| Probabilistic oil and gas resource assessment for subsurface areas taking into account the dependence of geological risks of aggregated local objects by area and section | |
| The article discusses the methods for obtaining a probabilistic estimate of oil and gas resources for subsurface areas based on summing up probabilistic estimation of local objects (traps) resources, taking into account the dependence of their geological risks. The formalization of the dependence of geological risks of traps was carried out by separating and probabilistic description of the geological factors, leading to the formation of oil and gas deposits, into common areas for all traps and local ones that operate within individual local objects. Two methods are proposed and analyzed: analytical method and Monte Carlo method. The identity of the results of both methods is confirmed by the given conditional example. The statistical interpretation of the probabilistic assessment of the site resources is given which allowed us to introduce the concept of “geological risk” for the site and thus to determine two types of resource estimates – taking into account the geological risk, and excluding geological risk. The geological conditions for the practical application of the proposed methods are defined. Keywords: probabilistic oil and gas resource estimates; dependence of geological risks of local objects; summation of probabilistic estimates of resources of local objects, taking into account their geological risks. |

| Method of probabilistic oil and gas resource assessment for the subsurface areas at the exploration appraisal phase | |
| The article offers an analytic method for obtaining a probabilistic of oil and gas resource estimation for subsurface area presented by a hierarchy of geological objects of different scales (subsurface area, layer, trap). The conditions for structuring objects of different scales define for this objects availability of both independent and dependent geological risks. It is assumed that dependency of geological risks in the hierarchical scheme is inherent in objects of a smaller scale (single layer traps) due to the presence of regional geological features common to larger scale objects (layer). The method is based on the sequential procedure of analytical summation probabilistic resource estimates of objects from a smaller scale (trap) to larger scales (layer and subsurface area) when correcting a dependency of geological risks of traps in each layer. This method allows us to reduce the overall problem of summing to the problem of summing probabilistic resource estimates with independent geological risks Keywords: probabilistic oil and gas resource estimate; multi-scale objects; independent and dependent geological risks; summation of the probabilistic resource estimates; accounting of the geological risks. |

| Summation of probabilistic net present value estimates of local objects taking into account of a geological risk | |
| The article considers the methods of summation probabilistic net present value (NPV) estimates of local oil and gas objects (prepared for drilling traps) with account of the geological risk associated with these objects: Monte-Carlo method and the analytical method, proposed by authors. The problem is solved for the following conditions: a) various probabilistic NPV estimates of the traps; b) various risk capital of the traps; c) various probabilistic characteristics of trap's geological risk. It is shown that the probabilistic total NPV estimates, obtained by applying the methods under consideration, coincide. The specific characteristics of these estimates are analyzed, and conditions of their practical application are defined. Keywords: local objects (prepared for drilling traps, probabilistic net present value (NPV) estimates; summation of the trap probabilistic net present value (NPV) estimates; geological risk accounting. |

| Geological-economical evaluation and analysis of plays risks | |
| Currently the expression "play" is widely used both in foreign and domestic practice of geological exploration for oil and gas. In the hierarchy of objects of geological research, the playground occupies an intermediate position between local and regional objects, which determines its dual nature: on the one hand, it is a group of local objects characterized by geological and statistical homogeneity, which makes it possible to evaluate their geological and economic indicators by probabilistic statistical methods, on the other hand, it is an independent object of study and assessment in the process of geological exploration.
The main provisions of the logically ordered methodology for assessing the plays under conditions of uncertainty and risk are based on the English publications.
The concept of "geological risk" has been introduced with reference to a play. Probabilistic estimates of geological and economic indicators are received without taking into account the geological risk - under the condition of the productivity of the play, and taking into account geological risk - assuming possible non-productivity of the play.
Keywords: geological prospecting for oil and gas, geological hazard, accounting methodology for uncertainty and geological risk. |
