Screen mesh size here means the API number of shaker screen. It is a range of screen filtration cut point. During the certain range at certain drilling phase the shaker request different mesh size.

Screen mesh size popular at AIPU Solids

Popular screen mesh size is ranged from API 100 to API 170. Then API 80, API 60, API 230, API 270, API325. As we know the shale shaker is the first phase solids control equipment to get rid of cuttings larger than 75 microns. However, according to actual drilling practice the screens on shaker mostly used API 100 to API 170.

Then the screens on mud cleaner are finer from API 200 to API 325. Compared to screen on shale shaker, the screens on mud cleaner last longer since the less particles and finer cuttings. That means the loading for mud cleaner screen is less.

Screen mesh size

Among the screens delivered, the popular mesh size API 100-170 are at rate of 70%. Some clients even only purchase screen sized API 140, and API 170.

Difference between shaker screen and wire cloth mesh

We know the shaker screen is made from wire cloth or wire mesh. So, some clients think the shaker screen mesh size is same with wire mesh size. Actually, they are different

For almost shaker screens, we use 2-3 layers wiremesh to configure the screen panel. That means the general cut point and separation range will vary from the single layer wire cloth. And the mesh size is not the API size. As we know the API size means a certain range of separation point under D100 designation according to API RP13C or the ISO13501.

So, the difference including cut point and the penetration or conductance. Single layer wire cloth just tell us this cloth mesh size and the approximate opening size. As we know it is related with the wire diameter, too.

How to order proper mesh size screen?

Please consider to consult the mud engineer as the first option. If there is no engineer available, please tell us your working condition. Including but not limited to the drilling condition, mud property, the flow rate you need, the shaker information, the discharge result you prefer. Such as you need drier material and so on.

Based on above information or data, we can get a proper solution for you. Just contact us freely if you have any demand or question on screen mesh size

Shaker screen size we talked here means the mesh size or API size of the screen panel. What is the proposal on screen size during the whole drilling?

Shaker screen size mostly used during drilling

We know different drilling section will use different size screen. Usually, the oil well drilling will be three sections. At each section, we will select certain screen per actual drilling condition

Take one well of our clients as an example. The first section, they use API 80 and API 100 shaker screen on their FLC514 shaker. While the second section, they use API 200, and API 230

Shaker screen size

For the final part-third section, they use API 120 and API 170 screens. The different screens are fit together at the same time. That means, 4 panels screen including 2 different mesh size

Why we use different size screen?

Different drilling condition and mud property will generate different cuttings and fluids variation. If the drilling fluids is too much with large quantity cuttings and gravity, we may need the coarser screen at the beginning. Also, we need to change deck angle

Another client sent us information of screen size as below:

1. Three sets shale shaker connected with one flow divider as a triple tandem shaker
2. The first shaker was fit with 2 panels API 120 and API 140 screen
3. The second shaker was fit with 2 panels API 120 and API 170 screen
4. The third shaker was fit with 4 panels API 100 screen

This configuration is for their well at section 6 1/8".  And the cuttings generated are sand and silt. After test by mud engineer, the drilling fluid maintained good property and reflected no much lost. So we change screen size at different section is to get effective drilling and competitive cost

Special shaker screens

What are the popular shaker screens size?

Although there are many many different shaker and shaker screens. The popular screen panels are almost same. API 80, API 100, API 140, API 170, API 200, API 270.

No matter you operate Derrick shaker, or SWACO Mongoose, or the VSM300 from NOV Brandt.

According to our previous record, the most popular screen size are API 140 and API 170. What else are you interested in? Please come to AIPU for any question
