FAQ on Data Layers:
Q: Why are some layers are grayed out and un-clickable?
A: Some layers are only visible at certain map levels and will be grayed out when not within the visible range. Wells are only visible from levels 6 to 14. Read the tooltip for additional information.
Q: What is the column of icons on the right that change when the map loads?
A: These icons show the status of each data layer. If the data layer is unavailable then a red "X" will appear.
Q: Where can I find the information about data layers (a.k.a. metadata)?
A: The information about data layers used can be found here: Data Layer Info page.
Q: What can I add to Well Finder?
A: Currently, Well Finder can only consume data hosted on an ArcGIS Server.
Q: Where can I find data layers to add to Well Finder?
A: The federal, state, and some local governments have ArcGIS servers by which they release their GIS data. A good place to start is California Department of Technology's ArcGIS Services Directory. Also, the Department of Conservation has GIS data on its ArcGIS Server. See Tips and Tricks: Add A Layer section to learn how layers can be added to Well Finder.
Q: What is EPA Wells for Aquifer Excemption Review?
Navigate the map to a location in California; be sure the map is at level 6 or higher on the Zoom Slider so wells can be visible.
When you see the well(s): Click on a well in the Map Area to look up information on the individual well. Click on the bookmark icon button to add the well to a list of
bookmarks to access later. Note: The bookmark holds the map extent of the current view so make sure you bookmark the well in a position on the map you want.
See Detailed Information: Zoom Slider for information on the level and the scale it represents.

Add A Layer
Well Finder currently only supports data layers hosted on ArcGIS servers. The following steps show how data layers can be added to Well Finder using the DOC's ArcGIS Services Directory.
Open a web browser and go to an ArcGIS REST Services Directory.
Click a folder of interest and a layer you want to add to Well Finder. Example: Base > Base_Water
Copy the URL in the address bar.
Switch to Well Finder in your web browser and click on Add A Layer buttom.
[WellFinder]Select All Wells
The Select All Wells button queries all wells (excluding Notices and Permits) within the current map extent, selects them on the map, and adds them to the Well List. Note:
The function will not remove wells that are already on the Well List, but it will change the well selection.
When the map is moved, the map extent will also change. You can run the function again to select all wells within the map extent.
If more than 1000 wells are within the current map extent, the application will reduce the size of the extent, as if the map is zoomed in one level, and query again. The process will be repeated until the number of wells found is less than 1000, or the map has reached the highest possible level. Then, the application prompts the users to decide whether they want to zoom in to the reduced map extent or remain at the current map level.
The Select All Wells button will remain disabled and only become active when wells are visible.
The datum used by Find By Lat / Long is WGS84 in order to work with the Web Mercator map projection, but the Latitude and Longitude stored in the DOGGR data are based on NAD83 datum.
Both Latitude and Longitude are limited to the extent of California. (That is roughly, 32.0 < Latitude < 42.5 and -125.0 < Longitude < -113.5)
The negative and positive signs can be omitted when entering latitude and longitude.
On desktop, the coordinate shows the latitude and longitude of the mouse cursor on the map, but on touch devices (tablet and phone), it is the position where the map was last tapped on.
[WellFinder]Notice and Permit Layer Filter
The Layer filter button opens a popup window that allows users to change the types of notices and permits displayed on the map by checking or unchecking a type of Notice and Permit. By default, all types of notices and permits are checked. Last, you can select/deselect the entire column of options by clicking on Well Notices All.
[WellFinder]DOGGR Well Layer Filter
The Layer filter button opens a popup window that allows users to limit wells displayed on the map by both Well Type and Well Status. The default setting is no filter, so all wells initially are checked and displayed on the map. To select/deselect an entire row or column, you only need to click on a given well type or a well status. The label,Well, at the upper left corner can be used to select/deselect the entire grid of options. You can hover over a Well Type to see the full name of a Well Type in the tooltip.

Wells are only visible on the map at level 6 and higher. Notices and Permits are visible at all levels. As shown in the screenshot above, using mouse cursor to hover over the level number on Zoom Slider brings up a tooltip that show the map scale at given level .
Map Scale Bar
A map element is used to graphically represent the scale of the map defined as the ratio of a distance on the map to the corresponding distance on the ground. The map scale bar will change dynamically based on the map extent, the map scale, and the latitude.
For projection information and a known issue when using the scale bar, read Additional Information.
