high, or the particle side is big, which is over the hydracyclone separation point and its mud handing capacity, it is better to use a shale shaker before the mud cleaner. At one hand, the shale shaker can reduce the flow rate which feed to the mud cleaner. At another hand, after the shale shaker separation, the solids content will be reduced, and the big size particle are total removed based on the shaker screen API size and cut point. It can increase the hydraucyclone separation efficient, and also to avoid the fast wear out the hydraucyclones. 10 inch desander cone and 4 inch desilter cone are the most popular cyclone sizes used for drilling fluids separation system. Operator can choose the to use only desander cone or desilter cone, or both based on the mud condition and their budgetary. Desander and / or desilter cone quality depends on the handling capacity of the whole system.

Drilling Mud Centrifuge

Drilling Mud Centrifuge

Feeding pump for mud cleaner is centrifugal pump. The centrifugal feed pump is located on tank slope for compact design and for maximize the total tank usable volume.

After the mud recycling and mixing system, a drilling mud decanter centrifuge is used for fine solids separation. As there will be more and more fine and ultra fine solids after some circulation of the system. Decanter centrifuge will be used to reduce the mud weight.

The TBM construction and Pipe Jacking construction drilling will generate a lot of waste water slurry which contains big percentage of sand and stones. In order to accordance with environment protection regulations and save water, project operators have to separate the TBM drilling mud, to reduce the waste and reuse the water.

GN Solids Control can design and make full package of waste water slurry separation plants. The major separation equipment in GN slurry separation plant includes: shale shaker, desander, desilter, bottom drying shaker, etc… And there are accessory items for a one-stop turn-key solution: centrifugal pump for feeding desander / desilter mud cleaner, mud tank, electrical control system, etc.

The TBM construction and Pipe Jacking construction drilling are often took in urban areas, . In this case, the TBM drilling slurry separation usually requires compact design to suit for small working area.

1000GPM Mud Recycling Unit

A double deck shale shaker is used in the GNMS-1000D mud cleaning system. There are 2 sets of 10 inch desander cone assembly on top of the double deck shale shaker to use as a mud cleaner. The advantages of a single deck mud cleaner is that, it has the function of both shale shaker and cleaner and the footprint if small while with the compact design. The dirty mud will be fed to bottom shaker deck, which is mounted coarse shaker screen. The centrifugal pump is located on the tank slope to feed for the desander cleaner. Besides GNMS-1000D mud recycling system, GN Solids Control makes other capacity drilling mud cleaning system for trenchless drilling rigs: D Series Mud Recycling Models: 1) GNMS-200D mud cleaning system with handling Capacity: 200GPM, 50m3/h 2) GNMS-500D mud cleaning system with handling Capacity: 500GPM, 120m3/h 3) GNMS-1000D mud cleaning system with handling Capacity: 1000GPM, 240m3/h 4) Other models can be customized according to clients special request. GNLW452 is an economic standard decanter centrifuge. It is a 18 inch big bowl centrifuge. But the bowl diameter and bowl length ration is only 2. And the max. Bowl speed of the GNLW452 centrifuge is 2200RPM. It is a single motor decanter centrifuge with fixed speed control. VFD control is available if requested by clients. The centrifuge is widely used for trenchless drilling mud treatment, and oil & gas drilling mud barite recovery.

500GPM and 1000GPM are the most popular size drilling rig mud recycling system for Horizontal directional drilling, water well drilling, Coal bed methane drilling, and other trenchless drilling rigs.
500GPM mud recycling system is mostly a compact 1-tank system complete with separation equipment and mixing unit for compact design and easy movement.

Regarding 1000GPM mud system system, clients can choose 1-tank system or 2-tank system. 3-shaker mud recycling system and 4-shaker mud recycling system are the most popular proposal. 3-shake mud recycling system means 2 shale shakers plus a mud cleaner (3-1 mud cleaner, desander mud cleaner, or desilter mud cleaner).

Equipment list for 1000GPM mud system is normally as below:

1) At least 2 sets shale shaker. 4-panel or 3-panel shale shaker model are both fine. Single shale shaker model is min. 500GPM capacity. So for 2 shale shakers the handling capacity can reach to 1000GPM minimize.

2) 1 set of mud cleaner c/w shale shaker, desander and desilter, mud capacity is at least 1000GPM. It is the full functional and with compact design. As a 3-1 mud cleaner can save footprint. If clients want to reach a better separation performance, they can also choose a separate desander mud cleaner, or a desilter mud cleaner. Regarding the desander mud cleaner and desilter mud cleaner, clients can choose to equip with the same under flow shale shaker as the first stage shale shaker, or a mini size shale shaker with 2 screen panels. Clients can also choose a small desander or desander without shale shaker.

3) Feeding centrifugal pump for mud cleaner is 45kw or 55kw. The feeding pump can be located on tank skid or tank slope.

4) Mixing unit is C/W 6 inch mixing hopper. Mixing pump can be 45kw or 55kw. It is better to be the same model with mud cleaner feeding pump.

For 3-shaker system, all separation equipment and the mixing unit can be located on the same mud tank for company design. But if it is 4-shaker mud system, the first tank is recycling tank with separation equipment, the next tank is mixing tank.
