Event Details

Course overview

Pressure (HP) (>10,000 psi) and High Temperature (HT) (>300°F) conditions are becoming more High routine drilling targets worldwide in the pursuit of deep gas reserves. This course delivers a comprehensive review of HP HT well design, engineering and drilling requirements. The content emphasis in this course/workshop is placed on current regulatory and standard operating principles of HP HT – right from a well's concept phase, through pre-planning, rig and equipment selection, the basis of well design, detailed design, engineering, offset study, and final drilling of the critical HP HT transition and reservoir zones. The challenges of geological risks and uncertainty with drilling fluids, cement design, equipment assurance and drilling problem prevention, solving and decision making, all require special attention. The course draws on several HP HT case studies from different drilling environments in conjunction with instructor led facilitation, use of multi-media files and most importantly individual and group led engagement sessions.
Equip a multi-disciplinary team to manage and control the drilling hazards and risks that exist in HP HT wells. This course also delivers a participative, practical program where individual and teamwork skills are developed to meet the HP HT drilling challenges presented.

The course is desgined for

The course targets any member of a project team: geo-scientists, engineers, technical, non-technical personnel at all levels. It also includes everyone involved in the design, construction, engineering, implementation and the drilling of HP HT wells. This course embraces drilling engineers with or without experience.
Pre-requisites: Basic knowledge and understanding of HP HT well's, 2-3 years' involvement in drilling projects in an operating, support or services role preferred but not essential.

Course objectives

Create an environment for a multi-disciplinary team to practically challenge HP HT standards, instruction,
well integrity practices and develop new concepts to well safety and performance.
• Identify and eliminate the drilling hazards and risks
within HP HT wells to as low as practicable.
• How to translate and sustain HP HT drilling case-study
findings, success and failure learnings into future
drilling projects.
• Awareness of key issues that exist in HP HT design, engineering and drilling operations.
• Increased proficiency with ability to address the key hazard and risks impacting HP HT drilling project delivery.
• Specific knowledge to skilfully control HP HT drilling problems as they arise, yet realize the importance of having necessary contingent mitigation in place for unexpected situations.
• Appreciate technical challenges and difficulties that exist, with new awareness to risk reducing and adaptive technologies being used and applied for specific HP HT drilling applications.
