An integrated approach to the selection of technologies for controlling water and gas inflow under the conditions of Yurubcheno-Tokhomskoye field

Authors: A.Yu. Presnyakov, I.Yu. Lomakina , T.E. Nigmatullin (RN- UfaNIPIneft LLC, RF, Ufa) , R.K. Razyapov , A.S. Sorokin (Vostsibneftegas JSC, RF, Krasnoyarsk)

Key words: water and gas inflow insulation, carbonate reservoirs, the design of repair and insulation work.

The presence of natural vertical and subvertical fissures in the reservoir of Yurubcheno-Tokhomskoye field, on the one hand, provides good hydrodynamic link between well and subhorizontal cavernous intervals, forming the main reservoir capacity, on the other hand, it can cause rapid gas pollution and flooding during well operation. At insulating gas and water inflows, the movement of plugging compositions in the formation can occur through the same fissures that allow the inflow of oil into the wellbore, and therefore the risk of losing the productivity of the formation is high. It is shown that in such circumstances it is advisable to use a series of compositions with the effect of uneven reducing the permeability, volumes of which are selected subject to developed technique of construction the design of repair and insulation works.
