OPTIMIZING VALUE IN MANUFACTURING
Integration also allows us to capture significant value in our manufacturing operations. Our refineries and chemical plants are able
to process a wide range of feedstocks, which may include crude oils, natural gas liquids, and other streams. These feedstocks
are used in plant operations to produce higher-value products. Integrated teams develop strategies that bring together operational,
technical, marketing, and logistical expertise to identify the optimum product mix for each market.
Our Upstream Gas and Power Marketing organization supports these efforts, particularly in the area of natural gas liquids supply.
For example, in the United Kingdom, we are able to maximize the output of our North Sea natural gas liquids by providing
feedstocks to our onshore Fife ethylene plant in Scotland. We are expanding similar activities with our facilities in the United
States to take advantage of an increase in liquids-rich unconventional production, an effort further enhanced by the acquisition
of XTO Energy.
We also utilize computer models in our manufacturing facilities to optimize operations on an integrated basis to select the most
economically attractive crude oils and other feedstocks. We are able to maximize these benefits because 75 percent of our refining
capacity is integrated with our chemical or lubes operations, and more than 90 percent of the feedstocks for our chemical
operations comes from either our upstream production or our refineries. As an example of this integration, ExxonMobil refineries
provide feedstocks that our Chemical business uses in steam crackers and aromatics complexes. While most of the output
from the steam crackers results in chemical products, by-products are produced that our Downstream business can utilize
to capture additional value. These various outlets provide alternatives that enable us to obtain the highest value from each
molecule. This close interconnection is one of the central reasons we have 12 fully integrated refining and chemical complexes
across North America, Europe, and Asia Pacific.
UP CLOSE:
ESCAID FLUIDS AND THE UPSTREAM
During the drilling process, it is essential to remove material from the well that has
been cut by the drill bit. Drilling mud does this while also cooling and lubricating
the drill bit and preventing underground oil, gas, and water from coming to the
surface. The quality of the chemicals used to make drilling mud is of the utmost
importance. Working with the Upstream, our Chemical business developed
Escaid fluids to improve performance in extended-reach drilling while minimizing
environmental impact and enhancing worker safety. This is a powerful example
of the value added by our integrated business model.
