The article provides an analysis of shale oil production and artificial lift equipment world market for choosing the optimal method for oil production from the Bazhenov formation. The result of the analysis is the identification of prospective complexes of artificial lift (wellhead and downhole) equipment that meet the following conditions:
• artificial lift equipment is used in operating conditions that are similar to those, which planned for the Bazhenov formation development: for wells with a long horizontal wellbore and multi-stage hydraulic fracturing; conditions similar to the Bazhenov formation in terms of the depth of the deposit, production volumes (production curve, initial flow rates, gas-oil ratio (GOR), reservoir temperature, etc ).;
• the properties of the produced fluid are similar to the Bazhenov formation reservoir fluid (light oil, GOR increase over production time, water cut drop over time, etc.
Analysis includes wellhead equipment, downhole equipment, and control stations for wellhead and downhole equipment.
Based on the analysis results, the main selection criteria are given, a comparative analysis of the main types of artificial lift equipment is carried out, and promising types of artificial lift for oil production from the Bazhenov formation are identified.
