Continuous Reservoir Surveillance

Up to 10 years of continuous reservoir monitoring without the risk and cost of well intervention.



Zonal Inflow Quantification

Water & Gas Breakthrough Detection

Zonal Production Trend Monitoring

Repeatable measurements, on-demand information

Information from each zone is produced continuously during the multi-year life of the Intelligent Tracers, enabling on-demand and repeatable measurements without risky interventions or expensive changes to well design. 


Continuous Reservoir Monitoring

Intelligent Tracers enable trend analysis to identify changes in oil/water inflow in each zone of the well to support operational decision-making and to optimize production at different time scales.

RESMAN provides an important piece of the “reservoir puzzle”, enabling enhanced asset management and production optimization.

By providing zonal resolution to the well, Intelligent Tracers increase the resolution of the digital oilfield model. Well events – such as change in drawdown, changes in skin, water or gas breakthrough and clean-up – can be assessed using inflow tracers for continuous monitoring.

This way of digitizing the wellbore unlocks zone-specific digital data-streams, enables improved reservoir surveillance, and supports short, mid and long-term decisions:

  • Short-term: The identification of production losses/gains (zone-specific drawdown requirements for fluid-specific inflow operation) and an improved productivity index (zones to be targeted for selective solvent injection (e.g. in the case of asphaltene deposition)).
  • Mid-term: Improving productivity index and reduced lifting costs (zones to be targeted for selective water shut-off, selective stimulation and/or re-stimulation) and other targeted well interventions.
  • Long-term: Improved forecasting, reservoir development planning and reduced uncertainty (refined and better predictive reservoir models due to reduced subsurface uncertainty) and improved production (zones to be targeted for future water injection or future infill drilling).

These decisions have a direct impact on the inflow performance curve (IPR) and on the vertical lift performance curve (VLP) highlighting the interrelation between continuous monitoring from tracer systems, nodal analysis and production optimization.
