NESR provides filtration services to its clients to meet their requirements, save additional costs of well stimulation and avoid related operational problems due to non-filtered fluids, especially across the pay zone.
On a typical job, NESR would provide its two-stage, skid mounted, easy to handle filtration vessels. The primary and a secondary filtration stages are usually carried out together. In the primary filtration stage, the fluid is cleaned from debris and bigger solid particles using 200 to 50 Meshes. The primary stage reduces cost and time by saving the secondary stage cartridges from excessive plugging. As the fluid exits the primary stage it enters the secondary filtration stage where it is cleaned to the desired size of solid particles 20 to 2 micron cartridges. Size of mesh or cartridge is always discussed between NESR and client engineers for optimum results and cost-efficiency. Both meshes and cartridges could be replaced during the job whenever plugged. The number of sets required depends on the cleanliness of fluid and volume to be filtered.
NESR has filtered thousands of barrels on rig sites for reduced damage drilling as well as for UBD (Under Balanced Drilling) operations. The filtered fluid is stored in closed, clean frac tanks until it is used. NESR can also provide frac tanks and pumping units if necessary.
