Dr. Hussain Rabia, SPE Distinguished Lecturer

Course Duration:

One week  : Dubai

5-9th February 2023

Who Should Attend:

 Drilling managers,drilling supervisors and drilling engineers. All engineers, geologists & geophysicists who are involved in HPHT well operations.Some wellsite or operations experience and a basic knowledge of geology are beneficial for this course.

Objectives: (This  course is also suitable for  ADVANCED WELL CONTROL)

To explore the challenges of drilling and evaluating HPHT wells. Engineers will learn about well planning processes, the drilling and geological challenges presented by HPHT wells and explore pore pressure detection processes, rock fracture pressure and ECD requirements and well control procedures. Advanced casing design methods will be presented. Drilling practices and well control equipment and well control methods will be explained. Engineers will be asked to carry out an HPHT well design using real data.
