Efield and Subsea

We learn everyday about something because of different reasons and context. This is true in social and work life both. While I was applying for a job in Oil and Gas field I come across the terms 'efield' and 'subsea'  in the context of software and technology..

efield :
The oil industry is increasingly relying on digital technology and Internet or web-based concepts in every aspect, from back-office accounting and e-procurement to making decisions based on modeling software, to actually drilling, completing and monitoring wells.It’s called the e-field, the i-field, the smart field, and the digital oil field. And it is a very good thing.

The eField is an advanced ICT framework supporting all work processes and operation requirements an O&G organization have. Primary activities when developing an eField framework will be identifying the work processes and requirements both horizontally and vertically in the O&G field organization that are critical for the business strategy, economy and safety for humans and the environment.
The eField facilitate the O&G production organizations needs. Remote operation is anticipated to have a central role in future O&G production. CORD [2] is an initiative addressing the need for development of methods and evaluation of different concepts. The CORD program is currently working on identifying the work processes and requirements in an offshore platform control room. This is as a part of a larger program on how to safely move control functions, which today are controlled by the offshore control room, to a remote location. Important project participants are Statoil, BP, Shell, SINTEF and IFE.

Subsea :
Subsea is a general term frequently used to refer to equipment, technology, and methods employed in marine biology, undersea geology, offshore oil and gas developments, underwater mining, and offshore wind power industries.Oil and gas fields reside beneath many inland waters and offshore areas around the world, and in the oil and gas industry the term subsea relates to the exploration, drilling and development of oil and gas fields in underwater locations.Under water oil field facilities are generically referred to using a subsea prefix, such as subsea well, subsea field, subsea project, and subsea development.

Subsea engineering or seabed-to-surface engineering, is a specialty job that deals with underwater projects. A subsea engineer generally designs and installs underwater structures, including oil well rigging, wellheads, and pipelines. Typically, subsea engineers have working knowledge of underwater procedures, vehicles, and equipment.
