Mature Water Flood Analysis is a workflow for identifying the performance gaps in the mature waterfloods performance.

As a result Mature Water Flood Analysis generates Blocks/Patterns Enhancement List.

Upload the required data (see below)
Check production/injection by Completions, define Reservoirs order for analysis
Gridding - Divide the field into patterns/blocks/buckets ("Blocks" below) (Try to put the same grid for all the reservoirs)
Calculate STOIIP for each reservoir using blocks
Match STOIIP to official numbers by changing the edge blocks areas
Make Plots (by field, by reservoir, by block):History, RF vs HCPVinj, RF vs well spacing, WOR vs Np, VRR vs t
Make Maps (by reservoir) showing Blocks: HCPV, HCPVinj, RF, VRR
Calculate Blocks Enhancement List
Draw conclusions

Look through the Completions with commingled Reservoirs production
Decide whether commingled Reservoirs should be groped as an Object for further analysis or treated individually.

This check is valuable when production allocation between the reservoirs is an issue.
