ERIELL Group has drilled the first in Russia commercial development well to Turonian rocks under the project with Severneftegazprom
ERIELL Group has successfully completed drilling of the first well within the framework of the new project with OJSC Severneftegazprom at the Yuzhno-Russkoye oil/gas/condensate field known for some of the most stranded gas reserves. Its peculiarity is abnormally high reservoir pressure, low reservoir temperatures, lithological non-uniformity and variability and low reservoir permeability.
«This development well has for the first time in the RF begun commercial development of Turonian deposits», – ERIELL Group Executive Director V.B. Dokunikhin says.
EREILL Group was elected the main contractor for construction of the horizontal development well with invert end of the 114 degree horizontal wellbore section. True vertical depth being 850 m the overall borehole length made 1804 meters. To maintain the set trajectory parameters ERIELL engaged Schlumberger equipment with an LVD array enabling real-time geosteering and the poroperm properties appraisal. Use of oscillator in the assembly allowed for drilling of the well section with only one relocation of the elements and this with a 50/50 relation of the slant/horizontal hole sections.
Within the framework of this project it is also planned to complete construction of 6 exploratory wells by 31.08.16.
