Rig time savings
Use of the MZ Alternate Path system saved an estimated 12 days compared with a conventional stacked sand control method. The time savings was a result of perforating all the zones together, installing all of the sandface tool hardware in a single trip, and pumping simultaneous gravel- and frac pack treatments. Risks were also reduced by eliminating multiple trips in and out of the borehole.
An estimated 2 days of additional rig time savings resulted from combining the perforating and sandface tool assemblies (that is, using the QUANTUM PERFPAC system) into a single trip into the well. In one trip, all three intervals were perforated, the toolstring repositioned, the packers set, and the single pumping treatment performed. The need to remove the perforating string from the wellbore before running the sand control tool assembly was eliminated. In addition to reducing the completion time associated with an additional trip to remove the perforating string, this technique eliminated the cost and time to place and eventually remove a fluid loss control pill and productivity impairment resulting from the fluid loss control pill.
