The active building of HW with MSHF use for ensuring their effective development in low-permeability reservoirs, but there are certain difficulties with getting completely information for making the right decisions during control of development.

As part of the work performed, the main uncertainties and the further application of research results for estimates the profile of horizontal well (HW) with multi-stage hydraulic fracturing (MSHF) for planning the necessary geological and technical actions based on more than 20 operations at the South Priobskoye field are shown.

The following field geophysical tests were executed in wells:

  • PLT with Y-tool and CT + spectral noise logging module;

  • PLT during compression with CT + multi-sensor flow meter;

  • PLT with a well tractor;

  • tracer studies (proppant, frac sleeves);

  • thermometry with using fiber-optic system in injection and production wells.
