The source of information for all Alberta Well Data is the website of Alberta Energy Regulator and all The information was extracted from the following reports:

1) Statistical Report ST37 – well list and following fields:

• well identifier

• well name

• license number

• field/pool and/or area/deposit

• operator

• licensee

• total depth

• finished drilling date

• well status

The information about the meaning of each field in the well table is obtained from: http://www.aer.ca/documents/sts/St37-Listofwellslayout.pdf

Tables

The following are summaries of the Important tables within the Statistical reports mentioned above:

Table ab_well

Column Name	Description
LOCATION column	This column in the database represents well id in UWI format. In this id is encoded the location of well. The information on decoding the meaning can be found here: dl.ppdm.org/dl/551
WELL_ID column	This column contains the well id in the well DNS format. It encodes the location of the well and the information on the meaning of each digit can be found here: dl.ppdm.org/dl/551
WELL_NAME column
POOL_CODE column	References to ab_pool_code table
OS_DEP_CODE column
FINAL_DRILLING_DATE column
TOTAL_DEPTH column
WELL_STATUS_CODE column	This field encodes the status of the well. The information from this field is decoded and added to the table in the following fields:,FLUID, MODE, TYPE, STRUCTURE. The information is decoded according to: [1]
WELL_STATUS_DATE column
FLUID column	Obtained from WELL_STATUS_CODE
MODE column	Obtained from WELL_STATUS_CODE
TYPE column	Obtained from WELL_STATUS_CODE
STRUCTURE column	Obtained from WELL_STATUS_CODE
CONFIGURATION column	Contains information if the well is horizontal. The data was loaded to this table from the list of horizontal well list (see the 6-th resource in the resource section)
HORIZONTAL_WELL column	Contains information if the well is horizontal. The data was loaded to,this table from the list of horizontal well list (see the 6-th resource,in the resource section)
LONGITUDE_DECIMAL column	This information was extracted from the online converter (see the 7-th resource in the resource section)
LATITUDE_DECIMAL column	This information was extracted from the online converter (see the 7-th resource in the resource section). NOTE: extracted information for this column has a positive value. In order to see the actual location of the well in Google Maps, this location has to be turned to negative value. I left this value to be positive in order to be consistent with the source.
