Method and system for real time production management and reservoir characterization

A system for data processing to predict values in a reservoir, comprising a processor and a memory wherein the memory stores a program having instructions for:

• a) receiving input data characterizing the reservoir;
• b) obtaining transient areas:
• i) receiving data from the reservoir;
• ii) transforming the pressure data using discrete wavelet transformation to produce transformed data;
• iii) removing outliers from the transformed data;
• iv) identifying and reducing noise from in the transformed data;
• v) detecting transient areas in the transformed data;
• c) producing a computer model in response to said input data including performing history matching on detected transient areas;
• d) verifying the computer model through history matching and determining predictive values of the reservoir;
• and
• e) outputting predictive values.

A computer readable medium storing computer instructions which when executed by a computer, enables a computer to predict values in a reservoir the computer instructions comprising:

• a) receiving input data characterizing the reservoir;
• b) obtaining transient areas by;
• i) receiving data from the reservoir;
• ii) transforming the pressure data using discrete wavelet transformation to produce transformed data;
• iii) removing outliers from the transformed data
• iv) identifying and reducing noise from in the transformed data;
• v) detecting transient areas in the transformed data;
• c) producing a computer model in response to said input data including performing history matching on detected transient areas;
• d) verifying the computer model through history matching and determining predictive values of the reservoir;
• and
• e) using predictive values.
