is far greater than the minor cost of deployment.
The example in Figure 2 shows how
measured BHP can be used to identify
root causes of well underperformance by
analyzing pressure buildup during unexpected shut-ins associated with operational
issues. The two gas-lifted horizontal wells
had similar geology, drilling practices,
landing intervals, and completion designs,
but were flowed differently to test the
impacts of managed drawdown.
Well No. 1 was flowed aggressively
with no drawdown management, while
well No. 2 was flowed conservatively
through the extended use of chokes. Interestingly, the well with more drawdown
not only had a higher rate, but also higher
productivity, which was opposite of what
had been observed in several other shale
plays.
Because of operational issues, both
wells were shut in and BHP was monitored
during extended pressure buildups. Loglog plots of pressure and pressure derivative versus time revealed that well No.
2 (with managed drawdown) had inter-

preted skin damage, as indicated by the
increased separation between the pressure
and pressure derivative curves, compared
with well No. 1.
While this was one of several key
field trials that supported a flowback
strategy decision for all future wells, it

also demonstrated the applicability of
using real-time BHP monitoring to identify
near-wellbore damage during shut-ins.
