D62: Coalbed Methane Control Well Requirements
Coalbed Methane is a Biogenic #Gas, extremely high C1, plentiful here in Alberta, perfect for heating homes, stores, shops, and sports facilities on our clean natural gas grid. Eventually maybe even #LNG cruise and container ships. Coalbed (#CBM) developments all require at least one #AER Control Well. Control wells may be for Desorption test and/or Pressure and Flow Control testing. Annual pressure and deliverability tests are required. For development in a single coal zone that is WET, both the pressure data and the flow data may be collected from the same control well. Alternatively, pressure requirements may be met with an observation control well. Flow test requirements may be met through reported production from exactly the same coal zone (precluding expense of running another flow meter test or #PLT). Annual tests may be conducted at any time during the calendar year.
