The key parameters in water flood planning are permeability and formation thickness which define both water front propagation and pressure support.
The fluid flow in low permeability carbonate reservoirs is often happening through micro-fractures which are difficult to capture with cores and when captured are not abundant in statistics and usually not representative for porosity correlation. This leads to difficulties in modelling, forecasting and specifically water-flood planning.
Pressure interference testing is well known approach to capture cross-well permeability and thickness in-situ. But usual well testing procedures require shutting down receiving wells which is punishing for production targets. This well known problem may be addressed with high resolution quartz gauges and pulse-code decomposition mathematics which allow receiving wells to produce normally while recording the pressure data and then decipher the response from a generating well.
