8:05 am  MPD – Growing the Technology: Chris Scarborough, Senior Wells Engineer – Well Control & MPD, BP
The presentation will raise questions into why the industry would not adopt a drilling technology that enables a greater level of control during the drilling operations and offers potential road blocks, as experienced by the presenter, to expanding the use of Managed Pressure Drilling.

8:25 am  Fluids for UBO & MPD

Three-Fluid System Allows Successful Completion of a Slim-Hole, +22000’ Well with a 0.5ppg Narrow Window: Philip Gunn, MPD Engineer, Leiro Medina, Beyond Energy, Gord Plouffe, Gabriel Soo, Jupiter Resources-Ramdar (SPE 200508)
Overview of Alberta’s deep basin challenges and narrow window drilling problems. Progress to increased MD:TVD ratios’ challenge and use of MPD to mitigate problems. Run through rigours of two fluid system and impact on EMW before running through use of diversion sub to position 3 fluid system with a stripping plan for the completion’s liner run with MPD.

Fluid Eliminates Compression Equipment in Underbalanced Drilling: Kevin Smith, President, Charles Bellinger, Natalia Collins, Highland Fluid Technology
A new MPF (managed pressure fluid) has been developed which eliminates the need for expensive compression, membrane nitrogen and highpressure 3-phase separation equipment. MPF is a simple, lightweight, incompressible drilling fluid and behaves like a conventional drilling mud. The presentation describes the new MPF properties and case study results. Ease of operation, elimination of expensive equipment, and reduced HSE risk, show a step change improvement in fluid technology, efficiency and cost reductions.

9:05 am  Case Histories/Lessons Learned

Offshore Drilling Contractors Journey from MPD Curious to MPD Leader in 4 Years: Nick Ward, Assistant Rig Manager, John Smith, Stuart Wyse, Sean Gray, Stena Drilling
A detailed examination of the journey undertaken by an International, Offshore Drilling Contractor from zero MPD capability, to providing a World Class, ‘Owned and Operated’ MPD Service to multiple International Operators in 3 years. Looking in detail at the delivery of the worlds first DNV DRILL (MPD) systems; the development of bespoke MPD procedures; the training of rig crews; and ultimately the successful delivery of safe and efficient MPD operations across three drilling units and seven deepwater wells.

Floating Mud Cap Drilling with Sandwich System Application in Indonesia Development Well: Ahmad Burhan Noviaris, Drilling and Workover Plan Engineer, Mustafa Syarief, Warnandes Ambar M, Reza Yudha P, PT Pertamina EP (SPE 200505)
Pertamina EP with North Kedung Tuban structure is to produce gas from “Kujung” carbonate formation. The characteristic are vugular rock which caused total loss circulation, contain high concentration H2S and 20% CO2. To encounter this, Floating Mud Cap Drilling technique with sandwich system was applied. The well completed with no gas kick and completion string placed as purposed.

Managed Pressure Drilling and Underbalanced Drilling Hybrid Solution: Delivering a Step Change in Performance in a Challenging Exploratory Biogenic Gas Well in the United Arab Emirates: Mujahed Saleh, Technical Sales Manager, Ayoub Hadj-Moussa, Weatherford, Muna Al Marzoqui, Ahmed Al Hanaee, Mohamed Samer Amin, ADNOC (SPE 200516)
Underbalanced Drilling (UBD) and Managed Pressure Drilling (MPD) played a key role in the delivery of a challenging exploratory well in an unconventional biogenic gas field in the United Arab Emirates. Successfully mitigating drilling hazards such as well control, drilling fluid losses, slow ROP and wellbore instability due to the presence of salt.

10:05-10:15  Break

10:15 am Significant Surge and Swab Pressure Variations Offshore Brazil induced by Rig Heave during Drill Pipe Connections: John-Morten Godhavn, Advisor, Banzi Olorunju, Equinor, Dmitri Gorski, Martin Kvernland, Mateus Sant` Ana, Heavelock Solutions, Ole Morten Aamo, Sigbjørn Sangesland, NTNU (SPE 200518)
This presentation describes simulated and measured downhole pressure variations during drill pipe connections when drilling a deep water well offshore Brazil. The rig heave caused by sea waves induced significant pressure variations downhole each time the drill string was suspended in slips to make connections. Downhole pressure variations induced by rig heave should be considered both during well operations and planning even in regions with less harsh weather conditions than in the North Sea, since there is a possibility that they can result in a loss or an influx.

