Liquid Mud Plant Provided by GN Solids Control

Liquid mud plant is also called LMP, which is used for preparing, storage and treatment of the drilling mud. In a complete liquid mud plant, there should be 3 mainly drilling mud tanks for different purpose:

1. Mixing Tank.

Mixing tanks are always cuboid shaped mud tanks equipped by mud mixing hoppers. Those hoppers are always Venturi hoppers linked to centrifugal pumps. When pump is sucking mud from one compartment to another, and when mud is passing the Venturi hopper, there will be a sucking force to suck in the chemicals from the hopper.
Mixing tanks have mud agitators and mud guns, too, for stirring up the mud in order to prevent settling down. Meanwhile, there are also pumps for transferring the prepared mud from mixing tank to others.

2. Treating tanks.

When used mud is delivered to the liquid mud plant, the dirty mud shall be treated by separation equipment in order to remove the particles and to be returned to the storage tanks. The separation equipment are mainly shale shakers and decanter centrifuges, and when there are extra fine particles, there should be chemical dosing for flocculating.

3. Storage tanks.

Storage tanks are not complicated in pipelines and always using single guardrails. There are no divided compartments inside a storage tank and the most commonly used equipment are mud agitators and mud guns. Both mud agitators and mud guns are used continuously for stirring the drilling mud from being settled down to the tank bottom. Clean mud will be safely storage in those tanks.

GN Solids Control has 2 kinds of storage tanks available, the cuboid shaped ones and the cylinderic ones, each type has its own advantages.

1500GPM Drilling Mud Cleaner for Drilling Company in China

In a drilling rig solids control system, there are at least 3 steps for separation, the shale shaker, the desander cones and desilter cones. And there is a machine as a combination of desander and desilter, which is called a mud cleaner. Comparing with such designs as a single desander plus a single desilter, the mud cleaner occupies a much smaller footprint. Meanwhile, by sharing one drying shaker, the mud cleaner is less power consumable.

Just 2 weeks ago, GN Solids Control has provided to a drilling company in China with 3 sets of mud cleaners, with same model GNZJ594F-3S16N. Each mud cleaner of this model can serve a 1500GPM treating capacity, which is suitable for a large horsepower drilling rig. So the totally 3 mud cleaners are quite probably to be allocated to 3 drilling solids control systems.

Main Specifications of GNZJ594F-3S16N:

1. GNZJ594F: it is a shaker model among GN shale shakers, it is equipped by 2 vibrating motors each of 1.72kw power. The shaker is equipped by 4 pieces of shaker screens, with a total screen area of 2.73 square meters. The shaker deck is quite strong and uses good sealing in order to prevent leakage. The shaker deck angle can be adjusted during operating for achieving a good performance.

2. Shaker screens. The shaker screens on the shale shakers are made by GN Solids Control, too. GN shale shakers are fully in compliance with API RP 13C, with same screen dimension, the non-blanked area and conductance are both comparably larger.

3. Desander and desilters. GN chooses polyurethane desander and desilter cyclones for longer service life. Desander cyclones are of 10 inch diameter for the 40 microns cutting point, and desilter cyclones are of 4 inch diameter for 20 micron cutting point.

For different jobsite conditions, GN has other optional mud cleaner models. Please contact GN sales team for more information.

As leading manufacturer for drilling mud solids control and drilling sludge treatment equipment and a professional solution provider, GN Solids Control has designed and put into reality a complete system for both mud recovery and slurry treatment which is suitable for for mud preparation, mud recovery and clarification, mud weight control, mud storage until slurry treatment in horizontal drilling and pipe jacking industries. This system is combined by following components:

1. Mud tanks: This systme is equipped by several mud tank skids with effective tank volume≥25m³. They are suitable for transportatiaon inside containers and being lifted at jobsite.

2. Shale shakers. A single shale shaker’s designed capacity is larger than 120m³/h, with vibrating motors with total power 3.44KW. Each system has 2 or 3 shale shakers depended by the requested capacity. The shakers are well sealed and easy for changing screens and spare parts. During transportation, the shakers are to be removed from tank and to be shipped inside container.

3. Mud cleaner: Mud cleaner is a combination of both desander and desilter. The capacity of desander and desilter are in complianc with the total system’s request and achieved by certain quantity of cyclones. Both desander and desilter share the same drying screen on below, with screen area of 2.63 square meters. Total power 3.44kw.
4. Decanter centrifuge: there is a big bowl decanter centrifuge located after the desilter cones. The cutting point of decanter centrifuge is 2 to 5 microns, which is suitable for remove the fine particles from the drilling mud. In this system, there are big bowl centrifuges adopted, with 18 or 22 inch bowl diameter.

5. Chemical dosing system: in case there are extra fine particles in the drilling mud, we have to invite a chemical dosing system with polymer injected into the drilling fluids in order to flocculate the extra particles to be within the centrifuge’s treating range. The chemical dosing system is designed inside a 20 ft container for easy transportation and layout.

