Field trial confirms downhole credentials of sand control system

wire wrap screen can be manufactured over them without interference. However, the purpose of the field trial was to test the valves under the most challenging well conditions possible, so the test assembly was built without a sand screen to filter out any of the solids. This exposed the system to the worst-case injection scenario for any


Ideally, you want to filter out 70% of the sand. Normal recommendations are 18-25 slot for fracture sand and 12 slot for formation sand. How do I determine the length ? Length is a critical factor in sand screen use. Most plugging occurs when the sand velocity. is too fast, causing sand to become wedged in the opening.

Optimization of Downhole Sand Screens by Lab Studies in

For SAS completions, proper screen selection is necessary as the screen is the retention media that allows production yet minimizes/eliminates sand production. In other words, the screen has to be fine enough to retain the formation sand, yet coarse enough to avoid production impairment due to mechanical skin or mud filter cake permeability damage.

Sand Control Screens Application and Selection

Sand screens are of importance in producing oil, natural gas and water which are often located deep underground. Large drills are used to bore below the surface of the earth to collect oil or gas. Then sand screen is inserted into the bore allowing natural oil, gases to come in while prevent sand out except very fine particles.

Water Well Maintenance and Rehabilitation

Corroded and enlarged well screen holes may lead to sand pumping, which in turn results in abrasive deterioration of pump parts and enlarged screen openings leading to excessive sediment velocities. In this case, abrasive materials carried in high velocity flows can lead to erosion of the screen openings.


Sand control screens—sophisticated screened pipe joints positioned in the wellbore directly opposite formation perforations—serve to block out sand while allowing the flow through of oil or water.

SAND CONTROL SOLUTIONS: Expandable sand screen alternative to

The techniques applied to control downhole sand production have not changed for many years. Almost every sand control solution involves the installation of a pipe-based filter that is either gravel packed or left as a "stand alone" screen.
