HPHT Operational Awareness And Drilling Challenges

Ref : OAG_HPHT_10
05 Days

This course covers all major aspects of HPHT well construction projects. It covers the theories, technicalities and practicalities of HPHT wells complete with impending risks and challenges. This course is also equipped with case studies on both successful HPHT well projects and the mistakes of past projects. Special emphasis is placed on Geopressure detection analysis. There are also practical exercises and assessments throughout this course with interactive discussion to meet the specific needs of all the participants.
This course aims to equip participants with the knowledge and understanding on ways to overcome the challenges and risks in HPHT wells while elevating the effectiveness of their HPHT wells practices, giving special emphasis on methods to detect and analysis Geopressures in HPHT wells.
This focus of this training is more than merely imparting technical knowledge; it works on improving communications and personal focus. At the end of this HPHT training, the attendees will have obtained a much improved understanding of the challenges which will be faced and the mitigations required to minimize the probability of failure. Team building, safety leadership and communication skills are key elements addressed in the course.
