Gazprom Neft subsidiary Gazpromneft-Yamal has succeeded in drilling a 2,000-metre horizontal-section
OREANDA-NEWS. Gazprom Neft subsidiary Gazpromneft-Yamal has succeeded in drilling a 2,000-metre horizontal-section well at its Novoportovskoye field — the group’s longest to date. Construction of the well was completed in a little less than 25 days — 18-percent ahead of schedule, at a rate of 1,000 metres every 5.39 days. The total length of the well is 4,630 metres, at the target stratum depth of 1,830 metres below sea level, with drivage efficiency (penetration of productive strata) exceeding 94 percent.
Geological information obtained during the drilling process will allow the geological structure of the Novoportovskoye field to be more accurately defined, allowing the most effective approaches to be used in its development. Construction of development wells is being undertaken in the course of pilot testing included in the Novy Port technological project development plan.
