This course describes the modern role of the operations geologists. It will include duties and responsibilities with respect to data management, well planning, subsurface hazard identification and mitigation, contractor selection and management, HSE, data acquisition planning. The course covers the well execution phase, monitoring of coring, wireline logging, geosteering, and pore pressure evaluation. Post well duties including end of well reporting, data distribution and archiving. The candidates will learn both basic and more advanced skill sets that the operations geologist needs in the oil industry today. They will be more able to conduct the geological planning for a well including risk analysis, formation pressure forecasting, and data acquisition programs. The candidates will also be able to monitor the execution phase of the well, make informed decisions, manage data, and advise on coring and wireline logging activities. They will also be able to manage end of well activities including reporting, lesson learned meetings, and final data distribution.

By the end of this course delegates will be able to:

• Understand basic principles of wellsite data acquisition and quality control
• Apply the techniques used by well geologists in formation evaluation through lectures integrated with practical exercises
• Perform useful exercises of cutting analysis and oil show examination
• Acquire the understanding of drilling problems caused by subsurface conditions, and of applications of wellsite data in exploration and development
• Conduct the geological planning for a well including risk analysis, formation pressure forecasting and data acquisitions programs
• Manage contractor activities and maintain quality control on data acquisition and operations
• Monitor execution of the phase of a well, make informed decisions, and manage data, and advise on coring and wireline logging activities
• Organize end of well activities including reporting, lessons learned meetings and final data distribution
