Research Company offers performing forecast and estimation of presence of hydrocarbon fields by structurometric method. Structurometric method requires no field trips and provides significant time saving. Forecasts developed by structurometric method, in comparison with conventional exploration activities 3 times are more exact, by 1-2 orders more efficient, environment remains undisturbed. Root-mean-square errors of definition of deposit depths and thickness of oil and gas formation according to numerous test wells do not exceed 4-5 % (at depths up to 4000 m.). There can be discovered productive formations at depths of 7 km and more, and also on a shelf at sea depth up to 450 m. This method can be used rather productively by investors with the purpose of predictive estimations of resources of licensed sites and areas offered for right of land tenure.

APPLICATION OF THE STRUCTUROMETRIC ANALYSIS OF AERIAL AND SATELLITE IMAGES FOR THE FORECAST AND ESTIMATION OF HC POOLS AND MINERAL DEPOSITS Testing of the Method Application of the structurometric analysis of remote sensing data for the forecast and estimation of hydrocarbon fields was tested on various aerial and satellite imaging data. Black-and-white, color, and spectrozonal photographs and scanned, thermal, radar, and other images of the Earth’s surface including shelf zones with a sea depth up to 200-400 m were used.The practical testwork was conducted chiefly for the territory of the Russian Federation: West Siberia, northern European Russia, the Urals, the Volga region, North Caucasus, Central regions, Russian Far East, and the Kaliningrad Oblast. In addition, the method was tested on the petroliferous regions of Kazakhstan, Kirgizia, Japan, the Republic of Korea, US, Canada, Mexico, Paraguay, and Costa Rica.In the course of work, the possibility to use the forecast models for the solution of diverse problems related to the forecast and comprehensive characterization of license areas and individual oil and gas pools was confirmed.The structurometric analysis proved to be efficient for the strategic purposes such as the petroleum zoning of large territories (regions, republics, and countries). A case in point is the forecast of the petroleum potential of the Devonian deposits within the Astrakhan Arch, where several ultradeep wells were planned to be drilled. The forecast maps and cartographic models created by the structurometric analysis technique can be used for petroleum exploration in the vicinity of the existing, constructed, and planned gas and oil pipelines. The discoveries resulting from this purposeful exploration can provide a significant alimentation to the fuel flows and raise the economic efficiency of pipeline operation.

Structurometric analysis enables a purposeful oil and gas exploration in regions deficient in fossil fuels. An example is the prognostic estimate of the petroleum potential of the Tula Oblast. The obtained data can as well be used for the planning of underground gas storages.

A broad spectrum of the possible applications of structurometric data is primarily due to the fact that clients get ready-to-use informative materials such as photographic maps, geological sections, tables, and other graphics rather than raw aerial and satellite images, on which hydrocarbon fields are still to be found and the required characteristics are still to be determined. All of them are created with a due regard to the consumers’ wishes and contain the required comprehensive and fairly reliable forecast data sufficient to substantiate the launching of prospecting, exploration, and other activities in any particular area throughout the world. This method requires no field trips or preliminary field surveys and can be applied successfully even in the absence of geological or any other information. It can be applied not only in mature petroleum provinces, but also in frontier regions of the Earth.

This unique method is particularly attractive for the clients, because its economic efficiency is much higher than that of all customary methods, including gravity, seismic, and magnetic surveys and exploratory drilling.

Using, in fact, nothing but remote sensing data even for a frontier (preliminarily unexplored) territory interesting for the client, a rough-and-ready forecast of its petroleum and mineral potential can be given and the volume, depth of occurrence, and other parameters of mineral deposits can be estimated including the relative difficulty of vertical drilling conditions and recommended well locations.

Another sphere of application of the structurometric analysis is the appraisal and improvement of exploration data, including seismic and drilling data (extension). The forecast of petroleum productivity in the Kaliningrad region can serve as an example. The obtained data indicated the occurrence of many potentially petroliferous structures in that territory, which could not be identified by conventional methods. Some of them are much larger than the explored HC fields.

The Lukoil company furnished seismic and exploratory drilling data on a structure in which a well (one of the four) discovered and tapped a presumably 10-meter-thick oil reservoir.

