Increasing the commercial drilling speed of a horizontal well
Determination of optimal zones for laying gas wells in a carbonate reservoir
Object: Gas field. Carbonate reservoir. CIS.
The purpose of the work is to determine the optimal zones for laying appraisal wells in the field.
The problem: High heterogeneity of poroperm properties, "dry" wells.
Reed moreCalculation of the stability of the cutting interval in an open horizontal borehole during the construction of multi-lateral wells
Object: Multi-lateral wells of the "fishbone" type. Oil and gas condensate field. Leno-Tunguska oil-and-gas province, Russia.
Issues: Numerous overpulls, landings. The failure of the BHA to enter the lateral borehole. Loss of lateral borehole.
The purpose of the work: To prevent complications in the area of articulation of the parent and lateral boreholes, to reduce the unproductive time.

Object: Horizontal wells. A gas condensate field. West Siberian oil-and-gas province, Russia
The purpose of the work: Preventing complications and reducing the construction time of horizontal sections
Issues: 4 horizontal wells have been drilled at the field with an average drilling time of 90 days for the horizontal part. A large number of complications: absorption, seizure of the drilling tool. The loss of the horizontal holel and the drilling of the section under the shank.
Reed moreDetermination of the mechanical properties of the rock in formation conditions
Object: Achimov deposits. West Siberian oil-and-gas province, Russia.
The purpose of the work: Determine the mechanical properties of the rock corresponding to the conditions of occurrence throughout the section.
Issues: The lack of results of core studies on mechanical properties in non-reservoir rocks; the results of previously conducted core studies do not reflect the properties of the rock under reservoir conditions.
Reed moreImproving the efficiency of processing the bottomhole zone of a carbonate low-permeability formation
Object: Gas field with HP/HT low-permeability carbonate reservoir. CIS.
The purpose of the work: To increase the flow rate of the well by hydrochloric acid treatment of the well bore zone.
Issues: The low efficiency of the treatment with hydrochloric acid.
Reed moreDevelopment of an optimal hydraulic fracturing design taking into account the individual geomechanical properties of each stage
Object: Achimov deposits. West Siberian oil-and-gas province, Russia.
The purpose of the work: To develop a hydraulic fracturing design without the risk of a crack breaking into an aquifer.
Issues: Potential rupture of fractures of hydraulic fracturing into the aquifer.
