Quantitative interpretation of data from flowmetric studies of horizontal wells: problems and opportunities

Recently, in connection with the expansion of the hardware and methodological complex in field-geophysical studies (PGI) of horizontal wells, more and more attention, along with the traditional qualitative interpretation of PGI data, is paid to the quantitative determination of parameters, such as the inflow profile, interval flow rate, etc. One of the main approaches in this case is the use of mathematical models and the solution of inverse problems for the quantitative assessment of the relevant parameters based on the processing of the initial data of field-geophysical studies at different operating modes of the well. The most complete information is obtained when using multi-sensor devices with distributed moisture meters and temperature sensors, as well as systems with length-distributed temperature and pressure sensors, as well as fiber-optic technologies. Some approaches for quantifying phase flow rates and the inflow/uptake profile from flowmetric studies are discussed below.
