Research into the innovative potential of an oil and gas company at different stages of field development

Article preview

The paper presents an overview of research into the methods and principles used to assess the innovative potential of an oil and gas company. The validation is provided for the conceptual framework of the innovative potential, which is characterized by a combination of resources having a specific value for the oil and gas sector. The paper gives a detailed overview of the resources, which determine the innovative potential of the oil and gas company. A system of indicators for assessing the innovative potential of the oil and gas company, including six indicator groups, has been proposed. Key distinctive features of the oil and gas company technological development have been determined based on the use of potential for innovation at different stages of the field development. Technical and economic indicators of the oil field development at different stages are described. A concept of Intelligent Field technology is outlined, representing an innovative system, implementation of which determines a level to which the potential for innovation of the oil and gas company is tapped.

The phenomenon of isothermal transition of metastable aluminate solutions into the labile area and prospects of its industrial use

Article preview

The paper presents theoretically based requirements for the activation of synthetic gibbsite for maximum solubility of the activated product. The article describes the methodological foundations of gibbsite thermal activation and its effectiveness evaluation in terms of aluminate solutions decomposition. It is shown that to obtain high-saturation aluminate solutions, activation should provide generation of the reagent with highly-developed surface area, which is not identical to the structure of the deposited gibbsite. As a result of high-gradient thermal activation of synthetic gibbsite, it has been found that the targeted product develops predominantly an amorphous structure with a specific surface area up to 256 m2/ g, preserving its primary particle size. Activation products were investigated using modern methods of physical and chemical analysis. The experimental results confirmed the possibility of the activated product dissolution in the aluminate solution with a metastable compound and their spontaneous decomposition with aluminum hydroxide formation, characterized by high dispersion ability. It is shown, that a significant difference in kinetics and decomposition rates of solutions is connected with the use of a seed material with different particle size composition, which leads to the development of competing mechanisms, resulting in seed recrystallization, homogeneous and heterogeneous nucleation.

Application of air-permeability method for filterability prediction of different materials

Article preview

The article is devoted to research work, in which an attempt was made to apply the Blaine-meter for direct assessment of filterability of different materials. In the theoretical part of the article the main laws linking the Blaine index of the powder material and the average specific cake resistance are described. A number of experiments with materials taken from actual operating plants were carried out. To determine the Blaine-index the laboratory Blaine-meter was used, and to determine the average specific cake resistance standard tests of filterability on the batch pressure filter were carried out. As a result of processing experimental data and the necessary calculations direct relations between the Blaine-index and average specific cake resistance were obtained.
