M-Pack Prepacked Well Screen
When setting monitoring wells, some sub-surface conditions such as caving, heaving or silty sand make conventional sand/gravel pack placement difficult or impossible. The solution is to use a prepacked well screen manufactured by Rice.
Benefits include:
- Convenience
- Allows drilling of smaller boreholes.
- Reduces cuttings and their disposal.
- Quick and simple installation.
- Performance
- Sand filter pack is uniform and without voids.
- Allows for sediment-free sampling.
- High screen open area.
The M-PACK™ well screen is designed in one integrated unit with a centralized PVC inner well screen, a filter sand pack and an outer conductor screen made of woven stainless-steel mesh.
-
Rice prepacked well screens offer the following comparative advantages to others:
- Two outer screen options: woven stainless-steel mesh (M-PACK™) or slotted PVC screen (P-PACK™).
- The M-PACK™ design comes with unique removable PVC thread adaptor which secures the sand and mesh in place for trouble-free performance. Plus, this allows for re-packing the sand and re-using the prepacked well screen resulting in additional life and reduced operating costs.
- Dependable product Inventory – waiting at the ready when you need it.
- Custom manufacturing – we can provide prepacked well screens that are not available from others or simply do not exist.
- Full service support – experienced and knowledgeable technical support staff ready and waiting to help.
