EXPANDED SESSION OF THE SCIENTIFIC AND TECHNICAL COUNCIL ON TOPIC “ISSUES AND PROBLEMS OF DEEP AND SUPER-DEEP DRILLING”EXPANDED SESSION OF THE SCIENTIFIC AND TECHNICAL COUNCIL ON TOPIC “ISSUES AND PROBLEMS OF DEEP AND SUPER-DEEP DRILLING”EXPANDED SESSION OF THE SCIENTIFIC AND TECHNICAL COUNCIL ON TOPIC “ISSUES AND PROBLEMS OF DEEP AND SUPER-DEEP DRILLING” HELD IN THE FRAMEWORK OF THE 2nd INTERNATIONAL FORUM: KAZAKHSTAN GEOLOGY FORUM: OIL &GAS 2018
May 18, 2018, under the chairmanship of Uzakbai KARABALIN, deputy chairman of the KAZENERGY Association, an expanded meeting of the Scientific and Technical Council on “Issues and problems of deep and super deep drilling” was held. Representatives of the companies KMG-Eurasia LLP, KaraTau Consulting LLP, NAO AUNG, NCOC NV, Gazprom VNIIGAZ, Ufa State Oil Technical University, GTI Company (Russia) and Schlumberger took part in the event.
During the meeting, issues related to the specifics of deep and super deep drilling were considered. The experts presented new developments, achievements, and proposals on this topic.
Thus, A. Denyakin, General Director of KMG-Eurasia LLP, in his report “Super-deep drilling as a recognized need for an international project “Eurasia” noted that according to the International Energy Agency (IEA), by 2030 the annual oil consumption will increase by more than 1/3. In this regard, the significant resource potential of the Caspian region will be particularly in demand. First, we are talking about the Caspian Sea natural gas (up to 40-60 billion tons of fuel equivalent), where there is a possibility of discovering large hydrocarbon deposits (which have not yet been studied at great depths). The project is expected to be implemented through the creation of a Consortium of international oil and gas companies and service companies.
A.Dalbaev, executive director of KaraTau Consulting LLP, presented information on the Eurasia project, continuing the issue of the challenges of the super-deep Caspian-1 well. He noted that at present more and more technologies are being used that were previously used in other sectors, such as space, seismology, underwater work and photography. The use of new materials significantly increases the stability and capabilities of casing strings, wellhead equipment, geophysical instruments, drilling fluids, bits and other downhole tools that can withstand extreme conditions arising from the drilling of ultra-deep wells up to 15,000 m.
Interesting were the conclusions of the report of the senior lecturer of the department “Geology and geophysics” of NAO AUNG Aysulu Tourniyazova, who presented “Forecast of petrophysical characteristics of sedimentary rocks at depths not yet reached by the boreholes”.
Within the framework of the meeting, Yuri Bokov, the drilling supervisor of the Kashagan field and Ivan Gas, the manager of production operations support (geology), North Caspian Operating Company NV (NCOC NV), told about innovative technologies for drilling of narrow profile and over-profile wells. The use of automated drilling tools (ADT) allows to provide high-quality execution of a wellbore and to improve the process of control of its trajectory.
Mitalim Gaidarov, Head of the Advanced Research Laboratory of Gazprom VNIIGAZ, presented the results of the analysis of the application of polycationic drilling fluids to the present on the example of the construction of wells of the Astrakhan gas condensate field.
Farid Agzamov, a professor at the Ufa State Oil Technical University, in his report focused on the problems of securing superdeep wells. Anton Ocheretany, Senior Geochemistry Engineer, GTI (Russia), also delivered a presentation “About the project “Solution of geomechanical, petrophysical and geonavigational modeling for optimization of deep hole drilling”. Moreover, the expert on the development of Schlumberger fields, Mikhail Charupa, told the audience about the new capabilities of testers on the cable and their application in exploratory wells, including the operational estimation of reserves.
