DOF - Digital Oil Field

Online Field Management Workflow Platform

Overview

The industry has moved in the direction of fully integrated field studies with the objectives of improving field management - production and recovery - over the life of a field. Through this, improved investment decisions can be made by integrating reservoir, production, process and facilities studies as well as economics and field maintenance models.

Petroleum Experts (Petex) has pioneered this direction with the IPM suite, which is the only fully integrated reservoir, well, surface network modelling and production optimisation system in the market today. It relies on sound engineering models at each level in the system. Petroleum Experts made a strategic decision to move this integrated field studies concept forward and to develop real time "IPM Field Management", integrating the field modelling tools with online Surveillance monitoring, Automation and client field and business management Workflows. IFM was commercialised in 2006 and has the largest growth and corporate deployment across the oil industry today.

Project Key Objectives

Develop a NEW on-line integrated production management, engineering and operations support system, tailored to meet the needs of current PETEX clients
Use IPM as the modelling, optimisation and diagnostics engine of the production system
Use an open-architecture to easily plug into user existing databases, SCADA and other best in class applications
Deliver on-line production expert systems with off-line or on-line advisory systems for production environments, models auditing and tracking, including user privilege and ownership control of production models in a central database
Integrated Field and Operational Management centred on IPM - Models

Overall Benefits to Our Clients

Improve production engineering productivity
Improve overall field management
Faster response due to early problem detection (hours versus days)
Focus on exceptions rather than bulk and massive troubleshooting
Use a unified set of published models for process analysis, forecasting and control
Scenario based process optimisation
Zero-Latency application assisted decision making
Applications are fed from field data and are able to send commands to the field and recommendations to Engineers and Operators
Have up to date field models throughout field life

Summary of System Approach

"IPM Engineering Model" - Centric Architecture
Field data quality is screened for consistency and accuracy, using the models and embedded expert system rules, before they are used within the system.
Production System modelling and on-line optimisation runs with set point downloading to field controllers
On-line analysis and quality control of field production tests and real time data
On-line system for the scheduling, optimisation, execution and control of fields
Advanced Logic, based on physics, to detect patterns in field data that can be related with abnormal conditions
