An effective method to determine and visualize the extent of contact movements within a well.
The impact of intervention (pre vs. post) on well flow characteristics can be readily estimated
using 3-phase inflow calculations.

Last Time Step
• Excellent accuracy of POSEIDONTM’s C-
Track Algorithm vs. simulation.
• C-Track allows to seamlessly assess OWC
and GOC in producing wells
• Log resolution prediction possible

Due to the explicit nature of the saturation function, the ROCM numerical computation is 100x-1000x faster than conventional simulation (seconds vs. minutes or hours)
The inverse problem – finding a saturation distribution that honours material balance and individual well production – becomes solvable within minutes rather than months
