The complexity of solving the problems of monitoring the development in multilateral horizontal wells based on the results of well logging is associated with the multiphase flow, the influence of gravitational phase redistribution along the well cross-section, different flow rates of the phases, non-monotonicity of the wellbore trajectory (the presence of ascending and descending sections in the casing), phase inhomogeneity, which occurs both along the section and along the length of the well, and with the delivery of a geophysical device into the horizontal wellbore. Under these conditions, the use of standard technologies and equipment for conducting well logging is ineffective.

The article presents the experience of conducting and interpretation of well tests on multilateral horizontal wells, and also selected a complex of well logging cases.

Key words:
