Tips and Tricks

Navigate the map to a location in California; be sure the map is at level 5 or higher* on the Zoom Slider so wells can be visible.
When you find the well(s): Click on a well in the Map Area to look up information of an 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.

* Level 13 is at the top of the Zoom Slider. See Detailed Information: Zoom Slider for information on the level and the scale it represents.

Map Navigation
Map navigation includes both mouse and keyboard interactions.

Detailed Information

Select All Wells
Select All Wells button image
The Select All Wells button adds all wells (does not include Notices and Permits) within the current map extent to the Well List and keeps those wells selected. The button will not remove wells that are already in the Well List. If the map is moved, extent change, this button must be clicked on again to get all the wells in the new map extent. If there are more than 1000 wells within the current map extent, the application will reduce the size of the extent and query again. The process will be repeated until the number of wells found is less than 1000 or the map extent is 20% of its original size. 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 only becomes active when wells are visible. Otherwise, the Select All Wells button does not work.

Latitude, Longitude
The Find By Lat / Long is in WGS84 to work with the Web Mercator mapping system, but the Latitude and Longitude stored in the DOGGR data is in NAD83. It is important to keep this in mind when searching for a well location.

When doing a Find By Lat / Long, the ranges of 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).
Also, the negative and positive signs are not needed when entering latitude and longitude. The web map assumes signs appropriate to California.

The position information shows the latitude and longitude of the mouse cursor. For a tablet, it will show the position where the map was last tapped on.
Notice and Permit Layer Settings
Notice and Permit Layer Settings image
The Layer Settings button Layer Settings Button image opens a menu that allows users to change the types of notices and permits that show up. On the Layer Settings menu window, select/deselect by type to make notices and permits visible/invisible on the map. By default, all notices and permits are checked and displayed on the map. By clicking on top area of Show, users can select/deselect the entire column of options.

DOGGR Well Layer Settings
DOGGR Well Layer Settings image
The Layer Settings button Layer Settings Button image opens a menu that allows users to change the types of wells that show up. On the Well Filter menu window, select/deselect by well type and/or well status to make wells visible/invisible on the map. By default, all wells are checked and displayed on the map. A well type or a well status can be clicked on to select/deselect an entire row or column. By clicking on Well at the upper left corner, users can select/deselect the entire grid of options. In addition, a tooltip appears when the mouse pointer hovers over a Well Type.
(See Detailed Information: Well Types.)

Built-in Bookmark Map Capability
Bookmark Map Diagram
  • Option 1: Bookmark from Details side panel
    • Open the Details side panel.
    • Use a Bookmark: Click on the name.
    • Add a Bookmark: Click on "Add Bookmark" and enter a name for the bookmark. The bookmark will be of the current map extent.
    • Edit a Bookmark name: Click on the pencil icon and edit the name of the bookmark.
    • Delete a Bookmark: Click on the "X" icon and the bookmark is instantly deleted.

  • Option 2: Bookmark from Well InfoWindow (See Glossary: Well InfoWindow.)
    • Click the Add Bookmark Icon on the Well InfoWindow.
    • A bookmark is added to the Bookmarks list with the API and the Details side panel opens if not already open showing the Bookmarks panel.

  • Option 3: Bookmark Keyboard Shortcut
    • Keyboard shortcut: Ctrl+Alt+B
    • The keyboard shortcut will put in a temporary name (in the format of "Bookmark" + an increasing number) that you can change with an edit. The bookmark is of the current map extent.
    • The keyboard shortcut opens the Details side panel if not already open showing the Bookmarks panel.

Note: Browsers that support local storage will store the bookmarks to the local computer. Browsers that do not support local storage will attempt to save a cookie. These methods allow the saving of the bookmarks so you can continue to use them even if you close the browser. If you use a different browser or you clear out your local storage/cookies then you will lose your bookmarks.
Zoom Slider
Zoom Slider Diagram
Zoom Slider is used to zoom in/out and to indicate the current map level.
The blue bar indicates those levels (5 to 13) where wells are visible. Notices and Permits are visible at all levels.

The two arrow buttons at the top of the Zoom Slider provide access to the Previous/Next map extents.

Level ID Scale
13 1:1,128
12 1:2,257
11 ~1:4,500
10 ~1:9,000
9 ~1:18,000
8 ~1:36,000
7 ~1:72,000
6 ~1:140,000

0 ~1:9,200,000
Footnote: Wells are only visible on the map at level 5 and higher. Notices and Permits are visible at all levels.

Map Scale Bar
Map Scale Bar Diagram
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.
Overview Map
Overview Map Diagram Opened
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.

Opening and closing the Overview Map: Click on the arrow in the top right corner of the Overview Map to control the Overview Map being open or close. The Overview Map is open by default.

DOGGR Well Legend

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.]
California Department of Conservation
Division of Oil, Gas, and Geothermal Resources
Environmental Systems Research Institute - A company that provides GIS/Mapping software and spatial data/services.
An InfoWindow is a popup with information about a well or notice and permit when they are selected or clicked on.
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.
Online Production/Injection
Online Well Record Search
The Public Land Survey System is the surveying method used historically over the largest fraction of the U.S. to survey land parcels before designation of ownership. For more info, visit the National Atlas Page on the Public Land Survey System.
