Based on the modeling of non-isothermal fluid filtration, taking into account the Joule–Thomson effect and the adiabatic effect, the formation of temperature in a porous medium with radial-angular permeability heterogeneity is studied. It is shown that the presence of heterogeneity in the near-wellbore formation zone leads to different rates of temperature establishment in the angular distribution after the well is put into operation. Depending on the ratio of the permeability of the formation and the area of heterogeneity during fluid filtration in the angular distribution of temperature in the well, either a slow rate of temperature establishment in the region of heterogeneity is observed. The area of heterogeneity is colder than the rest of the area, or vice versa, the area of heterogeneity has an increased temperature. The results obtained complement the known data on the formation of temperature fields in reservoir conditions with non-isothermal fluid filtration, taking into account thermodynamic effects, and can be used to interpret the results of multi-sensor temperature studies in wells with formations that are heterogeneous in permeability.

“…Under the condition of no layers communication, they found that the temperature response is sensitive to the damaged zone radius and permeability. Valiullin et al (2014) applied similar models to compare the numerical results with field data, as well as the data obtained from deviated wells. The inversion process to achieve multilayer reservoir characterization required all available field data.…”

Multilayer systems are widely encountered in underground hydrocarbon reservoirs. To obtain accurate multilayer properties and understand the flow behavior in a multilayer system, many testing and analysis procedures have been evolved. Recent developments on downhole temperature monitoring systems open new alternatives contributing to multilayer reservoir characterization. The progressing technique, temperature transient analysis, is developed to use the temperature data, which are unique for each layer in a multilayer reservoir.In this work, we present an analytical solution to determine the individual layer temperature signal associated with constant rate production of slightly compressible fluid from a fully penetrating vertical well in a multilayer reservoir. The analytical solution development process involves identifying the late time individual layer production rates and applying the single layer transient temperature behavior, the results of which are benchmarked with those from the numerical simulation. The temperature signals are presented at the bottom-hole location and further into the reservoir for two-layered and multi-layered systems, for which each layer may be damaged or undamaged. The temperature profiles obtained from analytical solution shows excellent agreement with those from numerical simulation and are sensitive to layer permeability, porosity, and damaged zone properties. In addition, we provide semi-log temperature interpretation techniques to characterize the layer permeability and porosity, and damaged zone radius and permeability considering the availability of adequate data. The simplified characterization methods are also developed in the case of insufficient or inaccurate data to obtain permeability and production rate ratios between layers which helps to identify the layers contributing the most to well production.

The goal of this paper is demonstration of an approach to enhancing reliability of quantitative interpretation of well tests data. The new approach comprises joint interpretation of transient temperature, pressure and flow rate data taking into account flow rate history before the test. It provides additional information about near-wellbore zone, flow profiles and hydrodynamic properties of a multilayer reservoir. The transient model for solving the coupled thermal-hydraulic problems in the reservoir, formation, and wellbore is described in the paper. It takes into account heat convection and conduction, Joule-Thomson, adiabatic effects, thermal effect caused by degassing as well as mixing of fluids in the well, heat transfer between wellbore fluid and formation, frictional heat release and thermal effect of fluid compression or expansion. This model allows simulating flow behind casing, crossflows during shut-in and different properties of the near-wellbore zone. Transient temperature and pressure fields, and temperature profiles along the wellbore are simulated for a given flow rate history. The model parameters are determined by solving the inverse problem based on a comparison of simulated temperature data with measurements in the wellbore. Application of new approach to quantitative interpretation of well test data and developed transient numerical code are demonstrated on the example of field data from the Bashneft - Polus oil well. The data from production logging during flow at different choke sizes and transient station measurements of temperature and pressure after change of regimes are available and simulated with the developed code. Standard Pressure Transient Analysis (PTA) was used for pressure and flow rate data interpretation, while available temperature measurements were simulated with a numerical code developed for solving the coupled thermal-hydraulic multiphase problems by Bashkir State University and Schlumberger Moscow Research center. The paper demonstrates the results of quantitative interpretation of the field data and sensitivity study of the model parameters to uncertainties in measurements, flow rate history, thermal properties and other input data.
