Abstract:

As one of the important economic indicators for the development of shale/tight reservoirs, the production performance and EUR calculation of shale/tight wells is an important subject in unconventional reservoir engineering. This has been challenging for the reservoir engineers from both China and other country for a dozen of years. Based on the understanding of the unique geological characteristics of shale/tight reservoirs, this paper describes in detail the production performance of those wells producing extremely tight reservoirs, from which the inapplicability of using traditional methods has been explained. Further, a new methodology and the workflow has been presented from SPEE recommendations, and one practical example has also been illustrated of implementing the workflow.

Key words: shale, tight formation, production behavior, production forecast, EUR estimation
