  • Carbon Black and silica as reinforcers of rubber polymers 
    Semaan, Mars E.; Quarles, C.A.; Nikiel, Leszek (2016-04-18)
    We have used Doppler broadening spectroscopy to investigate the effects of filling various rubber polymers with different amounts and types of carbon blacks and of silica. Carbon Black has important reinforcing properties ...
  • Comparison of various poststack enhancement techniques 
    Semaan, Mars E.; Lee, Shu-Schung; Chen, Thomas C. (Society of Exploration Geophysicists, 2018-05-08)
    Lee, S. S., Semaan, M. E., & Chen, T. C. (1990, January). Comparison of Various Poststack Enhancement Techniques. In 1990 SEG Annual Meeting. Society of Exploration Geophysicists.
  • Doppler broadening spectroscopy of carbon black and carbon black-filled rubbers 
    Semaan, Mars E.; Nikiel, Leszek; Quarles, C.A. (2016-04-18)
    We have used positron annihilation Doppler broadening spectroscopy to investigate the effects of filling various rubber polymers with different amounts and types of carbon blacks. The results show direct correlation between ...
  • Impact of an integrated seismic data processing approach 
    Semaan, Mars E.; Murhantoro, Eddy; Achmad Bermawi, Maryanto; Subianto, Budi; Santoso, Hari (2018-05-08)
    Results from an integrated seismic data processing approach are presented. The following five industry known techniques are used: The first is pre-stack processing and imaging that resulted in properly placed structures ...
  • Implementation of the optical stack method 
    Semaan, Mars E.; Arnold, Richard H. (2018-05-08)
  • A model for low energy thick-target bremsstrahlung produced in an SEM 
    Semaan, Mars E.; Quarles, C.A. (American Physical Society, 2018-05-08)
    A model for thick-target bremsstrahlung has been developed based on the approach used by Storm ( E. Storm, Phys. Rev. A.5, 2328 (1972).)and Ambrose et al. ( R. Ambrose, D. L. Kahler, H. E. Lehtihet and C. A. Quarles, Nucl. ...
  • Positron annihilation doppler broadening spectroscopy of carbon black and carbon black-filled rubber polymers 
    Semaan, Mars E.; Quarles, C.A. (American Physical Society, 2018-05-08)
    We have used positron annihilation Doppler Broadening Spectroscopy to investigate the effects of filling various rubber polymers with different amounts and types of carbon blacks. The S parameter was measured for a wide ...
  • Positron Annihilation Lifetime Spectroscopy of Carbon Black- and Silica-Filled Rubber 
    Semaan, Mars E.; Quarles, C.A.; Urban-Klaehn, J. M.; Gerspacher, M.; Nikiel, Leszek (2016-04-18)
    Lifetime spectroscopy has been used to investigate different grades of carbon black (CB) and silica mixed into a variety of rubbers as a function of CB or silica loading. The spectra were analyzed into three lifetimes. The ...
  • Quality data at a reduced price 
    Semaan, Mars E.; Bee, Michel F.; Gerard Dugourd, Maryanto; Sentani, Eddy A. (2018-05-08)
    A case history of an economical 3-D land seismic survey acquisition and processing is presented. The survey was acquired by Caltex Pacific Indonesia (CPI) over the Pedada field in Central Sumatra. The field has a complex ...
