EVENTS Oil prices Duty abolition Increase in production capacity The new head of “Rosneft” Nord Stream Presidential elections Gas wars Launch of new production Stock market crash The productivity of the Bazhenov formation will be considered in KhMAD RussNeft launched a pilot project for the construction of wells at Sredne-Shapshinskoye oilfield, which the company will explore the Bazhenov shale. In 2017, the company intends to drill on the field 16 new wells in 3 well clusters. The productivity of sediments is directly related to abnormally high formation pressure (AHRP), which is caused by the lack of primary migration of hydrocarbons in traditional reservoirs. The presence of abnormally high pressure zones improves the properties of the reservoir, this increase the time of natural exploitation without the use of secondary methods. But, at the same time increases the threat of complications during the drilling. For prediction of pore pressure prediction using various types of well logging, seismic, drilling data. Given the presence of a zone of abnormally high pressure that is unique to the Bazhenov deposits, drilling in the Medium-Shapshinskoye oilfield use innovative service prediction of pore pressure prediction. The new service is based on an integrated approach: the hardware is built on the basis of engineering calculations that helps to minimize risks during the drilling. Resources of the Bazhenov formation in Sredne-Shapshinsky field contain more than 40 million tons. Oil from coral reefs In the framework of the implementation of the Technology strategy Gazprom Neft has developed a program of introduction of new technologies for extraction of oil from carbonate and fractured reservoirs. These include more than 40% of recoverable reserves (about 600 million tons of hydrocarbons). At the fields of Gazprom Neft about 40% of the remaining reserves are contained in carbonate reservoirs. The largest assets with such deposits are the Eastern section of the Orenburg oil and gas condensate field, and Chonskoy at Kuyumbinskoe field in East Siberia, the project of Badra in Iraq, the Prirazlomnaye field in the Pechora sea. A new program developed by the Scientific and technical center of Gazprom Neft and includes 12 technological projects in the field of exploration, mining, drilling and production of oil. In particular, Chonskoy project will apply technology for intensification of oil production from a carbonate reservoir, the pores of which are partially filled with salt and do not leak oil. On at Kuyumbinskoe field is the choice of technology to acid fracturing and on the Eastern section of the Orenburg field of technological solutions aimed at the search of optimum modes of operation of the wells. Reactivate plugged and abandoned wells RN-Sakhalinmorneftegaz has successfully completed the construction of the energy complex Katangli on the same field and started commissioning works. As reported on March 1, 2017 by Rosneft, modular and energy complex became the 1st of the largest in the Sakhalin region. The total capacity of 12 MW 6 gas turbine units provide, capable of operating in PNG. In addition, 5 of the boiler can produce 125 t/h process steam. In all, the complex of over 20 buildings and structures: transformer station 6/35 kV, the area of power generation, automatic gas distribution station, boiler, etc. With the launch of the energy complex of the Katangli field is expected to resume production at the mothballed wells that will provide growth in daily production by more than 30%. 12 ~ Neftegaz.RU [3]
NGL: to be or not to be Reached his hands up in the Arctic The second wave of crisis EVENTS Nord Stream built Gas prices Russia has joined the WTO Boguchany HPP launched Stock market crash Multi-stage fracturing from LUKOIL LUKOIL-Western Siberia provided pilot works on the introduction of new technologies to conduct multi-stage fracturing. The company tested the upgraded layout completion wells for multistage fracturing operations on fields in KhMAD. Due to this, the company was able to achieve a higher production rate compared to traditional methods. In the layout, in addition to the suspension of the shank and tooling for hydraulic fracturing, packers include swellable hybrid elastomers. Pilot work was conducted in 5 wells Imilorskoe and Tevlinsko- Russkinskoye fields. The use of hybrid elastomers provide absolute isolation of zones of fracturing and significantly reduce the time costs during the descent layout, but also eliminates technological risks, since the elastomer is able to swell in any borehole fluid. Multi-stage fracturing from Gazprom Neft At the Novoportovskoye field Gazprom Neft-Yamal successfully conducted a 20-stage fracture on “nonspherical” technology. This method was first applied in the development of hydrocarbon deposits on the Yamal peninsula based on the use of reusable sliding joints, allowing you to open and close individual ports of hydraulic fracturing. This design allows in the course of further operation of the well to cut off or separate fractures to prevent water inflow and gas, or all at the same time – to refracturing. The use of special sliding sleeves allows you to optimize hydraulic fracturing, isolating non-design, water-cut or gas-saturated intervals. Packer installation falls below the first sliding sleeve. The protrusions of the locator moving the installation up on a stem are fixed in the groove located below the sliding sleeve. Under the weight of a column of coiled tubing packer license is activated. Starting 1st daily production from the wells was 188 tons of oil. The launch of the 2nd bore is planned for the near future. In the depth of the Yakut dungeons In the Krasnoyarsk region and Yakutia Rosgeologiya will conduct an update of locations of appraisal wells, the construction of which will allow a research of oil and gas fields. It is expected to lay well: Tenaska 215, Srednevilyuisky 283, Vilyuchinskaya 1, Wabuska 365, Dulisminsky 1. They will allow a research of Katanga, South Tunguska, Severo-Tunguska, Vilyui and Suggerisco oil and gas fields. The result of the implementation of the project will be the adjustment of the locations of shallow wells based on the geological model and development of recommendations for further geological exploration (GE) in the territory. The finishing of the works is planned in the end of 2018. [3] Neftegaz.RU ~ 13
