Wells that have been hydraulically fractured according to the California Department of Oil, gas and Geothermal Resources (DOGGR).  The data was updated 7/31/13.
While there are over 215,000 drilled wells known to California DOGGR, 1,216 of those are flagged as having been hydraulically fractured and 1,205 have lat/lon data. This map contains those &quot;frac'ed&quot; wells identified by the California Department of Oil Gas and Geothermal Resouces. Eight wells did not contain GPS coordinates and 3 were duplicates, and therefore were not included.   The majority of the fractured wells are oil and gas development, although not all. Some are support wells, such as water disposal and steam flood wells. Other FracTracker maps and layers contain amended datasets, which limit the dataset to just oil and gas wells. <span style='font-size:11.0pt;line-height:115%; font-family:&quot;Calibri&quot;,&quot;sans-serif&quot;;mso-ascii-theme-font:minor-latin;mso-fareast-font-family: Calibri;mso-fareast-theme-font:minor-latin;mso-hansi-theme-font:minor-latin; mso-bidi-font-family:&quot;Times New Roman&quot;;mso-bidi-theme-font:minor-bidi; mso-ansi-language:EN-US;mso-fareast-language:EN-US;mso-bidi-language:AR-SA'>.
