oa Implementation of passive seismic during the oil & gas exploration works in the Udmurt Republic, Russia

Currently, the level of oil production in the Udmurt Republic is on a declining trend, due to the depletion of large and medium-sized oil fields that have been operated for a long time. Therefore, the main challenge in this region is to stabilize & increase the amount of oil extraction by exploring more perspective low-field deposits. However, some problems complicate the process. Firstly, geological prospecting and exploration works, as well as drilling exploration wells, entail financial implications, increasing the accumulated cost of these works. Secondly, there may be some errors that often contain during the hydrocarbon reserves’ calculation process for such deposits. Passive seismic is proposed to become a solution to these problems. Use of this technology could decrease the amount of time required for hydrocarbon exploration and enable to reduce the exploration and development costs.
