Analysis of geological structure and efficiency of horizontal technology application on Novo-Suksinskoye field

Authors: R.T. Shakirova, V.Yu. Kondakova, D.S. Danilov (TatNIPIneft)

Bobrikov pool of Novo-Suksinskoye oil field has complex geological structure and unique characteristics: presence of all three formations C1br13, C1br12, C1br11 and at the same time insignificant compartmentalization due to junction and high oil-bearing thickness. These factors are favourable for construction of horizontal and multilateral horizontal wells. Efficiency analysis showed that drilling of multilateral horizontal wells on the field is effective if horizontal section of the wellbore passes through the most permeable part of the formation at the distance of at least 5-10 meters from oil-water contact.