11:05 am Well Control Considerations & Well Design

Managed Pressure Drilling Influx Management: A Comprehensive Analysis of IME, MPD Operations Matrix, Dynamic Kick Tolerance Concepts, and Parameter Sensitivity: Romar Alexandra Gonzalez Luis, Technology Development Engineer, Jorge Bedoya, Serkan Cenberlitas, William Bacon, Oscar Gabaldon, Patrick Bland, Blade Energy Partners (SPE 200514)
The presentation will cover three main aspects: MPD kick tolerance, including concepts and its variables of interest; IME generation and parameter sensitivity analysis; generation of an MPD operational matrix. Also, the advantages and disadvantages of various approaches to determining the limits of dynamic influx circulation will be presented.

The Influx Management Envelope; Sensitivity of Model Choice: Christian Berg, Research Engineer, Geir Arne Evjen, Martin Culen, Kelda Drilling Controls, Trygve Rinde, Ranold, William Bacon, Blade Energy Partners (SPE 200510)
There have been numerous developments of the IME in recent years, and it is gaining market over the well control matrix. Calculation of the IME can be done in multiple ways; simple ideal gas calculations typically give smaller acceptable kick sizes compared to high fidelity simulations. Some of this can be attributed to the use of real gas models, and some to more realistic distribution of gas in the wellbore compared to a single bubble. Results from computing the IME using a market leading drilling simulator as well as a market leading multiphase simulator are compared to the ideal gas IME by Culen et al. (2014) and the real gas IME by Berg et al. (2019). Discrepancies in the underlying models are discussed, and the differences in the resulting IME are elaborated.

An Integrated Approach for MPD Business Case Includes Well Design Optimization with MPD: Oscar Gabaldon, Operations Manager, Romar Alexandra Gonzalez Luis, Patrick Brand, Sherif Saber, Anton Kozlov, William Bacon, Blade Energy Partners (SPE 200509)
In HPHT reservoirs and exploratory wells, especially in deep water, high uncertainty can increase costs due to non-productive time (NPT) and high operational cost. For challenging wells with narrow windows, Managed Pressure Drilling (MPD) techniques offer cost-effective tools to increase the odds for achieving cost and well objective assurance while improving operational efficiency by reducing the degree of uncertainty and NPT. MPD can also be utilized for risk mitigation and enhancing safety. However, MPD has been mostly absent as a driver for well design process, which has resulted in missing an enormous potential to optimize the well design. The main drivers in casing point selection are the pore pressure and fracture gradients, which may have a high degree of uncertainty. Current well design process hinges on the ability to manage these uncertainties by company or regulatory requirements, such as kick tolerance. The degree of uncertainty on the pore pressure and fracture gradients is perhaps the most critical aspect in both well design and drilling operations. Through dynamically testing the formation pressure and fracture gradients, MPD operations enable real-time evaluation of the existing drilling window, allowing to reduce the uncertainty. Furthermore, the ability to detect and react dynamically to accidental conditions reduces the probability and intensity of the loads driving the well design. This provides a tremendous opportunity to optimize the selection of casing shoe depths. This work addresses drivers, enablers, and considerations related to optimizing a well design by taking advantage of dynamic processes facilitated with MPD. Also, guidance criteria to enable well designers to safely and efficiently optimize well design by taking advantage of MPD are provided. Finally, this presentation provides case studies of the technical evaluation and economic justification for implementing MPD. The cost savings from the impact on the well design are also discussed. New guiding criteria aim to constitute a systematic and integrated approach to ensure well integrity and optimize well design while also considering the operational implications and integral cost benefits.

