Multizone Cased Hole Completions

Overview Library

Perforating, fracturing, and gravel packing

In complex reservoirs, our multizone completion systems improve both efficiency and recovery. Multiple zones can be isolated and treated independently or in a single pumping operation, with either commingled or selective production.

Stacked completions—zones treated separately in multiple trips

Stacked completions consist of a series of single zones treated separately. Multiple trips are required to deploy the perforating and sand control tools and to clean the well. Both the QUANTUM gravel-pack system and the QUANTUM MAX system for higher pressures and temperatures can be used, alone or with Alternate Path technology. The first zone can be completed using the QUANTUM PERFPAC or the QUANTUM MAX PERFPAC single-trip perforating and gravel- and frac-packing system.

MZ-Xpress system

Multizone gravel or frac packing can also be done in a single trip after the well has been perforated. Zones are isolated and treated individually. The MZ-Xpress system for performing multizone fracturing and gravel packing in a single trip is used for this approach—alone or with Alternate Path technology.

Projected Revenue in Subsea Project Increases by USD 20 Million Using Integrated Completions Technologies in Indonesia

The Multizone Alternate Path system and QUANTUM PERFPAC system increased recoverable gas reserves between 6 to 10 Bcf and production by 10 MMcf/d, boosting projected revenue by a total of USD 20 million. Read case study

One treatment after perforation—in a single trip

Multizone gravel or frac packing closely spaced zones in one trip can also be performed using a single pumping operation after the well has been perforated, resulting in significant cost and rig-time savings. The Alternate Path multizone packer—a cup-type packer with Alternate Path shunt tubes extending through it—is used as part of the AllPAC or AllFRAC screen assembly to provide isolation between the zones.

One treatment and perforation—in a single trip

Combining the Alternate Path packer with the QUANTUM PERFPAC system enables multiple zones to be perforated and gravel or frac packed in a single treatment—all in one trip. This combination of technologies is unique in the oil and gas industry.
