The pressure window is the gap between pore pressure and fracture gradient. In depleted reservoirs, deepwater wells and certain geological settings, that gap narrows until conventional drilling cannot keep the well in it: raising mud weight causes losses, lowering it allows influx. Managed pressure drilling solves this by adding surface back-pressure as an adjustable component of bottomhole pressure.

The system is closed, which changes everything about detection. Returns go through a choke and a flow meter rather than to an open flowline, so small influxes and losses are detected far faster than by pit volume alone. That early detection is itself one of the main safety benefits, independent of the pressure control.

The complication is the boundary with conventional well control. An influx taken while drilling with managed pressure may be circulated out through the MPD system or may require conventional shut-in and kill, and the criteria for switching need to be defined, agreed and drilled before the well starts. Most of the procedural work in an MPD operation concerns that boundary.

By the end of this training, participants will be able to:

• Explain managed pressure drilling concepts and the pressure window problem.
• Compare MPD variants and select the appropriate method.
• Specify MPD equipment, including rotating control devices, chokes and back-pressure pumps.
• Describe control systems and automated pressure control.
• Apply hydraulic modelling to MPD operations.
• Execute constant bottomhole pressure drilling and connection procedures.
• Apply dual gradient and pressurised mud cap methods.
• Manage influxes and losses within an MPD system and define transition criteria to conventional well control.
• Select candidate wells and assess the value case for MPD.
• Apply regulatory requirements and define competence and crew structure.

The course is instructor-led. MPD concepts and hydraulics are developed with worked calculations, and equipment and control systems are covered with schematics and operating procedures. Participants work through MPD operating scenarios, including influx and loss events and the decision to transition to conventional well control. The course is aligned with recognised well control practice and does not award accredited certification.

Organisations sending participants to this training will:

• Drill wells that cannot be drilled conventionally.
• Reduce losses, kicks and non-productive time in narrow margin wells.
• Improve influx and loss detection speed.
• Select MPD candidates and justify the cost.
• Build the procedures and competence that MPD operations require.

Participants will:

• Understand managed pressure drilling and its variants.
• Be able to specify MPD equipment and control systems.
• Be able to apply MPD hydraulics and procedures.
• Understand influx management and the boundary with conventional well control.
• Be able to assess MPD candidates and value.

• Drilling engineers
• Drilling supervisors and company representatives
• Well engineers working narrow margin wells
• MPD service company personnel
• Drilling contractors' technical staff
• Technical authorities for drilling operations

Upon successful completion of this training course, delegates will be awarded an official Certificate of Completion issued by the Petroleum Engineers Association (PEA), an ISO 9001:2015 certified training organization. The certificate carries 10 Credits and formally records the total learning hours completed.

Each certificate is signed by the Course Facilitator and the CEO of the Petroleum Engineers Association, and serves as verifiable proof of professional training that delegates can present to employers and professional bodies worldwide.
