Abstract: The E&P Dream Cloud platform developed by PetroChina contains a unified Data Lake, a unified technology platform, and a general application environment. It supports the creation of a cloud-native exploration research environment which has been implemented and applied in oil and gas geophysical exploration companies in China. The key factors for improving efficiency and results quality in geophysical prospecting are to integrate seismic acquisition, processing, and interpretation, to integrate ‘front’ and ‘rear’ operations (on-site and at base), and to integrate companies running and administering projects with contractors working on their projects. Relying on the Data Lake resources of the individual oil and gas field companies within Dream Cloud and the customizable development capability of the E&P Dream Cloud platform, this paper studies and explores the characteristic mode of integration of seismic data processing and interpretation within the system, and constructs a work and research environment for the integration of front and rear operations, as well as the integration of project companies and contractors. This research advances the ongoing transformation from traditional seismic data processing and interpretation, builds project scenarios for seismic processing and interpretation integration, takes full advantage of the “super project organization” capability in the E&P Dream Cloud, and achieves integration between the project company and its contractors throughout the process of seismic processing and interpretation. It also achieves efficient collaboration and software resource sharing between front and rear, and provides effective support for improving the core competitiveness of enterprises.
