  • Technical reports on ISC: 37 (for more than 18 projects, both pilots and commercial projects)
  • Publications on ISC process/projects: 20
  • ISC international consultancy work: Ecuador, India, Malaysia, Japan, China, Russia, Kazakhstan, Romania, Brazil, USA, Colombia and Argentina; World Bank ISC expert in 1986 for Videle-Balaria commercial ISC projects in Romania; ISC expert for India in the period 1991-1996 and in 2015
  • Consultancy in North America: Amoco, USA, Oracle Oil, USA, ARC (1993)
  • ISC related patents: 9
  • Instrumental in developing the theory and practice of commercial exploitation of heavy oil reservoirs by ISC using the peripheral line drive operation starting from the uppermost part of the structure; today, this is the preferred mode of exploitation, worldwide.
  • Instrumental in the development of the short-distance oil displacement (SDOD) processes: Toe-To-Heel Air Injection (THAI), and catalytic THAI (CAPRI), in a long cooperation (1992-2003) with University of Bath, England. THAI and CAPRI are new recovery processes for heavy oil recovery. Also, developed the Toe-To-Heel Waterflooding (TTHW) process and investigated the Toe-To-Heel Steamflooding, which, at this time, is still under development

  • Established a more general equation for the calculation of the apparent hydrogen-carbon ratio (H/C ratio) from the composition of the produced gases of an ISC pilot. This takes into account the gases which are non-participating in the combustion but are produced with those participating, such as hydrocarbon gases, hydrogen, some CO2, etc.
  • Highlighted the strong positive effect of high reservoir temperature on the applicability of ISC. This is directly related to the possibility of using small air fluxes (low air injection rates) and to the possibility of using the peripheral line drive operation starting from the uppermost part of the structure
