Maximize performance under strong forces while maintaining flow

Schlumberger direct-wire-wrapped screens are made with a wire jacket shrink-wrapped directly to the basepipe. Screen components are welded to each other, but there is no welding between the screen and the basepipe, enabling the screen and basepipe to act as a single unit and ensuring that the tension, compression, and torque ratings of the screen are nearly the same as those of the basepipe. Basepipe perforations are designed to optimize flow while retaining strength.

Tech Paper New Analytical and Statistical Approach for Estimating and Analyzing Sand Production Through Plain Square-Mesh Screens During a Sand-Retention Test

There are two types of sand-retention tests (SRTs) generally used in the industry to evaluate the performance of sand-control screens for standalone-screen (SAS) applications—prepack tests and slurry tests. They represent complete hole collapse and gradual rock failure around the wellbore, respectively.
