👉 Wisses are a type of natural gas well. They are drilled to extract natural gas from deep underground rock formations, often in shale or sandstone formations. The process involves using hydraulic fracturing (fracking) to break open the rock and release natural gas, which is then brought to surface for processing by a wellhead equipment. Wisses are typically used in large-scale oil and gas exploration projects, where they can be used to extract significant amounts of gas from deep geological formations.
