Inline independent reservoir fluid sampling
Obtain single-phase, reservoir-representative PVT samples while reducing rig time and risks with independent nitrogen-charged samplers.
The slimline single-phase reservoir fluid sampler (SLS) is an advanced HPHT-rated subsurface sampling system that ensures that the sample remains in single-phase condition and above reservoir pressure as the tool is retrieved from the well. Single-phase technology provides truly representative samples and is essential for measurements requiring samples in unaltered conditions, such as pressurized pH measurements in formation water or asphaltene deposition analysis in oil.
The SLS is run in SCAR inline independent reservoir fluid sampling operations with the downhole test string during well testing. This combination obtains high-quality PVT samples in operations where running wireline is not cost-effective or practical. Up to 10 SLS tools can be operated in the SCAR sampling system. By eliminating the need for wireline intervention, SCAR sampling provides potential rig-time savings of 8 to 24 h during an offshore bottomhole sampling project.
The SLS enables controlled, uncontaminated reservoir sampling without sample flashing. The unaltered sample is retrieved at surface in single-phase state, requiring no recombination before transfer. Because recombination is eliminated, sample transfer takes minutes instead of hours.
