Revo Testing Technologies' software automatically performs rate transient analysis on
wells' production data. The company says this helps operators optimize reservoir
drawdown to recover oil and gas as quickly as possible without reservoir damage.
into the fracture system before frac water
has been cleaned out. This can leave
water locked inside the fracture system,
limiting its hydrocarbon conductivity, "
Tompkins adds. " Overly-aggressive pressure
drops also may close far-field fractures
that are being held open by pressure. "
In an unconventional well, the drawdown
rate can change every four hours, says
Christina Costello, Revo's executive vice
president of business development. " To
show when a change needs to be made,
the software uses colors. Green means
drawdown can be accelerated, while red

means it needs to be restricted, " she illustrates.
" This makes it easy for both engineers
and field hands to see when they are producing
the well as aggressively as possible
without causing damage. "
Other Insights
Revo CEO Adam Swartley emphasizes
that the company's software has unique
capabilities. " The traditional rate transient
analysis techniques that most commercial
software programs implement are tailored
for long-term data, " he says. " We have
been working with academia to create
cutting-edge physics-based models so
we can use flowback data to provide
more insights. "
Tompkins says that work is paying
off. " We are adding features now that
can give a complete characterization of
the subsurface conditions with limited
production data. In unconventional wells,
we only need 30 days' data to characterize
the reservoir, infer the frac geometry and
estimate total production.
" Our models also can detect subsurface
issues, " he adds. " For example, we can
