Brief

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

Mature Water Flood Analysis is applied to the Reservoirs and uses Daily Measures/Monthly Measures for production/injection data.

MWFA

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

Block Enhancement List

The goal of the waterflooding

The goal of the water flooding is to inject the least possible water to produce the most possible oil in the shortest possible time.

Workflow

  1. Upload the required data
  2. Gridding - Divide the field into Blocks/Patterns using the Bubble map by identifying dominant no-flow boundaries. No-flow boundary is a line in the reservoir where reservoir fluids do not cross. Oil and water on either side of the line flow away from this line.
  3. Calculate the well allocation factors WAF for blocks/patterns.
  4. Calculate each block/pattern cumulative fluids production and injection volumes. Number of active producers and injectors. Current and total well stock.
  5. Calculate HCPV from the blocks/patterns areas and Well Log Interpretation summaries
  6. Match total HCPV to the STOIIP numbers by changing the edge Blocks areas
  7. Calculate waterflood performance indicators: HCPVinj, RF, VRR, VRRcum
  8. Make Plots (by field, by reservoir, by block): History, RF vs HCPVinj, RF vs well spacing, WOR vs Np, VRR vs t
  9. Make Maps (by reservoir) showing Blocks: HCPV, HCPVinj, RF, VRR
  10. Make Cross sections
  11. Calculate Blocks Enhancement List
  12. Create Action List
  13. Execute


Repeat steps 5-6-7-8-9-10 routinely (monthly, quarterly, half year).

Data Required

Action List

The typical actions are:

  • Convert producing well to injector
  • Shut in inefficient injection well, water-cyclers
  • Increase/Decrease well injection rate
  • Add/squeeze Perforations at producing or injection wells
  • Drill infill production/injection well
