Wellsite geology & Operations

John Keasberry 
5 days

Business context

A large amount of geological data is acquired (at substantial cost) during a drilling operation. Ensuring optimal quality of this information and effective reporting plays a key role during well design, drilling operations as well as at the later use of the data in field studies.

A key requirement for success is close co-operation between geological, drilling and well engineering departments.

Who should attend

Well-site geologists, drilling and operations engineers and other staff involved in the acquisition and use of well-site (geological) data.

Learning, methods and tools

At the end of the course, participant will have grasped the basic principles of well-site data acquisition quality control. They will learn the techniques used by well-site geologists in formation evaluation through lectures, integrated with practical exercises. Participants will be using the microscope for cuttings analysis and UV light boxes for oil show examination.

Participants will acquire understanding of drilling problems caused by subsurface conditions, and of application of well-site data in exploration and development.
