The International Association of Drilling Contractors (IADC) and the Society of Petroleum Engineers (SPE) are pleased to announce the 2018 SPE/IADC Managed Pressure Drilling & Underbalanced Operations Conference & Exhibition. The conference will convene in New Orleans on 17-18 April at the Hilton Riverside Hotel.

Technologies designed to control annular pressure during drilling, inclusive of Underbalanced Drilling, Managed Pressure Drilling and Dual Gradient Drilling are being used in many forms around the world. UBD continues to maximize reservoir performance, while MPD techniques spanning onshore performance drilling and offshore deep and shallow water prospects serve to enhance drilling safety and minimize NPT. Once considered a futuristic technology, DGD is now a reality with numerous wells drilled, and many exciting prospects on the horizon.

New applications of these drilling practices take place every year, and their frequency continues to grow. This conference is a world recognized forum to help the energy industry better understand the technology and the effective, safe utilization of the various applications of UBD, MPD and DGD.

Utilizing a Fully Automated MPD System to Run and Cement 9-5/8″ Liner String in HPHT Gas Wells: Mohammad Aljubran, Drilling Engineer, Oqaili, A.H., Ezi, P.C., Saudi Aramco, Iturrios, C.O., Weatherford (SPE 190006)
Planning and design phases along with the operational sequence of running and cementing the 9-5/8 in. liner with fully automated MPD systems will be presented. Case studies will be highlighted as a means to establish lessons learned and best practices. Further details will cover the formation lithology and pore fluid nature along with the geological background related to the existing over-pressure. The pressure difficulty prediction and the methods utilized to do so will be noted to highlight the significance of the MPD utilization which allows for real-time data to be acquired regarding the formation status. Moreover, the presentation will highlight the severe issues faced when conventionally cementing this section compared to the powerful improvements gained through cementing with MPD.

Cementing Operations with Managed Pressure Assist – A Practical Approach: Robert Graham, Chief Advisor, Kelda Drilling Controls, Michael Cadd, Shell, Colin Wight, Shell Production Chemistry, Richard Sandell, Stuart Jeffries, Inam Haq, Blade Energy Partners (SPE 189996)
With MPD, the limiting factor for the well design may no longer be the window required to drill, but the window required to cement. MPD enables drilling in narrow margins, but once section TD is reached, it may not be possible to cement the casing or liner without losses. For Managed Pressure techniques to continue pushing the boundaries of what can be drilled, a robust technique for Managed Pressure Assisted Cementing is required. On a multi-well campaign in the North Sea, MP-Assisted Cementing has been applied to cement liners and casing strings in extreme narrow margins. An approach has been developed that reliably delivers cement isolation in the most challenging of environments. MP-Assisted Cementing has brought significant benefits to the design of the wells and the integrity of the cement isolation: Casing shoes have been pushed deeper, allowing strings to be removed from the design; tighter clearances can be accepted between casing OD and hole size, allowing under-reaming to be eliminated; cement can be pumped at a higher rate, improving displacement efficiency; cement jobs can be reliably performed without the risk of losses, avoiding contingency strings and costly recovery operations such as shoe squeezes and sidetracks. This paper describes the procedures that have been developed and the benefits of MP-Assisted Cementing, including key considerations and best practices during both planning and execution. This presentation describes the procedures and best practices developed during a multi-well campaign in the North Sea to enable loss-free cementation of strings in extreme narrow margins

Session Chair: Dennis Moore, Senior Technical Consultant, Marathon Oil Company

Eliminating Losses in Permian Basin Midland Basin Wells through Managed Pressure Drilling and Cementing: Hayes Thibodeaux, Drilling Engineer, Joe Williams, Nick Duhe, Jordan Milazzo, Chevron, Matthew Kvalo, Oriane Deplaude, Nathan Vargas, John Hobin, James Jesudas, Jenny Clements, Schlumberger (SPE 189997)
A case study will be presented where MPD and Managed Pressure Cementing enabled the operator to effectively drill, case and cement across the troubling Sprayberry Shale in the Permian’s Midland basin.

