* The main indicator of a technology’s viability — the ultimate drilling cost (UDC) — means the total cumulative costs involved in drilling a horizontal well involving multistage fracking, per tonne of cumulative oil production.
** All equipment was manufactured as part of the national “Bazhenov” project — the Ministry of Energy of the Russian Federation having assigned national status to this project (on developing a range of domestic technologies and high-tech equipment for the viable development of the Bazhenov Formation) in 2017. The configuration of this well ensured maximum efficiency in developing non-traditional strata, and could become the main commercial technology in developing Bazhenov reserves.
*** Import substitution at this experimental well reached 95%. Russian equipment — allowing unlimited multistage fracking — was used in well stimulation at the Bazhenov Formation for the first time in 2020. Testing of the key elements of these Russian technologies — measuring while drilling (MWD), a rotation-while-cementing linger -hanger, xanthan gum-based fracking fluid, and cable-delivered feed-through (through-hole), composite, soluble and blind plugs — is now complete.
