This book with entitled PETROLEUM APPRAISAL AND DEVELOPMENT: GEOLOGICAL REVIEW & RESERVOIR SIMULATION ("W" Field, Bintuni Basin) is a feasibility evaluation in the form of Review of Geology, Reservoir simulation and Economic evaluation in the development of an oil and gas field. In this book the authors provide evaluation examples on the "W" Field, Bintuni Basin.The purpose of writing this book is to: (1) Review the geological model and reservoir model of the "W" Field, Basin Bintuni, (2) Conduct reservoir simulation to estimate production and injection performance in "W" Field - Bintuni Basin, if waterflood is carried out by using several development scenarios. This Evaluation Book can be used to choose the best method to increase oil acquisition in the field which has the same geological and reservoir characteristics of the field, while the economic parameters can be changed according to technical and non -technical.
