perforating device 10 is activated at the predetermined depth 34 typically the perforations are done in six inch increments throughout the gas well 12 the ability to recover landfill gas is improved by maximizing the number of perforations in the gas well 12 perforating the gas well too close to the landfill surface 30 can contribute to air infiltration thus perforations should be made approximately twenty feet from the landfill surface 30 the steps of the present invention will be repeated until all desired portions of gas well 12 are perforated after the gas well 12 is sufficiently perforated the perforating device is pulled from the gas well 12 and back to the landfill surface 30 the step of pulling perforating device 10 out of gas well 12 may be accomplished manually or automatically in another embodiment perforating device 10 is attached to a winch that powers pulling perforating device 10 out of gas well 12 and back to landfill surface 30 fig3 illustrates another embodiment of the method of this invention that includes a step for maintaining the amount of methane gas in gas well 12 outside methane gas 39 s explosivity range methane gas has an explosivity range of 5 to 15 by volume this is a necessary safety precaution which ensures the methane gas located in gas well 12 does not ignite to cause.
