ALBERTA WELL FILTERING STUDY OVERVIEW, WELLHEAD ANALYSIS, METHODOLOGY, AND DASHBOARDS
|
It is with pride that CanGEA announces the release of our AB Well Filtering Report titled, "Potential of Geothermal Energy from Co-Production in Alberta using Existing O&G Wells." The purpose of this study was to identify oil and gas wells in Alberta as of October 31, 2016 with the potential to be repurposed for geothermal heat and electricity. The results indicate that there is significant potential for geothermal development, able to be harnessed by Alberta’s pre-existing oil and gas expertise.

Filtering Study Overview
As of October 31, 2016 Alberta has 60,935 wells with bottom hole temperatures greater than 60°C. Of those 7,702 are hotter than 90°C and 500 are hotter than 120°C. The filtering study is an outgrowth of CanGEA’s first Alberta geothermal resource assessment, which was funded in partnership with the government of Alberta. The temperature of a well determines what it can be used for. The 60°C wells are classified as direct use and can heat homes and grow fresh produce in greenhouses year‑round. 90°C wells are classified as industrial heat and can be used for such businesses as food processing, and refrigeration. Lastly, Alberta’s 120°C wells can be used for power generation. Geothermal power is base load and is a viable option for Alberta. If only 10% of these geothermal opportunities are developed then that is still ~6,000 new geothermal systems in Alberta providing heat and/or power, and employment opportunities for Albertans. The geothermal future in Alberta is looking bright because our industry is re-imagining Alberta’s oil and gas fields as a key partner in renewable energy development Wellhead Analysis - Data Obtained October 31, 2016 In Alberta, there are nearly 600,000 wells registered in the Alberta Energy Regulator's database. To determine which wells have the potential for geothermal applications, an extensive filtering and quality control process was applied to these wells to ensure data accuracy. The Wellhead Analysis summarized the methodology used to discover the potential for geothermal energy in Alberta using existing oil and gas wells. The full geological and filtering methodology report can be found in the appendix of the Wellhead Analysis. Well data (obtained October 31, 2016) for all wells in Alberta was exported from geoSCOUT. This data included true vertical depth and temperature data such as bottom hole temperature, log based bottom hole temperature and drill stem test bottom hole temperatures. Methodology The methodologies (phases of filtering) taken to achieve a final filtered list of potential direct use and/or co-generation geothermal wells for development in Alberta by categories (i.e. Direct Heat, Industrial Heat, and Power Generation).

The Questions (each their own dashboard):
The purpose of the study was to illustrate the size of the opportunity to co-produce geothermal energy from existing Oil & Gas wells in Alberta. The goal of the study was to gain better public awareness and engagement with these results; CanGEA worked with Fuzeium to create an interactive experience to complement the report. The Approach A pair of interactive dashboards were created; enabling the general public to easily connect with the results of this study and imagine how geothermal co-production could impact and benefit their communities. Insights Over 60,000 oil and gas wells in Alberta have the potential for geothermal production. Three categories, based on the temperature at the bottom of the well:

This product contains a pair of interactive dashboards to view the results of this study. What this package contains: (1) Which O&G Wells have Potential for Geothermal Power or Heat Applications? Allows the user to view over 60,000 oil and gas wells in Alberta that have the potential for geothermal production. The wells are divided into three categories, based on the temperature at the bottom of the well: -Power Generation (>120°C) : about 500 wells -Industrial Heat (>90°C): about 7,200 wells -Direct Heat (>60°C): about 53,000 wells (2) Which Potential Geothermal Wells are Close to Relevant Infrastructure? Allows users to navigate through 3 scenarios (Direct Heat, Industrial Heat, Power Generation) where the wells are all within 10km of relevant infrastructure. Additionally allows users to compare municipality vs. road distance and also to select a municipality to see all nearby wells. This product also contains a free copy of the Main Filtering Study Report, Technical Analysis and Methodology: The main report was prepared for the “Potential for Geothermal Energy from Co-Production in Alberta using Existing Oil and Gas wells,” also known as the “Filtering Study." This portion of the filtering study is an overview of what geothermal energy is, how it is developed, and the various ways it can be used by the public and private sectors across Alberta. This product also contains 1 freedownload of the raw data (.xlsx) used to make the dashboard.
