Clamp-on sonar surveillance during deliquification increase production by 50%

In Brief
Clamp-on sonar surveillance during deliquification increases production by 50%
Product Line
North and Latin America
  • Work with customer to provide solution to declining gas production on a dry gas reservoir platform, attributed to build-up of liquids within the well bore, whilst undertaking deliquification program – ultimately avoiding production loss because of a build-up
  • To deploy a temporary well test separator to measure the effectiveness of a foam treatment to enhance production – used as an alternative to conventional well test packages which can be more costly
  • Provide the customer with a more cost- effective method of establishing their deliquification process 
Expro Excellence
  • Following track record of successful implementation, Expro Meters identified as providing cost effective surveillance to monitor the effect of customer’s deliquification program
  • Sonar meter clamped-on to temporary pipework on the inlet of the test separator; results could be compared directly with the results from the gas leg of the separator
  • Sonar meter also installed on production piping to provide a measurement of well production, without restriction of the well test package
  • Mobilised quickly: specialist technician and equipment onsite within one day of initial request
  • Well test quality surveillance of produced gas rates conducted by a single field service technician, capable of being deployed with equipment via helicopter 
Value to client
  • Convenient and cost effective means of quantifying the effectiveness of well deliquification than conventional well test separators
  • Four wells tested, each operating over multiple flow rates
  • Real-time gas flow rates from the moment the well was opened up and throughout the evaluation period
  • Gas rates provided by the sonar meters were within 5% of the gas rates reported from the test separator
  • Over 50% increase in production
