MRP-2CEV-2BT-TMU WITH SHROUD

This patented remotely controlled completion system used in multi-reservoir production (MRP) includes one-packer and ESP unit with shroud for simultaneous production from two reservoirs through a single tubing string. The completion system provides parameter measurement and flow control separately for each fluid flows entering the section of an ESP.

Applications:

• For cost reduction in multi-reservoir fields;
• Production wells penetrating reservoirs with different properties and differences in burial depths;
• 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.

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 *;
• Dynamic testing of each reservoir during ESP operation with recording of pressure build-up curves by shutting in one of the reservoirs;
• The completion is run and set in the well in two stages: (1) setting PIM -2F packer system and (2) running two CEVs with their TMUs, and an ESP for connection to the packer system;
• ESP with CEVs and TMUs is removed from the well without lifting the packers;
• 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.
