Mature Water Flood Analysis (MWFA)

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

MWFA

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

Block Enhancement List

Workflow

  1. Upload the required data (see below)
  2. Check production/injection by Completions, define Reservoirs and Objects for analysis
  3. Gridding - Divide the field into Patterns/Blocks/Buckets
  4. Calculate STOIIP for each reservoir using blocks
  5. Match STOIIP to official numbers by changing the edge Blocks areas
  6. Make Plots (by field, by reservoir, by block):History, RF vs HCPVinj, RF vs well spacing, WOR vs Np, VRR vs t
  7. Make Maps (by reservoir) showing Blocks: HCPV, HCPVinj, RF, VRR
  8. Calculate Blocks Enhancement List
  9. Draw conclusions


1. Data Upload


2. Completions Check

  • Look through the Completions with the commingled Reservoirs production
  • Decide whether the commingled Reservoirs should be grouped as Objects for the further analysis or treated individually.

This check is valuable when production/injection allocation between the Reservoirs is an issue.

9. Conclusions

The typical actions are:

  • Convert producing well to injector
  • Increase/Decrease injection rate
  • Add/squeeze Perforations
  • Drill additional production/injection well
