    5770 Impact of Monoethylene Glycol and Fe2+ on Crystal Growth of CaCO3

    Published: March 01, 2015
    Author(s): Ellen Marie Flaten, Marion Seiersten, Institute for Energy Technology; Xiaoguang Ma, Jens-Petter Andreassen, NTNU; Charlotte Aanonsen, Ralf Beck, Fjords Processing

    Calcium carbonate is one of the most abundant minerals precipitating during gas production. This work is focused on precipitation of CaCO3 in presence of Monoethylene glycol (MEG), used as hydrate inhibitor. MEG is known to affect the thermodynamics of calcium...

    5694 Evaluation of Flow Coupled CO2 Corrosion Using CFD: Kinetics and Hydrodynamics

    Published: March 01, 2015
    Author(s): Vedanth Srinivasan, ANSYS Inc

    A Comprehensive numerical model has been developed for computing corrosion rates generated by CO2 saturated aqueous solutions in an internal flow configuration. The fundamental fluid flow is characterized by numerical solutions to Navier-Stokes conservation...

    5663 The Effect of Molecular Weight Distribution on the Inhibition Efficiency Performance of Polymeric Scale Inhibitors during Retention

    Published: March 01, 2015
    Author(s): Nazia M. Farooqui, Kenneth S. Sorbie, Heriot Watt University; Luiz Palermo, Elizabete Lucas, Universidade Federal Rural do Rio de Janeiro

    Polymeric scale inhibitors (SI) used for downhole oilfield squeeze treatments must perform the dual role of inhibiting scale formation at low concentration levels (~2-20ppm) whilst giving acceptably long return curves at the wellbore; i.e. good [SI] vs. time or...

    5646 Structure and Stoichiometry of Mixed Divalent Metal (Ca2+/Mg2+/Sr2+/Ba2+) Phosphonate Scale Inhibitor Complexes for Application in Precipitation Squeeze Processes

    Published: March 01, 2015
    Author(s): S.S. Shaw, K.S. Sorbie, Heriot-Watt University

    In oilfield applications, various divalent cations are present in field produced waters, e.g. Ca2+, Mg2+, Sr2+ and Ba2+. The interaction of these cations with phosphonate scale inhibitors (SI) is important both for scale inhibition and inhibitor retention...

    5623 Study of Siderite Solubility under Extreme High Temperature and Pressure in 1 M NaCl Solution

    Published: March 01, 2015
    Author(s): Chao Yan, Paula Guraieb, Jin Huang, Ross C. Tomson, Brine Chemistry Solutions, LLC

    With the continued development of offshore production in ultra-deepwater (UDW), more and more wells are exposed to extremely high pressure and temperature (xHPHT) under anoxic condition. In order to better predict scale formation, scale solubility under these...

    5612 Reservoir Simulation and Near-Well Bore Modelling to Aid Scale Management in a Subsea Gulf of Mexico Field

    Published: March 01, 2015
    Author(s): Oleg Ishkov, Eric Mackay, Heriot-Watt University; Myles Jordan, Nalco-Champion

    This paper presents the findings of a study into the impact of reservoir flow behavior on both the scaling risk at production wells, and the options for managing this scaling risk, for a deepwater sandstone reservoir in the Gulf of Mexico. One significant feature...

    5526 Development of an Environmentally Acceptable Combined Scale/Corrosion Inhibitor for a North Sea Oilfield with High Velocity Flow

    Published: March 01, 2015
    Author(s): James Davidson, Yusuf Genty, Alyn Jenkins, M-I SWACO

    Oilfields that have limited subsea umbilicals necessitate the use of multifunctional products to maintain the field's integrity and mitigate any flow assurance and scale challenges. However, it is often the case that the active chemicals in combined products that...

    5480 Scale Deposition Control and Management in Subsea Fields

    Published: March 01, 2015
    Author(s): Hua Guan, OneSubsea

    There is general industry recognition that production chemistry is a growing concern from the conceptual design and FEED stage through to the lifetime operations. The global opportunities within the subsea market, in both greenfield and brownfield, have only...

    6132 Evaluation of Atmospheric Chloride-Induced Stress Corrosion Cracking of Austenitic Stainless Steel Canister

    Published: March 01, 2015
    Author(s): Hundal Jung, AREVA TN

    Most canisters for spent fuel storage in the US are fabricated from austenitic stainless steel. When exposed to chloride-rich atmospheres, the welded canister is susceptible to atmospheric chloride-induced stress corrosion cracking (CISCC). CISCC may affect the...

    6129 Corrosion Behaviour of Ion Vapor Deposited (IVD) and Electroplated Al Coatings on Steel Substrates

    Published: March 01, 2015
    Author(s): P. Behera, K.R. Sriraman, L. Lee, R.R. Chromik, S. Yue, S. Brahimi, McGill University

    Low hydrogen embrittling (LHE) Cd coatings are used for its inherent sacrificial protection property with high strength steel substrates. Ion Vapor Deposited (IVD) and electroplated Al coatings are potential replacements for Cd coating due to environmental...
