Presidents' Day Closure:
In observance of Presidents' day, the Railroad Commission of Texas will be closed on Monday, February 19, 2018.
Form H-5 Testing Procedure - Instructions
1. Notification/Filing requirements (Instructions 1-3)
- Give 48-hours notice to district office.
- File Form H-5 and attachments in duplicate with the district office within 30-days after any pressure test.
Note that "any pressure test" includes "failed" or "inconclusive" tests.
- Originals will be forwarded to Austin by district office.
2. Pressure Recorder (Instruction 4(a))
- Must use a one-pen recorder to monitor the tubing-casing test pressure.
- Must submit the recording chart if the test is not witnessed by the Commission.
- Test pressure must fall within 30-70% of full scale. Normally, the Commission will allow test pressures to fall within 20-80% of full scale on 1000 psi charts.
- Scale requirements also apply to strip charts.
- Clock for circular chart recorders must not exceed 24 hours.
3. Pressure Gauges (Instruction 4(b))
- Must use gauges to monitor the tubing, casing, and surface casing pressures to be entered under Item 19.
- Casing gauge readings will either back up the recorder or indicate an improperly calibrated instrument.
- Casing pressure must fall within 30-70% of full scale with a minimum increment on the gauge of no more than 5% of the required test pressure.
4. Casing Test Pressure (Instruction 4(c))
- Test to 500 psig or maximum authorized injection pressure, whichever is less, but no less than 200 psig.
|Permitted Maximum Injection Pressure||H-5 Test Pressure|
|200 psig or less
|200 to 500 psig
||permitted maximum pressure
|500 psig or more
- Maintain a 200 psig pressure differential between the test pressure and any tubing pressure. The tubing pressure may be 200 psi higher or lower than the test pressure.
- Wells that inject down casing must test at the maximum permitted pressure.
5. Test Duration (Instruction 4(d)).
Direct questions or comments to: Technical Permitting, 512-463-6792
- Minimum 30-minute test.
- A successful test is one in which the pressure stabilizes within 10% of the required test pressure and remains stabilized for a minimum of 30 minutes.
- Minimum 60-minute test is required for a gas injection well being tested with a gas-filled annulus.
|NOTE: Wells permitted to inject liquids must be tested with a liquid-filled annulus unless otherwise approved by the Commission.
