  • Distinguished Lecture: What Happens When Heavy Oil and Solvent Mix?

    Monday, February 10, 2020, 5:15 PM - 7:15 PM MT
    ABSTRACT Heavy oil is a significant global resource but is challenging to recover and process due to its high intrinsic viscosity. One method to reduce its viscosity is to add solvent. Mixing heavy oil and solvent sounds simple in principle but can lead to surprisingly complex results. Multiple phases may form and the viscosity of these phases can span five orders of magnitude. Hence, it is vital to accurately measure and predict the phase behavior and properties of these mixtures in order to appropriately design and operate solvent-based heavy oil processes. The purposes of this presentation are to: 1) illustrate the potential outcomes when solvent is added to heavy oil; 2) highlight the current strengths and limitations in modeling these outcomes. In particular, two aspects of these mixtures are considered: phase behavior and viscosity. First, the phase behavior of mixtures of heavy oil and light n-alkanes is reviewed, including vapor-liquid boundaries, liquid-liquid boundaries, and asphaltene-rich phase yields over a wide range of pressures, temperatures, and compositions. The nature of the heavy liquid phase (from dispersed glassy particulates to a viscous liquid) is examined and the kinetics of the phase change is discussed. The performance of equations of state in modeling the phase behavior for mixtures of heavy oil and solvent is assessed. Second, the effect of solvent addition on heavy oil viscosity is shown and different approaches for predicting the viscosity of these mixtures are examined. The data and modeling approaches shown in this presentation are the product a decade of research and have application in many industrial processes including in situ recovery processes, oil sands froth treatment, solvent deasphalting, and flow assurance. The current status of heavy oil/solvent processes is reviewed with a focus on the role of phase behavior and properties in selected applications is discussed. The one takeaway idea is that phase behavior can be complex; it can make your project if understood and break it if not. BIOGRAPHY Harvey Yarranton is a Professor of Chemical and Petroleum Engineering at the University of Calgary and is the NSERC Industrial Research Chair in Heavy Oil Properties and Processing. Previously, he worked in petroleum engineering at Dome Petroleum Ltd. and Amoco Canada Ltd. His research interests include the phase behavior and properties of heavy oils and solvents, the fundamentals and treatment of water-in-oil emulsions, and oil sands extraction and froth treatment. He authored or coauthored more than 90 journal papers. He holds a B.Sc. (1985) and a Ph.D. (1997) in Chemical Engineering from the University of Alberta. He is an associate editor of SPE Reservoir Evaluation and Engineering and is the recipient of a 2010 SPE Outstanding Service and 2016 “A Peer Apart” awards.

  • Distinguished Lecture: “Reservoir Engineering While Drilling” in Horizontal Wells

    Tuesday, March 10, 2020, 5:30 PM - 7:15 PM MT
    ABSTRACT Over the past forty years, steering a horizontal well in conventional reservoirs has evolved from geometric to geological to structural and now productivity steering. This talk is aimed to summarize the evolution of wellbore steering, the impact of logging-while-drilling on well and reservoir performance, and the real-time application of reservoir engineering fundamentals while drilling these horizontal wells. The talk also addresses questions like: • What is the deliverability (PI, Q) of the horizontal drilled interval? • What is the impact of changing wellbore trajectory while drilling (sensitivity analysis) on PI? • How can we steer a horizontal well to maximize productivity and/or recovery and/or minimize flow assurance issues? BIOGRAPHY Shahid Azizul Haq is Reservoir Engineering Advisor in Schlumberger. He is subject matter expert on formation testing (FT), production logging (PL) and pressure transient analysis (PTA). He has been with Schlumberger for more than 30 years and most of his firsthand experience of FT/PL/PTA stem from working in Middle East (Syria, UAE, Saudi Arabia & Qatar), an environment rich in horizontal wells. For the past 10 years, Shahid is working as the Global Reservoir Domain Head for Schlumberger Drilling & Measurements where his primary role is to manage the development of new formation testing and reservoir engineering techniques/workflows/answer products for the "while drilling" environment. He has pioneered the workflow of Real Time Productivity Steering also known as RTPS, a key enabler for the real-time application of reservoir engineering while drilling horizontal wells. Shahid has co-authored 16 papers (out of his 26 papers) focused on horizontal wells either regarding formation testing or production logging or productivity steering. He holds BS and MS degrees in petroleum engineering. Shahid has been a member of various SPE, SPWLA and IPTC program committees as well as the Editorial Review Committee for SPE Reservoir Evaluation & Engineering. Shahid received 2017 SPE Regional Service Award for Gulf Coast North America Region.
