The Company continues its drive for expansion and improvement of its in-house services to deliver high quality of services and gain a competitive edge.
In 2019, the Company’s drilling service completed 5,753 thousand m of drilling on-site (1,628 wells, including 27 exploration wells). The share of horizontal drilling reached 62% (up 14% from 2018).
The operating fleet of the Company’s drilling service in 2019 stood at 267 drilling rigs with an average age of 11 years. The Company has 237 drilling crews.
- Rosneft successfully progressed with its programme to scale up the technology for drilling two-string horizontal wells with oil based mud.
- A drilling crew of the Khanty-Mansi branch of RN-Bureniye set a record when drilling horizontal well No. 2406 from well pad No. 24 at the Kondinskoye field. The well was drilled in 17.5 days at a commercial drilling speed of 6,893 m per rig per month.
- A drilling crew of the Nefteyugansk branch of RN-Bureniye broke the industry record for the fastest construction of a two-string horizontal well. The drilling at the Salymskoye field took as little as 7.4 days, 20% faster than ever before. The commercial drilling speed exceeded 14 thousand m per rig per month.
Today, RN-Service is the largest company for well workover and servicing, with branches in 13 Russian regions. In 2019, it provided well servicing to 21 Rosneft’s upstream companies, covering 43% of Rosneft’s needs for well workover and servicing.
Well workover and servicing works performed by RN-Service in 2019 totalled 38,330, exceeding the business plan target by 1,191 (103%). Actual orders processed per workover and servicing crew amounted to 57.4 per year (106.5% against the business plan target). Average service time reduced by 7.8% against the target.
In 2019, the Company received and put into operation four new hydraulic fracturing fleets.
RN-GRP completed 4,905 hydraulic fracturing operations at Rosneft’s fields, exceeding the business plan target by 312 operations (107%).
RN-Service transferred 610 vehicles to RN-Transport as part of the establishment of a service holding company based on RN-Transport that will provide transportation services to Rosneft’s companies.
579 inefficient or unused machines were withdrawn from operation.
Key Achievements in 2019
In January 2019, we launched an in-house well logging service at Bashneft-PetroTest and started well logging and blasting and perforating operations at Bashneft-Dobycha’s fields. This project will help boost the efficiency of the Company’s exploration and development activities, reduce the cost of well logging, optimise the amount of log data, and enable import substitution in this area.
In 2019, as part of the Rosneft–Rosatom R&D cooperation, SMIS-172-B multi-parameter logging while drilling tool was tested on five wells of the Severo-Khokhryakovskoye field (Varyeganneftegaz). The system is based on a technology-intensive and environment-friendly induced gamma-ray spectroscopy module, first of its kind ever manufactured in Russia. The tests produced important data based on which the system will be finalised for future commercialisation. Following the tests completed in wells of Samaraneftegaz and RN-Krasnodarneftegaz in 2016–2017 as part of the Company’s cooperation with Rosatom, the Technology Expert Council of the State Commission for Mineral Reserves issued a positive opinion on possibility of using log interpretation data obtained from this logging tool to substantiate the estimates of hydrocarbon reserves.
To improve the production planning accuracy and select the most appropriate hydrocarbon extraction technologies, Rosneft makes extensive use of field models created by its proprietary RN-KIM hydrodynamic simulator. This advanced software has been widely exploited by the Company for over three years and is adapted to the geological and operating conditions of the fields the Company is developing.
In 2019, the use of RN-KIM increased to 77%. We released a new version that allows us to quickly (using graphics processing units or computer clusters) perform modelling calculations for oil and gas condensate fields that require computation-intensive analysis.
In 2019, as part of the efforts to expand its capabilities in solving the most pressing operational issues related to log interpretation, the Company created a development concept and a prototype for RN-PetroLog, proprietary petrophysical modelling software that supports integration with corporate databases, multi-well data processing, and computerised data interpretation.
