Abstract

Abstract: Geology-engineering integration is widely recognized as an effective process in the exploration and development of unconventional oil and gas reservoirs. It involves massive data of various disciplines including geology, reservoir, geophysical exploration, drilling, mud logging, well logging, well test, production test, production and downhole operations. Since professional personnel/organizations have different understandings and requirements for specific data, the data systems can hardly be connected and interacted among disciplines, which may form "data islands". Based on the system platforms of data lake and knowledge database for the life cycle of reservoirs, the core data of geology and engineering are selected and the core "gold data" of exploration and development are identified to realize convenient and efficient communication and interactive optimization of professional data. In this way, the geology-engineering data can be integrated to greatly improve the efficiency and accuracy of data utilization. For purpose of effective geology-engineering integration, an integrated project organization and management framework is proposed, and the decision-making, coordination and information feedback mechanisms are established. Moreover, more sophisticated technology management is implemented, and key links in production arrangement and implementation are optimized. Thus, the best economic benefits can be expected.

Key words: geology-engineering integration, data lake, data island, gold data of reservoir, data optimization, efficient management
