Innovation projects valuation using options theory

It is noted, that the investment projects, related to the scientific research and new developments, are always realized in conditions of high uncertainty and inevitable risks. The use of the option theory is proposed for estimation the cost of research projects. An example of such an assessment, using the method of decision tree, is given. It is concluded, that the proposed method allows to exclude from consideration known unrealizable scenarios, but to take into account the cost of technological breakthroughs capabilities.

Development of abandonment fluid applied downhole while abandonment of offshore wells

First experience in activities relating to the abandonment of offshore wells in the oilfields operated and developed by Vietsovpetro JV has shown that abandonment fluids traditionally applied do not meet the Safety and Environment Regulations. This is because the applied solutions lose their technological properties during long-term abandonment and corrosivity increases due to biological degradation of reagents included in their composition. The paper discusses the development results of a new composition of the abandonment fluid applied downhole while abandonment of the offshore wells.
