Expanding the share of unconventional oil and gas reserves involvement shifts the focus to analyzing well productivity increases. The cost of horizontal wells stimulation for increasing oil recovery rate carried out using multi-stage hydraulic fracturing is much higher. This requires the involvement of new technologies and services to facilitate optimal drilling, completion and stimulation returns. The use of developed technology to determine inflow profiles allows oil and gas producing companies to efficiently determine well productive intervals, thereby indicating high production rates and maintaining the profitability of facilities put into operation by eliminating non-productive intervals. These data allow planning field development with higher profitability due to increasing the oil recovery rate.
