STMZ-FP System History • Low Pressure system - 9 5/8”4.00 bore (STMZ, STDZ, DTMZ) • Low Pressure System - 7”3.25 bore (DTMZ, STDZ) • Excessive Seal Damage • Tool Sticking • Load Collet to position the tool • Low pressure (2-3000 psi) Isolation packers • Low Pum rates ( 12 BPM) STMZ-FP System Current Status • New Quadra Seals for Improved life and reduced sticking • Higher Pressure 9 5/8”4.75 bore system (5,000 psi) • Weight down ShurMAC Multi-Acting Collet • Higher Frac Rates STMZ-FP System - Run Lower Service Tool STMZ-FP System - Hang the lower seal unit with the lower service tool in the slips STMZ-FP System - Run the upper completion tools and screen. Run washpipe to latch the lower service tool. STMZ-FP System STMZ-FP System - Latch the washpipe to the lower service tool STMZ-FP System - Pull the service tool into position STMZ-FP System - Set the slips and remove the latching mechanism STMZ-FP System - Run the inner concentric string (Inner Tube for MPA) STMZ-FP System - Sting in and test the inner string (fluid level test only) STMZ-FP System - Attach the packer assembly STMZ-FP System - Be sure the Crossover Ports are below the lower MCS STMZ-FP System - Run to bottom and sting into the sump packer. Snap in and out to be sure. STMZ-FP System - Drop the setting ball and set the upper packer STMZ-FP System - Pressure up and expend the setting ball STMZ-FP System - Setting ball lands below the crossover - may reverse out - have a catcher in the lines. STMZ-FP System - , pressure up and set the isolation packers STMZ-FP System - Pack one zone at a time STMZ-FP System - Packoff seals the upper annulus. Circulation is possible STMZ-FP System - lower zone packed STMZ-FP System - packing subsequent zones. Collet in position. STMZ-FP System - Returns and pressure monitoring above the upper zone. STMZ
