Halliburton is the leader in multizone systems that enable the isolation and gravel packing of all zones that require gravel pack for sand control in fewer trips. The basic single-trip multizone (STMZ™) system has reliably run hundreds of times since 1993 and is designed to provide treatment options ranging from annular gravel packs to low pump-rate frac packs.
7-in., 7 5/8-in. and 9 5/8-in. systems
Burst, collapse and differential rating of 6,000psi
Petronas Carigali Vietnam Limited (PCVL) needed to complete four wells with two or three zones per well that required gravel pack and reduce rig time to minimize the time-to-completion of each well for a sand control project in Vietnam.
The article explains the single-trip multizone sand control system that gives operators the ability to complete, monitor and
control multiple zones within wells, without mechanical intervention and minimising its associate risks & costs.
