We are a leader in the rehabilitation of wells and well equipment.
Well rehabilitation is periodically required during the life of a well, as groundwater contains bacteria and minerals which cause well plugging. Screens, gravel pack and formations may become blocked, reducing the capacity and efficiency of the well. Additionally, plugged wells often experience biological issues or bad samples.
We offer complete diagnostic and rehabilitation services for existing wells, pumps and related equipment through a network of local offices throughout our geographic markets in the United States.In addition to our well service rigs, we have equipment capable of conducting downhole closed circuit televideo inspections. This is one of the most effective methods for investigating water well inefficiencies, which enables us to effectively diagnose and respond quickly to well and pump performance problems.
By utilizing existing data and performing additional testing such as bacteriological well evaluations and chemistry analyses we are able to pinpoint the plugging mechanism. This process is important in order to determine which tools to use in order to obtain "the greatest long term results"
Our trained and experienced personnel perform a variety of both chemical and mechanical well rehabilitation techniques. Layne can assist in setting up a preventative well and pump maintenance program. A preventative maintenance program will protect, maintain and extend the life of your very valuable asset. These programs allow for scheduling and budgeting throughout the year to reduce unexpected costly emergency repairs, (no more fire drills) allowing operators to pump wells at their maximum safe and efficient capacity while reducing energy cost.
- Chemical - When employing a chemical method of well rehabilitation, Layne technicians will customize the proper blended chemistry and concentration for your well. Chemical well rehabilitation involves tailored strategies, based upon the cause of the problem, well construction details, and type of formation. The solutions must achieve effective deposit removal, with good agitation and penetration into the surrounding formation.
- Brushing - Brushing the inside of a well is considered a pre-treatment. It allows us to remove mineral deposits and corrosion byproducts inside the well. This mechanical pre-treatment opens the screened area so chemicals can easily be injected through the screens.
Dual Swabbing - Utilizing dual swabs allows us to place chemicals exactly where we want them by isolating zones with rubber discs. Dual swabbing while injecting chemicals adds the agitation and energy required to properly disperse the chemicals and assist in the reaction of acids on mineral deposits. Additionally, dual swabbing while airlifting allows for agitation required to properly redevelop the well by removing spent chemicals, dissolved minerals and dislodged formation materials.
Jetting - High pressure jetting has been a proven method of opening plugged screens.
Boreblast ™ - is a rehabilitation tool which can deliver up to 3500 psi of energy which provides percussive movement needed to break up deposits. Utilizing this technology has proven successful on it’s own but with the addition of chemicals this tool will deliver these chemicals deep into the formation and assist in dispersing mineral deposits with the powerful agitation employed with its use.
Sonar Jet - Is a custom fabricated detonating cord that produces a harmonic frequency of shock waves to assist in mineral deposit removal.
Aqua Freed - is the controlled injection of liquid (CO2). Liquid CO2 expands 540 times from a liquid phase to the gaseous phase. It is this expansion which produces a great amount of energy to dislodge materials from the well screen, gravel pack and formation. This expansion also allows for greater penetration into the surrounding formations more than any other method of rehabilitation.
