Flooding Control technology

Using machine learning methods

FC
Challenges addressed by FC in the development of mature fields
#1

Suboptimal efficiency coefficient of the injected water unit

#2

Suboptimal efficiency coefficient of the produced liquid unit

#3

Lack of real-time processing of large volumes of unstructured data

#4

High number of labor-intensive routine operations

#5

Lack of a tool for forming injection well modes considering interference

#6

Lack of a unified methodology for optimizing injection with mutual influence of several wells and water influx risks

Capabilities of the FC system

Automatic formation of areas with maximum hydrodynamic connectivity between wells, including producing ones

Calculation of optimal injection modes with any limitation scenario

Reduction of unproductive injection volumes without loss of oil production

A separate neural network is created and trained for each area, taking its features into account

A hybrid function for minimizing water cut and maximizing oil production is used when searching for optimal modes

Optimal redistribution of current injection with increased oil production

Algorithm operation scheme
Prepared data

Filtering and restoring data
