... and Cinar (2017a) . It should also be noted that Eq. 11 will be used to obtain the wellbore temperature solution above a gauge location above the producing horizon, as to be discussed in the next section. Buildup Sandface-Temperature Solution. Here, we present a new buildup sandface-temperature...

... and momentum and reservoir pressure diffusivity equations and thermal energy balance equations in the wellbore and reservoir can be decoupled. The semi-analytical solution for predicting sandface temperatures is verified by use of a general purpose thermal simulator. Wellbore temperatures at a certain gauge...

... inflow profile is then constructed using the history matched layer permeability and skin values. In addition to the wellbore temperature profiles, temperature and pressure profiles within the reservoir will be shown which illustrate the relative impact of the reservoir permeability and skin...

Some field examples are provided to demonstrate these applications. production monitoring wellbore temperature radial direction Reservoir Surveillance temperature distribution gauge location transient temperature behavior application...

... in the defined system. The results indicate that the wellbore temperature is primarily sensitive to fracture geometry (fracture half-length). It is possible to interpret the fracture geometry using temperature data after the flow rate is stabilized after certain period of production. In addition, wellbore...

... The solutions of Eqs. 11 to 17 provide the temperature and pressure distribution in the wellbore. Coupled Reservoir and Wellbore Temperature To solve temperature equations, Eqs. 9 and 11 , we must know the arriving temperature T I , which is the link between the reservoir grid temperature...

... several different analytical solutions for wellbore temperature. Some of these solutions have been developed previously, though they are nonetheless included here for completeness. Following this presentation, we describe the wellbore flow equations and the semianalytical treatment. We proceed...

... in near wellbore temperatures due to Joule-Thomson expansion of the reservoir fluids and, 2) significant reductions in oil viscosity. The effects of large drawdown are evaluated with a transient, single-phase thermal simulator in which the oil viscosity is modeled as both temperature and pressure...

... to date has been limited to the discussions resulting from the examination of steady-state temperature profile behavior, significantly more knowledge and better assessment of "what's happening" in wells can be gained when sequences of complete wellbore temperature profiles are analyzed during rate-related...
