Successful Implementations of Enterprise-Scale Solutions for Detecting Well Anomalies and Their Impact on Operational Performance

Innovative Web Design and Creative Solutions

This project successfully delivered an AI-powered Virtual Flowmeter (VFM) solution that provides continuous estimation of oil, gas, and water production rates using time-series machine learning models. The system leverages structured production and telemetry data sourced from Excel-based datasets and applies deep learning techniques to model complex, nonlinear well behavior.

By reducing dependency on physical flowmeters and periodic well testing, the VFM enabled reliable, confidence-aware production estimation at scale. The solution improved production visibility, reduced manual calibration effort, and established a scalable foundation for enterprise-wide deployment and future optimization initiatives.

Business Problem

Accurate production measurement is critical for effective well surveillance and
operational decision-making. However, traditional approaches rely on:
  • Physical flowmeters with high installation and maintenance costs
  • Manual calibration and analysis that does not scale
  • Periodic well testing with limited temporal resolution
  • Fragmented Excel-based data used primarily for retrospective analysis
  • With an initial deployment of approximately 900 wells and a roadmap to exceed 15,000 wells, the organization required a scalable, predictive, and AI-driven alternative

Project Objectives

The engagement focused on delivering a production-ready virtual metering capability with the following objectives:

  • Predict well-level oil, gas, and water flow rates using AI models
  • Provide confidence-aware predictions suitable for operational use
  • Adapt dynamically to changing well behavior and operating conditions
  • Minimize manual calibration and intervention
  • Enable scalable model training, validation, and deployment
  • Deliver outputs suitable for visualization and decision support
  • All objectives were achieved as part of the completed solution.

Solution Overview

The Virtual Flowmeter was implemented as a machine learning–based time-series modeling system that estimates production rates using historical and near-real-time Telemetry data.

The solution applies feature engineering, temporal modeling, and deep learning to capture production dynamics and generate continuous estimates for oil, gas, and water Streams.

Time-Series Modeling Approach

Data Ingestion & Feature Engineering Structured production and telemetry data ingested from Excel datasets Time-series features engineered, including:

  • Lag variables
  • Rolling statistics
  • Trend indicators
  • Derived production metrics
These features enabled the models to learn both short-term dynamics and long-term production trends.

Modeling Techniques

The solution employed deep learning models optimized for nonlinear temporal behavior:
  • Long Short-Term Memory (LSTM) networks to capture sequential dependencies
  • Artificial Neural Networks (ANN) for nonlinear regression patterns Models were trained and validated per well or well group, enabling accurate estimation across varying operating conditions.

Prediction Outputs and Validation

The system generated continuous predictions for:
  • Oil rate
  • Gas rate
  • Water rate
Predictions were:
  • Evaluated against historical measurements
  • Compared across wells and time periods
  • Visualized to support engineering validation and trust
The inclusion of confidence-aware outputs improved usability for operational decision-Making.
