LVF (%)

• SONAR OR Correlation is pipe size dependent

• OR correlation is a function of the LVF and Froude No. OR = f(LVF, Fr)

• Developed after extensive flow loop testing on multiple pipe sizes

• Systematic well testing production allocation and

optimization

• ESP Surveillance / Optimisation

• Pre / post work over testing

• Surface rates during production logging

CASE STUDY – BLACK OIL WELLHEAD SURVEILLANCE

• Initial verification testing performed in conjunction with a test separator for multiple wells

• Historic PVT for reservoir zones provided by client (under-saturated reservoir)

• The offset between SONAR and reference 3-phase rates ranged from +0.1%-15% across various operating conditions (choke sizes, process pressures)

• Verification testing deemed to be successful

• Subsequent field wide surveillance campaigns have been performed over the years
