Jakarta – To support the acceleration of employee competence development within the Company, PT Pertamina Hulu Indonesia (PHI) held the MAST3R Program, short for Mentoring and Area Skill Transfer for Effective Acceleration. The MAST3R Program covered both technical aspects and soft skills through direct involvement in strategic projects, mentoring from senior professionals, and opportunities to build cross-functional networks.

The program, with the theme “Fostering Talents, Building the Future”, had run since June 2024 and officially concluded on August 15, 2025.
