An oil field shale shaker is a vital piece of equipment used in the oil and gas industry during the drilling process. It is a vibrating shaker screen that helps separate drilling cuttings, solids, and other debris from drilling fluids or mud. The shale shaker plays a crucial role in maintaining the drilling fluid’s properties and removing unwanted solids to ensure efficient and safe drilling operations.

The efficiency of an oil field shale shaker depends on several factors, including the shaker screen mesh size, vibration intensity, and the characteristics of the drilling fluid. Proper selection and maintenance of the shaker screens are crucial for achieving effective solids control and maximizing drilling fluid performance.

Overall, the shale shaker is an essential component of the drilling process in the oil and gas industry, helping to remove solids and maintain the quality of drilling fluids, which is vital for efficient and safe drilling operations.

Oil field shaker screens must be stocked indoors for several reasons. Firstly, storing them indoors protects them from exposure to harsh weather conditions such as rain, extreme temperatures, and direct sunlight, which can deteriorate the screens and reduce their effectiveness.

Secondly, indoor storage helps prevent contamination of the screens. Oil field operations involve various types of drilling fluids and chemicals, which can potentially damage the screens if they come into contact with them. Storing the screens indoors minimizes the risk of contamination and ensures their integrity.

Thirdly, indoor storage provides a controlled environment that helps maintain the quality and performance of the screens. Factors such as humidity, dust, and airborne particles can negatively impact the screens’ efficiency and lifespan. By keeping them indoors, these factors can be better regulated, prolonging the screens’ usability and effectiveness.

Overall, storing oil field shaker screens indoors is essential to preserve their quality, protect them from damage, and ensure optimal performance during oil field operations.

API RP 13C shale shaker screen for oilfield shale shaker

BY admin 18 March 2020 shale shaker, shale shaker screen

Shale shaker screen is the most important and necessary wearing spare parts for oilfield shale shaker and mud cleaner. The function of a shale shaker screen is to remove the particles bigger than the screen opening, and recover the usable drilling fluids which will go through the screen openings and get back to the drilling mud recycling system.

There are many brands shale shaker and mud cleaner, and every brand has his own design and own sizes shale shaker screens. In order to control the mud weight accurately, how do the mud engineers choose the right screens openings from different shale shaker and shale shaker screen suppliers?

In order to solve the problem, a general standard is necessary for design shale shaker screens. API RP 13C is an international popular standard to define the shale shaker screen specifications. A authorized lab will test a shaker screen by using a specific test procedure (as described in API RP 13C), the lab test will define a series of specifications of the screen, like D100 cut point, screen conductance, non-blanked area. After these specifications are confirmed, the API Screen Number is determined. It ensures that, all Shale shaker screens confirmed to API RP13C standard, if the API No. is the same, the screen cut point will be the same. Same model screens from different screen suppliers if with the same API NO., the screens are interchangeable.

Below definitions are some important parameters of shale shaker screens to help you know more about API screens:
API screen NO.: After testing a screen by using a specific test procedure (as described in API RP 13C), the API screen no. is determined.
Mesh: it relates to a piece of screen wirecloth, is a measure of the number of holes in a linear inch (such as 100 mesh) or in a linear inch in each direction (such as 100 x 60 mesh).
D100 Cut Point: The D100 cut point of a screen is the largest particle size which will pass through the screen opening. D100 means 100% percent separation.
Screen Conductance: It measured in kilodarcies per millimeter (kD/mm), defines a Newtonian fluid’s ability to flow through a unit area of screen in a laminar flow regime under prescribed test conditions. All other factors being equal the screen with the higher conductance number should process more flow.
Non-Blanked Area: The non-blanked area of a screen describes the net unblocked area in square feet (ft²) or square meters (m²) available to permit the passage of fluid.

GN Solids Control makes API RP13 shale shaker screens for different shaker brand. May you have any questions, welcome you contact GN Solids Control for inquire.

