The article discusses development of the backfill composition based on OTDV «Mikrodur». A method of mathematical planning of the experiment is described used to prove the optimal formulation of water isolation composition and the processing of the study results by application of the procedure of “full factorial experiment”. The results of the study by computer microtomography of the formed plugging stone are also presented.

The paper presents a method for arrangement the oil and gas wells overhaul repair with attraction of service companies and proves the effectiveness of the proposed scheme of jobs organization and gives a determination of well work-over services.

The article considers the history of development of oil and gas resources of seas and oceans, and prospects of the Arctic off-shore fields development. The analysis of the project solutions on development of the off-shore gas and gas-condensate fields in the Tyumen region north has been carried out. The technology solutions are proposed aimed on completion of prospecting wells from the ice islands at time deficit using drill rigs, as well as on completion of wells with using the preventing units.

The problem of fire and blowout safety during the construction, operation and repair of wells during field development of oil and gas in the far north of Western Siberia. To ensure the safety production facilities offer specific preventive measures, which are aimed at the realization of the efforts of existing fire and blowout units.
