In 2018, pilot works were carried out at Boca de Jaruco field to implement methods for enhancing reservoir recovery.

As a result of exploratory drilling in 2018, the increase in hydrocarbon reserves, taking into account Zarubezhneft JSC share totaled to:

  • 1,011.8 thousand tons of oil equivalent at JV “Vietsovpetro”, based on the results of drilling the appraisal wells VN-1803, VN-49, VN-1903, MTD-2X (South-West section) and exploration wells VN-56 and VN-20V at White Tiger field;
  • 83.64 thousand tons of oil equivalent in LLC “JC “RUSVIETPETRO” based on the results of drilling 2 holes of 5R exploration well and testing in lateral well No. 5_1, examination of the core from the previously drilled well No. 14R at South-Syurkharatinskoye field;
  • 470 thousand tons of oil equivalent in Orenburgnefteotdacha JSC according to the results of drilling and testing an exploration well No. 3P at Pashkinskoye field.

Based on exploration and production wells drilling data for a period 2012-2017 of JV “Vietsovpetro” fields (White Tiger, Dragon, White Hare, Southern Dragon-Sea Turtle) a planned reassessment of hydrocarbon reserves was performed. According to the reassessment results, hydrocarbon reserves increment in category 2Р amounted to 17 499 thousand tons of oil equivalent in total. In general, taking into account the reassessment carried out for East-Yanemdeyskoye and Sikhoreyskoye fields of LLC “JC “RUSVIETPETRO” and Kharyaga PSA, the reserves increment amounted to 12,783 million tons of oil equivalent in the reporting year.
