Expro carried out a pilotcampaign to showcase thecapabilities of the sonarflow measurementtechnology in wet gasmultiphase application anddemonstrated how this costeffective solution can beused in areas/applicationswhere traditional productiontesting is not suitable ordifficult to achieve.

Objectives/background

• The client wanted to find an efficientmeans of testing their wet gas wells onan individual basis, while the wellscontinued on normal production, avoidingreliance on diverting the wells to a fixedtest separator (located 13km away)

Expro Excellence

• Expro mobilised ActiveSONAR™measurement technology along withspecialist field technicians to test multipleindividual wells (2 x 10” wet gasproduction wells), downstream of theproduction choke, on a 72-hour rotations

• Data was collected and reported in real-time to the client on-site using Expro’sTotal Production Surveillance Software™(TPS1000)

• After the pilot was complete, collecteddata was compared to the reference dataprovided by the test separator, which wasoperated simultaneously on the samewells – the sonar data was found to be+/- 5% of the test separator data acrossall phases (gas, condensate and water)

Value to client• The small footprint, hand-carried

metering equipment allowed the client totest wells before separation

• Non-intrusive – can be fitted to existingpipework

• Real-time multiphase reporting

• Rates reported within 5% of the testseparator results

• Increased data collection and testingfrequency

• Rapid mobilisation
