Mature Water Flood Analysis

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 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

Data Upload

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