Managed Pressure Drilling in Deepwater Brazil Presalt Severe-Loss Scenario: Thiago Pontes, Account Representative, Fernando Barbosa, Silvio Cosendey, Halliburton (SPE 189998)
The presentation is based on three wells drilled with the improved MPD technology in a Brazil deepwater pre-salt area in a carbonate scenario with very severe losses. This new MPD software technology differed from previousy systems so all personnel had to be trained to work with MPD. Then the equipment was mounted on two separate rigs, operational decisions were made to use best practices, and operations started. Before beginning drilling using the MPD technique, all crew members were familiarized with their operational roles, valve alignment, procedures, etc. The presentation concludes with results of operational procedures, cost savings, software/algorithm improvements, and lessons learned.

First Field Use of Electric Servo Actuated Choke Designed for Managed Pressure Drilling: Martyn Parker, Chief Operating Officer, Sagar Nauduri, Micah Spahn, Pruitt Optimal, Ryan Klemetson, Tolomatic (SPE 190010)
During our MPD choke system factory acceptance program, we quickly learned that this new actuator has the ability to perform very accurate and responsive pressure control to quick changes in pressure demands based on changes in both set point and flow. This control was further demonstrated during our initial MPD operations where we demonstrated pressure control tracking at lower flowrates when compared to worm gear driven chokes. The use of this new actuator technology greatly increases the precise control of drilling chokes in MPD applications whilst also reducing the potential failure points in the actuator giving enhanced uptime and life cycle and minimizing the need for routine maintenance. The design also lends itself to more compact MPD equipment design.

Optimizing MPD Performance in Highly Permeable Exploratory HPHT Reservoirs: Dealing with Human Factor and Technology Limitations: Sunday Awe, Senior Well Engineer, Ayodele Akinfolarin, Adeyemi Erinle, Timothy Ibrahim, Shell Petroleum Development Company (SPE 190012)
MPD application was used for drilling a narrow margin HPHT exploration well. The first deployment encountered a kick as a result of bottom-hole pressure dips below the set point and pore pressure. The team normalized the indication of kicks as a result of over reliance on MPD. To manage the human factor contribution, procedures and training exercises were conducted. An improved bottom-hole management was achieved by replacing the conventional APM tool with an advance model. The clearer understanding of BHP behavior during the various pumps-on/pumps-off process enabled the achievement of BHP values within a range that allowed safe drilling operation in the second MPD deployment are also enumerated.

3:45 pm  Technology Advances
Session Chair: Frédéric Jacquemin, Director Sales Europe & Africa, Pacific Drilling

A New Method for Enhanced Continuous Circulation Automation: Rachel Johnson, Global Product Champion, Adam Milne, Halliburton, Claudio Molaschi, Eni E&P (SPE 189999)
A common form of continuous circulation uses a manifold connected into the rig’s standpipe that diverts flow to and from the top drive to a sideport on a sub threaded into the top of each drilling stand. The sub contains internal flapper valves that enable flow through the sideport, automatically isolate the top drive, and provide circulation downhole while making or breaking a connection. This system has been used to drill approximately 125 wells in the last 10 years in global applications ranging from land to offshore floating installations. A semi-automated process was developed which enhances the current manual process. This presentation discusses the case study of both a prototype tool that was assembled and successfully tested in November 2016 in the Val D’Agri oilfield region in southern Italy, and a commercial tool that has been developed and deployed based on lessons learned, expanding the overall service offering capabilities and offering a significant process and safety improvement.

RCD Element Design Optimization for MPD Operations: Shailesh Mirasdar, Project Engineer, Pavel Chaguine, Kedar M Deshpande, Al Alajbegovic, Weatherford (SPE 190011)
MPD provides ability to control and finely tune Bottom Hole Pressure (BHP) by introducing and controlling backpressure of wellbore returns. In addition, RCD diverts wellbore returns away from the rig floor, thus improving safety and addressing environmental concerns associated with mud spills. RCD element is exposed to both internal and external changing loads and hence needs to be designed optimally to reduce nonproductive time (NPT) and conduct safe MPD operations. The present work focuses on numerical simulations to improve the RCD element functional longevity by first comparing numerical results with existing laboratory test data and followed by enhancements to RCD element shape through numerical optimization. FEA studies predicted a good match with laboratory measurements. This work elucidates use of advanced computational techniques for RCD element design optimization within given operating constraints.

