Agenda

Over recent years, the MPD sector has been through a period of continuous development with respect to the Rotating Control Device (RCD), Continuous Circulation Systems (CCS), Automated Back Pressure Management (ABPM), and Hydraulics Modelling Software (HMS). 

This session will present some of the latest improvements in these technologies, including case histories of successful implementation. It will also highlight new innovations in RCD technology that have challenged the traditional designs, resulting in step-changes in safety and operational performance. The latest developments in CCS and HMS will also be showcased and discussed.   

Key areas that will be discussed during this session:

• Improvement in seal technology and bearing design - challenging the industry “normal” to deliver breakthrough performance 
• Non rotating RCD options and simplification of RCD components
• Seal performance monitoring - ensuring barrier integrity
• RCD systems for dry (above tension ring) and wet (below tension ring) risers
• Latest developments and experiences in CCS
• Fit-for-purpose HMS 

Presentation Topics:

• Drilling Narrow Pressure Margins with 2-Phase Managed Pressure Drilling and Continuous Circulation, Rachel Johnson, Halliburton 
• CCS - Best Practices for Using Continuous Circulation in conjunction with Other Rig Data and Systems to Drill ERD Wells by Managing ECD, Bottom Hole Pressure and Hole Cleaning, Scott Petrie, Adrilltech 
• Best Seal Performance Monitoring with Non-rotating RCD Systems, Christine Madsen, Wellis MPCD 
• Breaking Barriers – Moving the Goalposts for RCD Reliability, George Michaund, Beyond Energy 
• Integrated Hydraulics Modeling and Control System for Managed Pressure Drilling, Sayamik Ameen, Weatherford

The technological advancements in MPD enable us to drill and explore more complex subsurface objectives; however, the inevitable shift in investing in more MPD capable rigs is a challenge to the industry. This bears the question: What does a MPD “capable” rig mean to operators as well as the drilling contractors?

This session will cover fit-for-purpose MPD capable rigs, as well as issues faced by both operators and drilling contractors in its implementation. 

Presentation Topics:

• MPD Capable: An International Drilling Contractors Perspective, Nick Ward, Stena Drilling 
• Noble Integrated MPD Model, Sebastian Van Diemen, Noble Corporation

Besides the requirements for various types of MPD, such as constant bottom hole pressure or mud cap operations, the objectives of this session will be to present and discuss the challenges associated with operations and development of future MPD systems on floating rigs. MPD from floating rigs on subsea wells introduces several additional challenges when compared to MPD on surface wellheads. The location of the rotating control device is only one of these challenges, as RCDs can be installed above or below the riser tensioner system. This session will hold discussions on:

• Overview of global deepwater MPD operations and rigs that have been used
• Various deepwater technical challenges
• Planning and designing of the MPD operations on floating rigs
• Mobilising, installing and interfacing an MPD system on a floating rig
• Drilling contractor MPD operations on floating rigs
• Operator requirements for MPD operations on floating rigs
• Drilling marine riser challenges on floating rig MPD systems
• The future of floating rig MPD systems

Presentation Topics:

• Well Planning and Designing Considerations for Deepwater MPD Operations, Henry Pinkstone, Wellspec
• Deployment of an MPD System Optimised for Drillships and Semi-Submersibles, Brian Piccolo, AF Global & Sebastian Van Diemen, Noble Corporation
• Rig Integration of Hands Free MPD, Scott Bremner, Weatherford
• Agile MPD Integration, Konstantin Puskarskij, Maersk Drilling & Hon Lom Hooi, Maersk Drilling
• Successful Delivery of an Integrated Deepwater MPD Service: A Case History, Nick Ward, Stena Drilling

MPD systems enhance a rig’s primary barrier envelope and consequently improve drilling safety. Influx detection and control algorithms have recently been augmented with the primary barrier influx circulation methodology through the use of tools like the Influx Management Envelope (IME). The IME is a detailed graphical representation of post influx suppression, influx volume and influx intensity; an approach which is being widely adopted by the drilling industry.

This session will focus on how IME and related approaches are being used on current MPD projects, and the session will discuss:

• An overview of the IME approach
• The thin line between yellow and red: Understanding personnel interfaces when an influx is determined too large to be handled by the primary barrier equipment
• Influx management training
• Case histories from projects across the globe on the use of the IME approach
• Developments in IME technology
• An update on IADC and API adoption of the methodology

Panel Speakers:

• Factors that Affects MPD Influx Control & Circulation: IME Execution Consideration, Harshad Patil, Weatherford 
• The Influx Management Envelope: Now and the Future, Martin Culen, Kelda Drilling Solutions 
• Understanding Downhole Dynamics When Open Hole Fracture Pressure is Exceeded during Influx Circulation, Peter Slagel, PETRONAS 

This session will focus on the latest developments, applications and case studies of drilling technologies in the 2-phase MPD market in Asia Pacific. These are:

Under Balanced Drilling (UBD)

• New advances/developments in (2-phase) UBD procedures
• Technical and equipment design and implementation
• Cost-effectiveness of UBD application in the bearish oil market
• Recent UBD operations/case studies for both onshore and offshore

Managed Pressure Drilling (MPD)

• Automated bottom hole pressure control and hydraulic modelling in 2-phase MPD drilling
• Low head pressure drilling developments
• Recent 2-phase MPD operations/case studies, for both onshore and offshore

Presentation Topics:

• Automated Pressure Control for UBD Operations: Case Study and Field Validation, Martin Culen, Kelda Drilling Solutions 
• First Implementation of Under Balanced Drilling in India, David Yu, Halliburton 

This session will focus on how the MPD/Pressurised Mud Cap Drilling (PMCD) technology has expanded and advanced into various applications beyond the applications of managing bottom hole pressure in the old days. The experiences and lessons learnt from previous MPD/PMCD methods, gained over the past few decades, have now increased the level of confidence in our industry.

MPD has now evolved into a new era that was previously not possible in the past, thanks to new technologies. Some of the most recent technology advancements in MPD techniques for managing challenging bottom hole pressures include static underbalanced mud weight applications, circulating out-kick with the MPD system, managed pressure cementing, dual gradient drilling, MPD for wellbore instability/stuck pipe prevention scenarios and drilling severely depleted reservoirs.

PMCD is another variation of MPD which involves drilling with no returns to surface using a sacrificial drilling fluid (normally seawater) and a light annular mud with surface pressure above, for drilling formations suffering total losses, and therefore capable of accepting fluids and cuttings. Various applications of PMCD and its advancement in this region, especially in carbonate and basement drilling, will be discussed in this session.
