MRP – ESP – ESM – ESP – 1CEV – 1TMU

This patented remotely controlled completion system used in multi-reservoir production (MRP) includes one double-grip packer PIM-2F and double-sided ESP unit for simultaneous production from two reservoirs through a single tubing string. The completion system provides parameter measurement and flows control coming from lower reservoir via lower section to an ESP intake.

Applications:
• 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;
• For possibility to use this completion system with shroud to prevent overheating of ESM.

BENEFITS
• 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 Telemetry units (TMU) with P, Q, C, T gauges and precise opening / closing regulation of electrovalves 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 double-grip PIM-2F packer system and (2) running double-sided ESP with TMU and CEV unit and its connection to the packer system;
• Dynamic testing of each reservoir during ESP operation with recording of pressure build-up curves by shutting in lower reservoir;
• To change an ESP, the main system is retrieved from the well without the lower packer system;
• To wash downhole pumping equipment by reagent injection from the wellhead, both direct and reverse circulation can be performed;
• 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.
