Overview

A SONG webinar with a technical presentation by the Technical Professional team from PETRONAS.

This talk describes the debottlenecking of the highly integrated and complex offshore system by a holistic network modeling approach without compromising operating envelope, facilities constraints, and product specifications by optimization of hydrocarbon evacuation route for the offshore field, thereby monetizing upstream field development.

For complex network containing more than 80 gas fields, 100s export pipelines, multiple hubs, gas highways and receiving terminals, with varying degree of ullages and variations in the level of gas acceptance level, is very challenging to optimize evacuation path for new hydrocarbon, as it may potentially contain uncertainties in terms performance of reservoir fluid quality, parameters such as pressure\temperature, flow and condensate value potentially causing impending risks of violating existing network operating limitations as capacity, pressure imbalance, resultant specifications violations. These uncertainties in the evacuation path may result in (a) concerns for system operability (b) vague results of product specifications can pose a threat in designing a production plant and facilities improvement requirements as well as firming up investment decisions for offshore development and onshore facilities.

It is essential to perform situational analysis for the network to arrive at required debottlenecking for strategizing an optimal evacuation for a new offshore development tying-in to existing infrastructure. A new approach developed by building a highly integrated steady-state network model in a single simulation platform for the complex offshore network (end to end value chain) in industrially available software to perform situational analysis. The model was validated and deployed for evaluation of multiple scenarios as alternate evacuation options considering system ullage, pipeline hydraulics (adhering to first principles), honoring gas specifications, and facility constraints. Sectionalization of the sweet and sour gas corridor was performed and analyzed for multiple tie-in options for its outcome on the overall network. It was assured that system parameter as pressure, velocity, specifications for selected scenarios are always within the operating envelope.

It was demonstrated that the integrated model could optimize the best evacuation route in terms of technical and business requirements & has resulted in the monetization of new offshore development. Impediments across the network were forecasted as an outcome from model and its mitigations such as debottlenecking, change in operating strategies, evacuation path alternations, modifications in the network, planned much in advance, and implemented accordingly.

The novelty of this concept is the ability to arrive at an optimized hydrocarbon evacuation route within the existing network by means of minimal debottlenecking to the existing system. This output from the simulation could avoid the inclusion of an additional dedicated facility that leads to huge CAPEX optimization.
