Does OSHA require electronic 300-log submission for oilfield companies?
For oil and gas extraction establishments with 100 or more employees, yes. Full Form 300 and 301 case detail goes to OSHA every year, due March 2.
Answered in short
5 things that decide this
- 01OSHA requires establishments with 100 or more employees in listed high-hazard industries to file Form 300 and 301 case detail electronically each year. Oil and gas extraction, NAICS 2111, is on that list in Appendix B of the recordkeeping standard.
- 02Filings go through OSHA's Injury Tracking Application (ITA). They are due March 2 for the prior calendar year, so the March 2, 2026 filing covered 2025 data.
- 03Smaller sites aren't off the hook. At 20 to 249 employees in a listed industry, the Form 300A summary still goes in each year, even where full case detail is not required.
- 04The thresholds count employees per establishment, not per company. An operator spread across yards and districts has to check each site.
- 05Companies keeping 300 logs on paper spend February rebuilding a year of incidents from site files. The filing is only painless when the log is electronic all year.
Who must submit what, and when
Electronic submission runs on two thresholds. At 100 or more employees in an Appendix B industry, which includes oil and gas extraction under NAICS 2111, an establishment files its full Form 300 log and Form 301 detail each year. At 20 to 249 employees in a listed industry, it files the Form 300A summary. Everything goes through the Injury Tracking Application by March 2.
Which bucket you fall in depends on your NAICS code and your size, and both are easy to get wrong. Oilfield service companies often carry other codes, since drilling and support work is classed separately. Size is counted per establishment at its peak for the year, part-time and seasonal workers included.
A missed filing is a citable violation. OSHA has also published site-level injury data from these filings. For many operators the sharper risk is a customer's safety review reading a bad year off a public record.
Why the March 2 filing hurts paper-based operators
The submission itself is a data upload. What hurts is assembling it. A year of incidents spread across paper JSAs, clipboard forms and site files has to become clean case records: classification, day counts, narrative. Crews that log incidents digitally all year export and file. Everyone else spends February reconstructing.
Field data capture is a solved engineering problem in this industry. TankAware, a petroleum-site platform we built, replaced paper inspection logs across hundreds of fuel sites. Compliance prep there fell from four weeks to two hours. An injury log is the same shape. Capture at the moment of the event, classify once, and March 2 becomes an export instead of a project.
A capture layer like that earns its keep elsewhere too. Your field ticket, JSA and incident report can ride the same phones and the same sync. It plugs into whatever dispatch or EHS tooling you already run, or stands alone where nothing does.
- Incident in the fieldCaptured on the phone, same day.
- 300 log entryClassified once, not re-keyed.
- 301 detailNarrative and case facts attached.
- Year closesLog already complete.
- March 2Export, upload to the ITA, done.
The deadline is annual. The work is daily, and that is the design decision.
Related questions
01Do oilfield service companies fall under the 100-employee rule?+
Only when the establishment's NAICS code is on the designated list. Oil and gas extraction, NAICS 2111, is on it. Drilling contractors and support-activity companies carry different codes. Check each establishment's code against Appendix A and Appendix B rather than assuming either way.
02What exactly gets submitted from Forms 300 and 301?+
Case-level detail: the log entries from Form 300 and the incident facts from Form 301, uploaded through the ITA. The Form 300A summary goes in with them. OSHA's process omits certain identifying fields from the case data.
03Is the 300A summary still required if we file full case detail?+
Yes. Designated establishments submit the Form 300A summary along with their 300 and 301 data. The summary requirement also reaches the wider 20-to-249 employee group that never owes case detail.