Managed Pressure Drilling Optimized Design and Future Strategy: Jason Custer, Mechanical Engineer, Robert van Kuilenburg, Noble Drilling, Austin Johnson, AFGlobal, Svein Hovland, National Oilwell Varco (SPE 190003)
Noble Drilling has embarked on an innovative, cost effective, and efficient approach to upgrade its fleet to be MPD enabled. The core of the approach is an integrated MPD package that can be transferred from rig to rig with minimal time and effort. Noble is working with multiple vendors to integrate the drilling control system with the MPD control system, thus enhancing the efficiency of rig operations. This innovative concept will bring improved efficiency for every well drilled by Noble. Fully integrated MPD with rig drilling control systems is a key step in bringing Noble closer to fully automated drilling.

8:15 am  Well Control Considerations
Session Chair: Andre Alonso Fernandes, Chair, IADC UBO/MPD Committee; Technical Advisor, Petrobras

Advancing the MPD Influx Management Envelope (IME): A Comprehensive Approach to Assess the Factors that Affect the Shape of the IME: Harshad Patil, Senior Project Engineer, Terry Lamar Ponder, Chevron (Retired), Maurizio Arnone, Weatherford, Don Hannegan, Weatherford (Retired) (SPE 189995)
Advancements to the methodology described in SPE 170684 to develop an influx management Envelope (I6ME) will be presented. It illustrates the methodology to adopt factors such as, “maximum flow rate for circulating influx”, “how to define the shape of the IME when shoe strength is lower than the RCD limit,” “Shut in scenario during circulating of influx,” “the effect of mud compressibility due to added back-pressure on the IME,” etc. The end result of the modified IME is intended to be a design tool for the field supervisors to make robust decisions on whether it will be safe to circulate influx through the MPD system or conventionally.

Condition Monitoring System for the Sealing Elements of an Active MPD Wellbore Sealing Device: Brian Piccolo, Technology Sales Director, Austin Johnson, Justin Fraczek, AFGlobal
A system has been developed to condition monitor the sealing elements of an active MPD wellbore sealing device. This system tracks key parameters over time to give the rig crew insight on how much operating life a seal assembly has remaining. The rig crew can determine graphically whether a substantial portion of seal element life remains or a limited amount. This information enables a rapid and objective assessment of the remaining seal element life. Subsequently, the agreed upon operating window of the MPD system to conduct higher pressure influx circulations can be increased.

Advancing the Mud Gas Separator Sizing Calculation: The MPD Perspective: Kedar Deshpande, Engineering Manager, Harshad Patil, Terry Ponder, Chevron (Retired), Maurizio Arnone, Weatherford (SPE 190008)
Presentation will underscore importance of liquid and gas handling capacity of the MGS w.r.t safe MPD Influx Management Envelope (IME) with specific examples. Traditional MGS calculations will be presented and possible advancements will be mentioned to account for gas expansion correctly. Advanced computational techniques (CFD) will be utilized to study multiphase flow of liquid & gas through MGS and several sensitivity studies will be presented for given operating range. Comparison will be presented using current traditional methods, CFD approach and modified friction calculations, advantages and drawbacks will also be mentioned for these approaches.

Experimental Study on Riser Gas Expansion and Unloading: Omer Kaldirim, Graduate Research Assistant, Dr. Jerome J. Schubert, Texas A&M University (SPE 190004)
Riser unloading is an important subject, which is caused by the uncontrolled expansion of gas kicks. This paper provides information on an experimental study on riser gas expansion and unloading using a scaled riser model at the dual gradient drilling laboratory at Texas A&M University. The experiments simulate and log gas expansion and riser unloading for various mud viscosities and pipe scales. The disproportion of the atmospheric pressure and the scale of the model is mitigated using vacuum pumps. The study demonstrates the effect of uncontrolled expansion in an open loop system and unloading.

10:15 am  Coffee Service & Exhibit Viewing

10:45 am  Exploring Dynamic Influx Management and Riser Gas Handling: Are We Past the Theory Stage?
Moderator: Pat Brand, Executive VP Operations, Blade Energy Partners
The advantages of dynamic influx control over conventional well control and handling of riser gas events has been discussed for several years.  Managed Pressure Operations enhance the primary wellbore barrier in terms of adding additional means to control the wellbore pressure profile, enabling to regain overbalanced condition much faster and in a safer manner than conventional drilling. This allows to deal with influxes and riser gas events without requiring to activate the secondary barrier every time.  The panel will discuss the current status of dynamic well control from both a practical application and a regulatory position and the current barriers for the adoption of the technology.  The panel will also discuss their vision on the future developments and adoption of dynamic well control and MPD riser gas handling.

