Geological modeling based on 3d facies variation in case of AV reservoirs of Samotlorskoye field

Key words: 3D geological modeling, facies model, artificial neural network, Samotlorskoye field.

The geological model of AV reservoirs of Samotlorskoye field was built. Lithology and reservoir modeling is based on the 3D facies model. To increase accuracy of the facies modeling an artificial neural network was applied for facies estimation in uncored wells. The usage of the facies model improved the convergence of the lithological and petrophysical models with the field data and also enhanced the prediction of reservoir properties distribution in the undrilled zones.

Determination of closure pressure for hydraulic fractures using instruments of geomechanical modeling

Key words: low permeability reservoirs, hydraulic fracturing, fracture initiated by injection, strain-stress state, fracture closure pressure.

The paper presents a method for calculation of closure pressure on hydraulic fractures on injection wells as a parameter determining the beginning of fracture growth. The method is based on formation stress-strain state modeling in an area close to the fractured wellbore. The model for calculation takes into account the evolution of pressure field caused by exploitation. The results of modelling show good agreement with field data and can be used as a method alternative to field measurements methods, that now-a-days are the basic instrument of closure pressure determination.

Non-Darcy fluid flow modeling in low-permeability reservoirs

Key words:well testing, non-Darcy flow, low-permeability reservoirs.

The paper discusses numerical results on non-Darcy fluid flow modeling in low-permeability reservoirs. We investigate the pressure pattern behavior under a nonlinear relation between flow rate and pressure gradient. The use of non-Darcy flow modeling in pressure/rate transient field data analysis exhibits new possibilities for estimating permeability and drainage area. The results obtained show that the effective drainage area is significantly smaller than interwell distance in a development system cell. This may cause decision making for infill drilling in low-gradient areas.

Experience of using different methods of evaluation of reservoir properties of nanopermeable rocks

Key words: permeability, nanopermeable reservoirs, core samples, GRI method, steady-state permeability.

The subject of the research is the core samples of Late Jurassic nanopermeable deposits of the Bazhenovskaya suite of one of the fields of the Tomsk region (Western Siberia). A comparative analysis of the available laboratory methods for determining the porosity and permeability of the core samples , including the method for estimating the permeability of crumbled core (GRI method), is carried out. The results of studies are applicable at the calculation of hydrocarbon resources in deposits of the Bazhenovskaya suite and evaluation of potential wells flow rates. It is shown that natural fracturing of argillaceous-siliitic deposits of the Bazhenovskaya suite has decisive influence on reservoir properties , increasing the permeability by 2 - 6 orders , and the porosity - by 50 % on average. Noted allows to formulate a strategy of further investigations of petrophysical properties of the Bazhenovskaya suite sediments as characteristic of mainly fissuring void.

Indications of regionally spread gas-bearing horizon of new type at the north of Western Siberia

Key words: gas-bearing horizon, gas blowouts, gas hydrates

Cenomanian gas reservoirs at giant Western Siberia gas fields are at the late stage of development. New gas reserves with gas composition identical to Cenomanian could be found in upper part of Tibeisalin suit located at depth 300-600 m. This suite has good reservoir properties and is regionally spread. It is capped by other regional horizon having trap properties. Drill teams often observe gas liberations from this depth interval when drilling through. Tibeisalin horizon is located in the interval of hydrate stability zone and two-phase gas state is expected. So, new exploration and production technologies will be necessary.

Rationale for selection of consolidated blocks of multilayer and multi-deposit formations for development analysis

Key words: geological blocks, reserve density, inadequate development, priority of reserve development, modeling tasks.

In the Upper Oligocene sediments there is a contradiction between a large number of alternations and deposits and fast production decline during development. There is a need for formation consolidation to create conditions for real development adjustment. This paper presents an approach to form consolidated blocks with different reserve density and different reserve recovery status based on considerations of facies and tectonic features of the field. Reserve quality in different blocks is comparatively assessed and three-dimensional modeling tasks for development system evaluation are set out.

Estimating productivity of horizontal wells with longitudinal hydraulic fractures

Key words: hydraulic fracturing, horizontal wells, longitudinal fractures, productivity.

Efficient frontier for longitudinal fractures is defined, which shifts towards permeability increase with increase of reservoir fluid viscosity. Transverse fractures are more attractive in low-permeability reservoirs. For higher permeabilities, longitudinal fractures are favorable. The lower is the dimensionless conductivity of induced fracture, the more advantageous is to fracture horizontal well longitudinally. If creation of high dimensionless conductivity fracture is unfeasible, longitudinal fractures should be considered. The number of vertical fractured wells equivalent to a single horizontal well with transverse fractures for the conditions encountered in Tatarstan fields is approximately half the number of transverse fractures.

Implicit express simulation modeling of multistage fracturing in horizontal wells

Key words: implicit express modeling; equivalent skin factor; dimensionless pressure loss coefficient on the elliptical mode filtering.

The article describes the technology of implicit express simulation modeling of multistage fracturing in horizontal wells which minimizes the time and resources at the forecast of oil production in models with a large number of horizontal wells with multiple hydraulic fracturing. It also allows making multiple calculations in a short period of time in determining the optimum geometry of reservoir fracture and their quantity per one horizontal well. As a practical example the technology was described for Novoportovskoye oilfield that confirmed the nearness of the results that were obtained with the implicit express simulation modeling and the results that were obtained with explicitly detailed simulation modeling.

Use of natural bitumen as raw materials for receiving bituminous insulating materials

Key words: natural bitumen, oxidation, insulating material, structurally-dynamic properties, structure, physical and mechanical properties.

As raw materials for production of bitumen it is expedient to use tars heavy oil the naphthene aromatic basis with the insignificant maintenance of normal paraffin (mainly to 2 %). Expansion of a source of raw materials of bituminous production due to involvement of the natural bitumen of the Nagornoye field (the Republic of Tatarstan) confirms relevance of researches subject. For increase in productivity of bituminous installations as initial raw materials of receiving insulating materials the high-boiling natural bitumen fractions allocated at an atmospheric and vacuum distillation were used. As raw materials of process of oxidation the fraction, boiling away above 440 °C was used. In natural bitumen of the Nagorny field chemical affinity of components, characteristic for bitumen of high-resinous oil of a Yaregskoye field is revealed. It is established that the increase in quantity of asphaltens in special bitumen leads to premature embrittlement of coverings on its basis.
