OILFIELD WATER MANAGEMENT

摘要

A method for managing oilfield water. Oilfield water data is grouped into discrete and non-overlapping groups. Outliers are removed from the data. Features of the remaining data are analyzed to identify most discriminative feature. The data is separated into training data and testing data, and the training data is fit into a model that shows the best precision, accuracy and recall. The model is confirmed using the testing data. Upon confirmation of the accuracy of the model, the model is applied to data for a new proposed oilfield well, and a new proposed project is implemented or disapproved based on a result of the identified model that predicts water production of the new proposed oilfield well.

1. A method for managing oilfield water, comprising:
obtaining oilfield water data for a plurality of oilfield wells; grouping the oilfield water data into a plurality of discrete and non-overlapping groups; identifying and excluding at least one outlier data from the grouped oilfield water data groups to produce non-excluded oilfield water data; analyzing a plurality of features of the oilfield water data in the non-excluded oilfield water data to identify at least one most discriminative feature of the plurality of features; separating data of the identified at least one most discriminative feature of the oilfield water into training data and testing data; fitting a classification model to the training data iteratively using a grid search function to identify a model among a plurality of models that model the data with best precision, accuracy and recall among the plurality of models; running the identified model on the testing data to confirm accuracy of the identified model in estimating and predicting oilfield water production of a new proposed oilfield well or an existing oilfield well, wherein, upon confirming accuracy of the identified model, the identified model is applied to implement a new proposed oilfield well drilling operation or implement an existing oilfield well operation.
