In the energy sector, hydraulic fracturing has changed the way America mines for oil and natural gas. Hydraulic fracturing, or fracking for short, allows the US to tap oil and natural gas reserves that were previously locked away in tight-rock formations. Additionally, fracking can be used to stimulate new production in older wells. The process itself requires a lot of water, as millions of gallons of water, sand and chemicals are pumped underground to break apart the tight-rock formations and release the gas and oil. Hydraulic fracturing liners play a large role in the fracking process. In addition to lining frac pits, hydraulic fracturing liners are used for water containment. Water and chemicals used in the process need to be properly contained in order to preserve the reserves, as well as to protect the environment from chemicals used in the process.
Choosing the Best Hydraulic Fracturing Liners
Once a fracking well is drilled, containment resources are needed for all of the water, sand and additives used in the process. This water mixture, called flowback, is stored in a reservoir or frack pit after being used and extracted from the hydraulic fracturing process. Reservoirs and frack pits require hydraulic fracturing liners for safe containment of flowback. In hydraulic fracturing, secondary containment is also needed, which requires durable liners.Reinforced Polyethylene Liners for Fracking
While there are many different types of liner materials to choose from, reinforced polyethylene (RPE) has many advantages when it comes to hydraulic fracturing.- Comes in a variety of thicknesses - from 12 to 40 mil from BTL Liners
- RPE liners are coated with a low-density polyethylene coating, making it durable and impermeable to some chemicals contained in flowback
- RPE liners feature strong durability and puncture resistance
- RPE can be heat welded together, which means large liners can be formed from panels of the material
- UV resistance is another advantage of RPE, as exposure to sunlight during the hydraulic fracturing process can be a concern in liner durability
