COAL BED METHANE (HA FWF) STICKS were designed to be used in shallow gas wells with low bottomhole temperatures. They are fast acting sticks and will dissolve in cold fluids where other sticks can require more time to dissolve. COAL BED METHANE (HA FWF) STICKS are primarily used to remove water from gas wells. This foaming action decreases the hydrostatic backpressure which increases gas production that further enhances the foaming action until the well unloads.
