Mature Water Flood Analysis (MWFA)

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

Mature Water Flood Analysis is applied on a Reservoirs level.

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

Workflow

1. Upload the required data
2. Completions check
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. Make Cross sections
9. Calculate Blocks Enhancement List
10. Create Action List
11. Execute

Repeat steps 6-7-8-9-10-11 routinely (monthly, quarterly, half year).

1. Data Required

• Create Fields
• Upload Reservoirs
• Upload Wells
• Upload Deviation Surveys
• Upload Perforations
• Upload Well Log Interpretions
• Upload PVT
• Upload Monthly Measures

10. Action List

The typical actions are:

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