Abstract

​

Geological and fluid flow models have been created for faulted Upper Devonian terrigenous sediments of Elabuzhskoye oil field. Reservoir simulations have been run to predict oil production performance of Upper Devonian terrigenous reservoirs. Production forecasts have been made for two field development scenarios, depending on current development status of the production zone, with the aim to optimize field development system. Production decline observed over the past fifteen years necessitates drilling of new wells. Thus, the authors of the paper have used the results of reservoir simulation study to come up with a drilling strategy providing for selective placement of new wells. The drilling program implies drilling of 25 production and four injection wells, unplugging of two abandoned wells and sidetracking of two lateral holes.

fault, terrigenous reservoir, Bashkirian stage, geological and fluid flow models, interpretation of well logging data, relative permeability, history matching, sidetrack drilling
