The initial flow rate exceeded 120 tonnes of oil per day — 6 times higher than the productivity of previously built wells in that area.
The new well has become one of the most complex drilling targets ever dealt with in Russia.
Combining a number of unique technical characteristics the borehole’s directional difficulty index stands at 6.69, compared to an industry average of 6, running at a depth of around 800 m the borehole’s footage drilled through the oil-bearing strata reaches 7.7 km.
Vadim Yakovlev, Deputy CEO for Exploration & Production of Gazprom Neft, said:
- The new well confirmed the potential of developing Karabashsky license areas with total potential resources of 420 mtoe, allowing us to move on to the next phase of the project as well as to deploy the technology used here in developing other hard-to-recover reserves
Implementation of the project and obtained commercial inflows confirmed the commercial development potential of the field, initial reserves in place of which stand at about 200 million tonnes of oil.
Eurotec-Yugra has completed well testing by the Q2 of 2021.
On the basis of the data obtained, a field development plan will be prepared.
Engineering solutions with confirmed efficiency during this project will be replicated in the development of neighbouring deposits and other assets of the joint venture between Gazprom Neft and Repsol in the Karabashsky blocks.
