NINE TIMES MORE
Rospan International (Rosneft subsidiary) carried out a record hydrofracturing at the Urengoiskoe field, which resulted in the 9 times increase of production rate.
There had been pumped 400 tons of proppant to benches of Achimov formation, which proved the efficiency of a record hydrofracturing at the 2-06-03 well. The previous record was 312 tons.
Following the results of the well performance, gas flow rate increased from 70 to 600 thousand cubic meters daily, and condensate increased from 12 to 200 tons daily. Meanwhile, bottom hole pressure is close to dew point pressure, which provides optimal conditions for the deposit exploitation. New approach to hydrofracturing allowed to increase the efficiency of operated activities by 50%.
Obtained results are directly consequential on systematic work carried out by enterprise geologists aimed at optimization of hydrofracturing technology, and give assurance in high recovering rates stipulated in the Rospan investment project of full field development.
Notes for Editors
Rospan International was the first enterprise to develop Achimov gas-condensate accumulations. It has been recovering gas and condensate at the Vostochno-Urengoisky and Novo-Urengoisky license blocks (the Yamalo-Nenets Autonomous District) since 1996.
Ultimate reserves of hydrocarbons at these license blocks total about 1 trillion cubic meters of natural gas, 150 million tons of gas condensate, and 46 million tons of oil.
Rosneft is intended to increase Rospan gas recovery up to 5.6 billion cubic meters in 2016, and to 18.4 billion cubic meters in 2018, which is stipulated in the integrated project of full-scale development of the Novo-Urengoisky and Vostochno-Urengoisky license blocks.
Within the scope of the project it is expected to drill and equip 275 exploitation gas-condensate and 19 oil wells, construct complex gas treatment plants, a condensate stabilization unit, an oil treatment unit, a railway liquid bulk terminal, and significant amount of pipelines of different application.

AN - China National Offshore Oil Corp. (CNOOC) is willing to invest $3 billion in its existing oil and gas operation in Nigeria, the Nigerian National Petroleum Corporation (NNPC) said on Sunday following a meeting with the Chinese in Abuja.
REUTERS - Production at Libya’s giant Sharara oil field was expected to fall by at least 160,000 barrels per day (bpd) on Saturday after two staff were abducted in an attack by an unknown group, the National Oil Corporation (NOC) said.
IMF - Output grew by 3.8 percent in 2017, underpinned by a resilient non-hydrocarbon sector, with robust implementation of GCC-funded projects as well as strong activity in the financial, hospitality, and education sectors. The banking system remains stable with large capital buffers. Growth is projected to decelerate over the medium term.
IMF - Higher oil prices and short-term portfolio inflows have provided relief from external and fiscal pressures but the recovery remains challenging. Inflation declined to its lowest level in more than two years. Real GDP expanded by 2 percent in the first quarter of 2018 compared to the first quarter of last year. However, activity in the non-oil non-agricultural sector remains weak as lower purchasing power weighs on consumer demand and as credit risk continues to limit bank lending.
