.../Scope The bottom hole circulating temperature of horizontal wells can be higher than those of vertical wells. That risk is compounded in HPHT slim-hole applications where static geothermal temp can reach 320°-350° F. The combination of horizontal wellbore geometry, HPHT conditions, and slim-hole design...
