Chapter Operations

1. Critical flow should be maintained across the choke if possible.

2. The well should be opened on a small (e.g. 16/64") choke and then beaned up no faster than 4/64" every 5 minutes, to a moderate choke size of about 28/64" depending on well conditions, then changed to a fixed choke. The cushion should then be unloaded and the well monitored for sand production, checks on equipment integrity should take place, prior to beaning up further.

3. The well should be shut-in at the tester valve first then at the choke manifold.

4. The separator flowmeters should be calibrated prior to the test.

5. For offshore tests the weather forecast (including wind direction) should be checked prior to igniting the flare to ensure that the flow is directed to the correct side of the rig. A good weather window is particularly important for operations from floating vessels, to ensure that the test can be carried out with the minimum of interruption.

6. Prior to flaring, the relevant authorities shall be informed of the impending flaring operations.

7. Portable air compressors must always be used for the oil burners where fitted. The rig air system must not be used under any circumstances.
