So, let’s get started on your journey to finding the ultimate shaker screen for your oil and gas industry needs!

Choosing the right shaker screen is crucial for the success of your drilling operations. A shaker screen is an essential component of the shale shaker, which is responsible for separating solids from drilling fluid. Solids control is vital in the oil and gas industry as it helps maintain drilling fluid properties, prevents equipment damage, and ensures the safety of personnel.

The right shaker screen can improve solids control efficiency, reduce waste disposal costs, and minimize downtime. It can also enhance the overall drilling process by improving drilling fluid quality, reducing wear and tear on other equipment, and increasing drilling productivity. Therefore, investing time and effort into selecting the best shaker screen is a wise decision.

When choosing a shaker screen, several factors should be taken into consideration to ensure optimal performance. One crucial factor is the screen’s mesh size, which refers to the number of openings per linear inch. Mesh sizes typically range from 20 to 325, with lower numbers representing coarser screens and higher numbers indicating finer screens.

Another important consideration is the material used to construct the screen. Common materials include stainless steel, composite, and polyurethane. Stainless steel screens are durable and resistant to corrosion, making them suitable for harsh drilling conditions. Composite screens offer a balance between durability and cost-effectiveness, while polyurethane screens are known for their flexibility and longer lifespan.

Flow capacity is another critical factor to consider. The screen’s flow capacity determines how efficiently it can process drilling fluid and separate solids. It is essential to choose a shaker screen with adequate flow capacity to prevent bottlenecks and maintain optimal drilling operations.

There are different types of shaker screens available in the market, each with its own advantages and disadvantages. The most common types include flat screens, pyramid screens, and hook strip screens.

Flat screens, also known as conventional screens, are the most basic type of shaker screen. They have a simple flat surface and are suitable for general-purpose applications. Flat screens are easy to install and maintain, but they may have limited solids control efficiency compared to other types.

Pyramid screens, on the other hand, have a pyramid-shaped surface with larger openings at the top and smaller openings at the bottom. This design allows for improved solids control efficiency and increased flow capacity. However, pyramid screens can be more expensive than flat screens and may require more frequent replacement.

Hook strip screens are another popular option, characterized by a hook-shaped strip that holds the screen in place. These screens are known for their easy installation and removal, making maintenance and replacement quick and hassle-free. However, hook strip screens may have lower flow capacity compared to other types and may not be suitable for high-volume drilling operations.

Mesh size plays a crucial role in determining the performance of a shaker screen. The choice of mesh size depends on the desired cut point, which refers to the size of the particles that the screen can effectively separate.

Finer mesh sizes, such as 200 or 325, are suitable for removing smaller particles, while coarser mesh sizes, such as 20 or 40, are better at removing larger particles. It is important to select the appropriate mesh size based on the expected particle size distribution in the drilling fluid.

Using the wrong mesh size can result in poor solids control efficiency, increased screen wear, and reduced flow capacity. It is recommended to perform regular particle size analysis to determine the optimal mesh size for your specific drilling conditions.

Before selecting a shaker screen, it is advisable to test and evaluate different options to determine their suitability for your drilling operations. Testing can be done in a laboratory or on-site using a test rig. The test rig simulates the actual drilling conditions and allows for accurate assessment of the screen’s performance.

During testing, parameters such as screen conductance, cut point, and solids removal efficiency are measured and analyzed. Conductance refers to the ability of the screen to allow drilling fluid to flow through it, while cut point indicates the particle size at which the screen can effectively separate solids. Solids removal efficiency measures the screen’s ability to remove solids from the drilling fluid.

By conducting thorough testing and evaluation, you can make an informed decision and select the shaker screen that best meets your specific requirements.

Proper maintenance and cleaning are essential for extending the lifespan of your shaker screens and ensuring consistent performance. Regular inspection of the screens is necessary to identify any signs of wear or damage. If a screen is found to be damaged or worn out, it should be replaced promptly to prevent further deterioration.

Cleaning the screens after each use is also crucial to remove any solids or debris that may have accumulated. This can be done using a pressure washer or by soaking the screens in a cleaning solution. It is important to follow the manufacturer’s guidelines for cleaning and avoid using harsh chemicals that can damage the screen.

Additionally, proper storage of the screens when not in use is important to prevent deformation or damage. Screens should be stored in a clean and dry environment, away from direct sunlight and extreme temperatures.

Cost is an important factor to consider when selecting a shaker screen. The initial purchase cost, as well as the maintenance and replacement costs, should be taken into account. While it may be tempting to opt for the cheapest option, it is important to balance cost with performance and durability.

