ROCK PROPERTIES Clause Samples

ROCK PROPERTIES. ‌ The focus of this work is to estimate the static formation temperature profile along the wellbore. Hence, the rock properties necessary for the simulator are assumed constant and known. These values are taken from Gudmundsdottir et al. (2013) who investigated the Reykjanes geothermal system using a coupled wellbore-reservoir simulator. Thermal conductivity of basalt λe 2 W/mK Specific heat capacity cP,e 1000 J/(kg⋅K) Rock density ρe 2650 kg/m3 According to ▇▇▇▇▇▇▇▇▇ et al. (2014), these values are possible for basaltic rocks. ▇▇▇▇▇▇▇▇▇ et al. (2014) give two values for the thermal conductivity of basalt. The first one is 2.11 W/mK and corresponds to the average of several publication data. The second one is 1.69 W/mK and is provided by ▇▇▇▇▇▇ (1997) who claims a suitable range between 1.12 and 2.38 W/mK. Furthermore, ▇▇▇▇▇▇▇▇▇ et al. (2014) list two different values for the specific heat capacity 840 J/(kg⋅K) and 1230 J/(kg⋅K). The sensitivity of the simulation to each of these properties is presented in Section 3.3 “WellboreKIT validation on RN-15 well logs and sensitivity analysis”.
