The Federal Institute for Geosciences and Natural Resources, or BGR, is a German Agency which publishes data on oil and gas resources and reserves. BGR data can be accessed [http://www.bgr.bund.de/EN/Themen/Energie/Produkte/energy_study_2014_summary_en.html;jsessionid=15BA5CB5AEB1632F61A4DB9B0A3DC1A7.1_cid292&nbsp here]. This data is useful because resources and reserves are broken into their unconventional sub-components such as shale gas, tight oil, and coalbed methane. This is important in initializing total resources and reserves in the model, especially with the rise in unconventional gas and oil production in North America.

In preparing these series, I first downloaded the relevant energy reports from the BGR website, or are available through a google search of "BGR Energy Resources [YEAR]". I then exported the appropriate tables from these PDFs into separate excel sheets. Next, I broke these excel sheets down into the individual series, each of the 17 series onto its own excel sheet.
In preparing these series, first downloaded the relevant energy data from the [https://www.bgr.bund.de/EN/Themen/Energie/Produkte/produkte_node_en.html?tab=Energy+Studies BGR website], or are available through a google search of "BGR Energy Resources [YEAR]".  


Each one of these 17 sheets has tabs for raw data for each year, formatted data for each year, and data for import (including data for all years). The [YEAR] tabs have the raw data pulled from the two Energy Study excel sheets. The [YEAR] Formatted tabs have the same data as the [YEAR] tabs, only it has been formatted into a IFs-compatible format. The Data for Import tab has these two years combined.
* The study reported data in previous year.
* '''Missing BGR Energy Study 2020, thus, we don't have data in 2019.'''
* Starting from 2019, BGR also provided data in excel spreadsheet. Thus, the data after 2018 can be extracted from excel, not pdf.
* The data before 2018 need to be extracted from BGR reports in pdf.
* '''The most recent data can be downloaded in BGR Energy Study in Germany version from [https://www.bgr.bund.de/DE/Themen/Energie/Produkte/produkte_node.html?tab=Energiestudien here].'''
** The latest update was in April, 2024. The data in 2021 and 2022 were downloaded from the BGR Energy Study in Germany version.


Finally, I took all the Data for Import tabs from the 17 sheets and combined them into one sheet (Energy Series Final Version for Import). I then imported all series into Ifs from this sheet. Once I imported the data into Ifs, I blended the series with the existing data and exported all the series to the Access table “Imported Series” in folder “Imported Series”.
Combined new data and current data in IFsHistSeries.db.

Differences between resources and reserves: “…[That] part of a mineral resource, which has been fully evaluated and is deemed commercially viable to work, is called a mineral reserve [in effect, resources will always be larger than resources]” In effect, resources shouldn’t change over time, while reserves can.

Sudan and South Sudan: Most of the time, BGR lists reserve and resource values for "Sudan" and "South Sudan" individually. On occasion though, BGR will use "Sudan and South Sudan" as a composite, representing aggregated data for both of the countries but not providing it on an individual basis. This is rare, and only takes place in series EnReserGasBGR and EnResorGasBGR. In these cases, I calculated the values for "Sudan" and "South Sudan" by taking the value of "Sudan and South Sudan" and dividing it by the ratio of land mass between Sudan (728,215 sqm) and South Sudan (239,285 sqm). Also, per Steve Hedden, we don't enter values for Sudan in the series EnCumProdGas and EnCumProdOil.

Another issue that needs mentioning is BGR's usage of dashes ("-") in its Energy Reports. Dashes are intrepreted as 0's based on the definition given by BGR in the Energy Reports.

The Federal Institute for Geosciences and Natural Resources, or BGR, is a German Agency which publishes data on oil and gas resources and reserves. BGR data can be accessed here. This data is useful because resources and reserves are broken into their unconventional sub-components such as shale gas, tight oil, and coalbed methane. This is important in initializing total resources and reserves in the model, especially with the rise in unconventional gas and oil production in North America.

Instructions on importing BGR data

Process of importing and blending:

In preparing these series, first downloaded the relevant energy data from the BGR website, or are available through a google search of "BGR Energy Resources [YEAR]".

  • The study reported data in previous year.
  • Missing BGR Energy Study 2020, thus, we don't have data in 2019.
  • Starting from 2019, BGR also provided data in excel spreadsheet. Thus, the data after 2018 can be extracted from excel, not pdf.
  • The data before 2018 need to be extracted from BGR reports in pdf.
  • The most recent data can be downloaded in BGR Energy Study in Germany version from here.
    • The latest update was in April, 2024. The data in 2021 and 2022 were downloaded from the BGR Energy Study in Germany version.

Combined new data and current data in IFsHistSeries.db.

Some notes on the formatting process:

In 2014, term changed from Shale Oil to Tight Oil (applies to Series EnReserShaleOil and EnResourceShaleOil) not to be confused with Tight Gas.

Table numbers don’t stay the same over different years in the energy reports.

Differences between resources and reserves: “…[That] part of a mineral resource, which has been fully evaluated and is deemed commercially viable to work, is called a mineral reserve [in effect, resources will always be larger than resources]” In effect, resources shouldn’t change over time, while reserves can.

Sudan and South Sudan: Most of the time, BGR lists reserve and resource values for "Sudan" and "South Sudan" individually. On occasion though, BGR will use "Sudan and South Sudan" as a composite, representing aggregated data for both of the countries but not providing it on an individual basis. This is rare, and only takes place in series EnReserGasBGR and EnResorGasBGR. In these cases, I calculated the values for "Sudan" and "South Sudan" by taking the value of "Sudan and South Sudan" and dividing it by the ratio of land mass between Sudan (728,215 sqm) and South Sudan (239,285 sqm). Also, per Steve Hedden, we don't enter values for Sudan in the series EnCumProdGas and EnCumProdOil.

Another issue that needs mentioning is BGR's usage of dashes ("-" or "—") in its Energy Reports. Dashes are intrepreted as 0's based on the definition given by BGR in the Energy Reports.

BGR occasionally uses "n.s." (or "n. s.") in its data, which is intrepreted as a null value. In the German translation, "k. A." is used instead of "n.s.".

If there is a less than sign in the data, it is dropped and the value preceding it is entered as is. Eg. <0.05 is entered as 0.05.
