Customised HPHT Training: Theory Brought to Life

Aberdeen Drilling International recently designed and delivered a 3-day well-specific HPHT Drilling course in collaboration with a major international operator at our Malaysian training centre.

Our in-house technical team worked closely with the Drilling Superintendent who shared their well data and made invaluable contributions to the course development, which meant we could successfully deliver an engaging and well-specific course split between classroom theory and simulator-based practice. We were grateful to receive fantastic feedback and were provided with the following end-of-course report:

“The HPHT Drilling course [included] actual well scenarios (in this case at the verge of HPHT) being drilled in offshore Malaysia. The HP section of the well is to be drilled with MPD assistance due to narrow PP/FG envelope. The designed course was very balanced with theory sections including the engineering aspects of the HPHT well that needed to be considered in operations. The simulator exercises that were conducted on conventional and MPD assisted drilling were challenging with the Team making the decision in every step to deliver the well with discussions at various levels. 

In summary the course has provided our engineers with a very good well rounded experience of real life well situation on:

1) Effect of pressure and temperature on density
2) Effect of ECD in tight window and the ESD with thermal influence 
3) Gas behavior in WBM and SBM
4) HPHT fingerprinting requirement
5) Well losses/kick scenarios 
6) Discussion on well kill methods including bull heading option
7) MPD/surface pressure limitation – pumps on and off back pressure calculations
8) Mud weight/back pressure manipulation
9) Kick tolerance and integrity of the hole section
10) Extension into safely cementing the well with the available fracture margin 
11) Discussion of a case study of real well scenario in the industry 

The trainers were well versed with HPHT knowledge and experience, with open communications maintained throughout the 3-day course. The course was conducted very interactively for better understanding of the HPHT subject and the Team gained a lot of knowledge throughout the classroom and simulator exercises.”
