... operations and also for a time period of about 50-60 day later when an adjacent pad was being fractured. PGT was used for every cluster in two stages in the toe side of each well, with each stage having its own unique tracer. Figure 8 provides a graphical representation of the PGT returns. Each curve...

... tracers (6 for oil and 6 for water per well), which allows for in-depth analysis of the AICD performance, and an unprecedented comparison with 2 offset wells. The results from the tracers indicate that the AICD achieved both objectives: equalizing the flux in the reservoir to the well and reducing water...

... Abstract A new and robust tracer technology is introduced based on encapsulated Nano-sized synthetic DNA. This cutting-edge technology enables bonding of synthetic DNA strands with unique sequences to a magnetic core particle and encapsulating them with silica making it possible to have...

... monitoring, fracture modelling, and tracers were employed to evaluate stimulation response between wells. Realtime downhole pressure monitors observed the non-producing upper wellbore, while the lower well produced. Fluid rheology determined viscosity changes for different HVFR loadings, and fracture...

...Statistical analysis of history matching discordances with different reservoir models Abstract Interwell tracers are powerful reservoir surveillance tools that provide direct reservoir flow paths and dynamics, which, when integrated with near real-time production optimization, can greatly...

... Abstract The development of automatable high sensitivity analytical methods for tracer detection has been one of the most central challenges to realize ubiquitous full-field tracer deployment to study reservoirs with many cross-communicating injector and producer wells. Herein we report...

... Abstract Over the past decade, commercially available inflow tracers have been increasingly used to permanently monitor lower completions without the need for intervention. They have been designed to release selectively to oil or water, typically for clean-up verification, inflow quantification...
