is it possible to perform a multi-entry ball-activated fracture sleeve job? - ANSWERSyes
With the ball-activated completion system (BACS), which size ball is fun at the toe of the well -
ANSWERSsmallest
Assuming no operational issues, does the frac job shut down between stages with a ball-activated
completion system (BACS)? - ANSWERSno
which of the following can be used for annular isolation for the ball-activated completion system (BACS)?
- ANSWERScement, hydraulic-set openhole packers, fluid-activated open hole packers
is it possible to do multi-entry points that mimic plug-and-perf clusters with ball-activated completion
system (BACS) - ANSWERSyes
is wireline a required service when using the coiled-tubing-activated completion system (CTACS) -
ANSWERSno
which tool is a requirement to be able to execute out-of-order fracturing with coiled-tubing-activated
completion system (CTACS) - ANSWERSreclosable coiled-tubing-activated fracture sleeve
which methods are used to provide annular isolation for the coiled-tubing-activated completion system
(CTACS)? - ANSWERSeither open hole packers or cement
which component is used to provide through-tubing isolation from the previously fractured stage when
using coiled-tubing-activated completion system (CTACS) - ANSWERScoiled tubing packer
, An operator is using the old rule of thumb of fracturing at 2 bpm per perforation and using 50
perforations per stage. How many bpm are required at surface? - ANSWERS100
After further evaluation of the formation, they discover that 90% of the minimum horizontal stress
variability is within an 800-psi range. Using 100 bpm, what is the issue with the amount of perforation
friction pressure in correlation to the stress variability? - ANSWERSthe perf friction is not high enough to
overcome the horizontal stress variability, and some perforations will not open
what is the limitation of the number of perforations per stage using plug-and-perf? - ANSWERSthe length
of the wireline assembly at the surface
what is it the most common way to deploy plugs into the well with a plug-and-perf system -
ANSWERSwireline pump-down
is it possible to perform a single-entry plug and perf job? - ANSWERSyes
near wellbore diverters are used to improve fluid distribution in multiple entry applications by isolating
the perf(s) that are dominating the fractures and divert the fracture fluid into the non dominant perfs -
ANSWERStrue
when using wireline to deploy the plug, what sets the frac plug - ANSWERSelectric pulses through the
wireline
what are the benefits of simultaneous fracturing operations aka zipper fracturing with plug-and-perf -
ANSWERSminimize nonproductive time for pressure pumping, minimize nonproductive time for wireline,
improve overall surface efficiency during the frac
which of the following are benefits of using the dissolvable frac plug - ANSWERSdissolves in the wellbore
fluids and removes itself from the well, enables PNP in longer laterals because they do not have to be
milled out, eliminates mill-out of the frac plugs after the frac job
what is the limited-entry perforating technique trying to improve - ANSWERSdistribution of fluids and
proppants through each perf cluster
