ABSTRACT:
An apparatus and method to internally provide apertures inside PVC, HDPE, or plastic pipe-riser (blank casing) in existing methane gas recovery wells (extraction wells) that have been installed at Municipal Solid Waste Facilities are described. Apertures in methane well risers allow methane gas, LFG derived from the decomposition of waste, to enter the existing riser and extraction system. This process saves time and cost associated with drilling additional wells to retrieve methane gas from subsequent layers of the waste body. The process assists in maintaining regulatory compliance by capturing LFG and preventing it from being emitted into the atmosphere.
