ibrate the required gas-to-liquid ratio with
the system versus the standard plunger
lift design parameters. The system performed efficiently and as expected, with
consistent plunger arrivals and no system
"stalling." The liquid production rate was
higher than previously experienced. Liquid
slug size per plunger cycle was significantly above what was expected based
on design calculations for a traditional
plunger installation.
A second, yearlong trial of a slickline
system in the Permian Basin's Wolfcamp
play also incorporated continuous plunger
lift. Three wells owned by a single operator were included in the second trial.

These producing wells were located near
one another in Irion County, Tx. The
typical true vertical depth of the operator's
wells in the area is in the 6,000-7,000
foot range. The typical initial production
rates of the wells ranges between 1,000
and 4,000 barrels of fluid a day, with
water cuts averaging 50-75 percent after
initial post-fracturing cleanup. These
wells do not usually flow naturally, so
gas lift is employed to achieve the very
high IPs.
Figure 3 shows that the first well was
initially gas-lifted, and then transitioned
to rod lift prior to installing the slickline
system. When transitioning to rod lift, a
