MRP – 2ESP – 2TMU – ST

This patented remotely controlled completion system used in multi-reservoir production (MRP) includes two packers and double-sided ESP unit for simultaneous production from two reservoirs of horizontal side-track (ST) through a single tubing string. The completion system provides separate parameter measurement of the fluid flow coming from two reservoirs of side-track’s tail to an ESP intake.


  • For cost reduction in multi-reservoir fields and wells penetrating reservoirs with different properties;
  • For tapping currently inactive reservoirs;
  • For solving problems associated with drawdown pressure limits or negative mutual interference between reservoirs;
  • For simultaneous production from multiple reservoirs with different physicochemical properties, production fluid characteristics, water cuts, gas-oil ratios, bubble-point pressures and temperatures.


  • The entire completion, including controlled electric valves (CEV), is controlled in real time remotely or from Geonik’s control station;
  • Two-way communication to obtain fluid data from 2Telemetry units (TMU) with P, Q, C, T gauges during operation of an ESP from Geonik’s dedicated telemetry system (TMS) or through power or logging cable by personal request*;
  • The completion is run and set in the well in two stages: 1) setting two-packers system and (2) running double-sided ESP with 2TMUs and its connection to two- packers system;
  • To wash downhole pumping equipment by reagent injection from the wellhead, both direct and reverse circulation can be performed;
  • To change an ESP, the main system is retrieved from the well without the packer system;
  • No additional tubing used for production from multi-completion wells with hydraulic valves is required due to ease of installation and high performance of the completion system.
