08.30-09.30       UBD or MPD: An Engineering Choice Based on Intent (SPE/IADC 130563)
                        Moderator: Don Hannegan, Weatherford International Ltd.

• Ken Malloy, Staff Consultant, Stress Engineering Services
• Sara Shayegi, Drilling Advisor, Hess Corporation

Often times reservoir and drilling engineers are faced with the decision on how best to construct a well to exploit zones of interest while seeking to avoid drilling problems that contribute to reservoir damage or cause loss of hole. The decision to pursue either UBD or MPD operations is based on the intent of applying the most appropriate technology for the candidate and entails either an acceptance of influx to the surface or avoidance of influx into the wellbore. The merits of each technology will be described to aid in the decision-making process.

Managed Pressure Drilling in the Gulf of Thailand Enables Talisman to Optimize Drilling and ECD Management and Avoid Losses in Depleted Reservoirs
Paul Fredericks, Greg Garcia and Ossama Sehsah, At Balance (SPE/IADC 130316)
Talisman Malaysia successfully applied MPD in a Gulf of Thailand field characterized by narrow pressure margins caused by unstable coals and depleted reservoir sands. Since 2007 Talisman has drilled 6 wells with MPD. Comparison data from wells drilled in 2009 with and without MPD proved its ability to effectively drill high angle sections through highly depleted reservoirs without incurring losses or sacrificing drilling efficiency. An automated MPD system enabled Talisman to lower the static mud weight by a significant amount and manage the ECD with no loss of stability in the coal seams or mud in the depleted sands.

Experiences and Results with a New Automated MPD System while Drilling and Cementing Liner in an Onshore Depleted Gas Field
Paul Fredericks and Ossama Sehsah, At Balance; and Julio Montilva and Phil Vogelsberg, Shell Exploration & Production Company (SPE/IADC 130319)
Shell has developed a unique solution to eliminate lost circulation, stuck pipe, and unplanned influx while drilling depleted gas fields. Two complementary technologies – liner drilling and automated MPD – have been used to drill tight pressure margins with statically underbalanced mud. In two recently drilled wells Shell was able to manage pressure during periods of high drill gas and avoid the cost of a contingency 5-1/2” liner drilling operations. During one of those wells, Shell used automated MPD for the first time to manage BHP while cementing drilled-in production tubing.

10.15-12.15             Total Systems & Reservoir Characterization
Moderator: Sara Shayegi, Hess Corporation

“Drill thru the Limit” Concepts and Enabling Tools
Don Hannegan, Weatherford International Ltd.
By encouraging drilling decision-makers to consider the totality of the circulating fluids system when designing the fluids and well construction programs, this presentation speaks to an extension of MPD's pressure vessel mentality. Beyond MPD's primary focus of maintaining EMW within drilling windows, this method places a balanced emphasis upon simplifying the casing program, achieving TD with a deeper, larger reservoir access, and doing so with a less expensive and/or most readily available drilling fluid.

Variable Rate UBD Production Data Facilitates Reservoir Characterization
Steve Nas, Sunil Lakshminarayanan, Jaime Villatoro, Said Boutalbi and George Stewart, Weatherford International Ltd. (SPE/IADC 130309)
The utilization of underbalanced drilling data to improve field productivity and recovery via real time reservoir characterization is described. Unlike conventional well testing, UBD data makes it is possible to identify a permeability distribution for the entire reservoir. The major focus of the presentation is the technique used in the characterization tool to interpret the production associated with the drawdown, and some of the case studies and results.

MPD Candidate Identification: To MPD or Not To MPD
George H. Medley and Sagar Nauduri, Signa Engineering Corp.; and Jerome J. Schubert, TAMU (SPE/IADC 130330)
The biggest unanswered question for many projects is whether or not to utilize MPD techniques. Even with all the advancements in science and technology and increased availability of equipment and expertise, until now the industry lacked a Candidate Identification Mechanism (CIM) developed exclusively for MPD and its applications. A new MPD CIM described here considers all available engineering data and economic aspects of the given project and determines if MPD is a solution. This CIM was developed through interaction between the petroleum industry and the Petroleum Engineering research program at a major US University.

Managed Pressure Drilling Brings Added Value to Production Casings Cementing Operations Increasing Success Rates and Quality in HPHT Fractured Narrow Window Wells
Leiro Medina, Fernando Gallo, Hermogenes Duno, Juan Carlos Beltran and Corrado Lupo, Schlumberger (SPE/IADC 130313)
Recommended operational procedures and recommended practices to integrate the MPD technique along with conventional cementing operations are presented. An example is given of nitrified pre-fluxes in cementing jobs for low pressure wells scenarios and a series of typical case histories of HPHT wells where a 5” liner was ran trough a 7” liner 38# followed by an open hole of 5 5/8” at 6000 meters MD. The annulus between the 5” liner and the 7” liner 38# is very small, this condition associated with a narrow mud weight window.

13.30-15.00       Hydraulic Modeling
                        Moderator: Kristin Falk, Ocean Riser Systems AS 

Understanding Multiphase Flow Modeling for N₂ Concentric Nitrogen Injection Through Downhole Pressure Sensor Data Measurements While Drilling MPD Wells
Juan Carlos Beltran, Corrado Lupo, Leiro Medina, Hermogenes Duno, Fernando Gallo, Jose Tang, and Jimmy Rojas, Schlumberger-Optimal Pressure Drilling; Hernan Melgares, Schlumberger D&M; Efrain Rodriguez, Schlumberger IPM; and Jorge Bedoya and Gustavo Puerto, Blade Energy Partners (SPE/IADC 130324)
The ECD calculation in an MPD operation is not the solely objective of using a complex modeling system. Today’s downhole drilling tools technology makes available a variety of sensors capable of measuring actual downhole pressure values. Prediction of flow behavior is also an important step that will increase the ability of monitoring and keeping efficient hole cleaning, cutting transport and heat transfer efficiency, which are critical for all multiphase drilling operations. Actual measurement of downhole equivalent circulating density becomes now a critical new calibration value to compare hydraulic models performance and approximation to reality.

Knut Steinar Bjørkevoll and Svein Hovland, SINTEF Petroleum Research; Ingvill Barr Aas, Halliburton; and Elin Vollen, Statoil (SPE/IADC 130311)
An advanced real time dynamic flow and temperature model was used to optimize and control challenging MPD operations on Gullfaks C in the North Sea. This paper addresses model specific challenges, analyses differences between model calculations and downhole pressure data, and discusses how to bring modeling further in accordance with future operational needs.

A Simplified and Highly Effective Method to Identify Influx and Losses during Managed Pressure Drilling Without the Use of a Coriolis Flow Meter
Don Reitsma, At Balance Americas LLC (SPE/IADC 130312)
The constant bottomhole pressure (BHP) calculation and control system of the Dynamic Annular Pressure Control (DAPC) system has been modified to provide an effective means of accurately detecting influxes without a flow meter, controlling the unplanned flow from the well, and reducing the influx volume. Recent tests performed at the Louisiana State University PERTT facility and field tests proved the system’s ability to identify unplanned flow events reliably. Test results will be shown and ways in which the system can easily be installed on a rig will be discussed.