Mud De-sanding Unit will save a lot in Piling Project

BY admin 10 February 2017 Drilling Fluids shale shaker, Drilling mud system, HDD machinery, mud recycling, shale shaker, solids control, Solids Control Equipments

Vertical rotating drilling rig is the normal machine used in piling project. During the drilling process, in order to protect the inner wall of the drilling hole and speed up the process, the operator always chooses to use drilling mud. Then here comes another problem how to reduce cost of the drilling mud thereby to reduce the cost of drilling. The solution is to use mud recycling system to make the drilling mud reusable.
The purpose of the mud recycling system is to remove the large size solid particles in the drilling mud by several separation machines. In regards to the mud recycling system for piling project, it could be a very compact design as separation process is not so complex as that for oil gas drilling. GN solids control is one of the most experienced separation solution providers who could provide the mud recycling system for almost all the industries will use it. GN already developed the standard mud recycling system especially for the piling project.

De-sanding Unit

Strictly speaking, the mud recycling system used in piling should be called de-sanding unit as the drilling depth is normally shallow and most of the solid particles are sand. A de-sanding unit would be enough for processing the separation to get the expected reusable drilling mud.
GN’s de-sanding unit is a compact structure 2 steps separation system. The main equipment in this de-sanding
unit is combined with a 2 layers shaker and cyclone manifold. The double layers shaker is used for coarse solids separation by the under layers and the upper layer screen is for drying the slurry discharged from the cyclone unit. The tank under the shaker unit is used to store the drilling mud. One centrifugal pump is installed in the system for transferring the mud to the cyclone unit for sand separation.
This de-sanding unit could be connected with extra mud tank for larger capacity mud storage. The operators can also equip a jet mixing unit to make an self-contained mud recycling system for other drilling project like HDD and water drilling.

Different Tanks in the Mud Recycling System

Mud system will not work if there are no mud tanks. In the mud recycling system, the tanks are used to store the drilling mud to be a base where the solids control equipment to be installed. Normally, more than one mud tanks
will be used in the oil drilling mud system. For different purpose, the design of the mud tank is different, especially the inner structure of the mud tanks.
There are mainly 3 types of mud tanks recycling tank, intermediate tank and premixing tank. Then what are the different among these 3 types of mud tank?
The recycling tank is where to install the primary shakers and degasser unit, and also the de-sanding and de-silting unit. Each of equipment needs a compartment in the mud tank. As the recycled drilling mud is treated by the solids control equipment one by one. After treatment by each of the equipment, the drilling fluids will be cleaner than before. Thus the drilling fluids cannot be mixed. The wall between two compartments always has an overflow port for balance of the drilling mud in the tank.

Mud Tank System

For the tank to install the de-sander and de-silter unit, inner structure of the mud tank would be much complex as there are pipes for centrifugal pump to such the drilling fluids from inside of the tank and transfer to the cyclone for further treatment. Operator has to know which pipe is for de-sander and which pipe is the desilter.
On the mud tanks for installing the solids control equipment on, there always have the walkways and handrails. The walkways provide enough space for the operator to walk around the equipment for operation and maintenance. Intermediate tank is a type buffering tank, part of this tank is for mud recycling, and other parts are used for mud storage. Operators can easily tell how many compartment in this tank.
The premixing tank is used to mix drilling fluids. It always is connected with the jet mixer unit. The mixing pumps suck liquid from mud tank and send liquid back again with added mud materials from the hopper. Thus the pump should be able to suck the drilling mud from anywhere in the mud tank used for mixing and storage.
Therefore, in the mixing tank, there are two groups of pipelines, one for sucking, and the other one is for sending liquid back. Mug agitators and mud guns are always installed on the mixing tank.
Though, the inner structure of the above tanks is different, the outer dimension and design are always the same for purpose of easy transportation and assembling.

