This article demonstrates using geostatistical modeling controlled by seismic data as one of the best way to predict reliable reservoir properties distribution under the conditions of its significant lateral variations wherein the thickness is quite small. Also it shows the realizations ranking and the initial geological model updating by separating one more prospecting layer. What is more the risk assessment has been done for different uncertainty origin. Copyright © 2014 by the European Association of Geoscientists & Engineers. All rights reserved.

A method of formal description of a production profile and a method of sensitivity analysis of economic performance factors and technological parameters to the shape of the profile are developed. The shape of the profile is described by a simple analytical function depending on three parameters characterizing production growth and decline, peak production. This analytical description provides an ability to systematically change the shape of the profile and thus an ability to calculate economic parameters such as the net present value or technological parameters for shape changed profiles. The calculated set of economic and technological parameters paves a way to simplified computations of these parameters for production profiles of more or less arbitrary shapes which were not included in the initial set of profiles. Alternatively the methods presented in the paper allow one to choose the shape of the production profile which would generate given economic performance. The methods could be used to improve quality of business planning and to reduce its cost.

An unified methodology of the planning and execution of hydraulic fracturing on the basis of new approaches to the setting of geomechanical properties of rocks with the help of correlation dependencies between the readings of methods of a standard set of well survey and laboratory core analysis data is developed and tested. The comparison of results of hydraulic fracturing simulation, based on standard approaches, with the proposed method data is carried out. The consistency and validity of the method of correlation functions, as well as the possibility of its use by contractors for the simulation of hydraulic fracturing are shown. Testing of the method was carried out by results of 60 operations of hydraulic fracturing.
