ERIELL, an international oilfield services group, presents information on production indicators for the first half of 2021, announces new records on the most complex projects and talks about the large-scale mobilization carried out.
D okunikhin Vitaly Borisovich , First Deputy Chairman of the Management Board of ERIELL Group, General Director of ERIELL NEFTEGAZSERVICE LLC:
“We are pleased with the results of the company for the first half of 2021: we achieved the planned indicators, updated several records, received thanks from customers, successfully implemented 18 mobilizations, 16 of which took place simultaneously.
For 6 months ERIELL constructed 159 wells and drilled 582,951 meters (including 400,000 meters drilled in Russia).
While the main ERIELL projects are still concentrated in Uzbekistan and Russia, we also plan to develop our presence in the Gulf region. The company will continue to work on international projects and will resume drilling in Iraq at the Garraf field in August ”.
In Uzbekistan, the largest and most difficult project is still the Mustakillikning 25 Yilligi project, where, according to the results of 6 months of 2021, a record ROP was achieved when drilling with a 444.5 mm bit, the daily meterage was 362 m.
Within the framework of the Program of Measures to Increase the Production of Hydrocarbon Raw Materials for 2017-2021 for the development of the fields of Uzbekneftegaz JSC, 52 gas pipelines were put into operation, 3 gas collector pipelines were ready for operation, the improvement of 9 wells was completed and 56 wells were connected to electrochemical protection.
In April, a new contract was signed with the Uz-Kor Gas Chemical JV LLC, according to which 25 wells were overhauled in the first half of the year.
Overhaul of 8 wells was performed for JV LLC Natural Gas-Stream, 4 wells were completed, after which a good flow of gas was obtained. For LUKOIL Uzbekistan Operating Company, work was carried out to overhaul 4 out of 11 wells.
In Russia ERIELL continues to work for three main customers: Gazprom, NOVATEK and Gazprom Neft. The largest part of the portfolio is production drilling on complex gas projects in the Arctic, in the area of ??the Yamal and Gydan peninsulas. 90% of the drilling rigs operating in Russia are heavy rigs with a lifting capacity of more than 320 tons, four of which are specially designed to work in the harsh Arctic conditions.
ERIELL continued to work at the Urengoyskoye and Medvezhye oil and gas condensate fields of the Gazprom group, where it built 3 production wells of increased complexity, including the Achimov horizons.
ERIELL built 28 production and exploration wells on gas projects of NOVATEK in the first half of the year.
At the Utrenny oil and gas condensate field (customer Arctic LNG 2, NOVATEK project for natural gas production and liquefied natural gas production):
- for the first time, when cementing the technical casing of well No. 211, one hundred percent quality of contact with the casing and the rock was obtained in the interval of the cement slurry of normal density;
- the quality factor according to the Rosneft method was 1, which became possible thanks to the cement slurry formulations developed by the technological service and specialists of the well cementing shop.
At the Urengoyskoye oil and gas condensate field (customer "Arktikgas") - the longest ERIELL project in Russia:
- a liner with 20 MSHF sleeves was successfully run into the horizontal wellbore of subhorizontal well No. 1500 m long.
- Also on the well, for the first time on the project, MDT work was successfully carried out in the deviated pilot wellbore of the Achimov deposits. The zenith angle in the study interval is 56 degrees.
ERIELL has drilled more than 50 wells for Gazprom Neft at the Vostochno-Messoyakhskoye, Tazovskoye and Novoportovskoye fields.
At the Tazovskoye oil and gas condensate field (customer Meretoyakhaneftegaz):
- horizontal well No. 7107 (2000 m + pilot borehole) was built with an absolute record rate of days / 1000 meters for this type of wells - 3.39 (17.75 days) and penetration rate of 5228 m, of which the length of the horizontal borehole was 2046 m;
- the best result in terms of drilling speed has been achieved since the start of well construction at the Tazovskoye oil and gas condensate field (since 2017);
At the Messoyakhaneftegaz project, ERIELL received gratitude from the customer for a special contribution to the development of partnerships, effective solution of operational and strategic tasks, as well as high adherence to industrial safety requirements.
In addition to operational achievements in drilling in the first half of 2021, ERIELL carried out 18 mobilizations of drilling equipment, 16 of which took place simultaneously.
One of the features of work in the Arctic is the need for complex and lengthy mobilizations in a short time by different types of transport, including along the Northern Sea Route and temporary winter roads. The largest of the mobilizations carried out in 2021 was the transportation of the ZJ-70 DBS drilling rig and equipment weighing 12,000 tons in three months from Novy Urengoy, Abakan and Yekaterinburg through the port of Arkhangelsk to Salman. The total distance was 12 thousand km. This is the third major mobilization successfully organized and carried out by ERIELL in Russia.
Vitaly Borisovich Dokunikhin , First Deputy Chairman of the Management Board of ERIELL Group, General Director of ERIELL NEFTEGAZSERVICE LLC: “It is very pleasant that customers constantly note improvements in our work, efficiency and quality of service. We are constantly looking to work to meet and exceed their expectations . ”