6. Jet mud mixing unit: a jet mud mixing unit is used in this system for prepare new mud by adding drilling chemicals into the clarified driling mud.

Drilling Fluids Shale Shaker and Mud tank for Offshore Drilling Company

As the crude oil price is increasing stably, the numbers of active drilling rigs is on a rise, too. Among which, quite a lot are offshore rigs working on offshore platforms. Under the oceans, the crude oil reservation is remarkable, and lots of oil companies are joining to the offshore drilling industry. In order to take into consideration of environment protection purpose while drilling, the drilling mud shall be treated in time and to leave the waste to the least.
GN Solids Control has been providing offshore drilling companies for years with the high quality and compact designed mud recycling system. Here is information of a recent project:

1. In this project, the main equipment is shale shaker. Shale shakers are most important for a drilling mud system, which remove most solids particles from the recycled drilling mud. GN has different models of shale shakers, from the mini shale shaker with 2 pcs of screens to the double deck shale shaker with 2 layers holding 6 pcs of shaker screens. Each shale shaker is equipped with 2 vibrating motors, with total power less than 4kw. And the feeding for shale shaker is easy cause the mud flows directly from drilling. There is even no need for an extra pump.

2. Mud tanks are another main component for this system. They are used to receive the clean mud for next cycling. By using the jet mud mixer along with the tanks, the new chemicals can be added into the mud system.
It is clear that there are no desander or desilter cones in this system, for one thing, comparing with shale shakers, the desanding or desilter cyclones are less efficient. For the other, both desander and desilter cones need large power centrifugal pumps for feeding.

In this case, the client can collect the drilling solids waste to a vertical cuttings dryer or decanter centrifuge for drying before discharge. And also the drilling fluids can be retreated by decanter centrifuge when there are fine particles in the fluids after several cycles.

How to Choose Suitable Mud Tank Volume for Diamond Core Drilling and Geothermal Drillings

As is common sense for all kinds of drillings: 1, Drilling mud should be invited into drilling procedure, 2. The drilling mud should be treated after the drilling procedure, considering both economy reason and environment protection.
Well, do you know how to choose a suitable tank volume for such diamond core drilling and geothermal drillings? Here we have some tips and useful sequences to follow:

1. The required mud flow should be determined according to the drilling structure and drilling tool type;
2. Select the appropriate mud pump for the core drilling or geothermal drilling rigs.
3. Fully take consideration of required drilling rate and the time needed to prepare the mud.
4. Take into consideration of the solids control system (the mud separation equipment)’s recycling speed, including the rock powder carrying rate. This factor does affect the needed mud tank volume quite a lot.
5. Also consider the normal circulating mud volume, cross slurry distribution capacity and reserve mud capacity;
6. On the premise of meeting all above mentioned factors, try to select a smaller reserve coefficient, in order to reduce the amount of mud, which will also reduce the treatment capacity of waste mud.

What solids control equipment is always needed in such drilling projects?
A diamond core boring or geothermal drilling always need a comparably smaller mud recycling system comparing with other drilling like oil and gas or even HDD. Such mud systems are always more compact, with only necessary and efficient equipment.
A shale shaker is a must, cause shale shaker always removes the most solids from the drilling cuttings. In order to save space without sacrificing separating capacity, operators prefer to use a double deck shale shaker at this stage. And after the shale shaker, there should be a desilter and a decanter centrifuge, among which, the desilter is optional while centrifuge is preferred.

Drilling Rig Solids Control Equipment shippped to Oilfield Service Company

Solids Control systems and equipment are quite important for a successful drilling project. An efficient solids control system can helps to remove solids particles out of the drilling mud. In this way, the expensive drilling mud could be reused in future drilling. What is included in a complete solids control system?

A complete solids control system, especially for a large power horse drilling rig, should have following equipment divided per tanks:

1. The trip tank. Per certain rig size, there should be a certain amount of drilling mud to be prepared, but during drilling, there is always some mud loss because of drilling or because of mud separation. So there should be a trip tank holding well prepared mud for compensate the mud loss. For the trip tank, there is always a mud agitator and a centrifugal pump as trip pump.

2. Settle tank or also called the shaker tank. Shale shakers are the first step separation of the solids control system, they are used to remove the most solids from the drilling mud with suitable vibrating G force and screen mesh. On a long shaker tank, after the shale shakers, there should be a degasser to remove the bubbles generated during drilling to ensure the safety and to protect the pumps in following steps. If there is a mud cleaner in this system, it should be on this tank, too. A mud cleaner is a combination of desanding cones and desilter cones fed by centrifugal pumps.

3. Active tank. It is a tank for decanter centrifuge. The decanter centrifuge is located after the mud cleaner, to do the barite recovery or fine particle separation. It is always fed by a submersible slurry pump or a screw pump

4. Suction tank for mixing and reserve tank for storage.
