Shaker screens life is the essential issue among quality. Shaker screen life affects consumption cost directly and the whole efficiency of drilling and time indirectly. What are the issues affecting the screen life and performance?

Shaker screens life

Simplified speaking, screen life is how long screen last during operation without any failure. For example, one of our user use our screens without any broken even cloth surface till to 350 hours that means the life is 350 hours

Actually, shaker screen life vary from each other. Same model screen with same API size in China and Kuwait may reflect different life time. And the same screen used in Singapore and USA may get different service life, too. Even the same screens all operated in one country or region, thanks to the different drilling condition, the life may vary from twenty hours to five hundred hours.

Why there is such a big difference? What are issues impacting screen life?

Issues affecting screen life

Based on same quality screen, same model and same size, what the objective factors may affect screen life?

1. The drilling mud property. Such as gravity,  viscosity
2. Shale shaker flow rate
3. Shaker condition or the compressing system condition
4. Operators expertise
5. Proper selection on mesh size
6. Proper shaker vibration strength

High-quality screen panel

Factors affecting screens performance

Besides shaker screens life, the performance is another important issue of screen quality. Many users find, even the screen last very long they lost much and the cost increased, too. Why is it like this?

1. The inaccurate mesh size operated and let useful material flow away
2. Improper mesh size selection lead screen blocked or mud lost
3. Shaker itself design problem
4. Vibration motor performance or specification
5. Some troubles on shaker. Such as tensioning system loosen
6. Deck angle need to be adjusted

Shaker screen life is critical issue reflects screen quality. For different well drilling, there are different drilling fluid also requests different mud process or treatment

Issues impacting shaker screen life

Screen itself quality, proper size selection, drilling mud property, legal operation and maintenance. Furthermore, the features of solids to be processed are impacting screen performance too.

If screen quality is poor, we may have to replace it within hours. Or we compare replacement with original one and the replacement ones may only last 1/4 time of genuine screen life. At the same drilling condition, same mud, same solid content or property.

Shaker screen life enhance

When we get high quality screen, but we use it improperly the screen life will be very short as poor quality ones. For example, we drill well deeps about 10000ft and 12 1/4" hole with large content shale and sand the proper screen should be API 170. If we select API 230 or more finer, the screens will be broken rapidly as the high abrasion on screen surface with fine wire screen.

Enhance screen life and performance

Understanding issues influencing screen life we will know better to en-long shaker screen life with higher performance. Select optimal size with proper configuration. Such as we need to process oil base mud or water base mud. Do we need rectangular hole configuration or square hole.

During operation, we have to check or test drilling mud on it's gravity, viscosity, solid content, and so on. Based on such datas we can verify if screen separation effective or not.

High quality PMD screen replacement

Every shaker off in a long time will request complete screen cleaning. And any panel screen removed should be cleaned thoroughly and properly. Thus we can use the screen panels time and time again.

Shaker operation when screen broken

Although we operated shaker, and screens legally per manual and the instruction we have to replace screen panel if there is broken or damage. Or we can repair screens instantly with repair plugs. If shaker screens are broken with large area, please replace them in time thus we'll have great performance on shaker.

Screen broken holes prevent high efficiency separation on cuttings. Thus the subsequent procedure will be not effective neither. So we need to check shakers and the shaker screen to make sure all is in good condition

We kindly suggest don't operate shaker with deep broken screen panel. Also pay attention on screen gasket under frame or back plate.

There are many details on shaker screen life enhance. Please refer to previous post or come to us freely. Some information is from practical operation in deed. But Aipu will give you optimal suggestion and solution based on your situation.

Shaker screens life is an important issue deciding the quality. Longer service life definitely give users more satisfaction and confidence also save direct cost. However, more and more practice proved screens longer life doesn't mean better quality or performance.

Our screens have been tested together with another supplier's screens. Their screens last a bit longer, but when the mud engineer test the mud below shaker they found the performance is very bad and then their screens were rejected.

Shaker screens life

Obviously, shaker screens life is how long can it last on a shale shaker. The same model/size shaker screens may reflect dramatically different life time if we use them under different working condition. Such as the drilling fluid property, the drilling depth, the geology, ambient temperature,etc. Of course, different operators and workers on shaker screen will lead different screen life as well. And the screen selection on at different drilling procedure will reflect rather different result

We ever sent same size shaker screens to 2 different client. They are corrugated shaker screen replacement for FLC504 series screen. Their mesh sizes are same, however, one user told us the usable life is 160 hours with satisfaction, the other user told us it can last over 400 hours. So much difference,ye? The difference came from the working condition.

Other performance of shaker screens

Besides shaker screens life there are still other performance/feature reflect screen quality. Such as the filtration efficient, conductance data, appearance and compliance, etc. High filtration efficient request as more open area as possible that means we should control the non-blanked area at min. level. The conductance data should be tested by professional unit under ISO or API standard to achieve standardized level. For the appearance, no doubt, utilize qualified raw materials and process them by advanced device also finish them with quality paint oil or polyster powder.

Shaker screen rubber seal is another issue affecting screens life. Some rubber strip can't bear long time in the oil based mud. Then rubber will pill off the shaker shaking come subsequently soon. Finally, shaker screen will be broken swiftly. Moreover, shaker screens without rubber seal will lead shaker performance worse than usual.

How we verify shaker screen life and performance

To verify a shaker screens life and performance we must understand complete working condition well. We have to know under same working condition which shaker screen can provide better quality and performance. Many users will take original screens as standard level, if under same operation condition we compare same type screens from different suppliers we'll find difference easily.

For example, we can put 3 panels 48x30 series flat screen replacement on original shaker. (Screens are API 200) Working condition is drilling depth about 4000m, core diameter about 156mm of Multiple lateral well. Lets suppose under such working condition original Derrick 48x30 series flat screen last 300 hours. Under same conditions, if replacement screen last 280~300 hours we decide it is ok. If it last only 40 hours, definitely it's bad quality

Based on above tips, we can select shaker screens at different prices and get related cost-efficient. If you need more information just come to us.
