PetroNeft confirms positive results from Sibkrayevskoye well


DUBLIN -- PetroNeft, an E&P company operating in the Tomsk Oblast, Russian Federation, and 50% owner and operator of Licences 61 and 67, has provided an update on the S-375s delineation well at Sibkrayevskoye oil field.


  • Testing of the S-375s well has been completed, confirming the productivity of the reservoir in this part of the oil field.
  • An ESP was run in the well and achieved a peak rate of 210 bopd on an 8-mm choke and a sustained rate of 150 bopd on a 4-mm choke.
  • The well has been shut in until winter roads can allow oil to be trucked to the Lineynoye processing facilities.

Sibkrayevskoye 375s Well

The cased hole step testing of the S-375s well has been completed. Following this an Electric Submersible Pump (ESP) was installed in the well to determine a stable production rate. The maximum rate on an 8-mm choke was 210 bopd. During the final 5 days of ESP test production the well produced on a 4-mm choke at an average rate of 150 bopd.

Production of the S-375s well has now been suspended as we have filled all storage capacity at site. A total of 1,510 bbl of crude oil was collected. The oil is of high quality with an API gravity of 41o API and is very similar to oil from the S-373 well. Winter Production will commence in December, once winter roads are in place to truck the oil to the Lineynoye processing facilities located about 26 km from Sibkrayevskoye.

The reserve estimate and development plan for the field will be updated with the S-375 and S-375s drilling results in the coming months. This data will help to shape our future plans for Sibkrayevskoye.
