Cloud computing is a method of delivering IT services where resources and data are retrieved from the Internet using web-based applications and tools, and not through a direct connection to a server. Cloud computing makes it possible to store files and data remotely from the workplace and reduces the need for a local storage device or computer hard drive. However, to access data in the cloud, a user must have access to the web. Cloud-computing technology enables employees in the oil and gas sector to work remotely and to analyze extensive amounts of data at a lower cost. Delfi is an example of a cutting-edge software system that utilizes cloud computing to coordinate oil well data. By analyzing how wells are designed, drilled, and configured for production, the software program can maximize output for an oilfield and dramatically cut down costs.
