Expro offers a complete range of cased hole reservoir fluid sampling options. Our sampling tools and sample bottles are designed to cope with the extremes of pressure, temperature and the corrosive fluids encountered in deep, sour wells.

Our non-corrosive sample carriers, single phase bottom hole samplers and surface sampling equipment is state of the art and designed to ensure that representative reservoir fluid samples are obtained. Our PVT experts liaise with the sampling teams to ensure that optimum samples are obtained.

Expro offers unique sampling capability – particularly for gas condensate systems, where conventional sampling and measurement techniques can leave a high degree of condensate/gas ratio uncertainty, increasing the potential for incorrect characterisation of the reservoir fluid.

Our ‘split stream’ well head testing method supplies independent CGR data together with the necessary compositional and phase equilibrium data for feasibility studies and designs for production and transportation of oil and gas.

Well stream analysis is carried out together with practical simulations of processing operations. The testing equipment consists of a test manifold for multiphase sampling and a laboratory allowing three-step separation followed by hydrocarbon evaluation. Our testing equipment is also suitable for various plant performance tests.

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.

PVT Separator Sampling

Expro offers separator PVT sampling as part of the total sampling package. This type of separator sampling is aimed at recreating the reservoir fluid composition by recombining gas and liquid samples using the separator pressure, temperature gas/liquid ratio to determine the amount of gas and liquids going in to the mixture.
