Abstract
Electric Power Development Company Ltd. (EPDC) has been conducting an exploration and reservoir evaluation program in the Oguni field, central south-western Japan since 1983. EPDC has carried out various geophysical surveys, and has drilled 23 wells. As a result of these surveys, it has become clear that this field is characterized by the following three factors; high permeability in a wide area, moderate temperatures of 200 to 240 and carbonate scale deposition in some production wells. This paper presents the characteristic features of the reservoir, and development plan for the reservoir.