How the Double-Layers Shale Shaker Works for Mud Recycling

BY admin 28 November 2016 mud recycling, shale shaker, solids control, Solids Control Equipments

Shale shaker is very common equipment used in the drilling mud recycling system. Its function is the first stage for remove the coarse solids in the drilling mud. Sometimes, we may see the double layers shale shakers are installed in the mud system. Below we would like to share some information on how the double layers shale shaker works in the mud recycling system.
Some mud system may has limitation on the footprint, thus, the operators would like to equip a shale shaker with high treating capacity but compact structure. The double layer shaker no doubt is the ideal choice.

Shale Shaker

For shale shaker application – when the unit is used as primary shale shaker, it is located at the very beginning of the mud system. As we know, the shale shaker unit has buffer box for mud feeding into the shaker unit. The mud overflow out from the buffer box would flow into the upper shaker screen panels with coarse screen for larger size solids separation. The lower screen panels would be much finer for small solids separation. Double layer shale shaker will have a relative larger capacity; in the meanwhile, it can remove out smaller
solids.
For Mud Cleaner application – Shale shaker can also be used as underflow drying shaker by combining with hydro cyclone unit. This type mud cleaner functioned as both shale shaker and cyclone unit. The lower screen with coarse mesh is for larger solids separation, and the upper screen with fine mesh is for drying the slurry discharged from the cyclone.
GN now has main two models of double layers shale shaker. One is coming from the shaker model of GNZS703. Its deformation GNZS706 double layer is for larger capacity shaker and GNZS705 for mud cleaner unit. The other is GNZS752; it can be upgraded to GNZS753 double layers. These double layer shale shakers are widely used in GN’s compact design mud recycling/de-sanding unit for area limitation project.

One Machine Does Jobs as both Shaker and Mud Cleaner

BY admin 27 June 2016 Drilling Fluids shale shaker, Drilling mud system, mud recycling, shale shaker, shale shaker screen, solids control, Solids Control Equipments

The persons who know solids control equipment may know well on the shale shaker and mud cleaner unit. These 2 machines are very common in solids control system that do solids separation job from the first to forth stage. The shale shaker is located at the very beginning of the mud recycling system for primary solids control; the coarse cuttings could be removed by the shale shaker. While after treated by the shale shaker, the drilling fluids would be transferred to the mud cleaner for further treatment.
For the purpose of easy maintenance, in the same solids control system, the mud cleaner is equipped with under drying shaker that is same model as the primary shale shaker. Mud cleaner is just a machine on which the cyclone frame was fixed above. The mud cleaner unit is only able to be used to separate the solids via the hydrocyclone units. Why the mud cleaner unit cannot be used as a shale shaker even if it has the under drying shaker? This is really a good question. GN’s engineer equipped a logging tank to the mud cleaner unit and the mud cleaner unit becomes a shale and mud cleaner composition unit.

GN Shaker & Mud Cleaner Composition Unit

Normally, GN’s shaker unit has back type logging tank that is used to collect the drilling fluids coming out from the drilling hole. The drilling fluids accumulated in the logging box firstly and then overflow into the shaker deck, thus the shaker screen will not be damaged by the high pressure drilling fluids. This unit could be used as a shale shaker unit.
De-sanding and de-silting cyclone are installed on the mud cleaner for finer solids separation. The solid discharged out from the bottom nozzle of the cyclone also has high pressure that will shorten the screen life if directly dropped onto the screen surface. To avoid this situation, there is a hopper collection box that is used as buffer between the cyclone and screen. To make this machine compact, GN’s engineer designed to insert the buffer box into the logging box, which means the logging box is also used as second buffer box for the cyclone unit. This is the function of mud cleaner.
One thing need to be noted is this shaker and cleaner machine can only be used for one function one time: either shaker or mud cleaner. This is a cost saving unit with small footprint, for some project not very urgent, this unit could be a very ideal choice. GN ever showed this unit at Beijing CIPPE, much attention was attracted there.
