The slimline single-phase reservoir fluid sampler (SLS) is an advanced system for subsurface sampling applications. The SLS is designed to maintain the sample in a 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 the sample carrier (SCAR) with the drillstem test string during well testing. The SCAR-SLS combination enables high-quality pressure-volume-temperature (PVT) samples to be obtained where running wireline is not cost-effective, practical, or safe. By eliminating the need for wireline intervention, the SCAR provides potential rig-time savings of 8 to 24 h during an offshore bottomhole sampling project.
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.
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.
The SLS mercury-free, pressure-compensating bottomhole sampling tool can be operated in configurations of up to ten tools in the SCAR. Applying annulus pressure (the ruptured-disk method) or the IFSM sampler module featuring IRIS Intelligent Remote Implementation System technology allows complete flexibility in sampler activation method.
