CMS is one type of shrouded metal mesh screen. It is a patent product of COSL. The unique  structure jacket can hold sand and maintain good flow-throng capability. CMS can be employed  in most reservoirs which needed sand control.

◎ Two layers 316L stainless steel filter media, high reliability and good anti-damaging performance; 

◎ Drainage layer between the filter media layers improves the flow properties; 

◎ High permeability and porosity, large open area;

◎ Easy to run in the long horizontal wells; 

◎ Anti-acid and alkaline, anti-high temperature, long service life;

◎ Simple construction, easy for operation, benefits to lower the completion costs, and increase the  rate of success in installation; 

◎ Remaining sand control performance even the radial deformation up to 40%; 

◎ Aperture size of CMS screen usually ranges from 60μm to 500μm.

APPLICATIONS

◎ RReservoir with d10/d95 ≤ 10 & d40/d90 ≤ 5 & sub44μm ≤ 5%; 

◎ Stand-alone, open hole especially, gravel pack and frac-pack application also; 

◎ High production rate well with electric submerged pump; 

◎ High temperature high pressure well and corrosive well; 

◎ Overhaul completion and thermal stimulation wells.

Note: 1. On the basis of different accuracy, the inside and outside diameter of the sieve tube  changes slightly, and the accuracy is calculated at 120 μm. 2. Material, buckle, pipe specification, precision can be customized according to customer  requirements.
