OK… I’ll expand a bit.
1) OCC will have gas numbers listed for wells classified as GAS wells. Production numbers will be about 4-5 months behind production http://occpermit.com/wellbrowse/
2) The OTC will have oil and gas numbers. They are usually about 5-6 months behind production and only seem to show about 15 months back. https://www4.oktax.onenet.net/GrossProduction/index.php
Note: OTC and OCC will not report the exact same gas data. OCC is report allowances of gas pulled from the reservoir and OTC is reporting sales. Gas may be vented/flared, used in the production/transportation process, or otherwise lost.
3) You can submit a list of wells to the OTC and they will pull the data for a fee. This will have history, but I don’t believe you will get any data newer than what is online.
4) There are commercial industry databases with production data. 95% (or more) of the Oklahoma data they are reporting comes from the OCC or the OTC (Oklahoma Tax Commission). Pangaea, Drilling Info, and IHS are the biggest. Yearly cost for Oklahoma data about 1500, 2000, and way more for IHS but they do offer an a la carte pricing. It will run about $5-$10 per well and a minimum of $20 per month that it is used.

5) There are Oil Production reports submitted that are published by the OCC. You have to search the imaged documents from the reporting party which is usually the purchaser. Then you have to search by PUN, the Production Unit Number. These reports will be between 45-90 days after the production month reported. You have to get creative to find the purchaser to tie in with the well sometimes.

6) The paystubs you get on a well will be the most accurate and usually quickest available except when you are talking about a newly producing well that has not paid out yet.
7) Taking a working interest in the well will give you access to daily reports.
8) Pay a petroleum engineer, consultant, or mineral manager to retrieve the data. But be aware as they will have the same limitations as outlined above.
The PUN on this well is 119-213302-0-0000 and I would guess Phillips is the purchaser. I don’t see any oil production on the April report.
You are way too premature trying to gather numbers to determine the well performance or decline curve. Since you won’t have any root causes for any changes in production, you really won’t have anything to judge accurately.
