Texas Form H-10: the annual disposal and injection well report

Texas disposal and injection well operators monitor pressure and volume every month and report it once a year on Form H-10. The catch is that the due date isn't the same for everyone. Here's how it works.

Monitor monthly, report yearly

Operators of disposal and injection wells must monitor injection pressure and volume at least monthly and report the results once a year on Form H-10. The monitoring records have to be kept for at least five years. A newly permitted well that hasn't been drilled yet still needs an annual H-10.

Finding your due date

H-10 isn't due on one statewide date. Each field has a filing cycle, and your well's due date comes from it. You can look it up with the RRC's online H-10 Query under "Filing Cycles by Field". The RRC sends a courtesy letter and posts the blank form online about three and a half months before the due date, and the form has to be received by the date printed on it.

What the form asks for

Injection pressure: the average and maximum for each month of the reporting cycle.
Injection volume: the total liquid and/or gas injected each month, at standard temperature and pressure. If the well didn't inject, you mark that there's no volume to report.
Annulus pressure: the minimum and maximum pressure between tubing and casing each month and the number of readings ("C" for continuous monitoring). It's optional unless your permit requires it, and in some cases can serve as an alternative way to show mechanical integrity.
Injection interval and tubing/packer depth.
Fluid types: each type injected as a whole-number percentage of the total, adding to 100%. Ordinary produced water and other exempt oilfield waste goes under "Other Non-Hazardous Oil & Gas Waste".

What happens if it's late

If the H-10 isn't filed, the RRC sends a second notice 30 days after the due date. If the operator hasn't contacted the RRC's Technical Permitting staff 30 days after that, enforcement begins: a well with no production on the lease is sealed, and a lease with production has its pipeline connection severed.

Step by step

Look up each well's cycle in the H-10 Query and put the due date on your calendar.
Record readings every month: injection pressure (so you have each month's average and maximum), volume injected, and annulus pressure if your permit calls for it.
Track what you inject so you can give fluid-type percentages at year end.
File online through your RRC Online System account before the due date on the form.
Keep the records for at least five years.

How WellCollar handles it

H-10 data kept every month, with a reminder before it's due

WellCollar's disposal module keeps the monthly injection volumes and pressures Form H-10 asks for, and puts each well's H-10 due date on your filing calendar with reminders, so the year-end report is a lookup instead of a hunt.

Questions

Common questions

When is Texas Form H-10 due?

Once a year on a date set by your field's filing cycle. Look it up with the RRC's H-10 Query under Filing Cycles by Field; the RRC sends a courtesy letter about 3.5 months ahead.

How often do I have to monitor a Texas disposal well?

Injection pressure and volume must be monitored at least monthly, with records kept for at least five years.

Is annulus pressure required on Form H-10?

Only if your permit requires it. Otherwise it's optional, and in some cases it can serve as an alternative mechanical integrity demonstration.

What happens if I don't file Form H-10?

The RRC sends a second notice 30 days after the due date. If you haven't contacted Technical Permitting 30 days after that, a well with no on-lease production is sealed, and a producing lease has its pipeline connection severed.
