Maintaining the integrity of this infrastructure is critical to prevent leaks, spills, and disruptions to the supply chain. It's a complex and often overlooked part of the process, but absolutely essential.

Processing natural gas involves removing impurities such as water, carbon dioxide, and sulfur compounds to meet pipeline quality specifications. This often takes place at gas processing plants located near production sites. Crude oil may also undergo initial processing to remove water and sediment. These initial processing steps are crucial for ensuring that the oil and gas meet the required quality standards for transportation and refining. The processed oil and gas are then ready to be transported to refineries, storage facilities, or distribution centers.

Transportation is a critical aspect of the midstream sector, with pipelines being the most common and efficient method for moving large volumes of oil and gas over long distances. A vast network of pipelines crisscrosses the country, connecting production areas to demand centers. These pipelines are continuously monitored and maintained to ensure their integrity and prevent leaks. In addition to pipelines, other modes of transportation include tankers, barges, and trucks, which are used to move oil and gas to areas not accessible by pipelines. The choice of transportation method depends on factors such as distance, volume, and accessibility.
