Welltest 105: Thermal Data Diagnostics

Thermal Interference Demonstrated Beyond 50 m Radius. Such extensive alteration of reservoir temperatures suggests that a considerably long time might be required for the formation to return to insitu thermal equilibrium. Temperature recoveries lasting in excess of 1000 h been observed from the data provided by electronic pressure gauges. Moreover, such non-isothermal conditions might have implications on quantitative #PTA modeling results such as skin, permeability, and transient #gas (#LNG) deliverability forecasts, as all equations assume  isothermal conditions. It may not be possible  to quantify the effect of non-isothermal conditions on analytical results.