Cheaper screens may have a shorter lifespan and require more frequent replacement, resulting in higher long-term costs. On the other hand, investing in higher-quality screens may initially be more expensive but can save money in the long run by reducing downtime and replacement frequency.

It is advisable to consult with suppliers and manufacturers to obtain cost estimates and compare the total cost of ownership for different screen options. Taking into consideration factors such as screen lifespan, maintenance requirements, and solids control efficiency will help you make an informed decision based on both performance and cost-effectiveness.

Shaker screen life is usually considered as an important issue. Then how long should a high quality shaker screen last during operation? Is there any standard or tips? How can we get screen lasted longer? Please find following information for your reference.

How long is usable life of shaker screens in common well drilling?

Screen usable life is a really comprehensive question but often asked by clients. There are so many different issues affect its life. Including screen itself quality, operator professional level, mud condition or working condition, shaker condition, handling way, cleaning and maintenance on screen, storage condition, and so on. These are factors from buyer or user.

As per present information we get the screen life of different models or brands is from 20 hours to 22 days. This data including many different pattern of screen, different API size screen, different working condition. How should we consider this ask reasonably? Make records and test regularly during well drilling. Such as drilling condition, mud property, filtration result, screen life, and so on. Compare screens last differently under same condition then find out the better screen. If we select screens improperly even they last over 30 days that makes no sense. We have some feedback from our users under a certain condition with their satisfaction. Please check below feedback:

There are also oral feedback from many other users, but without sufficient reference information. Please find our suggestions or recommendation on enhancing screen life during oil drilling:

• Keep the screens clean
• Storage of used screen should be on racks if they are to be reused.
• Screens for reuse should be marked with previous hours run so that screen TOTAL life is known.
• Maintain a proper beach at end point on the screen. The screen should be kept 75-85% flooded inside the shaker. Too much beach leads to screens being abraded by dry cuttings and premature wear can occur
• Before drilling commences inspect all shakers condition, such as compression status, tension fingers,mounting rubbers, channel rubbers, side plates coating, jack, and motor voltages, deck angle, etc.
• Check motion of shakersand G force if possible.
• Clean off dry cake build-up from the motors
• Look for any leaks around the header tank and sump
• If flow rate is high keep bed inclination at higher degree preferably 4-degree to ensure proper pool vs beach ratio. As soon as flow rate is stable (reduced) reduce bed inclination preferably at 2 to 3-degree.
• On Top hole drilling run less fine screens such as API 60 or 80 to avoid premature degradation of the screens

How long is the recommended shelf life for screens?

Depending on screen types. For example, if the screen is frame type without rubber strip backside nor rubber sealing on sides, we can store it on shelf for 2-3 years. But the storage condition is away from extreme weather and moisture. Why? We know screen panels including frame and S.S screen cloth. The frame is a steel frame (coated) or composite frame. There are elements that will age and this affects screen life & performance. For screens fit with rubber strip or sealing rubber, the suggested shelf life is no longer than 12 months. As we know, the rubber material is easy to age even under common storage condition. For all screens, when we keep them in a warehouse please consider below suggestions

1. Clean them after every working shift
2. Keep screens packed in cartons and even in plywood cases if possible
3. Keep the panels away from extreme weather, especially heat. Away from moisture, though there is coating and material is S.S
4. Stack them in order and mark panels clearly for convenient check and handle
5. Move screens gently, especially pay attention to screen surface to avoid damage by potential collision

Are all screens repairable?

How do we repair it? Why do we repair it? We use plugs to cover the broken area on screen panel. Usually, the plug is slightly larger than the hole of grids or damage area to make it tightly to the hole side. We repair screens consider 3 main reasons. One, repairing avoids further larger damage, two, repairing avoids mud loss, the other is repairing helps save cost to replace the screen with little worn. In some degree, repair screens enlong the shaker screen life.

We can’t repair all of screens. Presently, at Aipu Solids Control we provide repair plugs for flat screens made by us and for some typical famous brand shaker screen. Such as Cobra series screen, PWP48x30, PWP500, Mongoose series and so on. Furthermore, if we have made screens for you, they can be repaired with plugs produced by us, no matter it is a famous brand or not. To check if your screens are repairable please tell us the shape of a punched panel on the frame. Including shape, sides, the thickness of the sheet. Moreover, we need to confirm is it necessary to repair a screen panel. According to the worn area, or broken ratio. We suggest repairing the screen broken area is no more than 25%.
