Abstract According to the detailed analysis of geology and hydrogeology in the Yurubcheno-Tokhomo hydrocarbon play (YTHP) the Lower Cambrian Osa horizon has been shown as suitable for the disposal of large volumes of produced and wastewaters. A 3D-model of filtration between the injection (disposal) well and reservoir was used to estimate the contribution of the industrial effluent injection. The highest industrial change in the mineralogical composition and porositypermeability of reservoir was revealed during treated effluent disposal. Zone of industrial metasomatism was up to 800– 840 m by the end of the fifth year of landfill operation. Keywords Hydrogeology . Effluents . YTHP . Physicochemical simulation . Disposal

current contamination of the environment (Ahmadun et al. 2009; Agwa et al. 2013; Brower and Visocky 1989; Bukaty 2009; Carr et al. 1986; Grishagin et al. 2010; Haberfeld 1991; Hayes and Arthur 2004; Kartsev and Nikanorov 1983; Sevastiyanov and Zakharov 2007; Warner and Orcutt 1973; Warner and Lehr 1977). Hopes to increase oil and gas production are associated with the East Siberian petroleum province restricted to Siberian Craton and especially with a group of fields in the Yurubcheno-Tokhomo hydrocarbon play (YTHP) due to the construction of the Eastern Siberia–Pacific Ocean pipeline (ESPO) (Fig. 1). Problem of industrial waste disposal must be solved prior to production. Liquid waste disposal calls for building land for special storage warehouses or additional production for cleaning or recycling oilfield waters. Widely used evaporation method is no longer suitable due to significant financial costs, air and groundwater pollution, and long-term remediation of disposal sites (Pettyjohn 1971). Effluent treatment also requires efforts and capital costs; furthermore, existing methods of purification and decontamination are not advanced enough in technology. Accumulated water injection in the reservoir pressure maintenance system (RPM) helps to minimize the risk on the oil fields under long-term development. Disposal is a great problem on new fields that have no RPM.
