Overview

Integrated process operations and production optimization are highly focused on the petroleum industry worldwide. A significant growth in the oil industry is monitoring the integrated process by using a single modelling and optimizing platform. This talk will introduce iCON, PETRONAS’s own process simulation software which is used to predict the optimum pressure set points for separator trains, optimum individual choke valve opening and ways to maximize production with the existing installation.

A study was performed on a topside processing facility and its production wells with an objective to maximize the liquid and gas production rate without exceeding the constraints in the processing trains. The source code developed was used to generate a flow equation for each well to get the final composition to the iCON model. From the current operating condition, various case studies were run to obtain production profiles at different operating pressure with the aim of locating the maximum oil and gas production. The optimum pressure is then iteratively analyzed against the process constraints to locate the optimum set point.

With a single surface and sub-surface modelling platform, seamless data transfer, thermodynamic stability and efficient optimization iteration is ensured. Multi-variable and multiphase Vertical Lift Performance (VLP) curves were generated for each well to cover a wide range of operating envelope to ease the process of implementing the study and locating the CAPEX free implementation region.

The main outcome of this study was the CAPEX free optimization set points. The implementation strategy of this CAPEX free set points was within the operating envelope which yielded immediate value creation. The findings were a great breakthrough since changing separator set points and individual choke valve opening yields in additional oil and gas production without violating any process constraints.

An evening event with technical presentation by the Technical Professional team from Group Technical Solutions, PETRONAS Project Delivery & Technology Division and time for networking over refreshments. Registration from 17:30; the event will commence at 18:00 and close at 20:00.

This event is free and open to all. Bring along your colleagues and introduce them to the Oil & Natural Gas Special Interest Group (SONG) and to IChemE.

Speaker

Shahrul Azman Zainal Abidin is a Custodian Engineer and Group Technical Authority inProcess Simulation and Optimization, working for PETRONAS Group Technical Solutions. He graduated as a Chemical Engineer from California State University, Long Beach, USA in 1998 and received an MSc in Gas Engineering from University of Technology Malaysia in 1996.

He is a Fellow of IChemE and Senior Member of AIChE with twenty-four years of experience in project & engineering management. Besides, he also specializes in process modelling and optimization of oil & gas facilities. Apart from developing PETRONAS’s own process simulation software, iCON, he also developed and patented an Integrated Separation System, Sep-iSYS, that is used for Slug & Sand handling, Inlet Heating and 3 Phase Separation, particularly suited for upstream oil & gas production facilities.