11:35 am  Panel Session – HSE/Regulatory

8:10 am  Deepwater Applications

Using MPD to Optimize Well Design and Well Delivery Process for a Deepwater Exploration Well: Sharief Moghazy, Wells Engineer, Roger Van Noort, Wilmer Gaviria, Shell International E&P, Anton Kozlov, Clayton Hester, Inam Haq, Thiago Silva, Blade Energy Partners (SPE 200504)
The presentation will be a summary of the findings in the paper walking through the process of designing and drilling the well using MPD to optimize all aspects of the well delivery process.

Operator’s First Managed Pressure Drilling Well in Ultra-deep Waters of Mexico, a Challenging and Crucial Cementing Operation Successfully Conducted using Managed Pressure Cementing through an Automated Pressure Control System: Raul Bermudez, Fluids and Cement Engineer, Cyril Szakolczai, Juan-Jose Ferro, Christophe Birades, Total E&P, Julian Hernandez, Ryan Brinkley, Maurizio Arnone, Leonel Carreño, Weatherford, Landon Hollman, Ivan Torres, Halliburton (SPE 200503)
This well case study is an ultra-deep water exploration well drilled in the Gulf of Mexico in the Mexico side. From the onset of planning the base case was to integrate a Managed Pressure (MP) system into the drilling program to assist with pore pressure uncertainty, pressure ramp increase, and narrow PP/FG window operations including; drilling, tripping, running casing and cementing.

8:50 am  Panel Session – Fluids/Riser Gas
Moderator: Calvin Holt, CEO, DrillDocs Company
Gas in the riser of a deepwater drilling operation has historically been a serious hazard. With an increasing number of rigs being equipped for MPD operations or at least with a riser gas handler, the situation is changing. In this session, how gas actually behaves in a conventional open riser will be discussed. That will be contrasted with what can be done in a closed system and how deepwater well control may be improved.

11:30 am  Case Histories/Lessons Learned II

Real-time Downhole Pressure Measurements for Managed Pressure Cementing Operations: Andrew Hawthorn, Global Solutions Manager, Duncan Groves, Baker Hughes, Tom Brian, Total E&P (SPE 200519)
Managed pressure cementing is challenging due to the lower annular clearances and higher densities of fluid utilized. Until now there was no access to downhole and along string measurements in real-time to help manage these operations. It is widely acknowledged that surface models during the actual job may bear little resemblance to what is actually occurring downhole. We will show examples of real-time downhole and along string pressure measurements utilized in a HPHT campaign of wells in the North Sea during liner running and cementing jobs and compare these results to what historically has been presented as happening downhole derived from surface measurements.

Improving Horizontal Well Managed Pressure Drilling by using a Dual Channel Drill String: Ola M. Vestavik, CTO, Reelwell, Dag Helge Breivik, OMV, Helge Rørvik, Halliburton (SPE 200506)
The presentation covers experiences and results from a horizontal well drilling trial at Ullrigg in Stavanger, Norway. The well was drilled to investigate if use of a dual channel drill string can increase the casing setting depth and improve the performance for drilling and completion of horizontal wells, especially for the Wisting field in the Barents Sea. A new type of Managed Pressure Drilling technique enables the pressure gradient in the open hole section to be held constant and independent of the circulation flow rate during drilling. This allows long horizontal sections to be drilled within a small downhole pressure window.

CBHP MPD Used to Drill Coalbed Methane Multilaterals Using Produced Water: Sagar Nauduri, Lead MPD Engineer, Martyn Parker, Jason Morris, Pruitt, Jim Abbey, Marvin Seale, Red Willow Production Company, Frank Seidel, Seidel Technologies (SPE 200515)
This presentation details what we believe to be the first use of MPD to drill coalbed methane wells in the San Juan basin (and possibly in the rest of the world). We will show how the use of MPD mitigated challenges previously seen while drilling laterals in the Fruitland Coal Formation. It will also explain how early planning between the Operating Company, MPD service provider and other vendors, along with training and staged implementation of MPD, has shown significant benefits in the drilling of these wells with considerable cost reduction for the operator.

12:30 pm  Closing Remarks & Adjournment: Brian Piccolo, Chair, IADC UBO/MPD Committee; Technical Sales Director, AFGlobal
