“…The knowledge of the thermal phenomena (heat flux and temperatures) is essential for many areas of engineering and scientific research: (a) reservoir engineering (hydrocarbon recovery factors); (b) well completion and production logging (Fialka et al, 1990;Hill, 1990;Jutten and Morriss, 1990;Wooley, 1980), such as production of hydrocarbons and geothermal energy, and in the study of groundwater and aquifer potential (casing cements, completion design, fluid flow, and evaluation of fractures); (c) evaluation of thermal conductivity of the formation (Conaway and Bek, 1977;Reiter et al, 1986), (d) detection of overpressuring zones (Fertl and Leach, 1990); (e) exploration for energy minerals such as petroleum and coal (Hill, 1990); (f) paleoclimatology (Harrison, 1991); and (g) study of the Earth's evolution (Sass et al, 1992), among others. Also, knowing the thermal phenomena to predict the temperature distribution in an oil field can be a main element in the thermal recovery of the deposit (e.g., Centeno-Reyes, 2009, 2010).…”
