Practical Engineering were contracted by Weatherford’s drilling team to undertake engineering design, drafting and full manufacture of a first of a kind High Pressure, High Temperature (HPHT) Flare Tank for gas drilling. The design was based around the following parameters:
- Operating pressure capacity: 5,000 psi
- Tank Volume: 12m3
- Gas glow rate: 17.5 mmscfd (Million Standard Cubic Feet per day)
The design integrated a mud/ gas separation vessel discharged directly from the choke manifold via a high pressure (5000psi) panic line. This allows separation of the gas to the flare stack for flaring whilst the mud is retained in the mud storage tank for return to the rig.
Practical Engineering also integrated our own design of flare stack, burner and pilot assembly utilising our Ignition Control and Monitoring System (ICAMS). ICAMS is a low voltage control module powered by a solar panel and battery for stand-alone, remote operation. Operators can now have peace of mind that the flare pilot is being monitored and maintained. If the pilot gas needs changing or a pilot fault occurs, the ICAMS will raise the alarm and place the system in a safe state. Our flare design is certified to AS and API Standards and also for Australian Gas Regulations for Class 1 (non-monitored) burners.
The manufacture of this flare adds the unit to Practical Engineering’s range of “pit-less” flaring tanks, offering minimum possible impact on the environment. The flare system removes any need or expenditure on earthworks, excavating, lining or remediating a flare pit.
Following a successful manufacture phase – Practical Engineering’s project management team assisted with site commissioning of the flare at the rig site in the Cooper Basin
