Hydraulic Fracturing Operation by Samotlorneftegas gets high evaluation at Specialized Rosneft Conference

October 31, 2016/ 10:46

Nizhnevartovsk. Hydraulic fracturing operation conducted by JSC «Samotlorneftegas» was highly estimated at the second specialized conference organized by OJSC «NK «Rosneft» - «Petroleum Exploration and Production Technologies 2016». The Subsidiary’s achievements were awarded a diploma for the best technological solution in the field of hydraulic fracturing in 2016.

It is worth reminding that at the end of last year a unique operation of 20-stage fracturing was performed at the Samotlor oilfield. Before that, the record number of frac stages in the national oil industry was 16.

The Samotlor pilot well was drilled within 23 days, its horizontal section length equaling 510 meters and the distance between frac ports being 24 meters.

The production rate of the drilled well amounted to about 100 tons of oil per day.

Samotlorneftergas has been actively searching for new technological solutions in the field of multi-stage fracturing since 2009, according to press – office of the company.

Analysis of the best international case – studies enabled the Subsidiary’s experts to adjust the existing technology to the present Samotlor oilfield conditions.

Starting from 2012, Samotlorneftergas has been successfully applying selective packers and burst port collars for multistage fracturing operations at new well stock.

Drilling high-tech wells is an optimal way of edge zones’ development at the Samoltor oilfield, which earlier had been considered to be non-economic.

Multistage fracturing technology allows effective development of the unconventional reserves or hard-to-recover reserves.
