Slimline Single-Phase Reservoir Sampler

Overview Library

Retrieve fluid samples in single-phase condition for reservoir-representative results

The slimline single-phase reservoir fluid sampler (SLS) is an advanced HPHT-rated subsurface sampling system that ensures 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.

Complementary combination saves time

The SLS is run in SCAR inline independent reservoir fluid sampling operations with the downhole test string during well testing. The combination enables obtaining high-quality PVT samples in operations where running wireline is not cost-effective, practical, or safe. 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 allows controlled, uncontaminated reservoir sampling without sample flashing. The unaltered sample is retrieved at the surface in single-phase state, requiring no recombination before transfer. Because samples need not be recombined, the sample transfer takes minutes instead of hours. Up to 10 SLS tools can be operated in the SCAR sampling system.

Field-proven, reliable technology

The SLS technology is based on our existing single-phase reservoir sampler (SRS), which has been operated more than 3,500 times. The reliability of the SRS has established it as the benchmark tool for all subsurface sampling operations.