1:30 pm  Training & HSE Risks
Session Chair: Brian Grayson, Director, Pressure Control Systems, Weatherford

How Can Good Be So Bad? Kim Laursen, Operations Manager, Evelyn Baldwin, Maersk Training
With the implementation of new technology on deep-water units, there have been huge strides made towards a safer and more efficient way of drilling wells. However, with the introduction of these advancements different challenges also arise. In fact, as new technologies are introduced, the more important team skills, or Crew Resource Management becomes. With new technology, teams change and confidence in the new roles and responsibilities can suffer, which can effect communication and ultimately decision making. Piggy backing off the success of the aviation industry, at Maersk Training, we’ve found an efficient way to ensure that teams utilize each other to mitigate human error and more fluently adapt new technologies into their operations is by integrating three pieces of training. Specifically, we focus on merging high fidelity simulations with technical training and Crew Resource Management. This presentation highlights how to best train crews going into operations with MPD.

Avoiding Software Risks for MPD Control Systems: Mirnes Alic, Senior Project Engineer, Cesar Carvalho, DNV GL
Drilling control systems have become very complex in order to reach sources of oil buried under challenging formations. New control strategies are taken into use and the complexity of these systems quickly increases as they include downhole pressure control, contingency detection, critical safety features, failure handling etc. Hardware-In-the-Loop (HIL) testing, as a test methodology for systematic testing of control system design philosophy, functionality, and failure handling capability contributing to increased quality, safety and reduced costs when installing MPD systems and during the life cycle of the vessel will be presented. By using a virtual test-bed it is possible to verify and validate the MPD control system software and integration with other systems without risk to man, vessel, equipment, or environment.

2:30 pm  Coffee Break & Exhibit Viewing

2:45 pm  Deepwater Applications
Session Chair: Andre Alonso Fernandes, Chair, IADC UBO/MPD Committee; Technical Advisor, Petrobras

Dual-Gradient Drilling of Deepwater in South China Sea: What is the Well’s Maximum Measured Depth and How to Improve It: Jun Li, Hui Zhang, China University of Petroleum, Beijing, Xin Li, China University of Petroleum, Shidong Ding, Qian Tao, SINOPEC Research Institute of Petroleum Engineering, Beijing (SPE 190009)
In this study, a model to predict the maximum measured depth (MMD) of extended-reach well (ERW) by DGD in deepwater is presented. The prediction model is established based on the dynamic pressure balance of bottom hole. Two DGD modes, including subsea mudlift drilling and hollow glass spheres, are analyzed and their prediction models of MMD are established respectively. An offshore ERW in South China Sea is analyzed. Results show that the ERW’s MMD first increases and subsequently decreases with the increase in drilling fluid density, and the DGD mode is conducive to expanding the MWW of ERW in deepwater.

MPD- Overlooked Factors that Impact Annular Pressure Control with High-Solids Concentration Drilling Fluid Systems in Narrow Window Wells: Julian Hernandez, Project Engineer, Maurizio Arnone, Juan Valecillos, Weatherford (SPE 190001)
Having control over the challenges that represent these additional factors’ impact on the downhole pressure behavior, leads to an even further optimized MPD operation than what is often accomplished, especially in the more demanding environments of shallow offshore, deepwater and/or HP/HT wells.

3:45 pm  Closing Remarks & Adjournment

Using Real-Time Fluid Properties Data to Provide Accurate Results for Managed Pressure Drilling and Improve Drilling Control: Odai Elyas, Petroleum Engineer, Abdullah Al-Yami, Salem Gharbi, Mohammad Al-Jubran, Saudi Aramco (SPE 190007)
The big benefit to Saudi ARAMCO operations in MPD comes from acquiring real-time data for fluid properties like density and rheology, at a high frequency. In the past, MPD was failing in our operations due to lack of data accuracy and real time data causing incidents such as kicks, losses and stuck pipe. In this paper, we will demonstrate the steps taken to obtain real-time data measurements of the properties and the operational details that led to the improved performance of MPD.
