CBM currently supplies approximately eight percent of the Canada's natural gas production, and is an important facet of the nation's energy mix. The depletion of natural gas reservoirs along with the increased need for natural gas combines to drive the evolving CBM production. CBM is abundant in Alberta, with a significant amount of methane present in the Horseshoe Canyon and Ardley Coals, as well as in the Mannville Group formations. Of these reservoirs, it is the wet Mannville formations that are of interest to our new and exciting artificial lift solutions.
Many artificial lift problems arise in CBM for a number of reasons. Of most importance are the harsh environments that must be combated - high iron content water, sludge and contaminants, sand and particulates. Great concern is given to the fact that the water from these wells is pumped in the low to medium range. Raise Production's Hydraulic Submersible Pump (HSP) was specifically designed to overcome the harsh well conditions seen in these CBM wells.
The HSP has been used by many of the top CBM players and has shown great success relative to other artificial technologies. An Alberta Oil article outlines some of the success encountered by EnCana, one of Canada's largest CBM player.
