I have a question if you can help
I am working at a crude oil processing plant
Recently we linked a new field to the plant but we got saturated of filters with rubber pieces, scales
Can we know the source of the rubber and how is it made?
thank you

It's hard to answer it.
Can you share more background info for the question, such as the details of the "new field", what's the rubber pieces look like, where was found, any pictures, etc.?

well;when i say new field we can say we connected new wells ( new feed added to the old one )
the rubber was found on strainer after getting them plugged
yo can get more details on the attached image

My first guess is deterioration of some rubber seals in the system.

we didn't suppose that because if it happen we can notice a failure on Somme part of the system and this didn't happen
all system parts are intact

So no downhole packers or other devices in these wells?
Once a packer is set I am not sure that failure of the seals would be noticed.

Probably rubber discs on the cleaning pigs used to commission the connecting pipeline may have torn off and got left behind in the pipeline. Then these rubber shards may have got swept into the CPP on startup?

if we suppose of theories of packers or rubber discs of pipelines so we are talking about limited quantity of rubber;
but in our case strainers are plugged frequently , that means a considerable quantity
my questions is rubber could be mad up in the bottom of wells under a high pressure and temperature ? just guessing any way

Have you done an analysis on the material? Have you identified the base polymer type?
If it is forming in the well it won't be a true rubber, it will likely be a wax of some type.
If you can identify it as type then maybe you can identify its origin.
Some rubber will breakdown in oil, swelling to over 4x its original volume and tearing itself apart in the process.

interesting!!
could i have a file or a video about how rubber will breakdown in oil, swelling to over 4x its original?
about the nature of rubber we sent a simple to have an idea if its synthetic or organic

In general when a rubber breaks down in an oil it either becomes mush or rock hard.
Rubber that breaks down in hot water is nearly always very hard.
