“Smart Oil and Gas Production Technologies”

(“Russian Smart Oil Technology”)

 

Relevance. The hydrocarbon (HC) field development technologies applied in the Russian Federation provide for the oil recovery rate (ORR) of 30% with an overage water content over 84%. The worldwide average ORR reaches 40% with average water content of approximately 75%. In the context of decreasing prices for oil, the single reasonable approach to decrease the cost of oil production consists in the shift of development to a qualitatively new – smart HC production level.

Objective. ORR enhancement within the operating fields by 10-15% and within newly introduced ones – by 15-20% from the planned design solutions.

 Method to Achieve the Objective. Permanent control over the field exploration processes can be provided based on application of modern total systems of geophysical field registration and supercomputing technologies.

 Scope of the Project:

 

1. Process instrumentation of the new generation of geophysical field registration.
2. Application software for collection and supercomputing processing of the registered data.
3. Geological and geophysical databases and knowledge bases for the development objects.
4. Smart 4D technologies of continuous information support of the field development.
5. High-precision technologies influencing the field development process for efficient reserve recovery.
