Abstract
At the design stage of wastewater injection in oil/gas-condensate Yamal and Nadym-Purovskoye inter-fluve fields, one of the most important tasks is to forecast the absorption capacity of the aquifer. In connection with this a very important task is to estimate the permeability and porosity parameters of this horizon. In this paper an assessment of permeability and porosity parameters of absorption by three methods is proposed: pres-sure buildup curve, by the experimental cluster injections databy well logs.

Abstract
Hydrogeochemical conditions of the West and East Messoyakhsk fields are discussed in the article. These conditions of the complex hydrogeological Mesozoic basin are important in the formation and preservation of oil and gas deposits. The geological structure is characterized by the presence of a large number of disjunctive dislocations. The fields belong to the Elysion geodynamic water drive system - the Omsk-Gydansk structural zone. This determined the conditions and intensity of oil and gas generation.

Abstract
This paper presents the major results of the research study, including the depositional environments evaluation, lithofacies and petrophysical simulation, and the application of a complex approach to the reservoir properties distribution prediction, reservoir geometry and boundaries estimation in undrilled zones of the Lower Miocene reservoirs of the Central Dragon oilfield (Cuulong basin, Vietnam offshore). These data are actual for further exploration drilling objectives, reservoir stimulation and EOR design.

DRILLING OF WELLS AND FIELDS DEVELOPMENT

39-43 1081
Abstract
The paper demonstrates that the hydrophilic behavior of productive formations is primarily determined by the water retaining capacity. Especially it concerns carbonaceous reservoirs characterized by a lack of or low gel cement content. In terrigenous reservoirs the water retaining capacity is greatly affected by the variability of gel cement mineral composition. At a permanent mineral composition of interstitial clay there may be present a correlational relationship between the hydrophilic behavior and water retaining capacity of a productive reservoir.

Abstract
Currently, metrology is an important element of any industry. Under these conditions, the accuracy of testing and calibration of measuring devices becomes critical. Due to the high accuracy of modern measuring instruments, human factor can play a significant negative role in the calibration process. Therefore, the use of modern tools, such as a data logger, can significantly improve the quality of the process, reducing staff functions to process control.

Abstract
The analysis of a temperature profile in the trunk of a vertical well when pumping liquid was carried out. The paper describes the application of an algorithm of the inverse numerical transformation with use of Gaussian quadratures (Iseger's method) to a task about a temperature profile under conditions of a short-term liquid pumping into the well. Analytical dependences are constructed on the basis of a method of the Laplace-Carson integral transformation of decomposition. The inverse transition is carried out on the basis of numerical inversion with use of Gaussian quadratures (Iseger's method).

Abstract
The research results on the recovery of drilled solids and spent drilling mud with the use of phosphogypsum in combination with the humicagent «Rostok» showed that the resulting soillike environment can be used while recultivating slurry ponds and disturbed lands. Adding extra 5-20 % of spent drilling mud didn’t affect the chemical composition of the soil significantly. Using the humicagent «Rostok» favorably impacts the development of plants, besides the formation of a viable phytocenosis takes place with the significant increase of phytomass of vegetative aerial shoots by 28-31 %.

Abstract
The paper discusses modeling of oil migration processes in the soil with the use of x-ray microtomography to optimize the process of oil spill elimination. To conduct the study, the most common soils on the territory of Tyumen region, i.e. sandy and sandy loam soils, were taken. Then a process of an oil spill was simulated on the micro model. As a result of the analysis, 3D-models of spatial distribution of oil in the soil were created and the depth of oil penetration into the ground was determined.
