Oil and Gas
The oil and gas industry involves a number of processes such as exploration, extraction, refining, transporting, etc, mostly of fuel oil and gasoline (petrol). Petroleum is further used as a raw material by various other industries including chemical, pharmaceuticals, fertilizers, pesticides, etc. But due to the volatile environment of oil fields, it is necessary that certain parameters such as temperature, pressure, flow, etc are consistently monitored for ensuring safety and optimization during operations. Sensors go a long way for incorporating such measurements with accuracy and reliability.
Petroleum exploration and research
Extracting oil from oil field requires a timely and effective extraction as only 15 % of the available oil actually makes it to the well bore during the extraction process. This is due to the porous and permeable nature of the reservoir rocks, in which the oil is found. To overcome this problem, several recovery techniques are employed for extending the life of an oil field and maximising the profit. The research for these techniques rely heavily on pressure transducers.
Structural health monitoring in marine oil and gas
The on-site equipment and infrastructure in a mining site need to be regularly monitored for health and compliance concerns. Although, due to the site being remotely located in a very less accessible location, the condition monitoring becomes very tough. To know the condition of an equipment, it’s good to know the vibration level of the equipment. Wireless accelerometers are ideal for use in this situation for dynamic measurement on embedded equipment.
Measurement of LNG tank movement caused by calamities and vibrations
LNG tanks store LNG (Liquified Natural Gas) compressed at medium pressure for ease of storage and transportation. Movements to these tanks can be due to earthquakes, floods, or vibration of subsea and underwater tanks and these tanks are susceptible to damage when subjected to such seismic excitations. The receives a big impact pressure at the wall and bottom plate due to the sudden change in the conduct of the interior fluid. To measure the movement of the tank, special LVDT sensors are considered suitable for use.
Detecting anomalies in pipelines
Pipelines are considered the most economical and safest mean of transporting crude oil. Several factors such as maintenance, sabotage, corrosion, and ageing pipes and fittings may often contribute to forming an unintended leak that may end up in financial losses, as well as damage to reputation and the environment. Hence, a well-versed approach for monitoring unmanned pump stations is designed to remotely monitor oil pump stations for leaks in an automated way.
