Every Oklahoma operator who has held a 160-acre lease for more than a year has the same monthly chore: pull the gauges, reconcile the run tickets, and put the numbers on Form 300R. It is Oklahoma’s monthly gross production report, filed with the Oklahoma Tax Commission and governed by rules that the Oklahoma Corporation Commission (OCC) enforces on the production side.
Form 300R captures oil, gas, and condensate produced each month, broken out by lease and by well type. It feeds the gross production tax calculation and gets used by OCC inspectors when they want to know what a lease actually produced. The form is filed through the Oklahoma Tax Commission’s online system, and operators who fall behind on it quickly learn that the OTC is more patient than the Texas Comptroller but no less thorough.
The form itself is not complicated. What eats Oklahoma operators alive is the data collection feeding it.
What Form 300R Covers
Form 300R is the Gross Production Monthly Tax Report for oil and gas. For each reporting month and each property, Oklahoma operators report:
- Oil and condensate produced (barrels)
- Gas produced (MCF), including casinghead gas
- Tax category: stripper exemption status, enhanced recovery status, reinjection status
- Purchaser and purchaser ID: who bought the oil or gas that left the lease
- Tax due based on current OTC rates for oil and gas, with applicable exemptions
The filing is due on or before the 25th of the second month following production. January production is due by March 25th. Payment of gross production tax rides along with the filing.
Operators with stripper wells (wells averaging 15 barrels per day or less over a 12-month period) qualify for reduced tax rates, but the exemption has to be claimed correctly on the 300R. A misfiled exemption is the fastest way to overpay the OTC, and getting that refund later is painful.
The Data Behind the 300R
The numbers on Form 300R do not show up by magic. They come from the same chain every state reporting form depends on:
- Daily tank gauges: top and bottom on every lease tank, recorded by the pumper.
- Run tickets: signed by pumper and driver, with barrels, BS&W, gravity, and temperature.
- Meter volumes: gas meters for casinghead and produced gas, read at the scheduled interval.
- Downtime documentation: shut-in days, workover days, any reason a well ran less than its usual.
- Purchaser statements: the oil purchaser’s run tickets and the gas purchaser’s monthly statement, reconciled against your field data before the filing.
Every one of those inputs has to be right, and every one has to be on hand by the third week of the month after production. Operators who collect that data on paper, in text messages, or in an Excel sheet the pumper emails once a week usually hit the 25th with at least one lease short of something.
How Pumper Data Rolls Into Form 300R Prep
GreaseBook is where the gauges, run tickets, and meter reads get captured in the field. The pumper takes a reading, and the number is on your screen within the hour. At month-end the data is already totaled per well and per lease, with downtime reasons tagged, purchasers logged, and BS&W tracked against the oil.
That rollup becomes the input for your 300R prep. The actual filing still happens through the Oklahoma Tax Commission portal: the form, the tax calculation, and the payment sit with your accountant or your filer. GreaseBook helps you show up to the filing with numbers you trust instead of numbers you hope are close.
One Oklahoma operator running 28 stripper wells in Stephens County described the change this way: “The 25th used to be a deadline I dreaded. Now the deadline is the 25th because that is when my filer presses submit, not because that is when I am still chasing pumpers.”
If you do not trust the gauges, you do not trust the filing. GreaseBook gives Oklahoma operators real-time pumper data so the 300R prep is a rollup, not a rescue mission.

- Wrong purchaser ID. Every barrel sold has to be tied to a purchaser registered with the OTC. If your pumper wrote down the driver’s name instead of the purchaser, you get to sort that out at month-end.
- Stripper exemption not claimed when it should be. Oklahoma stripper status requires 12-month average production documentation. Operators who never claim the exemption leave real money on the table.
- Produced water volumes skipped. Water is not taxed the way oil and gas are, but the OCC does care about water volumes for environmental and regulatory purposes. Skipping the water line can trigger follow-up from the Commission.
- Casinghead gas treated as lease use. If casinghead is sold, it is reported as sold. If it is used on lease for operations or vented, it is reported differently. Mixing the two creates a discrepancy between your 300R and the purchaser’s statement.
- Late filings compounded by late payments. The OTC charges interest on unpaid gross production tax. A three-month gap turns into a real number fast.
Wrong Fit for This Page
If you are running a Quorum, P2 BOLO, or Enertia stack that already pulls production data from your SCADA and spits out a 300R-ready file, you do not need help with the data collection side. You need help with exemption elections and purchaser reconciliation, which is a different conversation. This page is for the Oklahoma operator running 10 to 150 stripper wells, a pumper on a phone, and a month-end that always feels a week too short.
FAQ
Does GreaseBook replace the OTC or OCC filing software?
No. OCC filing still goes through the OCC’s system. GreaseBook is what captures the gauge, run, and disposition data that feeds 300R: upstream of the filing, not instead of it.
When is Oklahoma Form 300R due?
Form 300R and the associated gross production tax payment are due on or before the 25th of the second month following production. February production is due by April 25th.
Who actually files Form 300R?
The operator of record for each property is responsible for the filing. In practice, many operators hand the 300R off to their accountant or a third-party filer, but legal responsibility stays with the operator.
Where do I file Form 300R?
Form 300R is filed electronically through the Oklahoma Tax Commission’s OkTAP system. The OCC enforces production rules; the OTC collects the tax and processes the filing.
How do I claim the Oklahoma stripper well exemption on 300R?
The stripper well exemption is claimed by reporting qualifying wells under the correct tax code on the 300R. Eligibility requires a 12-month average of 15 barrels per day or less per well. Document the 12-month average in case the OTC asks.

GreaseBook captures what the pumper sees at every tank and every well on a phone, so Oklahoma operators file 300R from a clean rollup. Because the OCC has a long memory for late filers.
