HIGH-VISCOSITY OILS: AN ANALYSIS OF REGIONAL AND TIME CHANGES
http://www.ogbus.ru/authors/PolishukYu/PolishukYu_1.pdf (in Russian)
Paper is devoted to analysis of reviewed materials on studies of physic-chemical properties of viscous oils, which are considered as main reserve of oil production for future years. Completed spatial analysis of regional regularities has shown that the most viscous oils in Russia are in Timano-Pechora and Precaspian oil-bearing basins. Analyses of regularities of oil viscosity change depend on depth show oil viscosity decreases with depth growth. It is shown that maximum value of oils viscosity is in Mesozoic rocks and its minimum value is in Precambrian rocks. In average, high viscous oils is heavy, sulfur, high resin, high asphaltenes ones and with small content of paraffin's and content of IBP 200C.

A NEW TECHNOLOGY OF GRAVITY ANOMALIES INTERPRETATION ON EXPLORATION FOR OIL AND GAS
http://www.ogbus.ru/authors/Bychkov/Bychkov_1.pdf (in Russian)
Suggested a new technology of gravity anomalies interpretation on exploration for oil and gas that makes it possible to divide the total field into components caused by different units of geological section. The technology is based on essentially new method of potential fields data interpretation - system of vector field scanning. Transformation of vectors of the total horizontal gradient, their scanning in sliding window followed by integration of different components enable to separate in detail the sources of field anomalies in lateral and depth directions.
Joint use of vector scanning system, gravity modeling and correlation analysis makes it possible to create a geological model adequate to a priori geological data and observed gravity field. Effectiveness of the technology is shown on an example of gravity data interpretation in difficult geologic conditions.

THE REASON OF THE ORIGIN OF "THE STARTING EFFECTS" DURING THE REALIZATION OF STANDARD GAS DYNAMIC RESEARCHES AT KOMSOMOLSKY GAS FIELD
http://www.ogbus.ru/authors/Maltsev/Maltsev_1.pdf (in Russian)
There is considered the problem on the effect of the man-caused causes on the results of standard gas-dynamic researches. The problem appears under the following circumstances: 1) using of modern high-precision equipment; 2) existence of clustered technological series of gaseous bores; 3) using of computer processing of research results. “The starting effects” action most obviously emerges when recording the LPS (line of pressure stabilization).
The influence of “the starting effect” during the carrying out gas-dynamic researches should remove in the following way: equipping the torch line end of the gaseous well cluster by electric valve gate in an explosion-proof view with remote control; inserting the corresponding amendments into the regulation on realization GDR (gas dynamic researches); carrying out everywhere the substitution of the standard computer processing of research results of GDR by their detailed complex analysis.

THE MAIN REASONS OF ORIGIN OF ISOLATING COATINGS DEFECTS
http://www.ogbus.ru/authors/Harisov/Harisov_2.pdf (in Russian)
In the article analysis of the basic reasons of origin of isolating coatings defects is carried out. The main reasons are:
- application of poor-quality or inappropriate isolating materials;
- poor-quality drawing of primer onto a pipeline;
- defects arising at drawing of polymeric isolating tapes;
- defects arising at isolating and stringing works and backfilling of a pipeline;
- mechanical influences of ground during operation resulting in shearing or stretching stresses in isolating coatings, followed by stress cracking and formation of corrugations, scorings, scratches and flutes;
- physicochemical influence of ground, influence of surface active components of ground colloidal environment resulting in evaporation and washing away of plasticizing agents from isolating coatings;
- misuse of a pipeline (sharp temperature difference of product transported, pumping of a product with temperature above the designed one, etc.);
- poor quality of electrochemical protection measures (the potential difference "pipe - ground" is higher or lower than the admitted one, etc.);
- non-adherence to the modes of isolating materials drawing in winter conditions - disturbance of the modes of pipeline preheating, primer drawing, isolating coatings drawing and storage;
- freezing of pipeline isolating coating together with water saturated ground.
