Subsea Sampling Systems MARS Multiple Application Reinjection System Configurations

Subsea Sampling Systems MARS multiple application reinjection system configurations

APPLICATIONS Almost all technical and economic studies in the oil industry require an understanding of the reservoir ■■ Production monitoring fluids. MARS* multiple application reinjection system sampling technology enables the capture of ■■ Reservoir modeling and management a representative, uncontaminated sample from multiphase flow, in which the sample has the same molecules in the same proportions as the flow at the sampling point where all three phases are ■■ Flow assurance in equilibrium. ■■ Well intervention ■■ Each phase is enriched and captured individually to collect sufficient volume of sample from ■■ Subsea processing strategically chosen phase-rich sampling points. ■■ EOR ■■ No pressure or temperature drop should occur during sampling to maintain equilibrium BENEFITS between phases. ■■ Enables representative subsea sampling ■■ Each phase is captured and physically or mathematically recombined for reservoir fluids properties. throughout life of field ■■ Mitigates risk and enhances flow assurance management ■■ Optimizes multiphase flowmeter calibration and performance ■■ Increases production and recovery rates ■■ Reduces capex

FEATURES ■■ Flexibility for integration into subsea hardware and for various sampling applications ■■ Three-phase representative sampling from multiple wells in a single dive ■■ Phase detection and enrichment ■■ Complete chain of custody throughout sample journey ■■ Proven technology ■■ Ideal solution for greenfield architecture ■■ Retrofit capability for brownfield applications
