A profitable development of an oil or gas field starts with a good understanding of the subsurface. As part of a PE team the development geologist interprets subsurface data and provides geological models that form the basis for development planning.
During this course the “development life cycle” starting with the gathering of geological data, the interpretation thereof, the preparation of geological models and the quantification of subsurface uncertainty are discussed. The development geologist is equipped with the skills to construct these models. Attention is given to the impact on field operations and on field management during its entire lifecycle.
In addition to the ones quoted in the course schedule (relating to the Robin Field) dedicated exercises are included throughout the course to ensure participants understand the concepts discussed.
Options: this course can be tailored to pure clastic or pure carbonate reservoirs on Client’s request.
