Patent ID: 8398335

Claim:
A method for producing landfill gas from an existing polymeric pipe of a landfill gas recovery well, comprising the steps of (a) transporting a tool, for creating apertures by extending pistons from inside of a housing of the tool to penetrate a wall of the polymer pipe, with a carrier capable of traveling in terrain typical for the location of the landfill gas recovery well, wherein the tool is capable of coupling with additional said tool in the same well; (b) positioning the tool within the landfill gas recovery well; (c) lowering the tool to a first preselected depth in the landfill gas recovery well; (d) extending the pistons with a motive fluid pumped from the carrier into the tool to extend the pistons outside the housing of the tool creating apertures in the polymeric pipe; (e) retracting the pistons after creating the aperture; (f) re-positioning the tool to a second pre-selected depth of the landfill gas recovery well; (g) repeating steps (d), (e) and (f) until a desired number of apertures are created in the polymeric pipe; (h) removing the tool from landfill gas recovery well; and (i) extracting the landfill gas from the landfill gas recovery well with the newly created apertures; wherein the steps (b)-(g) can be operated within the explosive range of landfill gas, and wherein said polymeric pipe have bends, deformations, obstructions or deviation.
