SeverEnergia, a Russian joint venture of Eni SPA, Novatek, Gazpromneft, and Enel, has started production of natural gas and condensate from Samburskoye field in the Yamal-Nenets autonomous district of western Siberia, Eni reported (OGJ Online, May 21, 2009).
The initial production rate is 43,000 boe/d. Output is to peak in 2015 at 145,000 boe/d.
The joint venture is developing the field with two integrated production systems incorporating three trains for gas and condensate and two trains for rim oil. Facilities are in the Purov district of Tyumen about 150 km northeast of Novy Urengoy.
Gas and condensate development involves 98 production wells, including 68 new horizontal wells, 15 slanted wells, 11 workovers of existing wells, and 4 sidetracks. Most drilling of the wells, to be located in 12 clusters, is to be finished by 2017.
Facilities include a treatment plant with 18.75 million standard cu m/day of total capacity, a 48-km, 40-in. gas export pipeline, and a 22-km, 12-in. condensate export line.
Oil development will include 55 new horizontal producing wells, 3 workovers, and 35 water-injection wells, 25 new and 10 converted from oil wells. Most of the oil wells are to be drilled and completed by 2018.
Oil treatment capacity will total 1.3 million tonnes/year, 200,000 tpy in a first train and 1 million tpy in a second. There will be a 110-km export oil pipeline.
