AN ALTERNATIVE APPROACH TO WATER WELL REPAIR; EXTENDING WELL SERVICE LIFE AND IMPROVING WATER QUALITY, WHILE MINIMIZING MAINTENANCE COSTS AND SERVICE DOWNTIME
- Repair Holes in Damaged & Deteriorating Casing
- Our FDA approved Neoprene backing seals in damaged areas of the casing.
- It is effective in preventing sand intrusion and cascading water while improving water quality and production.
- Minimal Interference
- Our swage patch is 1/4″ thick, meaning the patch won’t interfere with installation of the existing pumping equipment.
- Our lining repairs damaged casings without losing volume of the well.
- Well owners can keep existing pumping equipment.
- Effective Alternative to Drilling a New Well
- Swaging creates a long-lasting repair for well casing and screens.
- Swaging is a cost effective and time efficient alternative to drilling a new well.
- Improved Water Quality
- Swage patches can be used in all types of well construction.
- The patch can line areas where there is undesirable water infiltration from holes in the well casing to improve overall water quality.
Patches are custom-designed for each specific well taking into consideration the minimum running diameter required, the necessary collapse resistance, the length needed as well as the well site characteristics. Patches are usually 1/4-inch to 3/4-inch thick and they can be up to 20 feet long. They can also be welded in line to form longer sections. The ends of a patch are uncoated to achieve a smooth tapered transition to the well casing to prevent hanging up on the patch when running pumps or other equipment.
In PVC and small diameter wells, short thin stainless-steel sleeves are used as patches to maintain needed clearance for passage below.
Water Well Solution’s Swaging Well Casing Patch System is a cost-effective and long-lasting solution to repair and reline damaged areas of a well casing or well screen with minimal diameter loss and no cementing. This precision repair technology consists of inserting a patch – an expandable stainless-steel (SS) rube encased with a vulcanized FDA approved elastomer coating – into a well casing, running it to the desired depth and then applying it to the damaged area using a high-pressure inflatable packer. The inflatable packer is placed inside the patch at surface and once at depth, it inflates and exerts an outward force on the patch. Once the pressure exceeds the yield capacity of the SS tube, the patch expands in diameter until the neoprene backing is compressed between the steel patch and the well casing effectively sealing the damaged area. The patch creates a tight-fitting sleeve across the damaged area and works even on irregular surfaces thanks to its high tolerance expansion.
This versatile technology can be used to solve many problems in both screen and rock wells, including broken casing, holes in casing or well scree, cascading water, sand pumping, contaminated water, or blocking areas of poor water quality.
