Multivariate statistical process control (MSPC) methods can be used to monitor offshore equipment onshore. Models of a compressor’s operation can be created using the MSPC techniques of Partial
Least Squares (PLS) and Principal Component Analysis (PCA) to prevent downtime from occurring or, at the very least, keep it as minimal as possible. The models use historical data and can help to
predict compressor problems before they become critical and allow essential maintenance to take place before downtime becomes unavoidable. The models can also be used to detect when a component in the compressor process has changed.

Upstream Technology is the first publication to explore the impact of information technology (IT) on the upstream sector of the energy industry. Readers will learn about the impact of mergers on major oil companies’ IT departments, gain insight into how e-business technology is expanding for E&P applications, how technologies are improving operations, financial performance, and ultimately shareholder value, and much more. As the energy industry and the Internet become more intertwined, Upstream Technology will continue to provide objective, comprehensive information about the upstream sector’s IT developments as a whole.
