COAL BED GAS WELL APPARATUS AND METHOD WITH MINABLE NON-SPARKING TUBULAR AND VALVE COMPONENTS

摘要

Disclosed is a wellbore configuration for use in coal bed gas production comprising tubing and down hole equipment made from non-sparking materials which can be mined out with the coal.

主权项

1. A method of drilling, treating, and recovering gas from a coal bed formation prior to mining the formation, comprising the steps of:
drilling a wellbore to extend horizontally in the coal bed formation; providing tubing and a plurality of valves: installing the tubing and a plurality of valves in the wellbore with the plurality of valves spaced along the wellbore; selectively opening the valves and pumping treatment fluids from the tubing, through the valves and into the coal bed formation; producing gas through the tubing from the coal bed formation; and thereafter, mining the materials, tubing and valves located in the coal bed without creating sparks.
