SCHUMASOIL®

High Density Porous Polyethylene Well Screen

SCHUMASOIL®, a porous polyethylene well screen, minimizes flow resistance by providing a 35% - 45% porosity uniformly distributed along the entire length of the well screen.  Greater porosity, uniform pore distribution and predictable pore size provide the user with the ability to match flow characteristics of the well screen to that of the formation.  SCHUMASOIL® was developed specifically to solve characteristic problems associated with slotted screens.  The first of which is SCHUMASOIL’s ability to provide a seamless transition between the formation and an extraction or injection well system.  DSI has the ability to accurately produce a predictable homogeneous pore size well screen product, which is available in four different pore sizes providing the user with the ability to match flow characteristics of the well screen to the surrounding formation.  In addition to the four (4) pore sizes, SCHUMASOIL is available in four (4) pipe size diameters which are 1, 2, 4, and 6 inch.

The selection of SCHUMASOIL® pore sizes and pipe diameters offer a wide range of applications in various types of soils.

• 200 µm - used in fine sand & fine grained soils, & for water resource wells.

• 40 µm & 80 µm - suitable for sandy, silty areas.

• 20 µm & 40 µm - provide superior sparging and soil vapor extraction.

The small pore sizes are also suitable for treating problems such as contamination with mineral oil hydrocarbons
