Session Managers: Haas Malik; Anil George Lasrado, Enhanced Drilling; Prem Ananthan Sridharan, INPEX Malaysia

This session aims to showcase and discuss enhanced optimisation processes during the design and well construction phases when utilising Managed Pressure Drilling (MPD), Underbalanced Drilling (UBD), or Dual Gradient Drilling (DGD) applications. It will feature case studies addressing key challenges in MPD, UBD, and DGD well design, such as navigating narrow pore and fracture pressure windows, high-pressure high-temperature (HPHT) conditions, stuck pipe incidents, and gas or water influxes, among others.

An optimised well design relies on an adaptive approach—combining scenario planning, regional expertise, the effective use of accurate data, and a collaborative multi-disciplinary team effort. These elements are critical to ensuring the well reaches its target safely and efficiently. This session will serve as a key enabler for unlocking innovative strategies and principles when working with MPD, UBD, and DGD technologies.
