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...

D62: Coalbed Methane Control Well Requirements

Coalbed Methane is a Biogenic #Gas, extremely high C1, plentiful here in Alberta, perfect for heating homes, markets, churches, and schools on our clean natural gas grid. Eventually maybe even #LNG ferries and trains. 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 DRY, only pressure testing is required to meet control well requirements;...

D62: Coalbed Methane Control Well Requirements

Coalbed Methane is a Biogenic #Gas, extremely high C1, plentiful here in Alberta, perfect for heating homes, ranches, greenhouses, and community centres on our clean natural gas grid. Eventually maybe even #LNG buses and trucks. Coalbed developments all require at least one #AER Control Well. Control wells may be for Desorption test and/or Pressure and Flow Control testing. Initial Pressure tests (segregated pressure for each coal zone) must be submitted within four months of Control Well authorizations. Tests conducted up to twelve months...

D62: Coalbed Methane Control Well Requirements

Coalbed Methane is a Biogenic #Gas, extremely high C1, plentiful here in Alberta, perfect for heating homes, farms, greenhouses, and businesses on our clean natural gas grid. Eventually maybe even #LNG exports. Coalbed developments all require at least one #AER Control Well. Control wells may be for Desorption test and/or Pressure and Flow Control testing. Desorption testing is the first priority because scheduling annual pressure and flow control #welltests depends on a “wet” or “dry” gas designation. Minimum Desorption Testing...

D65: Resources Applications for Oil and Gas Reservoirs

Planning a Section 4.3 application for Underground Gas Storage? Maximum bottomhole injection pressure and maximum average reservoir pressure data are required to define the upper limit to the operating pressures of the scheme (i.e. maximum wellhead injection pressure). A complete tabulated pressure history of the pool (date, well, type of test, stabilized pressure) is also required, with a P/Z versus cumulative gas production plot (if the pool is non-associated gas), or material balance calculations (if storage is into a gas cap in...
