  • Managed pressure drilling technologies deployed for deepwater and HPHT well control in Indonesia

    Ardia Karnugroho, Fikri Irawan, Julius Sosa and Julmar Shaun S. Toralde

    Drilling difficult deepwater and high-pressure, high-temperature (HPHT) wells in Indonesia presents complex challenges that increase risk beyond what is typically experienced in most conventional wellbore construction operations. Extreme drilling environments present distinctive hazards, including riser gas (gas influxes in oil-based mud that later expand in the riser) and narrow mud weight windows (where small pressure changes during drilling could induce either a kick, or a loss), that hinder the ability to safely drill ahead.
