Supply Chain Planning (PETRO)

The challenge to maximize enterprise value from integrated supply, refining, distribution, and marketing systems is multi-faceted. On an ongoing basis, it involves decisions such as:

Which crude oils to buy for the refinery?
Which products (gasoline, jet fuel, diesel, lubricants, fuel oil) to manufacture?
How to operate the refinery to make the best use of our assets?

Crude optionality, refinery capability, and market price volatility create an ongoing optimization opportunity in the crude-to-customer supply chain. Finding the best fit between crude oil, refinery capability and product supply is crucial to increase efficiency in value chain activities and ultimately, delivering products to consumers.

PETRO, a refinery linear programming optimization system developed by Chevron, enables users to make informed decisions on optimizing refinery processes, from raw material selection to final production.

Features

It has the following features:

Robust, fast solution: Find a solution quickly using superior recursion implementation and modeling techniques
Outstanding case management: Allow planners to expand the operating envelope and investigate more options
Reduced support requirement: Utilize unique features to minimize problems caused by inadvertent changes to the model

Data-driven analytical approach

PETRO is built on data, and the quality of such data is key to its accuracy and value. By leveraging the underlying models for analysis and automatic dynamic updates, users can operate more effectively and focus on higher-value activities.

Underlying models: Create, update and analyze yield and distillation models using crude oil data, refinery data and processing unit models
Dynamic inputs: Automatically load market data such as demand forecasts, price forecasts and feedstock availability

One common model of the refinery can be used to do strategic analysis, translate it to business planning and then to monthly planning through the revision of dynamic inputs.

An Integrated Planning Example: Petro-SIM and PETRO

Yokogawa and KBC process simulation software Petro-SIM^® uses rigorous simulation models to manage facility processes over a wide operating window, and is used to optimize facility performance and organizational productivity. Petro-SIM reflects real-time information of the physical plant, and connects with PETRO to align the current operating parameters.

PETRO uses distributed recursive linear programming to guide users in choosing the most optimal sets of decisions, from feedstock selection, to process execution and to production portfolio creation. Data coming from PETRO are then fed into scheduling solutions such as Visual MESA^® Supply Chain Scheduling.

PETRO is Chevron’s proprietary petroleum supply chain planning software.