Our analysis showed a probable existence of two more thinner reservoir units within this potential structure and a possibility to tap the lower unit by well no. 10 that had been considered dry, and another oil pool of commercial significance was identified to the west of that structure.

The work on the territory of Eastern Kazakhstan proved the applicability of the structurometric analysis to the exploration of thin stacked oil and gas reservoirs interbedded with multiple non-commercial HC-saturated beds. It was confirmed later by the analysis of multi-pay oil and gas fields in the Orenburg Oblast, South Sakhalin, and Komi Republic.

Another advantage of the method is the possibility to apply the structurometric analysis procedure for offshore HC exploration. It was tested by predictive HC appraisal and mapping in the Caspian, Baltic, Japan, and Yellow seas, near the western coast of Canada, and in the Gulf of Mexico.

All our clients were satisfied by the forecast estimates. The geologists that adhere to customary methods were often surprised and even fazed by the accuracy of the forecast, and, being sceptic about the results, hardly ever accepted them.

The report on the investigation and analysis of geological structures at six well sites in the Gulf of Mexico (under a contract between the Moscow State University and Global Drilling Investigation Co Ltd., Gibraltar) was subjected to a particularly biased revision. The final report was submitted to a special examination.

Formerly, the scarcity of evidence for the successful application of remote sounding methods in HC and mineral prospecting led many scientists to doubt the possibility to obtain reliable and versatile data on mineral resources from satellite images.

Disagreement with such a skeptic point of view induced a group of scientists of the Moscow State University to undertake the development of an original system of algorithms for the structurometric analysis of multispectral satellite images with the purpose of HC and mineral exploration and a comprehensive estimation of the deposits.

The structurometric analysis came into being several decades ago as a method of geomorphologic interpretation of the aerial and satellite images of the Earth’s surface.

At present, the experience of investigations enabled us to establish a new mechanism for a task-oriented recognition of various areal or structural features from remote sensing data.

A systems-based methodology of structurometric analysis was developed and a universal methodology of computerized scientific analysis and forecast of the location and other parameters of oil and gas pools and other geological objects located as deep as 10 km and even more was created.

Fundamentals of the Structurometric Analysis of Remote Sensing Data.

The structurometric analysis, like seismic methods, is based on computerized interpretation of seismoacoustic signals arriving from the Earth’s interior. Seismic methods employ the signals produced by artificial seismic impact on the crust (explosions). Based on the analysis of the travel times and patterns of the waves reflected from rock strata, seismologists determine the depth of occurrence of rock seams with certain reflecting properties and thereby predict the presence or absence of HC reservoirs.

The structurometric analysis is also based on the interpretation of the data related to the travel of seismoacousting waves through the Earth’s interior. But this method, unlike seismic sounding, does not require field surveys and does not exert a harmful active seismic impact upon the Earth’s interior. The structurometric analysis is based on computer interpretation of the natural seismoacoustic waves of the Earth, indirectly reflected in remote sensing data.

The sources of these waves are the deep subsurface zones of the Earth, which emit seismoacoustic waves continually, year by year. Upon reaching the Earth’s surface, these waves transform it to a certain extent. Special computer analysis enables the determination of the depth of signals arriving from rock seams with different properties and distinguish the waves arriving from HC reservoirs.

The possibility to forecast oil and gas reservoirs from surface traces is provided by a cumulative effect of seismoacoustic waves continually arriving from oil and gas reservoirs over thousands and millions of years. Continuous radiation gives rise to more or less distinct ring and linear structures and geopathogenic zones with specific geophysical properties, reflected in remote sensing data.

However, all these phenomena, resulting from the influence of oil and gas fields, are reflected on satellite images in a hidden, indirect form. Therefore, their recognition requires a number of complex procedures of computer-based structurometric systems analysis.

