How to file Ohio's Form 10 annual production report

Every year, owners of Ohio oil and gas wells report the prior year's oil, gas and brine production for each well to the Ohio Department of Natural Resources (ODNR). Here's what the statement asks for and how to get it right the first time.

Who has to file

Ohio law requires the owner of every well that is producing or capable of producing oil or gas to file a statement of production for the prior calendar year. A shut-in well that could produce still counts, so a year with no sales is reported as zeros, not skipped.

Horizontal wells are the exception. They report every quarter instead, due 45 days after each calendar quarter closes, on ODNR's quarterly statement of production (Form 10-H).

What goes on it

The statement reports three volumes for each well for the year:

Oil in barrels. Condensate is reported as oil.
Gas in Mcf (thousand cubic feet). Natural gas liquids are reported as gas.
Brine in barrels: the produced water you hauled or disposed of.

Each well is identified by its 14-digit API number (no dashes), well name and number. ODNR's production forms also ask for days in production, and optionally oil and gas sold, the date of first production, any domestic gas user on the well, and the tanks the well feeds.

Step by step

Start from your own records. Total each well's oil from purchaser run tickets, gas from your gas sales or meter statements, and brine from water-haul tickets. Use your own numbers, not the volumes the state has on file from earlier years.
Split shared tanks. Purchasers report oil by tank, but Form 10 is per well. If several wells feed one tank, divide the hauls between them the same way every time. See splitting production from a shared tank.
List only the wells you owned. Include every well you owned during the year. If a well was plugged or transferred mid-year, have the plugging (Form 55) or transfer (Form 7) date ready, because the form asks about status changes.
Report zeros where they apply. A well capable of producing that made nothing still gets a line with zero volumes.
File by March 31. With more than 100 wells you must file electronically in a format ODNR approves; with fewer, electronic filing is optional. ODNR's production section takes filings at Production@dnr.ohio.gov or by mail to 2045 Morse Road, Building F-2, Columbus, OH 43229-6693. Questions go to (614) 265-6922.
Keep proof it arrived. Save the confirmation or reply from ODNR with your copy of the filing.

Where operators get tripped up

Typing it well by well. With dozens of wells, retyping a year of production into a form is where most errors come from. Build the totals from tickets once and export them.
Mixing up the year. Form 10 is the calendar year, not your fiscal year.
Forgetting brine. Brine is part of the statement, so water-haul tickets need to be totaled per well too.
Including wells you sold. A well you sold before the year started belongs on the new owner's statement, not yours.

How WellCollar handles it

Form 10 for all your wells in one file

WellCollar totals each well's oil, gas and brine for the year from the run tickets, gas sales and water hauls your crew already enters, splits shared tanks evenly, and exports the annual production report for every well as one bulk file instead of typing it well by well. Form 10 shows on your filing calendar with a reminder before March 31.

Questions

Common questions

When is Ohio Form 10 due?

On or before March 31 each year, for the prior calendar year's production (Ohio Revised Code 1509.11).

Do I file Form 10 for a shut-in well?

Yes, if the well is capable of producing. Report it with zero volumes rather than leaving it off.

Do horizontal wells file Form 10?

No. Horizontal wells report quarterly instead, due 45 days after each calendar quarter ends.

Do I have to file Form 10 electronically?

Owners with more than 100 wells in Ohio must file electronically. Owners with fewer wells may file electronically or on paper.
