Oil and Gas Production and Injection Guide

The Online Production and Injection (OPI) web application allows the viewing of monthly production and injection information from 1977 to present. The information can be viewed by well, or totaled by lease, operator, or field. The information can be printed or exported into an Excel spreadsheet for further analysis. No information on confidential wells is available through this website.

The first screen is the selection criteria to use to find wells. Also, the Preferences button near the bottom allows certain criteria to be changed including the years of interest, show only active wells, and export file format (Excel, dBase, or ASCII).

Wells can be found based on the Field or Operator names (or other criteria). Selecting one of these criteria will bring up an alphabetical listing. Scroll down to your Field or Operator of interest, make a selection, the use the buttons that appear to the left to make further selections. Use the Get Wells button to locate individual wells. Use the Get Sums button to display totals based on the selection criteria you specified.



From this screen, the individual wells for your selection criteria are displayed. To view the monthly reports, click on the API number for the well you want. The listing can be sorted by clicking on the column name. EXAMPLE: To sort by lease name, click on the Lease heading.

Other columns that need explanation include:
Well Stat: The overall status of the well. It can be active, idle, cancelled, new, plugged, or buried-idle.
Pool: The pool code for that well. This corresponds with the reservoir name such as Tulare.
WellType: The well type, or type of activity for that well. Production well types include OG (oil and gas), DG (dry gas), and WS (water source). Injection well types include SF (steamflood), WD (water disposal), WF (waterflood), AI (air injection for a fireflood), SC (cyclic steam), GD (gas disposal), and PM (pressure maintenance or gas injection). GS (gas storage) and LG (liquifield petroleum gas) well types are for injection and production. OB well type is for observation wells.
PWT Status: Pool/well type status relates to that particular pool and well type. It can be active, idle, cancelled, new, plugged, or buried-idle. Some wells do more that one thing, such as a cyclic steam well. For such wells, there will be a line for OG production, and a line for SC injection. So the PWT status on one line of a well can be different from the overall well status. EXAMPLE: A well that was converted from OG production to WF injection will have two lines, one for each segment. The well status will be active, the OG status will be plugged, and the WF status will be active.



The Get Sums button displays the totals by month for the criteria that you have selected. The selection criteria appear at the top of the page.


In addition, the number of wells that meet that selection criteria is displayed just above.

Above that are more buttons that allow you to view additional items such as a graph of the production volumes, the injection totals, a graph of the injection totals, export the volumes to an Excel spreadsheet, and a printer friendly button.


NOTE: When you export to an Excel spreadsheet, there are two ways to save the file:
1. Copy the information and paste it into an Excel spreadsheet.
2. Right-Click on the "Export Data" menu itself, and then “Save Target As…” - and save the file to a folder of your choice.



The identification information on the header of the individual well screen is similar to the selection criteria with some additional information as follows:

Opr Status: the status of the operator, this value can be active or inactive
BLM: If checked, this is a well located on Bureau of Land Management property
Entry: The date the well was entered into the Division’s computer system


The monthly reports can be sorted by most recent first, or in reverse order (oldest first) by clicking on the arrow located on either side of the Date column.


The Stat column is the reported status for that well for that month. The following status codes are used:

01 = Standing idle
04 = Uncompleted or not drilled
05 = Plugged
06 = Shut-in
08 = Other (such as used for observation)


Two other columns that need explanation for production wells are MO (Method of Operation) and Disp (Water Disposition). The following codes are used to describe the method of operation for producing wells:

1 = Flowing well
2 = Jack line method
3 = Beam rod pump
4 = Hydraulic rod pump
5 = Bottom-hole hydraulic pump
6 = Bottom-hole electric pump
7 = Gas lift method
8 = Other

The following codes are used to describe the water disposition for producing wells:

1 = Evaporation – percolation
2 = Evaporation – lined sump
3 = Surface water body
4 = Sewer system
5 = Subsurface injection
6 = Other


For injection wells, two columns that need explanation are Water Source (the source of the injected water) and WaterKind (the kind of water being injected). The following codes are used to describe the source of injected water for injection wells:

1 = Produced from an oil or gas well
2 = Produced from a water source well
3 = Obtained from a domestic water system
4 = Extracted from the ocean
5 = Obtained as waste from an industrial facility
6 = Obtained from a domestic waste disposal or treatment facility
7 = Obtained from another source or combination of the above sources

The following codes are used to describe the kind of water injected:

1 = Salt water
2 = Fresh water
3 = Water combined with chemicals such as polymers
4 = Another kind of water
