This document discusses the application of robotics in oil and gas refineries. It begins by introducing the challenges of obtaining oil and gas from more difficult environments and the need for advanced technologies like robotics to improve safety and reduce costs. It then reviews the upstream, midstream, and downstream processes in the oil and gas industry to understand where robotics could be applied. Some key challenges of working in oil and gas refineries like hazardous atmospheres and extreme weather are described. The document also provides an overview of the components of industrial robots and examples of how companies like ABB are using robots in oil and gas applications like monitoring and maintenance.
