TOTAL PROTECTION BYPASS SYSTEMSBypass completion systems enable access below the ESP with no workover requirement, allowing access to perforationsand logging with wireline or coil tubing. In addition to the benefits of the standard Zenith ESP Bypass system, inclusion offurther unique technologies in our patented Total Protection Bypass system offers advanced protection for your ESP.TOTAL PROTECTION BYPASS SYSTEM BENEFITSAuto Flow ValveProtects ESP; sand divert — no backspin, pump shut-down — fluid column drains through annular portsEnables production gains; continued natural flow through annular ports when pump is switched offUnique shut-off featureSwivel Nipple AssemblyEliminates possibility of back-offMake-up ShoulderImproves safety; prevents bypass tubing slippage during make-upBypass TubingStandard lengths; no specialist lengths required for space-outWhen two plus two equals more than four — the Total Protection Bypasssystem provides all the benefits of individual Zenith technologieswrapped into a one-stop package enabling reservoir access beyond theESP, sand diversion on shut-down, eliminating backspin, reducing wirelineruns and comprehensive monitoring of the downhole completionand pump.Cable Support ClampsAllow for thermal expansion of ESP; non-gripping on bypass tubingMinimise inventory; same clamp for different casing weights, single cable-clip suits a range of MLE sizesE-Series SensorMaximises runlife while reducing costs; safeguards and controls your system with alarms & trips, protecting the pump & wellIndependent source of accurate data for analysisOptimises production; surface package allows automatic or remote controlSaddle AssemblyEliminates risk to the ESP;accommodates thermal expansion preventing damage to the ESP, passes compression forces on to the Y-block—no load on the ESPReduces installation time; saves rig time & associated costsEliminates complicated space-out; allows 8ft of bypass tubing movement

TOTAL PROTECTION VALVE SYSTEMInstall the combined valve and Y-block blanking plug as one unit to give you all of the benefits of the Auto Flow Valve plus:Logging operations are the same as a standard bypass system:» Run #1: Pull the combined valve and Y-block blanking plug» Run #2: Run/pull production logging tool plus Zenith combined logging plug and valve» Run #3: Finish logging and reinstall the combined valve and blanking plugThe ESP will be fully protected by the Zenith Auto Flow Valve while loggingSwivel NippleY-BlockPorted NippleRunning in-hole.Flow divert pluginstalled.Naturally flowing.Flow divert pluginstalled.ESP operational.Flow divert pluginstalled.ESP shut-down.Flow divert pluginstalled.ESP operational.Wireline logging pluginstalled.ESP shut-down.Wireline logging pluginstalled.ZENITH
