It is found that mechanoactivation of natural gas hydrates at presence of zeolite lead to formation of normal hydrocarbons with elongated hydrocarbon chain C13-14. Presumably oligomerization of hydrate hydrocarbons during mechanoactivation takes place through zeolite dealumination - the process proceeding at high temperature and availability of water steam.
Keywords: mechanoactivation, natural gas hydrates, clinoptilolite, heulandite

http://www.ogbus.ru/eng/authors/Pillai/Pillai_1.pdf
This paper focuses on the strategic opportunities available in the upstream oil and gas sector. It analyses the current market structure in the Middle East and examines options for companies active in the mid-stream and down-stream sectors within the region to develop new business in the upstream sector.
This paper is essentially a corporate case study. The methodology adopted combines a literature review with sampling and information gathering approaches to a relatively small number of key industry players and opinion formers.
There are some specific low risk opportunities for medium sized engineering, procurement and construction (EPC) companies in upstream off shore area with some common options for organic growth and acquisition. Key acquisitions may form part of an overall growth strategy and companies pursuing this route need to prepare accordingly, especially for post acquisition integration.
This case study article draws upon qualitative primary data from a relatively small number of key people. It will have influenced the conclusion of this research. A broader study is recommended, however, this research has been conducted in areas that are highly sensitive for companies and in which relatively small numbers of key decision makers hold major influence.

THE LATEST IN OIL FIELDS DEVELOPMENT PROCESS MANAGEMENT OR THE ISSUE OF OIL PRODUCTION STABILIZATION DISCRETE SYSTEM DESIGNING ON THE BASIS OF TIME ROWS
http://www.ogbus.ru/authors/Agaev/Agaev_3.pdf (in Russian)
Methodological and practical questions of time rows analysis conformably to dynamic system development of oil field are stated in the article.
It is supposed that development of given system takes place under external influence, i.e. water is injected into oil - bearing bed for pressure maintenance in them. And greater theoretical and practical value gain problems of technological factors predicting, determination of inertial system transfer function and designing of controlling scheme with feed forward and feedback. All these problems are studied with use of the same apparatus (device) for time rows analysis that was noticeably getting developed recently. Such development is quite logical in the context of modern information and measuring and computer technologies improvement that is integral part of modern technological processes system control.
So far as problems of predicting and control are closely connected with each other and their specific peculiarities can simultaneously taken into consideration at development of transfer functions models, and these formers are integral part of the whole designed system of oil production stabilization, different aspects of considered development object transfer function modeling are thoroughly enough investigated in the article. Model structure is determined on concrete example retrospective analysis of oil, water production main time rows factor change and, as well, according to injected into reservoir water rate and by non-linear method of the least squares its adjustment to real data is carried out. Because of water injected rate transfer function model input variable while output variable oil-field total (overall) production and certain mechanism of non - controlled disturbances acting inside dynamic system wittingly was included into model structure, solution of the problem of these disturbances influence upon output factor change becomes obvious. The last circumstance takes central place in designing of optimum stabilization different systems. It is clear that such system minimizing standard deviation of development drive output (oil production) from given value can calculate and realize (automatically or manually) optimum controlled attacks of reservoir water injection.
The article is constructed on the basis of rich algorithmic, software and information support that makes it more flexible and efficient at changing conditions of introduction and automation of scientific researches. Developed complex can be easily adjusted to the case of separate development well.
Keywords: time rows, oil field, oil and water production, water injection, stochastic model, transfer function, autoregression, autocorrelation, mutual correlation, standard error, dispersion, feedback, evaluation of model parameters, control, controller, method of the least squares, iteration, residual error criterion, predicting, time delay, compensation of disturbance, identification

The expedience of obtaining data about multiphase flow regime of the production well and separate phases flow rate has been substantiated. The combination of hydrostatical and cross-correlation methods for in-line flow phase composition determinations has been proposed. Production well flow regime identification is realized by artificial neural network processing of acoustical and differential pressure pulsation signals symbolization.
The data about differential pressure in a flow profiles in two points (on the fixed spacing interval one from other) in pipeline has been used for liquid hold-up measurement. Àn improved impedance method is used for watercut determination. The hell of the betterment is made up of the special structure flowcell development. The flowcell design is provided increased device sensibility in consequence of in-line separation towards high gas void fraction multiphase flows.
Separate phases flow velocities has been determined in consequence of acoustical signals wavelet and cross-correlation processing. It has been realized by means of the designed data processing algorithms for discrete wavelet transformation and decomposition of informative signal by digital signal processors.
The offered method has been investigated and tested on the designed laboratory multiphase flows simulation facility and field test facility. Device design has been developed for an on-line production well control and extraction hydrocarbon wells optimization in the field environment.

GEOLOGY-ENGINEERING CLASSIFICATION OF SHALE FOR DRILLING PURPOSE AND HYDRATE DRILLING FLUIDS
http://www.ogbus.ru/authors/Inosaridze/Inosaridze_1.pdf (in Russian)
Practice of drilling wells shows that using modern drilling tools and the equipments not allows drilling high quality wells in the shale formations. In our opinion, it is related by that at a choice and application of drilling fluids are not considered distinctions in property of shale, and properties of drilling fluids choose without features of interaction of components of drilling fluids among themselves and shales.
The existing level of development of a science and technologies shows that the new approaches on management of properties of various objects are nanotechnology. The considerable part of researches in this area originates in object supramolecular chemistry and borrows its approaches.
Self-organization molecules and they clathrates in new structures are object supramolecular chemistry.
Use of theories supramolecular chemistry with reference to shale and drilling fluids allows to development new ways of management of their properties.
Will allow choosing optimum technical decisions at a stage project and buildings of objects of an oil and gas production complex
Results and conclusions:
1. Existing theory about a shale structure, processes of its hydration, differ considerable contradictions. Using of representations supramolecular chemistry for the shale description as hydrate inclusion compounds (clathrates), allows to specify its structure, the processes proceeding at its contact to water, a condition and properties depending on thermodynamic shale living conditions;
2. Efficiency of action of drilling fluids on shale increase with formation hydrate inclusion compounds (clathrates); they block internal structure of water in shale and fasten its particles;
3. Use of ions and hydrocarbonic connections is preferable to formation hydrate inclusion compounds (clathrates) in shale with effective size ~5*10-10 m, they are capable to form hydrate structures: Cubical-I, Cubical-II;
4. Establish the pattern of formation hydrates inclusion compounds (clathrates) during of hydration of shale depending on properties of shale allows optimizing composition of drilling fluids.
5. Representations supramolecular chemistry allows to optimize known and to find new ways of management behaviors of shale and to classify them for drilling purpose.
