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 order for analysis
  3. Gridding - Divide the field into patterns/blocks/buckets ("Blocks" below) (Try to put the same grid for all the reservoirs)
  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. Check Completions

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