... event investigation, as a rule, is to prevent a recurrence of such a safety event in the future by correcting deficiencies in the HSE management system. The results of the investigation should identify processes, practices, procedures that should be corrected or improved, and determine which processes...

... starting pressure is relevant. Uncertainty of this design value depends on initial parameters, specified by ranges of values. Use of an analogy between computing experiments and indirect measurements in theoretical metrology has permitted to apply a standard procedure on expressing the uncertainty...

... extremely rarely turns into one. In the paper the new approach to casing eccentricity calculation is suggested. It considers the possible sagging of the casing between two adjacent collars. First, the deflection between two nearest centralizers is determined. The calculating procedure of casing deflection...

...I. N. Abdulin; V. A. Baikov The PDF file of this paper is in Russian. Coarsening of computational spatial grids is one of the main ways to reduce the cost of computing resources in geological and hydrodynamic modeling of hydrocarbon reservoirs. The procedure of overriding reservoir properties...

... structure and rock-fluid interactions. The differences also influence on the study of the carbonate cores, especially on core handling and preparation procedures prior to laboratory tests. The main distinguishing features are following: high heterogeneity (anisotropy) of properties; presence of special...

... pay of Bobrikovskian horizon saturated with high-viscous oil we illustrate the efficiency in applying the enhanced fluid recovery methods. It is scientifically proved that the procedure of fluid forced recovery (FFR) is one of the most effective and efficient methods in stimulating oil recovery...

... in these pipeline networks as well as to designing new universal service maintenance procedures for the integrity rehabilitation at pipeline transportation facilities. Transportation facility may use simultaneously the pipelines manufactured from various materials, like metals, fiber-glass plastic, polyethylene...

... of procedures for selecting operation parameters of wells ejection system consisting of mixed connection of jet pumps. Application range of this system is discussed. We investigated the characteristics of hydraulic connection between elements of ejection system. It is found that operation mode of bottomhole...

... survey to evaluate displacement efficiency and relative permeability in-situ. Test procedure includes several "injection-production" cycles with brines of different salinity. Dynamic well data are supplemented by periodical water saturation measurements by pulse neutron logging methods and analyses...
