Abstract
When screens are used as the sole means of sand control, they function as a downhole filter. The entry of sand or other particles into horizontal and vertical wells presents the problem of steel erosion and productivity lost. Downhole is the most desirable location to restrict its access into the well. The problem of material reliability testing is relevant today, that’s why several erosion tests were made and studied. Self-made test bench allow varying velocity flow and fractions conditions (composition, quantity, size, hardness). Slurry erosion experiments resulted in wear of downhole sand control screens. The wear criteria were checked by weight loss of screen samples material and its integrity degradation. The idea of slurry erosion tests was to reveal screens wear.

Summary
Petroleum production connected with the specific conditions of equipment operation: high temperature and pressure, corrosion and erosion of the downhole material, friction and wear of drill and casing pipes and so on. Erosive wear is one of a major concern in oil industry [1], and downhole screen slurry erosion, in particular, has increased in importance with the development of its complexity and cost. According to [2] sand is commonly produced along with production oil, and this is a problem for the industry. Steel reliability testing is relevant today for estimation of essential safe mode operating conditions, and because of the need to know under which of them breakages and failures of the equipment, caused by continual use in hard circumstances, will come and interface to economic loss
