Fraccability of the Miocene Onnagawa Formation and its relationship with microfacies analysis

Year: 2021

Type: article

Abstract: The Onnagawa shale is a middle Miocene deposit that extends along the Akita coastal area. This formation contains organic carbon enriched siliceous mudstones deposited in the basins during the early stages of the Japanese sea opening. Some researchers in petroleum geochemistry have demonstrated that these organically enriched rocks possess attributes common to oil source rocks. JOGMEC has previously perfomed shale oil reservoir characterization of the Onnagawa shale, pilot hydraulic fracturing tests, and coring through the Onngawa shales sequence. The main goal of this paper is to use methods to estimate rock properties characterized by porosity and permeability to develop an understanding of fraccability based on lithofacies and mineral composition and their distribution in the Onnagawa Formation.