The basis of the structurometric analysis of HC reservoirs is the recognition of the contact between the pay zone and the caprock (the rocks in the roof of oil and gas reservoirs). The zone of contact between rocks with different capacity for emitting seismoacoustic waves is the main target of structurometric analysis. The recognition of this zone enables one to study the changes in seismoacoustic waves as they travel through the contacts between rocks with different physical properties and determine the depths at which these changes are detected.Each contact zone shows an individual pattern of effect upon the surface, which is superimposed upon the patterns of other contacts at different depths. Therefore, each part of the Earth’s surface bears a vast number of ring structures and traces of the effect of the Earth’s interior upon its surface. Consequently, the traces of effect of each rock seam on satellite images are usually masked and indistinct, because each of them overlaps the effects of other seams.

The objective of scientific investigation is the search of the criteria enabling one to reliably distinguish the signals corresponding to petroliferous rocks and ignore a multitude of other signals arriving from the rocks that do not contain oil or gas reservoirs in conditions of the studied sector of the Gulf of Mexico. This is possible only if the structurometric analysis employs specially adjusted fine computer procedures, which enables one to detect even the weakest and disguised seismoacoustic signals, perform their computer processing, and thereby determine the depth of occurrence, thickness, composition, and other properties of the studied rocks.

The structurometric analysis becomes particularly difficult when applied, e.g., to offshore areas, very deep occurrence of pay zones, and the stacked reservoirs within the presumably petroliferous structures.

The seismoacoustic waves grow increasingly distorted and transformed with distance from the source as they travel from the deep crustal levels to the surface. The extent of distortion of the primary seismoacoustic waves depends on rock properties variation in the sequence and the number of oil reservoirs. An increase in the latter leads to an increase in the number of interfaces between rock masses with contrasting properties, reflected on satellite images.

Brief Description of Analysis Procedure

The structurometric analysis of remote sensing, cartographic, geological, and other data includes some complex technological procedures, new software, and sophisticated intellectual resources.

The methods and techniques of aerial and satellite image processing, computerized interpretation, and cartographic modelling are arranged into a single algorithmic system. The system employs various software products: original program-algorithmic blocks, commercial geoinformation systems, and special graphic modules that enable one to combine conventional geologic mapping with a multiparameter three-dimensional graphics etc. The whole integrated system of programming techniques and the main features of the applied software are ORIGINAL and HAVE NO EQUIVALENTS IN WORLD PRACTICE.

The necessity to work out and apply a wide spectrum of special sophisticated programs is caused by the extreme difficulty of the recognition and reliable identification of HC pools based on remote sensing data, which are not directly reflected in the structural features of the Earth's surface.

Our experience of investigations suggests that it is impossible to obtain information related to HC exploration by means of a single, even most complicated and universal program. Therefore, a number of software module workflows were created. Application of these workflows enables one to gradually pass from one task to another.

For instance, even the initial aerial and space image processing employs the following software modules:

programs for preliminary gradation and structurometric correction of the picture field;piecewise Fourier transform of the picture, enabling one to detect regions with the lowest amplitudes of the harmonic components of the initial picture;screening of the initial structural picture, i.e., its transformation into binary form using the Evans algorithm that detects regions with a negative Gaussian curvature;recognition of the background network of ring structures (numbering tens and hundreds of thousands in a square kilometer), whose mutual onlapping and combinations produce an intricate interference pattern;matched filtering of the binary structural picture aimed at the recognition of ring and elliptical structures corresponding to HC pools etc.

Estimations of Undiscovered Resources of Hydrocarbon Raw.

An estimation of undiscovered resources of hydrocarbon raw is realized in three steps. Each of the step differs from others, having a different level of both detailedness of the initial space information, and, hence, detailedness of the resulting estimations.

On the preliminary stage of research, the reference space data of 1: 200000 -1:1000000 scale (MSU-SK instrument, "RESURS-O" satellite [3-5]) is used. The data prosessing results in:

• estimation total productivity of oil resources for a specified territory, with a preliminary estimation of oil reserves (mill, ton), gas (bill.cu.m.), gascondensate (mill, ton);

• pre-forecast (first-step iteration) of the potential area of fields, containing hydrocarbon raw, with estimations of:

-   sizes of oil, gas and condensed gas deposits (mill, ton; bill.cu.m.);- depths (relative and absolute values) of productive strata (m);-  thickness of strata(m);-  concentration of hydrocarbons per stratum (%).

