The 2-nd international seminar on geothermal volcanology (Geothermal Volcanology Workshop 2018) will be held from 05 to 08 September 2018 in Petropavlovsk-Kamchatsky, Russia. Kamchatka is an active volcanic, seismic and hydrothermal region. Active volcanism is accompanied by magma injections into host structures, magmatic fracturing and the formation of hydrothermal systems adjacent to volcanoes. Engineering study of productive geothermal reservoirs is a necessary condition for their effective use for heat and power supply. Geomechanical analysis of the magmatic fracturing regime with seismic data is extremely important for predicting volcanic activity. It is also useful for analyzing the productivity of geothermal reservoirs and as the analog of hydrocarbon reservoirs development with hard-to-recover reserves. The interdisciplinary focus of this workshop will bring together scientists to solve problems which transcend the framework of international borders.

Geothermal Volcanology Workshop 2018 provides a unique opportunity to meet with other scientists working in the Far East segment of the North-West Pacific as it makes an excellent presentation for those willing to participate in research of this unique region. In 2018, the meeting will begin the day after the start of the 2-nd International Geothermal Conference GEOHEAT will combine the efforts of scientists for geothermal energy research in the areas of modern volcanism.

    Koryaksky Volcano’s Dyke Fields & Thermal Mineral Springs

    The field trip lasts 10 hours (from 9-00 to 19-00). Number of participants is up to 10. Map of the area and root points (Figure 1): IVS FEB RAS – Avachinsky Base /IVS Base (AVH) – IVS FEB RAS (track-car); Avachinsky Base (AVH) – Dyke field on the south slope of Koryaksky volcano – Koryaksky Narzan (К8) – Koryaksky Narzan (К2) – Koryaksky Narzan (К1) – Isotovsky Hot Spring (IS) - Avachinsky Base (AVH) (helicopter). Foods: box lunch & Koryaksky Narzan water (K1).

    The trip costs 15 000 rubles per one participant. Prepayment on registration desk on Sept. 4 th 2018 in IVS FEBRAS. The number of participants is up to 10. The priority to participate in the field trips is given to those who earlier submitted an extended abstract and PPT.

Legend: (1) The summits of the Avachinsky, Koryaksky, Kozelsky, Arik, and Aag volcanoes; (2) Avachinsky, Koryaksky, Kozelsky volcanoes and their eruptive products; (3) Pinachevsky extrusions Q2-3; (4) thermal features (for details, see Table 1): FA - fumaroles on Avacha Volcano; FK - fumaroles on Koryaksky Volcano; K1, K2, K3, K7, K8 - thermal mineral springs of Koryaksky Narzan; IS - Izotovsky; VD - Vodopadny; CH - Chistinsky; Va - Vakinsky; (5) deep hydrogeological wells; (6) KB GS RAS seismograph stations; (7) dykes traced at -3000 masl below Koryaksky Volcano and 1500 masl below Avachinsky Volcano; (8) glaciers. Note: The isolines show the topographic surface, and the ticks along the axes represent intervals of 5 km.

    The Avachinsky-Koryaksky volcanogenic basin (Figure 1), which has an area of 2530 km 2, is located 25 km from Petropavlovsk-Kamchatsky City and includes five Quaternary volcanoes (two of which, Avachinsky (2750 masl) and Koryaksky (3456 masl), are active), and is located within a depression that has formed atop Cretaceous basement rocks. Magma injection zones (dykes and chamber-like shapes) are defined by plane-oriented clusters of local earthquakes that occur during volcanic activity (mostly in 2008-2011) below Koryaksky and Avachinsky volcanoes at depths ranging from -4.0 to -2.0 km and +1.0 to +2.0 km, respectively. Water isotopic (δD, δ18O) data indicate that these volcanoes act as recharge areas for their adjacent thermal mineral springs (Koryaksky Narzans, Isotovsky and Pinachevsky) and the wells of the Bystrinsky and Elizovo aquifers. Carbon δ13С data in СО2 from CO2 springs in the northern foothills of Koryaksky Volcano reflect the magmatic origin of CO2. Carbon δ13С data in methane CH 4 reservoirs penetrated by wells in the Neogene-Quaternary layer around Koryaksky and Avachinsky volcanoes indicate the thermobiogenic origin of methane.

    Mutnovsky and Paratunsky Geothermal Areas

    The field trip lasts 10 hours (from 9-00 to 19-00). The number of participants is up to 10. Map of the area and root points (Figures 2 & 3): IVS FEB RAS – V-Paratunsky hot springs – IVS FEB RAS (track-car); V-Paratunsky hot springs – Vilyuchinsky Volcano – N-Zhirovskoy hot spring (16) – Voynovsky hot spring (16) – V-Mutovsky GeoPP 12 MWe – Mutnovsky GeoPP 50 MWe – Dachny Steam Jets (7) – Dyke Field in Mutnovsky Volcano Crater (3) – Vulcannaya River Waterfall 60 m – Cold Springs in Gorely Volcano - V-Paratunsky hot springs (helicopter). Meals: box lunch & Silver Creek water (K1).

