and mmimums. Authenticity of their selection has been verified 
for clearness of border definition of the separate lineament 
systems and their general modal of values for all research 
territory. The effectiveness of further of research is depended 
on authenticity of selection of the lineaments systems. 
Then the estimation of conformity of the allocated systems of 
lineaments to systems of cracks and breaks of research region 
established by other authors must be carried out. 
The same analysis method uses orientation of linear 
anomalies of the physical fields and geophysical data on the 
studied territory. Two indexes for quantitative description of 
the lineament fields are used: the quantity (density) and 
summary of total length of lineaments. These indexes for unit 
of territory are counted. These two indexes are associated, but 
they do not duplicate and each complements the other. 
For each of the systems are calculated the quantity and total 
length of lineaments. Limits of the extended sliding window are 
used for this calculation. Windows are oriented in accordance 
with azimuths of extended modal (most often met) lineaments 
of every system. The sizes of the sliding window depend on the 
value of pool depth and quantity of selected lineaments. 
Data of special research are ascertained functionally 
interdependence of the extent and value of depth of breaks 
(Nechaev and other, 1991, Petrov, 1974, Rugich, 1977, Rugich, 
Sherman, 1978, Sankov, 1989, Chemishev, 1983, Sherman, 
1984, and other). The account of this dependence is used at a 
choice of the size of a window of averaging. For this purpose 
the analysis of distribution of potential of objects in researched 
area on occurrence depth will be carried out. The maps of 
density and total length of lineaments are defined with the help 
of sliding windows of averaging; the sizes of windows are 
defined proceeding from occurrence depths of the basic 
horizons of accumulation for prognosis pools. 
At a choice of the sizes of sliding window the quantity of 
lineaments in window is accountable factor. The calculating the 
quantity of lineaments occurring in a sliding window is 
necessary for determination of quantity of windows with the 
zero values. The quantity of the sliding windows with the zero 
values of graph tightness or total length of lineaments must not 
exceed 10% from a common quantity. It is defined 
experimentally. Otherwise maps of potential are impossible for 
interpretation and have small information for the prognosis 
research. 
In the process of prognosis researches and for geological 
interpretation of maps of closeness and total length of 
lineaments the method of spatial correlation of values of these 
maps with the pools (deposits) and structures selected by the 
geologic and geophysical data is used. 
For realization of methods and algorithms of analysis of 
lineaments fields are written the author's complex programs in 
Delphi. We developed programs for the decision of tasks 
which had not been included in well-known software’s. The 
programs are used to analyze lineaments orientation, excretions 
of the systems of lineaments, creation of maps of graph 
tightness and total length of lineaments, creation of maps of 
knots of crossing of lineaments and transformations of data. 
The data formats of our programs are compatible with well- 
known software. Calculation control and verification of the 
results are tested in GIS, ERDAS Imagine or Maplnfo 
Professional. 
The following sequence of operations was set in the total: 
1) Visual decoding of space images with use of the program of 
ERDAS Imagine. 
2) Translation of data vector for the format accepted in the 
developed program. 
3) Data analysis and receipt of results with use of the developed 
program. 
4) Construction of maps in an isohnes form by the Surfer program. 
5) Translation of the file of raster format got by Surfer program. 
For the control of calculations and verification of results the data 
in GIS-program are visualization. 
2.4. Basic prognosis method of oii-and-gas content for territory 
with remotely-sensed data 
The method of spatial-probabilistic prognostication is used for 
oil-and-gas content estimate of the territory. The program, based 
on this method, creates maps in the quantitative form for studied 
territory. This maps are used for predict potential oil and gas 
content of territory. The program uses any quantity of search 
features. The minimum area of prognosis potential are 
corresponded to pixel size of satellite image used for created of the 
prognosis maps. 
The complex informative features are formed in the beginning. 
For this purpose is used the program of spatial-probabilistic 
prognostication for calculating the probabilities of interconnection 
of informative features with the objects of prognosis Self 
descriptiveness of attributes is established by comparison of 
distributions of meanings of analyzed attributes within the limits 
of known objects of the forecast with distribution of their 
meanings which were defined for a uniform network in the most 
investigated territory. For comparison of distributions the Pirson 
criterion is used. In a case wide disagreement the functions of the 
relation of plausibility are used. On them the interval of meanings 
of an attribute is defined, to which the objects of the forecast are 
connected and the probability of interconnectivity of objects with 
the values of every search feature are calculated. Then the 
multidimensional functions of likelihood for complex analysis of 
all search features are used. The results of complex analysis 
prognosis of territory are maps of potential of oil-and-gas content 
in isolines. 
The next stage is containing the analyses of maps of prognosis of 
potential oil-and-gas content in isolines. Local perspective areas 
are selected with the use of expert appraised results. All 
information, which for diverse reasons was not used in the process 
of prediction, is used. As result we have the calculated potential 
values for selected areas. Then for calculated of the values are 
realizing ranking and are prepared the recommendations for 
conducting research on perspective areas. 
Characteristics of the spatial-probabilistic prognostication 
method are: realization of semantic control of the results on the all 
stages of works; possibility of removal of spurious of features and 
inexplicable results. 
The potential maps are created on the results of remotely-sensed 
data or in a complex with different geological explorations (if they 
are available). 
The important question is the authenticity of the prognosis 
results. Undoubtedly, only drilling can verily the reliability of the 
prognosis. It is rarely on the practice. If in the region are known 
pool areas, part of them are not used to estimate potential of 
territory. They are used as control points to verify the authenticity 
of search features in every case. The control points are determined 
in every case. 
2.5. Results of prognosis research 
These research methods were used to creation prognosis maps for 
oil and gas pools of the following provinces: West Siberian 
(Latitudinal Priobie and Yamalo-Nenetskiy autonomous region), 
Sakhalin (North-Sakhalin and West-Sakhalin pools), Timano- 
Pechora and Dneprovo-Donetsk. 
The explorations were conducted the south-east of the 
Dneprovo - Donetsk Province on a territory of about 1000 sq. km. 
Relief of research territory is hilly with by the many ravines. Small
