Date:  5-9th February 2023
Location: Dubai
   

 

Instructor:

Dr. Hussain Rabia, SPE Distinguished Lecturer


Course Duration:

One week -  5-9th February 2023 - Dubai


Who Should Attend:

Drilling managers and drilling supervisors and drilling engineers. All engineers, geologists and  geophysicists involved in HPHT well operations. Some  field experinece is  beneficial for this course.


Objectives: (This  course is also suitable for  the 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.