At licencing activity of plots, the reference space data of 1:50000 -. 1:1000000 scale (MSU-E instrument, "RESURS-O" [3-5]) is processed. As a result, the following information is available:

• forecast (second iteration) of potential structures, containing hydrocarbon raws, with estimated:

- boundaries of potential pays (commercial deposits);- volumes of oil, gas and condensed gas deposits (mill, ton; bill.cu.m.);- depths (relative and absolute values) of productive stratum roofs (m);- thickness of strata(m);- concentration of hydrocarbons per stratum (%);- quality properties of hydrocarbon raws (density, content of sulfur, paraffin's, etc.).

To ensure drilling operations, at the preparation activity phase the reference data of 1: 5000 - 1: 10000 scale (MK-4, KFA-1000 instruments, "RESURS-F" [6, 7]) must be processed. The activities will result in:

• forecast (third iteration) of potential structures, containing hydrocarbon raws, with estimated:

- precise boundaries of potential pays (for each productive stratum);-   volumes of oil, gas and condensed gas deposits (mill, ton; bill.cu.m.) - total and for each productive stratum;- depths (relative and absolute values) of productive stratum roofs (m);- thickness of each stratum (m);- the concentration of hydrocarbon for each stratum (%);-quality properties of hydrocarbon raws (density, content of sulfur, paraffins, etc.) for each stratum and a specified unit of explored structures;

• recommendations on the arrangement of drill holes with taking into account the above estimations and a forecast on environment and on-site geophysical conditions (including effect of fractures and geo-nosogenic structures, occurenceof local seismicity regions, geochemical anomalies etc.)

Validation of the Technique for Oil, Gas and Minerals Exploration.

The efficiency of the proposed technique was validated with tjie results of a pilot ground survey of a territory within the Satinsk range (Kaluga oblast, Russia) of Geographical faculty of Lomonosov MGU Kaluga oblast, Russia) (fig. I). At present, -it should be emphasized as an advantage of the technique- it is already essentially developed and has passed a serious tests during the imagery analysis executed for a number of regions in Russia (Kaliningrad Oblast, fig. 2-3, table 1-2), east Kazakhstan and Canada. Such a domestic oil giant as LookOil company has shown her interest to the technique. By order of that company a’ detail mapping was carried out for the company's territories that confirmed the deposits, found out early, and revealed new beddings and flat-lying stratums of oil.

Results of the relief mapping of parent materials, a territory within the Satinsk range (Kaluga oblast, Russia) of Geographical faculty 'of Lomonosov MGU, on the basis of a picture of annular structures:

a - current relief in the topographic map of 1:10 000 scale;

б - parrent relief in the topographic map of 1:25 000 scale, resulted from drilling data;

в - parrent relief, designed by Yu.I. Fivenskiy under the annular structures.

So, there are potential customers for space prospecting information, acquired by specialized facilities and properly processed. The submitted technique for structural analysis is a validated tool that is available to meet the market requirements.

3-13 sites, recommended for wells (if 13 wells - 53.7% recovery of deposits). 5 and B are the top-priority sites, recommended for wells.Fig. 2

Onboard Spectrometric System' for Prospecting.

So far, the said technique was tested mainly on the aero-survey data. However, the technique will provide higher cost efficiency if it uses space information of earth remote sensing systems. The higher spatial and spectral resolution of satellite imagery is, the more sophisticated structure analysis of beddings and, hence, the more accurate forecast and estimations of natural resources will be available under the technique. Being based on the space survey data only, the approach will give an opportunity to solve the economic problems mentioned above (in particular, exploration and estimation of the sizes of oil-and-gas fields and other mineral deposits), with no expensive and inefficient gound-based prospecting operations.

Since 1998, within the framework of the Russia Federal Space Program, activities on development of an onboard spectrometric system for prospecting have being carried out.

Structurometric analysis of aerial and space photographs for the purpose of forecast and estimation of hydrocarbon fields is based on the patent No 02-Д/02 'Minor ring-shaped structures of friable deposits of the Earth's crust'.

