Discipline: Operation Geologist
Level: Foundations
Duration: 5 days
Instructor(s): Gonzalo Ruiz, Jesus Sotomayor


At the end of this integrated course, participants will be able to contribute effectively to the preparation of planned wells and their concurrent operations during the exploration, appraisal, and development phases. All should be able to understand and prepare daily drilling reports with a full appreciation of the various subjects. Cuttings, core, logs, and well tests should be analysed, cross-correlated, and compiled to mesh with prognoses and existing data to effectively manage the impact on the field development plan. Correct procedures in tendering and contracting should be followed to minimize the duration of the operations and to maximize the quality of the operations services provided. Understanding of all operations should greatly improve the effectiveness of the well site geological operations.


All geoscientist, petroleum engineers, well engineers, and technical personnel, who while their career will attend or supervise subsurface and wellsite operations.
