Polyolefin catalysis of propene, 1-butene and isobutene monitored using hyperpolarized NMR

Autor: Hamidreza Samouei, Christian Hilty, Yaewon Kim

Publikováno v: Chemical Science

Polymerization reactions of the dissolved gases propene, 1-butene, and isobutene catalyzed by [Zr(Cp)2Me][B(C6F5)4] were characterized using in situ NMR. Hyperpolarization of 13C spins by the dissolution dynamic nuclear polarization (DNP) technique p

Dynamic Nuclear Polarization Using 3D Aromatic Boron Cluster Radicals

Autor: Rebecca M. Kubena, Julia M. Stauber, Christian Hilty, Hamidreza Samouei, Pierce Pham, Alexander M. Spokoyny, Yaewon Kim, Jonathan C. Axtell

Publikováno v: J Phys Chem Lett

A set of two dodecaborate [B(12)(OR)(12)](1−) radical cluster anions containing a dense layer of fluorinated end-groups provide nuclear spin hyperpolarization via the dissolution dynamic nuclear polarization (D-DNP) technique. We show that these cl

NMR Investigation of Viscoelastic Surfactant Compatibility with Corrosion Inhibitors

Autor: Hisham A. Nasr-El-Din, Hamidreza Samouei, Salar Afra

Publikováno v: SPE Journal. 26:1250-1260

Summary Viscoelastic surfactants (VESs) have been successfully applied as acid-diversion fluids. However, high-temperature (>200°F), interaction of VES with metallic cations, alcohol-based additives, and chelating agents all interfere with the appar

Novel Class of Retarded, Newtonian, Single-Phase HCl-Based Stimulation Fluids: A Laboratory Characterization

Autor: Hamidreza Samouei, Igor Ivanishin, Abdollah Orangi

Publikováno v: Day 1 Wed, February 23, 2022.

Novel retarded acids were designed and evaluated by measuring their dissolution and corrosion rates in the laboratory at a temperature of 250°F. Results indicate that depending on the type of the retarder, the acid solutions containing 15 wt% HCl re

Uncovering Mysteries of Waxphaltenes: Meticulous Experimental Studies of Field and Lab Deposits Unveil Nature of Wax-Asphaltene Intermolecular Interactions

Autor: Amir Mahmoudkhani, Janaina I. S. Aguiar, Hamidreza Samouei

Publikováno v: Day 2 Tue, December 07, 2021.

In recent years, the utilization of modern sampling tools provided access to the field deposits from several offshore and onshore wells producing asphaltenic crudes. Compositional analysis of field deposits revealed the presence of asphaltenes and wa
