 Comparative advantages

Focuses on production well troubleshooting and fluid production calculation, but does not provide business management or other complex analytical functions.

The product is deployed in a centralized way, and all data need to be aggregated to the software deployment terminal for calculation and analysis.

Expensive in both the software and hardware sectors due to product development and production costs.

Usually tied to the sale of electric diving equipment, the product does not provide customized services product software model for a set of common models

O&M services are not usually provided as they are tied to the sale of other equipment and are heavily influenced by contracts for the purchase of other equipment.

The cost of operation and maintenance is high. The basic functions of production diagnosis and yield calculation are upgraded to the management of business processes and reservoir and knowledge management, realizing the whole life cycle management and auxiliary decision-making for production increase.

Flexible product architecture, on the edge side of the data can be analyzed in situ, to improve the corresponding speed, saving the deployment of the cost of the link cloud program problems do not affect the edge side of the diagnosis and computing

The price advantage is obvious, the deployment cost of the whole set of intelligent hardware and software accounts for a very small proportion of the overall production cost.
