Combination of strat-based modeling & distance to boundary (inversion) methods implementation in geologically complex formation K1ne-2 of Balgimbaev oil field, Kazakhstan

Year by year drilling of horizontal wells becomes more and more popular way of the field exploration. For instance, at the beginning of XXI century the quantity of drilled horizontal wells from the whole amount was just about few percentages, if to say that nowadays this number is getting closer to 60%. Despite on that fact, that designing and exploration of oil & gas fields are such laborious processes, the main problem is still lies on the low level of EOR. Nowadays geosteering becomes an essential part of well drilling and increases the level of well targeting, therefore it enhances the level of extracted hydrocarbon fluid. Analyzing drilling datas, received in a real time from the wellbore, geosteering provides an opportunity to correct the planned trajectory of the well instantly and therefore make sure that the well stays in a target zone.
