Introduction to HPHT Well Design
Format and Duration:
2 days
4 sessions
This course provides a comprehensive overview of basic well design specific to high-pressure, high- temperature (HPHT) reservoirs. Participants will be introduced to key areas of focus essential for effective HPHT well design. It also discusses the impact of temperature and pressure on well barriers, highlighting the unique challenges that HPHT reservoirs present to well barrier elements. Additionally, participants will learn about operational practices that are crucial for designing and executing HPHT wells successfully.
Business Impact: By understanding the unique challenges of HPHT reservoirs, participants will be equipped to design safer, more reliable wells, reducing the risk of failure and costly interventions. Improved well barrier integrity and optimized operational practices will enhance well control, lower non- productive time, and improve the overall efficiency and safety of HPHT drilling programs.

Instructors
Robello Samuel
Background
With 41 years of experience, he currently serves as a Senior Technology Fellow in Halliburton’s Drilling Division, where he leads research and engineering in well engineering, cyber-physical systems, artificial intelligence, and sustainability. Since 1998, he has advanced drilling technology, leveraging a multi-disciplinary background that includes operations, consulting, software development, and education. Prior to Halliburton, he worked for nine years as a field and drilling engineer at Oil and Natural Gas Corporation, significantly contributing to domestic and international oil and gas drilling and completion operations.
He is recognized for his groundbreaking contributions to drilling technologies and engineering practices, having received multiple prestigious awards, including the Gulf Coast SPE Drilling Engineering Award, the SPE International Drilling Engineering Award, the SPE Distinguished Membership Award, and the SPE Honorary Award—one of the highest honors presented by the Society of Petroleum Engineers (SPE), limited to only 0.1% of the organization’s membership. An educator for over two decades, he is also an adjunct professor at the University of Houston and the University of Southern California, and has published more than 264 technical papers while holding 114 U.S. patents.
As a Commissioner for the Accreditation Board for Engineering and Technology (ABET) and a representative on the SPE Research and Development Advisory Board, his influence extends beyond academia. He has authored fifteen books on drilling engineering, blending extensive industry experience with academic rigor. His unique combination of practical field experience, research expertise, and educational leadership allows him to profoundly impact the industry, driving innovation and sustainable practices in drilling engineering.
