Digital solution — to enhance management innovation
Business function
LOBs operate independently, with shared business activities. The LOBs are optimized, without enterprise-class collaboration. Business 1 Business 2 Business 3
The enterprise improves the business structure, centralizes common business activities in the processing center, and
standardizes the process.
The information system is not applicable to the new business model.
Enterprise functions are modularized, creating a business function network based on task specialization.
Modules are standardized, improving and expanding enterprise capabilities.
Modules are seamlessly integrated and loosely coupled through the process.

A digital oilfield is a virtual display of the oilfield entity on the computer,
enabling data acquisition, querying, and interaction with the oilfield entity.
Features of the application system:
Unified architecture: performs planning and design in a unified manner, enabling integration.
Uniform platform: reduces the construction difficulty and improves the construction speed.
Integrated applications: integrates all oilfield applications and enhances the application results.
Independent property rights: reduces the upgrade and improvement costs, shortens the development period, and improves the adaptability.
After the construction of the digital oilfield is completed, oilfield
informatization progresses to the intelligent stage.

A digital oilfield is the presentation of an oilfield entity on the computer, where the computer functions like
human hands.
An intelligent oilfield is built on a digital oilfield to improve simulation and analysis, automatic processing, and
expert support, where the computer functions like human brain.
In simple terms, digitalization allows you to view things at will and intelligence allows you to do things at will.