    The trip costs 25 000 rubles per one participant. Prepayment on registration desk on Sept. 4 th 2018 in IVS FEBRAS. The number of participants is up to 10. The priority to participate in the field trips is given to those who earlier submitted an extended abstract and PPT.

    The Mutnovsky geothermal area is part of the Eastern Kamchatka active volcano belt. Mutnovsky, 80 kY old and an aging strato-volcano (a complex of 4 composite volcanic cones), acts as a magma- and waterinjector into the 25-km-long North Mutnovsky extension zone (Figure 2). Magmatic injection events (dykes) are associated with plane-oriented MEQ (Micro Earth Quakes) clusters, most of them occurring in the NE sector of the volcano (2 x 10 km 2) at elevations from -4 to -2 km, while some magmatic injections occur at elevations from -6.0 to -4.0 km below the Mutnovsky production field. Water recharge of production reservoirs is from the Mutnovsky volcano crater glacier (+1500 to +1800 masl), which was confirmed by water isotopic data (δD, δ18O) of production wells at an earlier stage of development. The Mutnovsky (Dachny) 260-310°C high-temperature production geothermal reservoir with a volume of 16 km 3 is at the junction of NNE- and NE-striking normal faults, which coincides with the current dominant dyke injection orientation. TOUGH2-modeling estimates of the reservoir properties are as follows: the reservoir permeability is 90-600 e-15 m 2, the deep upflow recharge is 80 kg/s and the enthalpy is 1420 kJ/kg. Modeling was used to reproduce the history of the Mutnovsky (Dachny) reservoir exploitation since 1983 with an effective power of 48 MWe by 2016. Modeling also showed that the reservoir is capable of yielding 65-83 MWe of sustainable production until 2055, if additional production drilling in the SE part of the field is performed. Moreover, this power value may increase to 87-105 MWe if binary technologies are applied. Modeling also shows that the predicted power is sensitive to local meteoric water influx during development. Conceptual iTOUGH2-EOS1sc 5 thermal hydrodynamic modeling of the Mutnovsky magma-hydrothermal system as a whole reasonably explains its evolution over the last 1500-5000 years in terms of heat recharge (dyke injection from the Mutnovsky-4 funnel) and mass recharge (water injection through the Mutnovsky-2 and Mutnovsky-3 funnels) conditions as previously mentioned.

    The Paratunsky low temperature geothermal field (Figure 3) has been operating since 1964. During the period of exploitation from 1966-2014, 321 Mt of thermal water (Cl-Na, Cl-SO4-Na composition, M up to 2600 ppm) with temperatures of 70-100оС was extracted and used for district heating, balneology and greenhouses. The structure of the 40 km 3 Paratunsky low temperature (80-110°C) geothermal volcanogenic reservoir was geometrically characterized, hot water upflow regions and the 3D permeability distribution were identified with hydrogeological data, and the distribution of the feed zones and 3D temperatures were constrained by 3D spline approximation. Water isotope and gas (N 2, 96-98%) data analysis indicated that the main recharge region of the Paratunsky geothermal reservoirs is the Viluychinsky Volcano (2173 masl) and adjacent highly elevated structures, located 25 km south from the geothermal field. Production zones coinciding with dip angle fractures occur in the condition of radial extension (possibly caused by magmatic origin heat sources below the reservoir) and hydraulic fracturing (possibly caused by the elevated position of the Viluychinsky Volcano’s recharge region). TOUGH2 modeling of the thermo-hydrodynamic natural state and the history of exploitation (involving pressure, temperature and chemical changes response to utilization) between 1965 and 2014 yield estimates of hot water upflow rates (190 kg/s), the production reservoir compressibility (up to 4×10-8 Pa- 1) and permeability (up to 1.4 D). Modeling confirmed areal discharge of the thermal water from the production reservoir in the top groundwater aquifer (top Dirichlet boundary condition s). Modeling of the chemical (Cl-) history of exploitation provides an explanation of gradual Cl- accumulation due to the inflow of chloride-containing water through the eastern (open) boundary of the geothermal reservoirs. Modeling of the long-term exploitation until 2040 with an exploitation load of 256 kg/s merely shows a low pressure drop (0.7 bars) and an insignificant drop of temperatures in the production geothermal reservoir of the Paratunsky geothermal field.

