Expro is the market leader in optimisation of well test data from the testing of gas condensate wells.  We offer the full range of surface and subsurface testing equipment along with highly experienced personnel. 

We understand that obtaining a representative formation fluid sample and accurate volumetric flow measurements for compositional and PVT analysis is crucial in testing gas condensate reservoirs and have developed the following services in response to this


Expro's SmartVent wet gas flow meters are utilised on applications both offshore and onshore, and are increasingly recognised as effective replacements for test separators and related infrastructure.  Large size, weight and cost savings are realised by installing SmartVent wet gas meters on each of the flow lines.  These systems are a cost-effective alternative to test separators, giving continuous readings of each well's production rates and providing enhanced reservoir management and production optimisation.


The MultiTrace tracer technique can be used on-site to calibrate or verify meter performance under actual conditions.  In combination with SmartVent wet gas venturi meters that monitor the total liquid content of the gas stream, the MultiTrace technique is used to verify the measured production rates and to establish the water/condensate split of the liquid phase.   The overall accuracy and data confidence is greatly improved by this technique and Expro is one of the few companies that offer this service.

IsoSplit® Well-head sampling

Expro offers wellhead multi-phase sampling and metering for gas/volatile oil reservoirs, as well as online wellhead three-stage process simulations, including PVT sampling.

IsoSplit® Separator sampling

The techniques presently used in the oil and gas industry for the recombination of surface samples to obtain representative well stream compositions rely on correct measurement of oil and gas rates. The efficiency of the test separator deteriorates, however, with high gas loads. This is a consequence of the carry-over of dispersed liquid in the gas phase. This carry over is not normally accounted for in the gas/liquid ratio measured for the gas and liquid samples resulting in gas/liquid ratio uncertainty.
