PARAMETRIC DRILLING OF WELL NO.1 BAGENOVSKAYA

Drilling of Bazhenov well No.2 (3202,8 m of total depth) was completed

Thanks to an integrated approach to drilling and use of new state-of-art drilling rig, the well was drilled in the shortest possible time - for less than 5 months. In total, considering the core collection, there was drilled 643,8 m, the intervals of opening of Bazhenov, Abalak, Tyumen suites and pre-Jurassic base were drilled with continuous core sampling

The core samples from the sediments of Bazhenov-Abalak structures were collected into the fiberglass core sampling tubes. The results of the collected material studies demonstrated that the most promising in terms studying the hydrocarbon potential are the sediments of Bazhenov-Abalak structures, layer J2 of of Tyumen suite, and volcanogenic-sedimentary strata of pre-Jurassic basement

The following characteristics were found out in Bazhenov suite sediments: the anomalous enrichment with organic material, rich generation potential, abnormally high saturation of the rocks with free hydrocarbons, availability of carbonate component, hard skeleton, increases heating temperature.

There are some zones specified with microinterbedding in the cross-section, that provides an opportunity to increase the porosity & permeability by means of artificaila cracking induction.