Besides that through our research it has been shown, that «Olympic» structure is double-layer and the second layer is on 10-12 meters below the upper a productive layer (as customers

considered - the only thing).We have revealed also, that their second, so-called "empty" well №3 has appeared to be productive

after additional drilling. These materials are presented by us (Sadovnichij V.A., Utkin V.F., Zhukov V.T., Lazarev G.E., Fivenskij J.I., etc.) in the report on small satellites in USA.

2. Under the request of industrialists of the Mexican United States has been executed the predictive estimation of deposits of hydrocarbons for area of two installed platforms in gulf of

Mexico. Wells, which had been drilled earlier by the customers up to depth of 6000 meters had appeared to be empty. Depth of a sea gulf in these points reached 400 m. ( Fig. 4)

Fig. 4

Our predictive estimation of structures of each deposit has shown, that wells are drilled on the edge of layers (Fig. 5).

According to our development both these, significant on resources, are four-layer structures, but the drilled wells have passed outside of layers.

On Fig.5 is shown an erroneous position of well 1 and coordinates of a point 11 where it is necessary to move the drilling platform .

We have executed deep research of a deposit structure (a Fig. 6) and have shown its multilayer structure.

On a contour A-B (the second section C-D has been also investigated) are shown all layers of oil field Alak and two geodynamic fractures.After studying the presented materials under the request of the Customer we had been developed another four objects with definition of installation sites for platforms in gulf of Mexico. Accounting materials have been passed to the Customer - to company «Global Drilling Investigation Co Ltd » on six points where installation of drilling platforms is recommended (See the covering letter of the Moscow State University concerning delivery of documents to the customer).

3. The comparative analysis of predictive estimation of hydrocarbon deposits of Timano-Pechora oil-and-gas province (See Fig. 7).

Fig. 7

The subimage of this territory shows, that predicted with the help of structure-metric method:- Deposits in 18 cases from 20 confirm the structures reconnoitered by geologists;- The borders of structures revealed by us more detailed, than shown by traditional geological prospecting which integrated cover some separate structures; so for example borders of structures in the southeast №37 and №62 revealed by us and traditional geological prospecting completely coincide; and two structures №12б and №43в, revealed by us, traditional geologists show in one structure; - Many new structures have not been revealed by traditional geological prospecting;Predicted by structure-metric method resourses of hydrocarbonic raw material, in each deposit, are accompanied by a tentative estimation of its volumes. The structures shown by traditional geological prospecting do not contain such information. 

4. Predictive characteristic of Vostochno-Vejakskoe deposit on the basis of structure-metric method analysis of aerospace information (See Fig. 8). Map of the deposit and the structure A-B, noted on

this map. Fig. 8

The traditional geological prospecting has detected borders of only one dome of Vostochno-Vejakskoe deposit, which are shown on the map by a continuous green line.On the presented map it is given, developed by us predictive characteristic of Vostochno-Vejakskoe deposit, convincingly showing fuller and more detailed predictive estimation of a deposit. On the map are shown the revealed new areas of the given deposit and total capacities of layers of three productive parts of this uniform structure stretching on a parallel more, than on 10 kilometers.

Also it is presented the geological structure of Vostochno-Vejakskoe deposit. On the structure are shown effective capacity of productive layers and absolute depth of occurrence of productive layers roof . 5. As an example proving high efficiency of a method of Small Ring Structures for studying of a deep structure of an earth's crust, on fig. 9 are shown results of structure-metric definitions on arid zone (sandy desert - the United Arab Emirates). On the figure are presented results of definition of depths of occurrence of the basic lithologic borders of section of layers of sedimentary rocks in vicinities of a geological well on a ring skeleton of a two-dimensional structure in length of 2,55 km and by width ±850 m, passing its axis through the well. An initial material - the space picture Landsat-7 received in integral (izopanchromatic) zone with the sanction of 15 m on district. Structure-metric profile precisely records buried graben, not being reviled in morphology of modern district. Besides attracts attention higher detail (in comparison with a lithographic column of a well) of imagery thematically significant litilogical borders of sedimentary rocks. On the resulted profile it is shown, that if the well has been installed in 150 meters from drilled, water discharge could be essentially increased.
