Single-Trip Multizone (STMZ™) System
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.
