ABSTRACT
Oil production is a fiercely competitive business. Because oil deposits are finite resources, the leased area becomes quickly and densely populated with drilling platforms and production, including pumping and transporting operations. To maximize productivity of each oil platform, all aspects of production involving monitoring and control of repetitive function need to automate.
Operating an oil and gas extraction facility offshore presents a list of difficulties. The marine environment is highly corrosive, meaning any platform erected will require intensive maintenance and upkeep platform are typically located in 150 to 350 feet of water, up to 10 miles offshore. The platforms usually must drill several thousand feet below the ocean floor to reach oil and gas deposits. When high seas and heavy winds or hurricanes approach a platform, crew must evacuate to prevent injury or loss of life. To future this end, labor-intensive, repetitive tasks such as opening and closing valves, monitoring levels etc must be automated.
The obvious benefits are to reduce cost and ensure timely completion of tasks. The programmable logic controller (PLC) serves extensively to continuously monitor and handle routine operations. The PLC allows valve status; fluid levels, and also allows a platform to shutdown during emergency and thus avoids damage to the equipments. Thus PLC's are widely used in oilrigs.

Information in this page is very informative and useful.One of the major profitable industry is Oil and Gas sector.Offshore sector using digital technology to get real time data and also improving the life of well and safety.Oil business is now less about 'exploration' and more about efficiencies.Let's see how this digital oil field going to help the industry's labour shortage with right skills in place.
Very nice blog more information our sites