    Valley of Geysers

    The field trip lasts 10 hours (from 9-00 to 19-00). The number of participants is up to 5. Map of the Valley of Geysers (Figure 4): IVS FEB RAS – Nikolaevka Airport – IVS FEB RAS (car); Nikolaevka Airport – Valley of Geysers – Uzon Caldera – Nalychevsky Hot Springs - Nikolaevka Airport (helicopter). Meals: box lunch & Malkinsky Water, swimming in the Nalychevsky Hot Springs.

    The trip costs 45 000 rubles per one participant. Prepayment on registration desk on Sept. 4th 2018 in IVS FEBRAS. The number of participants is up to 5. The priority to participate in the field trips is given to those who earlier submitted an extended abstract and PPT.

    The Geysers Valley hydrothermal system (Figure 4) is hosted within a system of two permeable faults (revealed by mapping thermal features), located above a suggested partially melted magmatic body and recharged by meteoric water along the outcrops of rhyolite-dacite extrusions. Fast erosion is stimulating the significant discharge rate, the geyser´s cycling mode and landslide events. Natural state thermal hydrodynamic modeling shows that 20,000-30,000 years of high temperature upflow of 250 kg/s and an enthalpy 900 kJ/kg can build up the hydrothermal system in Geysers Valley basin with output discharge parameters comparable to those at the current level. Modeling also shows that steam accumulation below an inclined caprock may have hydrothermal eruption potential. The Giant landslide took place on June 3, 2007, when 20 x 106 m3 of rocks were shifted 2 km downstream, more than 23 geysers were buried or submerged, and Podprudnoe Lake was dammed, injecting cold water into submerged geysers. Possible triggers of the Giant Landslide include the inclination of the sliding plane towards the Geysernaya river basin, a pressure increase in the fluid-magma system, hanging block saturation by water during spring flooding, hydrothermal alteration weakening of the sliding plane, and steam explosions.

    The monitoring of the Velikan and Bolshoy geysers after the catastrophic landslide on 3.06.2007 (which dammed and created Podprudnoe Lake, drowning some geysers) and before a mudflow on 3.01.2014 (which destroyed the dam and almost completely drained Podprudnoe Lake) shows that the interval between eruptions (IBE) of the Bolshoy Geyser decreased from 108 to 63 min and that the IBE of the Velikan Geyser slowly declined over three years from 379 min to 335 min. The seasonal hydrological cycle of the Velikan Geyser shows an increase in the IBE during winter (average of 41 min). The dilution of the chloride deep components of the Bolshoy (-17%) and Velikan Geysers (-12%) is also observed. A local TOUGH2 model of the Velikan geyser is developed and is successfully calibrated against temperature observations at both the mid-height and base of the conduit of the Velikan Geyser, which shows the essential role of the CO2 in the functionality of the geyser. A reservoir model of shallow production geysers is also developed. This 2D model is used to describe changes in the thermal hydrodynamic state and evolving chloride concentrations in the areas of most prominent discharge, both at steady state and when perturbed by cold water injection from Podprudnoe Lake and other cold water sources (after 3.06.2007). A “well on deliverability” option is used to model the geyser discharge features in the model. The modeled increases in geyser discharge that is caused by an increase in the reservoir pressure from cold water injection reasonably matches observations of IBE decreases in the Bolshoy (~58%) and Velikan Geysers (~9%).

    1941-2017 period of the Valley of Geysers monitoring (Kamchatka, Kronotsky Reserve) reveals a very dynamic geyser behavior under natural state conditions: significant changes of IBE (interval between eruptions) and power of eruptions, chloride and other chemical components, and pre-eruption bottom temperature. Nevertheless, the total deep thermal water discharge remains relatively stable, thus all of the changes are caused by redistribution of the thermal discharge due to Giant Landslide of June 3, 2007, Mudflow of Jan. 3, 2014 and other events of geothermal caprock erosion and water injection into the geothermal reservoir. In some cases, water chemistry and isotope data point to local meteoric water 9 influx into the geothermal reservoir and geysers conduits. TOUGHREACT V.3 modeling of Velikan geyser chemical history confirms 20% dilution of deep recharge water and CO 2 components after 2014. Temperature logging in geysers Velikan (1994, 2007, 2015, 2016, 2017) and Bolshoy (2015, 2016, 2017) conduits shows pre-eruption temperatures below boiling at corresponding hydrostatic pressure, that means partial pressure of CO2 creates gas-lift upflow conditions in geyser conduits. Velikan geyser IBE history explained in terms of gradual CO2 recharge decline (1941-2013), followed by CO2 recharge significant dilution after the mudflow of Jan. 3, 2014 also reshaped geyser conduit and diminished its power.
