Simultaneous Stimulations and/or Packing in Multiple Zones. Effective Solutions.

摘要

This paper describes 12 history cases of the successfulrnapplications of Alternate Path (shunt tube) Technology inrnwells in Bachaquero Lago, Tía Juana Lago and Lagomediornfields, in Lake Maracaibo.rnThe use of divergent tubes combined with packoff in thesernwells, allowed to complete two zones in a single triprn(stimulation or packing in the superior zone and packing in therninferior zone), reducing the number of pipe trips in each wellrnand therefore, reducing the operational risks and drilling costs.rnThis type of completion will also allow independent isolationrnin anyone of the zones in the event of watering problems,rnallowing selective production.rnIn all the cases, successful gravel packing were achievedrnas well as 45% saving in drilling time, compared withrnconventional completion. In all the cases productivity wasrnhigher than the initial estimate, without formation sandrnproduction, confirming the success of the application.rnThis technology provides a reliable and profitablernalternative for the completion of two or three simultaneousrnzones.
