An Oil and Gas Big Data Sharing Model Based on Blockchain Technology

Abstract

Abstract With the continuous in-depth application of new technologies such as big data and Internet of Things in the oil and gas field, the scale and value of oil and gas data continue to rise, laying the foundation for oil and gas big data sharing. Oil and gas big data sharing can effectively integrate different data sources and break the dilemma of “data islands” where data in the oil and gas field are separated from each other. However, there are problems in actual practice such as (1) difficulties in trust among different government departments, scientific research institutions and enterprises, (2) insufficient data privacy protection, and (3) weak data traceability. In response to the above problems, this article proposes a model of oil and gas big data sharing based on blockchain technology. We build a blockchain for oil and gas big data sharing alliances to secure oil and gas big data by utilizing the decentralization and non-tampering characteristics. We also provide supports for oil and gas big data sharing by controlling data access strictly based on the smart contracts. The evaluation and analysis results show that this model makes oil and gas big data more secure and authoritative compared with the traditional centralized sharing method.
