Mature Water Flood Analysis (MWFA)
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.
Workflow
- Upload the required data (see below)
- Check production/injection by Completions, define Reservoirs and Objects for analysis
- Gridding - Divide the field into patterns/blocks/buckets
- 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
1. Data Upload
- Create Fields
- Upload Wells
- Upload Deviation Surveys
- Upload Perforations
- Upload Well Log Interpretions
- Upload Reservoirs
- Upload PVT
- Upload Monthly Measures
2. Completions Check
- Look through the Completions with commingled Reservoirs production
- Decide whether the commingled Reservoirs should be groped as Objects for the further analysis or treated individually.
This check is valuable when production allocation between the reservoirs is an issue.
