SPE-Number181480-MS Novel Method for Evaluating Shale Gas and Shale Tight Oil Reservoirs Using Well Log Data

摘要: This paper introduces a novel method for improved evaluation of shale gas reservoirs, shale tight oil reservoirs, and immature organic shale source rocks. The method provides exact and original algebraic equations for determining total porosities, producible fluid volumes, total hydrocarbon volumes, kerogen volumes, and immobile hydrocarbon volumes. The determination of accurate porosities and fluid volumes in organic shale reservoirs is critical for formation evaluation considering the low porosities (3 to 8 pu) typically found in shale reservoirs.
