The advantage of using the Helium survey in an virgin stage exploration is the speed and reduced cost of results, so it is possible to obtain data about the field that will direct and compliment the other acquisition methods, in order to reduce the costs of the exploratory process.

 

      This case study is about a virgin area with high potential of oil and gas exploration in the Jurassic terrigenous sediments in the region of Verkhneuhudoseisky in Western Siberia. The project was done for a division of Gazprom, Gazprom Dobycha Noyabrsk, in 2009. The purpose was to map the structural traps of hydrocarbons. The whole area covered 1432 km2. 2D Seismic survey was done ​earlier and continued until the Helium survey. Integrating the results of the seismic and Helium survey, it is possible to observe a strong correlation between both in setting traps (see Testimonial 3).

 

      On the right, the map is showing in detail a trap of 18 km2 (purple contour), evidencing this correlation. In blue, the trap contour defined by seismic and in purple, defined by Helium. The black triangle marks the site of drilling recommendation (sweet-spot), a region of high Helium flow. Altogether, AGI recommended 10 points for drilling in ideal spots for hydrocarbon exploration.
