navigate, on-demand insights. These solutions leverage the
cloud and mobile devices to bring frac and wireline analytics
to completions teams wherever they are, enabling on-site and
back-office staff to share a common operational view and optimize completions in real time with a tablet, phone or laptop.
Mining Offset Data
Frac treatments in the four corners of a county often yield
completely different results, so there is no one-size-fits-all approach. Treatments must be tailored to local conditions and
rock fabric variability. Wells in a nearby offset field often hold
the key to optimal proppant, fluid and pressure ratios for the
target pad. And with the downspacing seen in the Haynesville,
parent wells are abundant, which translates to vast volumes of
historical offset data. It can take weeks for offset completions
data to be gathered and analyzed for treatment best practices
and optimal set points.
Rockcliff's completions engineering staff members now
mine this large volume of offset well data in seconds with
cloud-base analytics that instantly organize pad metrics. Leveraging the technology, the company can build a completions
roadmap tailored to the unique requirements of each pad
quickly, leveraging best performing treatment set points. What
worked best for an offset well pad a year ago could be
leveraged and the treatment best practices adapted for the
current pad. This iterative process of capturing completions
metrics for every stage, well and pad provides a continuous
improvement loop as treatment best practices are leveraged

and refined for a region over time.
Because Rockcliff drills multiwell pads and zipper fracs as
many as four wells at a time, keeping a close eye on operational
progress is traditionally only possible with staff sitting in the
frac van and wireline logger. During the completions operation,
one well is fractured while the wireline crew plugs and perforates
the next well, keeping equipment and crews in constant action.
For off-site staff and completions engineering teams, there is
limited visibility into these ongoing operations, making it
difficult to monitor progress and troubleshoot.
Rockcliff is leveraging its completions analytics platform to
track pad progress in real time. Engineering staff members
simply access a pad progress app from a device of choice,
which provides quick-look analysis, including frac and wireline
status, swap-over times, day and night shift performance, and
other KPIs. The technology also enables Rockcliff's team to
quickly drill down to detailed measured depth versus total
vertical depth visualizations for a specified range of stages and
to view dogleg severity, rate of penetration, and log curves
(Figure 1).
Optimizing Chemical Usage
Cross-linked gels, friction reducers and other frac additives
are not cheap, but they are necessary to improve flow rate. In
general, the industry overtreats and without reliable data on
optimal chemical set points, it is like pouring money down
the drain.
How slick does a slickwater frac really need to be? That is a
