Paper presented at the SPE International Symposium and Exhibition on Formation Damage Control, February 10–12, 2010
Paper Number: SPE-128072-MS
... Abstract On of the major issues associated with quality assurance of woven metal mesh material for premium sand control screens is accurate and precise measurement of the micron rating. Standard tests for characterizing filter media are established by national authorities such as the British...

... the possibility of using the advantage of both mechanisms in a single device. The standard cut point test was used to determine the micron rating of different meshes in order to categorize them in different classes based on the average pore size. Different mesh weaves, namely Dutch twill, reversed Dutch twill...

... a well's production rate. Filters are often used to clean up fluids. Although two micron cotton filters are commonly used for this purpose, there are other types of filters and filtration systems available that could do a more efficient job for less cost. A study has been made of the efficiency and life...

... installation of multi-layer mesh screen Multi-layer mesh screen is the current state-of-the-art in premium mesh screen technology. It uses several layers of woven metal mesh filters of gradually decreasing micron rating and diffusion-bonded together, which creates a filter that provides better plugging...

... all the solids larger than their micron rating. Forinstance, a 2-mu m filter might be expected to remove all particles larger than2 mu m diameter. This is absolutely wrong! At best these filters can removeonly 90% of the solids from a fluid, and solids much larger than the filterrating pass through...

... on the vendor's numerical rating. While vendors typically provide a micron rating for their screens, this is a nominal micron rating and not a true micron rating ( Underdown, 1999 ). Bridging of the formation on the sand control media is highly influenced by the size and shape of the formation ( Fischer, 2014...
