Abstract

Estimation of reserves, current re-estimation of oil in place, and reserves assessment require considerable detailed research efforts for substantiation of volumetric parameters. In this context, minimization of time and labor intensity of reserves estimation while ensuring the accuracy sufficient for field applications becomes critical. Rapid assessment of original oil in place is applicable at various stages of exploration activities. Seismic interpretation capabilities and standard regressive dependencies, constructed based on strong correlation of volumetric parameters, enable estimation of in-place reserves and resources without the need for spudding new wells, and ranking of drilling sites in order of priority. In this experimental research, the authors will resort to rapid assessment method for estimation of reserves and resources of Tulskian terrigenous oil reservoirs in 10 oil fields operated by TATNEFT. Developed in West Siberian oil fields, this method will be put into practice in Volga-Ural petroleum province for the first time ever.

Key words:

estimation of reserves, rapid assessment of reserves, correlation coefficient, reserves per well, net oil-saturated thicknesses, regressive dependencies.