The Overview Map uses the same background image as the basemap. The green rectangle inside the Overview Map represents the map extent of the Map Area. You can click and drag the green rectangle to move the main map to a location of interest.
To open and close the Overview Map, click on the arrow at the top right corner of the map to open/close the Overview Map. The Overview Map is closed by default.
[WellFinder]DOGGR Well Legend
Well symbols are based on a combination of Well Types and Well Status.
Note: The legend is static.
The road legend at levels 12 and higher
Note: At levels 12 and higher, ESRI Street Map is currently only available in urban areas. Therefore, DOC provides its own GIS services to fill the gaps.
An InfoWindow is a popup window with information about a clickable map feature (including well and notice & permit) when it is selected or clicked on.
A toolbar at the bottom of the InfoWindow contains following functions:
Zoom To - Zoom in to the selected feature to have a closer look.
Get Direction - If the current location of the device is known, users can use this function to route to the selected map feature via Apple Map for iSO devices or Google Map for the non-iSO devices.
Show Detailed Information - This button pulls all the information about the selected map feature in the database table and displays it in a popup window.
[WellFinder]EPA Wells for Aquifer Exemption Review
This layer displays the well permit locations where a well may be injecting into an aquifer potentially needing an aquifer exemption, pursuant to the US EPA's request.
Wells can be proposed and permitted without ever being drilled or converted into an injection well. Even where a well has been drilled, it may already have been plugged and abandoned or issued other orders preventing injection. Determining the current status of the wells listed here is part of the Division's February 6, 2015, response to the US EPA. This list was generated by identifying one or both of the following characteristics:
The permit is for a well located outside the productive limits of a field as those limits were identified in the State's Primacy application to the US EPA.
The permit is for a well injecting within the productive limits but into multiple zones, one of which may not be exempted by the Memorandum of Agreement (MOA) with the US EPA. The Division acknowledges that many of these wells may not need an aquifer exemption, but a formal determination cannot be made until an evaluation, of the specific well(s) and injection zones(s), is completed.
Please note that the evaluation of these well permits has begun and the list continues to change. However, to be consistent with the US EPA's letter to the Division dated December 22, 2014, and the Division's response on February 6, 2015, the list contains the permitted wells into non-hydrocarbon producing zones as of August 2014, and a list of the enhanced oil recovery permitted wells as of October 2014. The Division will update the list periodically.
The link to Well Information from the Well InfoWindow provides detailed information from the Well Finder geodatabase. Scrolling is required to view all of the well information. Internet Explorer is the only browser that allows direct copy to the clipboard. All other browsers require users to select all the text and then manually copy to the clipboard (Crtl + C).
The modified Mercator projection used by Google, Bing, and ArcGIS Online is not designed to minimize distortion. Instead, the projection based on a perfect sphere sacrifices some accuracy for convenience working with cached map tiles. As the result, the farther away from the Equator, the more distortions (of shapes, areas, directions, and/or distances) are evident. This means that measuring distance using ESRI's built-in scale bar can be inaccurate. For more information: visit the ESRI blog post "Measure distances and areas when your map uses the Mercator projection"
API Number - American Petroleum Institute Well Number (also called API) is a unique, permanent, numeric identifier assigned to each oil and gas well in the US. An API Well number can have up to 14 digits divided into State Code (2 digits), County Code (3 digits), Unique Well Identifier (5 digits), Directional Sidetrack Code (2 digits), Event Sequence Code (2 digits). Currently, API Numbers in the DOGGR Well Finder database consist of 8 digits - County Code (first 3 digits) and Unique Well Identifier. For more information: visit the Wikepedia page on the API Well Number
District Number - DOGGR splits up California by districts. [See the DOGGR Contact Page for information about the different districts and the contacts.]
Map Extent - The "extent" of the map is the entire rectangular area of the Map Area. The extent changes as you pan, zoom, or use a Find tool. The map elements (e.g. zoom slider, overveiw map, map scalebar, copyright notice and links, and logo) do not affect the extent of the map.
OPI - Online Production and Injection is another online querying tool for online production information of individual wells for State of California, Department of Conservation, Division of Oil, Gas, and Geothermal Resources. Note: Information about confidential wells is not available on this website.
OWRS - Online Well Record Search is another text based querying tool for multiple scanned well records for State of California, Department of Conservation, Division of Oil, Gas, and Geothermal Resources. Note: Scanned well records for confidential wells are not available on this site.
