Combination of IT and automation & instrumentation technologies yields digital oil field technology, as an enhancement of the existing technologies in the oil & gas industry. This integrated operations technology makes the analysis faster and easier in supplement with software involved in efficient data management, issues more realistic image of the reservoir and the availability of resources,aids to optimize process required for production, and furnish much safer operations with the inclusion of remote surveillance and collaborated environments.. Automation & instrumentation is a segment of digital oil field market, which includes key networking processes and communication technologies such as SCADA, PLC, smart well, safety systems, and wireless systems.

Applications Of Digital Oilfield-
- Reservoir Optimization
- Production Optimization
- Drilling & Well Completion
Drilling & Well Completion Process-
The well design process begins with an understanding of the environment in which the well will
be drilled. Interpretations of local geologic structure, geo-pressure and formation strengths are
developed. These interpretations may be derived either from local drilling experience or from
seismic data. It should be noted that uncertainties will exist in the interpretation of the data and
ultimately in the description of the geologic environment. The quality of geologic predictions
(e.g., pore pressure, fracture gradient, bottom hole temperature and pressure, formation fluids,
H2S, CO2, chloride concentration, etc.) often relies on the amount of control within a given area.
As such, these predictions are usually expected to be more reliable for development wells than
for exploration wells. However, for drilling operations in established deepwater fields, the pore
pressure and fracture gradient often demonstrate variability due to production.
With a description of the geologic environment in place, constraints are then introduced by the
designer to address specific well requirements. These include the directional drilling objectives
and the required well depth. Production or evaluation requirements dictate the hole size desired
at total depth. Depending on the geographical location, some wells will require an additional
surface casing string for the isolation of shallow water or gas flows.
Market Trends & Forecast-
The global digital oil field market in terms of revenue was estimated to be worth $18.7 billion in 2011 which is expected to reach $27.9 billion by 2017, and $33.3 billion by 2022, growing at a CAGR of 4.8% from 2012 to 2022. Western Europe dominated the global digital oil field market, accounting for 26.9% in 2011. Middle East is expected to be the fastest growing market in the near future, reassured by high exploration activities and abundant resources.
