The Tazovskoye oil & gas condensate field forms part of Gazprom Neft’s promising production cluster in the Nadym-Pur-Taz region in the north of the Yamalo-Nenets AO.
The Tazovskoye oil & gas condensate field’s reserves occur in an «oil rim - a thick layer of oil between a «gas cap» and a water horizon.
The field is marked by low reservoir temperatures, a high gas factor, and a predominance of high-viscosity oil.
Drilling is undertaken in an ultra-thin stratum (of about 8 m in height) demanding high-tech downhole equipment as well as pinpoint accuracy.
Multi-branched (multi-hole) and multilateral wells, with a horizontal section of more than 2,000 m (including fishbone wells) are being used in developing Tazovsky deposits.
The wells at the Tazovsky field are similar to offshore wells in terms of their uniqueness and complexity, and are among the most challenging in international practice.
Reserves initially in place are estimated at 419 million tonnes of oil and 225 bcm of gas.
Production infrastructure at the field includes:
- oil & gas wells
- a gas turbine power plant
- oil & gas treatment facilities
- oil & gas pipelines
- a crude oil delivery and acceptance point (CODAP)
- an employee housing complex
The launch ceremony for the Tazovskoye field took place on 16 June 2021.
Using a modular-block approach has reduced capital-construction volumes and halved lead-times in building field infrastructure.
