A Single Second
It takes a minute to write a safety rule.
It takes an hour to hold a safety meeting.
It takes a week to plan a good safety program.
It takes a month to put that program into operation.
It takes a year to win a safety award.
It takes a lifetime to make a safe worker.
A Single Second
But it takes
only a second
to destroy it all - with one accident.
Take the time now to work safely and help your fellow employees to be safe.

Single Trip Multiple pletion SystemsIntroduction
What is a Single Trip Multi-Zone System?
A multiple zone system plishes the same objectives as a stack pletion
The perforating for all zones is done in one trip with TCP or multiple trips with wire line. All zones are perforated first.
The well is cleaned up
pletion tools are run for all the zones in a single trip.
The packing operations pleted in the same trip.
Each zone can be isolated selectively or mingled.
When do you run a Multizone System?
Long zones with multiple lobes that need to be broken up
Isolation of discrete zones
Production Control – all at once or one at a time
Water Shutoff – close off as they water out
Increased Speed of packing multiple zones
Reduced Rig Time
Lower Overall Cost
When should a Multizone System not be Run?
Varying Fluid Gradients - BHP Differences between zones
Difficult to Control Wells - can not be easily controlled for sand and gas influx.
Closely Spaced Zones (between perforations)
Less than 7 meters for STMZ
Risk…..?
