== 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.

[[File:MWFA.png|800px|MWFA]]

As a result [[Mature Water Flood Analysis]] generates [[Block]]s/[[Pattern]]s [[:Category:Enhancement List | 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==
#Upload the required data
#Gridding - Divide the field into [[Pattern]]s/[[Block]]s/[[Bucket]]s 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.
#Calculate well allocation factors, [[WAF]], for blocks\patterns.
#Calculate [[HCPV]], [[HCPVinj]], RF, VRR, VRRcum for each reservoir using blocks
#Match total [[HCPV]] to [[STOIIP]] numbers by changing the edge [[Block]]s 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
#Make Cross sections
#Calculate Blocks Enhancement List
#Create Action List
#Execute


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

=== Data Required===
*Create [[Field]]s
*Upload [[Reservoirs]]
*Upload [[PVT]]
*[[Upload Wells]]
*Upload [[Deviation Survey]]s
*Upload [[Perforations]]
*Upload [[Well Log Interpretation]]s
*Upload [[Monthly Measures]]

=== 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
