Description

Alberta Innovates Technology Futures was contracted by Alberta Environment to review and evaluate the data held in the Baseline Water Well Testing database to determine trends in baseline conditions and any observable changes in water quality of wells that were tested more than once. Includes several recommendations for future data capture and entry.

Potential for gas migration due to coalbed methane development

Description

Coalbed gas (CBG) effectively consists of methane with minor amounts of ethane and propane, but no hydrogen sulphide (H2S). Recognition of CBG as an increasingly important energy resource has led... More ≫

Description

Coalbed gas (CBG) effectively consists of methane with minor amounts of ethane and propane, but no hydrogen sulphide (H2S). Recognition of CBG as an increasingly important energy resource has led to rapid expansion of exploration activity. Rapid development started in the 1980s in the western United States of America (USA), and has spread over the last six years to the Western Canadian Sedimentary Basin (WCSB). Increased production activities have brought increased awareness of environmental issues surrounding CBG development. In particular, reports of negative experiences associated with early CBG development in the USA have raised stakeholder concerns in Canada. Alberta CBG development has largely avoided the water resources issues experienced in the USA from CBG exploitation for two reasons. The major CBG resource plays in Canada to date have been in ‘dry’ coals, while ‘wet’ CBG coals developed in the USA required dewatering in order to recover the gas. Secondly, the rapid...

A comprehensive literature review on the applicability of free and dissolved gas sampling for baseline water well testing : final report

Description

This report summarizes and evaluates currently available methods for free gas and dissolved gas sampling from water wells and discusses their applicability to groundwater testing near coalbed... More ≫

Description

This report summarizes and evaluates currently available methods for free gas and dissolved gas sampling from water wells and discusses their applicability to groundwater testing near coalbed methane operations in Alberta. The ultimate goal is to assess advantages and disadvantages of the currently available techniques for determining the chemical and isotopic compositions of free and dissolved gases in groundwater obtained from water wells. Another objective was to evaluate whether suitable techniques exist to reliably analyze the chemical and isotopic composition of dissolved gas in groundwater, and if so, whether this would add important new information.

Description

Alberta Research Council was contracted by Alberta Environment to conduct four reviews of complaints about coalbed methane activities affecting private water wells, to independently assess the scientific evidence and provide conclusions identifying whether or not the water wells had been impacted by coalbed methane or conventional oil/gas extraction activities.

Description

A multi-stakeholder advisory committee chaired by Alberta Energy was established in November 2003 to review the regulations that govern coalbed methane/natural gas in coal development to examine the balance between protecting the environment and responsible development. The guidelines in this document summarize the rules and processes to guide coalbed methane/natural gas in coal development where non-saline water is involved that were in place at the time the committee was formed.
