  • A Preliminary Screening and Characterization of Suitable Acids for Sandstone Matrix Acidizing Technique: a Comprehensive Review
    Journal of Petroleum Exploration and Production Technology (2019) 9:753–778 https://doi.org/10.1007/s13202-018-0496-6 REVIEW PAPER - PRODUCTION ENGINEERING A preliminary screening and characterization of suitable acids for sandstone matrix acidizing technique: a comprehensive review Leong Van Hong1 · Hisham Ben Mahmud1 Received: 23 January 2018 / Accepted: 4 June 2018 / Published online: 11 June 2018 © The Author(s) 2018 Abstract Matrix acidizing is a broadly developed technique in sandstone stimulation to improve the permeability and porosity of a bottom-hole well. The most popular acid used is mud acid (HF–HCl). It is a mixture of hydrofluoric acid and hydrochloric acid. However, one of the conventional problems in sandstone acidizing is that mud acid faces significant issues at high temperature such as rapid rate of reaction, resulting in early acid consumption. This downside has given a negative impact to sandstone acidizing as it will result in not only permeability reduction, but can even extend to acid treatment failure. So, the aim of this study is to provide a preliminary screening and comparison of different acids based on the literature to optimize the acid selection, and targeting various temperatures of sandstone environment. This paper has comprehensively reviewed the experimental works using different acids to understand the chemical reactions and transport properties of acid in sandstone environment. The results obtained indicated that fluoroboric acid(HBF 4) could be useful in enhancing the sandstone acidizing process, although more studies are still required to consolidate this conclusion. HBF4 is well known as a low damaging acid for sandstone acidizing due to its slow hydrolytic reaction to produce HF.

From Natural Oils to Epoxy Resins: A New Paradigm in Renewable Performance Materials Dragana Radojčić†, Jian Hong and Zoran S Petrović* Kansas Polymer Research Center, Pittsburg State University, Pittsburg, KS, USA †Current address: Johnson Controls Inc., Marinette, WI 54143, [email protected] *Corresponding author: [email protected] 1 Abstract The direct conversion of natural products to useful engineering materials is desirable from both economic and environmental considerations. We are describing the synthesis and properties of 100 % oil-based epoxy resins generated from three epoxidized oils. The catalyst, tris(pentafluorophenyl)borane (B(C6F5)3) in toluene, allowed for controlled cationic polymerization at a very low concentration. Epoxidized oils (derived from triolein, soybean, and linseed oil) had varying epoxy content, rendering resins of different cross-link density. The polymerization was carried out at room temperature followed by post-curing at elevated temperature to speed up conversion. Epoxy resins were amorphous transparent glasses with glass transitions below glass transitions and hard rubbers above.

The ET in solution is studied spectroscopically, whereas solid state measurements afford information about the magnetic susceptibility or the conductivity of the given samples. The observed results are rationalized based on the chemical structures of the molecules, which have been obtained by X-ray crystallography. The crystallographically observed molecular structures as well as the interpretation based on the spectroscopic and physical measurements are backed up by DFT calculations. The measurements indicate that only weak, antiferromagnetic (AF) coupling is observed in Kuhn verdazyls owed to the low tendency to form face-to-face stacks, but also that steric reasons alone are not sufficient to explain this behavior.

We therefore designed an NMR probe that can be used to study aque- ous solutions at gigapascal pressures. Fluoride solutions were chosen for study because 19F couples to other nuclei in the solu- tions (31P and 11B) in ways that make peak assignments unequivocal. Correspondingly, NMR spectra of 19F- and 11B were 19 collected on aqueous HBF4-NH4PF6 solutions to pressures up to 2.0 GPa. At pressure, peaks in the F spectra were clear and À À À assignable to the BF4 (aq), F (aq) and BF3OH (aq) ions, and these aqueous complexes varied in signal intensity with pres- 11 À À sure and time, for each solution.

  • Investigation Into Alternative Sample Preparation Techniques for the Determination of Heavy Metals in Stationary Source Emission Samples Collected on Quartz Filters

External Editor: Ki-Hyun Kim Received: 26 September 2014; in revised form: 4 November 2014 / Accepted: 5 November 2014 / Published: 17 November 2014 Abstract: Monitoring stationary source emissions for heavy metals generally requires the use of quartz filters to collect samples because of the high temperature and high moisture sampling environment. The documentary standard method sample preparation technique in Europe, EN 14385, uses digestion in hydrofluoric acid and nitric acid (HF/HNO3) followed by complexing with boric acid (H3BO3) prior to analysis. However, the use of this method presents a number of problems, including significant instrumental drift during analysis caused by the matrix components, often leading to instrument breakdown and downtime for repairs, as well as posing significant health and safety risks. The aim of this work was to develop an alternative sample preparation technique for emissions samples on quartz filters. The alternative techniques considered were: (i) acid digestion in a fluoroboric acid (HBF4) and HNO3 mixture and (ii) acid extraction in an aqua regia (AR) mixture (HCl and HNO3). Assessment of the effectiveness of these options included determination of interferences and signal drift, as well as validating the different methods by measurement of matrix certified reference materials (CRMs), and comparing the results obtained from real test samples and sample blanks to determine limits of detection.
